그만큼 LED transparent screenis no stranger in our life. How does the LED transparent screen help the physical store to improve the passenger flow? Let’s talk about it today.
Led transparent screen, also known as transparent LED display, ice screen, is an extension of LED display. It is usually used in combination with glass or can be used independently. It seems that led transparent screen was born for the display window of physical stores. The gold jewelry industry first used LED transparent screen. The decoration of gold jewelry stores is magnificent, very tall, and usually has window glass, so that customers outside the store can see the exhibits and the situation in the store when passing by. The LED transparent screen can not only play multimedia advertising content, but also basically does not hinder the line of sight ! The LED transparent screen and the gold jewelry store just like this.
Led transparent screen is not only in gold jewelry stores, but also in clothing stores, jewelry stores, hotpot stores, mobile phone stores, 등. if you have window glass, you can try led transparent screen. It can not only not affect the view of the store, but also play multimedia advertising, which can greatly improve the rate of entering the store!
일반적으로 말하면, for the major businesses and places, the LED transparent screen is very good. It can not only coordinate the store’s outdoor publicity activities and interior customers’ aesthetic needs, but also meet the advertising needs and further ehance te aesthetic quality of large shopping malls while ensuring the visual effect; While the glass guardrails on shopping malls and flyovers can maintain the original beauty, they can further explore the advertising value. Bank chains and government units can publicize anti fraud awareness and holiday information to the masses through transparent windows Regardless of the size of merchants, led transparent screen development can bring them new business opportunities and explore a new world.

Led transparent screen, we are not unfamiliar, since Zhang Yimou director uses “ice screen”, quickly let people know, so what is the relationship between LED transparent screen and ice screen? Where can led transparent screen be used? What should be paid attention to when purchasing? How much is the price of LED transparent screen? We will pay attention to these issues.
Led transparent screen is also called ice screen, transparent LED display screen, led glass screen and led window screen. It is a kind of LED display screen. Because the screen body is close to transparent, it is called transparent screen. The permeability rate generally varies from 50% to 95%. We can see the characteristics of the LED transparent screen and know where it can be used.
Led transparent screen features 1: high transparency, transparency is an important feature ofLED transparent display. The transparency is between 50-95%. The perspective effect keeps the function of light perspective. Far away, it can hardly see the presence of LED transparent screen, which makes the lighting of glass curtain wall and window unaffected. Of course, the higher the transparency, the more expensive the money, it is better to choose the right one according to our actual situation, and do not catch up with it Please be the most expensive.
Led transparent screen features 2: light and thin, led transparent screen is different from the conventional LED display screen, which takes up small space and light weight, and the screen body thickness is only about 10 mm. The LED transparent screen is usually used in combination with glass, which hardly occupies space, and is not as heavy as the conventional LED display. The weight of LED transparent screen is only 14kg/ ㎡, and there is no big problem when it is installed on the glass wall.
Led transparent screen features 3: easy to install. Because the LED transparent screen is relatively light and thin, it is very simple and convenient to install. It does not need to build steel frame structure, which can save a lot of costs and quickly install, and can greatly save material cost and labor cost. So, deeply sought after!
Led transparent screen features 4: good maintenance, led transparent screen is relatively simple, maintenance is also simple and convenient, simple problems can be dealt with by themselves, avoid the factory to deal with the problem on the spot, can save time and human costs.
Led transparent screen features 5: energy saving and environmental protection, the power consumption of LED transparent screen is much smaller than that of conventional LED display screen, less than 280w/ ㎡, and no additional air conditioning is needed to heat dissipation. 게다가, the power consumption of glass curtain wall is not large, which can offset power loss completely with advertising benefits. It is an extension for traditional LED display screen.
Through the above five characteristics of LED transparent screen, we probably know where the LED transparent screen can be used. We will make a simple explanation one by one.
Glass curtain wall of building, building is generally mainly glass curtain wall, which should be beautiful and light-emitting. Led transparent screen has little influence on lighting and beauty. It can be perfectly compatible with glass curtain wall. Video advertisement is broadcast on glass curtain wall. The effect is very shocking! 그러므로, many buildings begin to install led transparent screen!
2. in jewelry stores, the first thing led transparent screen is used is jewelry store. The environment of jewelry store is tall. The shop window should display products and can not block the passers-by to see the situation in the shop. So when the LED transparent screen appears, the owner of jewelry shop has a good eye. Now, the more used is gold jewelry shop, Shaanxi Province Xi’an China Gold flagship store uses LED transparent screen, and nearby friends can go and see the effect.
3. in the performance center, led transparent screen fire and Korea Winter Olympics and Beijing directed by Zhang Yimou for 8 minutes, the LED transparent screen on the field shows the beauty of technology, so that the world knows that the transparent screen is produced in China. We also know that the original led transparent screen can be used in this way. Since then, the LED transparent screen is also used in the performance center, performance stage and other places, and the effect is very excellent!
4. shopping center and shopping center are also a very high-grade place. Advertising should also be paid attention to. In the atrium of the mall, lifting a LED transparent screen will make your brand and your advertisement attractive?
5. the science and Technology Museum, led transparent screen has a high sense of science and technology. There are certainly many solutions in the science and technology museum full of sense of science and technology.
6. at airport terminal, led transparent screen can not only be used as information display, but also as advertising medium. In airport wharf, 호텔, 술집, KTV and other places with visual requirements, led transparent screen is no doubt the best choice.
Led transparent screen is very good in permeability, and it has quickly replenished short boards where the conventional LED display can not be extended. It shows its light in the LED display world! It plays an important role in the fields of urban lighting, glass curtain wall, shopping mall decoration, shop decoration, 등., and has attracted more and more attention and favor from more and more merchants! I believe that the use of LED transparent screen will be expanded more and more in the future Show!
As we all know, the traditional LED display screen is mainly used for outdoor advertising. In recent years, the regulatory authorities are increasingly strict in the supervision of outdoor advertising, which requires a lot of projects, which is very cumbersome and troublesome. 이때, the LED transparent screen can make up for this short board. 그만큼 transparent LED screendoes not need to be approved! Because it is used in combination with glass, it is generally used indoors!
Led transparent screen has the characteristics of high permeability, but more space, good display effect and so on, which can make up for the shortcomings of traditional LED display screen. It can also spread well under the premise of not affecting the beauty. It is deeply sought after by businesses. With the acceleration of urban construction, glass curtain wall, which is a kind of atmospheric grade, is becoming more and more popular. With the development of technology and application, it is becoming more and more popular Commercial display, high-tech field, and even digital dance art are the market of LED transparent screen.
In recent years, the digital sign industry represented by retail has expanded rapidly. Led transparent screen plays an important role in the fields of commercial retail window, interior decoration and building facade, which has brought great changes to new retail. Users can display the categories of products, key products and promotion information in the retail stores through LED large screen, so as to facilitate consumers to purchase their favorite goods more quickly, promote consumption demand and improve the shopping conversion rate of stores. Gold jewelry stores are the first to use LED transparent screens. The decoration of gold jewelry stores is relatively tall and needs to display advertisements, but it can’t affect the beauty. When LED transparent screens appear, they quickly become popular. Now walking on the street, you can see the beautiful images of LED transparent screens in the windows of many gold jewelry stores! Engineers from Shenzhen’s old led transparent screen manufacturers said, In the next two years, led transparent screen may usher in an explosion period! Led transparent screen has a very good use scene, in addition to the window of physical stores, can also be used on the glass curtain wall of the building, used in the airport wharf, exhibition hall and other places, where there is glass can be used, making the glass instantly become a billboard, which may also be a small change in the advertising industry!
The emergence of new retail will promote the development of commercial display market, at the same time, it will also create a certain incremental market for LED display. Led transparent screen with a new application form, leading technology development and close to the public demand design concept also makes it rise rapidly in a short time, a new blue ocean market rudiment has appeared.
There is no savior in the world, only to save themselves. If traditional retail wants to change the predicament, it can only use new retail, optimize itself by digital means, reduce costs and increase turnover. LED transparent screen is just one of the small media, and the key is Internet plus thinking to get out of a new sky. When the new retail business is in the ascendant, we should seize the time to adjust ourselves and be a little faster than our friends. Maybe we can reach the other side of success first!
Full color LED screens can be seen everywhere in the stadiums. How to choose the full-color LED display screen in stadiums? Here are some tips for you today.
1. Screen type
As we know, there are two kinds of full-color LED displays, indoor and outdoor. The two kinds of displays are quite different. The use scenarios are different. The full-color LED displays are different, and the prices are naturally different. 그러므로, we should first determine whether we are using them indoors or outdoors.
&2. Protective performance
Outdoor LED full-color displayhas been strengthened in terms of waterproof, heat dissipation and safety. Outdoor venues should use outdoor full-color LED display instead of indoor ones. 게다가, considering environmental factors, such as plateau, alpine and humid areas, targeted solutions should be taken, and it is not allowed to eat fresh food all over the world.
3. 명도
Outdoor venues have higher requirements on the brightness of full-color LED display screen. According to the viewing distance, the specification of full-color LED display screen with appropriate brightness should be selected reasonably. It should be noted that the larger the brightness value is, the more appropriate it is. For the LED screen, the brightness, specific illumination, energy-saving effect needs to be considered comprehensively. A full-color LED display screen product with high energy efficiency design is selected to ensure the safety, stability and service life.
4. Assembly mode
There are three common assembly methods of full-color LED display screen: hanging on the wall, falling on the ground and embedded in the wall. The location of the venue determines the assembly mode of the full-color LED display screen. According to the actual situation, the appropriate assembly method is adopted. Due to the long service life and complex structure of the full-color LED display screen, the maintenance window should not be cut off for the sake of beauty Mouth.
5. 시청 거리
When selecting full-color LED display screen, in addition to the use scene, it is also very important to see the viewing distance. In outdoor stadiums, it is necessary to consider the users who watch at medium and long intervals, and choose the display screen with larger point distance. P6 and P8 are two common types of outdoor stadiums, while indoor ones are different, with higher viewing intensity and closer viewing distance, P4 and P5 are more suitable.
6. Visual angle
For the stadium audience, due to the different seat positions and the same screen, the viewing angle of each audience is more and more scattered. The selection of LED screen with wide viewing angle can ensure that each audience has a good viewing experience. We must pay attention to this point when making the scheme, so as to give the audience good visual enjoyment.
7. 재생률
The refresh rate is an important indicator to measure the advantages and disadvantages of full-color LED display. The higher the refresh rate is, the better the stability of the displayed picture will be. The selection of a high refresh rate display screen can ensure the fluent connectivity of the live pictures of the event. The human eye will have a more warm and natural impression and a better experience. A full-color LED display screen has a variety of specifications with different refresh rates, which can be selected according to the actual situation.
When selecting the full-color LED display screen for stadiums and stadiums, the above seven factors can be considered comprehensively. 일반적으로, large-scale full-color LED display screen manufacturers will provide appropriate solutions, including the product model, specification and price. 게다가, it should be emphasized that no matter which scene or display screen is decided by considering the price factor alone, it must be comprehensive in many aspects It’s wise to make a decision again! 예를 들어, we should consider the strength of the manufacturer, the industry experience of the manufacturer, the number of cases done, 애프터 서비스, product quality assurance, and then consider the price. Most of the time, the price and quality are directly proportional to the after-sales service! Must not ignore the quality and after-sales for low price, otherwise endless trouble! Stadium full-color LED display selection tips to everyone here, if you have other questions, welcome to consult us.
요즘에는, for many people, led transparent screen is no stranger. It is widely used in all walks of life and is gradually popularized. What is the prospect of LED transparent screen? Will it be eliminated? Let’s talk about this topic today.
&According to the person in charge of the LED display screen factory, a well-known led transparent screen manufacturer in Shenzhen, the prospect of LED transparent screen is very broad, and it is the sunrise period now! ~ 안에 2017, led transparent screen has appeared in the eyes of the world, but it was still tepid at that time, and there are only a fewmanufacturers of transparent LED screens.
2017 is an important year for China to vigorously promote the construction of smart city. The development concept of “innovation, coordination, 녹색, open and sharing” continues to deepen. Concepts such as big data, Internet +, and Internet of things endow smart city with new connotations. 동시에, the construction of new city image emerges as the times require. More and more LED transparent display products appear in all corners of the new city Led transparent screens exist in industrial complexes, shopping malls, 4S shops, window windows and other places with glass. In building lighting engineering, the glass screens needed may be replaced by LED transparent screens, which will be more widely used. Take glass curtain wall as an example, many buildings now prefer the application of glass walls for lighting, saving building materials and environmental protection, and the LED transparent screen is the only one With its light weight, no steel frame structure, simple installation and maintenance, good permeability and other characteristics, the screen can be described as a perfect combination with glass curtain wall. Its application in glass curtain wall not only meets the requirements of the building itself for glass wall, but also adds a special aesthetic feeling to urban buildings because of its fashion, beauty, generosity, modern sense and scientific and technological atmosphere Good light transmission performance, led transparent screen wall will not affect the lighting of the building when it is not working, so its architectural practicability, display practicality, ornamental are greatly in line with the development requirements of the current city image. In short, it will not affect the lighting and beauty, but also play the role of advertising and information display. The future of LED transparent screen can be said to be limitless!
&게다가, with the development of smart city, some traditional advertising styles are becoming out of date. Fashionable and technologically advanced LED transparent screen is rapidly becoming the focus of many advertisers in the image of the new city. In the advertising application of smart city, led transparent screen shows a great market application trend. From national conditions to policies, and then to the dynamics of enterprises, all these signs seem to indicate that the LED transparent screen market is on the eve of a big explosion. It is expected that in the next three to five years, the LED transparent screen market may usher in a period of K-SPEED growth!
Looking at the LED transparent screen market, there are only a few large enterprises that can realize customization. Facing the market demand, the old led transparent screen manufacturer LED display screen factory feels more responsible. According to incomplete statistics, the orders of LED transparent screen factory are rising steadily, and there are many related cases, and the technology accumulation and industry experience are slow Accumulation, for the future of the industry to lay a good foundation, more competitive!
Led full-color display driver chip is an important part of the display screen. Different driving methods of LED chip can obtain different display effect of video screen image. 그러므로, the advantages and disadvantages of driver chip play an important role in the display effect offull-color LED display screen.
&1. LED driver chips are classified into the following two types: they are more commonly used in low-end LED panel production, and the commonly used general-purpose chip is 74HC595, which has the functions of 8-bit latch, serial parallel shift memory and tri state output.
Each channel can output 35 ma current (not constant current).
Special chip: a feature of special chip is to supply constant current source. As LED is a current characteristic device, its brightness changes with the change of current size, not with the change of voltage at its two ends. The constant current source can ensure the stable driving of LED and eliminate the flashing phenomenon of LED.
The maximum output current of the mainstream constant current source chip is about 90 ma. Constant current is the basic characteristic of special chip, and it is also the basis to get high image quality. The maximum constant current output of each channel at the same time (i.e. the maximum constant output current) is more meaningful for the display screen, because under white balance condition, each channel is requested to output constant current at the same time.
Current output error: there are two kinds of current output error: one is the inter bit current error, that is, the error between the outputs of the same chip; the other is the inter chip current error, that is, the output current error between different chips. Current output error is a key parameter, which has great influence on the uniformity of full-color display screen. The larger the error is, the worse the uniformity of the display screen is, and it is difficult to make the screen reach white balance. 현재, the bit to bit error of mainstream constant current source chip is generally within + 60%, and the chip to chip current error is within ± 15%. &There are two specifications of constant current source: 8-channel constant source and 16 channel constant source. Now 16 bit source is the mainstream. The advantage is that the size of LED driver chip is small, which is convenient for LED driver board (PCB) wiring, and it is more favorable for LED driver board with small point spacing.
Data shift clock: the data shift clock determines the transmission speed of display data, and is the key index affecting the update rate of display screen. As a large-scale display device, the display refresh rate should be above 85 Hz to ensure a stable picture (no scanning flicker). High data shift clock is the basis of high refresh rate screen. 현재, the shift clock frequency of mainstream constant current driver chips is generally above 15 MHz.
Full color LED display is one of the main windows to show this clue at present. It can not only review the past, present the present, but also look forward to the future.LED display gradually replaces sand table, ceiling, information wall and lighting. LED display is widely used in the Planning Museum to depict a clearer city dream.
Characteristics of display screen in urban science and Technology Planning Museum
가장 먼저, there is a unique structure. The Planning Museum is a closed indoor place with limited space. Due to the limitation of power supply, pipeline, fire protection and other conditions, the reasonable installation of each display screen needs corresponding structure to meet our expectations. 예를 들어, the cube LED screen requires us to accurately calculate the site.
Secondly, the display screen of the Planning Museum is a product requiring low brightness and high gray. Conventional LED display screen generally has high brightness, which is widely used in bright environment. 하지만, because the Planning Museum is in a closed indoor weak light environment, the best brightness is not greater than 800nit. Under this brightness, the conventional display screen will lose gray scale, skip frame, color gradient, uneven color, color deviation and so on. We have specially designed low brightness and high gray products for the display screen of the Planning Museum, which ensures that the display screen still has 14 levels of gray effect under the brightness of only 400 nit.
마지막으로, the integrated display control center. The planning hall is composed of multiple scenes, and all scenes need to be centralized in a control center, which requires a highly integrated control system to control all display screen products and lighting and audio equipment in the venue. So as to ensure that the display screen material replacement is simple. With integrated control center, the equipment maintenance is convenient, and the control system software is set once, which is permanent and effective.
The display screen in the Planning Museum is the essence of the city dream, and it is an art integrating the soul of the city. This artwork is changeable, delicate and unique.
Scene requirements for display screen of Planning Museum
Each city has its own unique cultural environment and scenery with local characteristics, which should be considered in the design of Urban Planning Museum.
In the coastal city planning hall, we integrated theP3.91 LED display screenwith the venue design to create a scene with sea scenery characteristics. The Planning Museum in coastal cities, with a 20 meter long, 120 ° viewing angle wide-angle curved screen, with ceiling and floor decoration, and other sensory equipment, makes people feel like the beach, watching the tide rise and fall, and deduce the magnificence of the sea indoors.
In the mountain city planning Museum, the local cultural landscape is integrated to create a scene with mountain customs. The Planning Museum in the city is connected with the ceiling and the ground with a 12 meter high folding display screen. The sky, the mountain, the foot of the mountain and the river valley are arranged in layers. With other sensory equipment, people can watch the moon rise and fall in Mingchuan, and feel the mountains and valleys in the museum.
&The display screen is not only used for display, but also integrated into the design of Planning Museum, such as floor, wall, ceiling, 등. This test is the comprehensive ability of the display manufacturer’s products. Our transparent LED display series, stage performance series, fixed display series, small spacing LED display series, also have sky screen display series. Different series are suitable for different scenes.
Design principle of display screen in science and Technology Planning Museum
1. Pixel density design
The distance between pixels on the screen is usually 0.1 mm. Because the distance below 0.1 mm exceeds the limit of retinal resolution, it can not be distinguished no matter how close you look, so it is regarded as a whole visually. The corresponding pixel density is about 300 ppi.
&The effective visual distance of LED display screen in the Planning Museum is generally 2m-16m. In order to make the viewer have the best visual effect, it is necessary to select the display point spacing according to the equivalent retinal distance. If the average display distance is 9 미터, the LED display screen with spacing of P3 can be selected to meet the display requirements in the Planning Museum. If the visual distance is 5 미터, p1.667 LED display screen can be selected to meet the display requirements.
The calculation formula is as follows:
1. Silence
The Planning Museum is located in a closed space, which requires high noise control. The traditional LCD and DLP splicing are equipped with cooling fan, which generates buzz while cooling. LED display does not need cooling fan for heat dissipation, and the power supply is equipped with fan free silent power supply. Redundant power configuration ensures that the effective load of the power supply is less than 60%, thus ensuring a quiet environment in the Planning Museum.
2. Consistency of super large splicing
Compared with the traditional LCD and DLP splicing, LED display unit module splicing will not appear black frame, which can achieve super large display panel splicing. 동시에, LED display can ensure that the brightness and chroma of the modules are consistent to achieve the best display effect of the whole screen. In terms of viewing angle, the left and right and up and down view angles of LED display are as high as 120 도, which can completely cover all corners of the interior of the Planning Museum.
3. Lightweight design
In the planning hall and other indoor places, the space is quite limited. In order to make more efficient use of space, the lightweight design of display screen is particularly important. The LED display screen can be installed in any space of 100 mm, which can only be installed in the wall of the museum.
4. System architecture
&There will be multiple displays in the Planning Museum. We have designed an integrated control for the LED display control center. Only one computer can control multiple displays at the same time. 동시에, the video processor integrated into the system can access all kinds of image input signals, and timely and accurately put the video picture information on the corresponding display screen.
Led transparent screen has been seen everywhere around us. It plays an important role in advertising and marketing, product promotion, popular science lectures, 등. in actual use, the clarity may be reduced. 오늘, we will give you the five factors that affect the clarity of LED transparent screen, and suggest collecting them.
1. Whether the source is HD. If the source is not HD, the clarity of the playback effect is not high. Let’s first exclude whether the source is HD, and then exclude the remaining factors. Of course, videos and pictures are the same. In principle, the higher the HD, the clearer the playback effect.
2. Whether the display screen supports full HD, there are many kinds of LED displays, including ordinary, high-definition and ultra-high-definition. If the screen is ordinary, there is no way to adjust, and only the high-definition module can be replaced.
3. The point spacing ofLED transparent video wall, the point spacing of LED transparent screen will affect the clarity. In principle, the smaller the point spacing is, the higher the definition is, the more delicate it is. 하지만, the price will be slightly higher. 그러므로, when selecting the LED transparent screen, we should select the module with appropriate point spacing according to our own needs and budget. Before choosing, we should understand that the point spacing will affect the clarity.
4. The combination of LED transparent screen and video processor, LED video processor can use advanced algorithm to modify the signal with poor image quality, perform a series of processing such as de interlacing, edge sharpening, motion compensation, 등., to enhance the details of the image and improve the image quality. The image scaling algorithm of video processor is used to ensure that the clarity and gray level of the image are maintained to a large extent after the video image is scaled. 게다가, the transparent display screen also needs the video processor to have rich image adjustment options and adjustment effects to process the brightness, contrast and gray of the image to ensure the soft and clear screen output.
5. Improve the gray level of the LED transparent screen. The gray level refers to the brightness level that can be distinguished from the dark to the bright in the single primary color brightness of the LED transparent screen. The higher the gray level of the LED transparent screen is, the richer the color is, the more bright the color will be; 반대로, the display color is single and the change is simple. The improvement of gray level can greatly enhance the color depth, which makes the display level of image color increase geometrically. The gray control level of LED is 14bit ~ 16bit, which makes the high-end display products achieve the advanced level of image level resolution details and display effect. With the development of hardware technology, led gray level will continue to develop to higher control accuracy.
&There are five factors that affect the clarity of LED transparent screen. When we choose, we can choose according to the actual demand and budget. In principle, the clearer the screen is, the more expensive it will be. No matter what, there is no mistake in shopping around. I hope it can help you. If you like, please continue to pay attention to it.
led life determines the life of display screen, but it is not to say that led life is equal to display life. 디스플레이 화면이 항상 풀로드 상태에서 작동하지 않기 때문에, 디스플레이 화면의 수명은 6-10 비디오 프로그램을 재생하는 일반적인 조건에서는 LED보다 몇 배 더 오래 지속됩니다..
내부 요인에는 주변 구성 요소의 성능이 포함됩니다., LED 발광소자의 성능, 제품의 피로 방지 성능; the internal factors include the working environment of LED display screen and so on.
(1) influence of peripheral components
In addition to LED light-emitting devices, LED advertising displayalso uses many other peripheral components, 회로 기판 포함, 플라스틱 껍질, 스위칭 전원 공급 장치, 커넥터, 사례, 등. if any component fails, the life of the display screen may be reduced. 그러므로, the long life of the display screen is determined by the life of the key component with short life. 예를 들어, ~ 주도의, 스위칭 전원 공급 장치 및 금속 쉘은 8년 표준에 따라 선택됩니다., 회로 기판의 보호 프로세스 성능은 다음 작업만 지원할 수 있습니다. 3 연령. 후에 3 연령, 부식으로 인해 손상될 것입니다., 그래서 우리는 3년 된 디스플레이 화면만 구할 수 있어요.
(2) the influence of LED light-emitting device performance
LED light-emitting device is the key part of display screen, and also related to life. LED용, 주요 지표는 다음과 같습니다: 감쇠 특성, 수증기 투과성 특성, 자외선 방지 성능. If the LED display manufacturer fails to evaluate the performance of LED devices, 디스플레이 화면에 적용됩니다, 이는 많은 품질 사고로 이어질 것이며 LED 디스플레이 화면의 수명에 심각한 영향을 미칠 것입니다..
(3) the influence of anti fatigue performance of the product
The anti fatigue performance of LED display depends on the production process. 불량삼방지처리 공정으로 생산된 모듈의 내피로 성능을 보장하기 어렵다.. 온도와 습도가 변할 때, 회로 기판의 보호 표면에 균열이 나타납니다., 보호 성능 저하로 이어짐.
그러므로, LED 디스플레이 화면의 생산 공정도 디스플레이 수명을 결정하는 핵심 요소입니다.. 디스플레이 화면 생산과 관련된 생산 공정에는 다음이 포함됩니다.: 부품 보관 및 전처리 과정, 용광로 용접 공정, 세 가지 예방 치료 과정, 방수 밀봉 공정, 등. 프로세스의 효율성은 재료 선택 및 비율과 관련이 있습니다., 매개변수 제어 및 작업자 품질. For most LED display manufacturers, 경험의 축적은 매우 중요합니다. 다년간의 경험을 가진 공장은 생산 공정을 제어하는 데 더 효과적입니다..
(4) impact of working environment
Due to different uses, the working conditions of display screen are very different. 환경적인 관점에서, 실내 온도차가 적다, 비의 영향 없이, snow and ultraviolet; the outdoor temperature difference can reach 70 도, 플러스 바람, 태양과 비. 열악한 환경은 디스플레이 화면의 노화를 악화시킵니다., 작업 환경은 디스플레이 화면의 수명에 영향을 미치는 중요한 요소입니다..
The life of LED display screen is determined by many factors, but the end of life caused by many factors can be continuously extended by replacing parts (such as switching power supply). The LED is not likely to be replaced in large quantities. 그러므로, once the life of LED is over, it means the life of display screen will be terminated.
작은 전류 조건에서 LED가 작동하는 경우, LED의 수명이 길어질 수 있습니다.. 그러므로, 이 브랜드의 LED를 사용한 디스플레이 화면의 수명은 약 50000 시간.
How to make LED life longer? In general, we can start from two aspects of device manufacturing and device application. In terms of device manufacturing, LED life can be prolonged by choosing epitaxial materials, increasing chip area and reducing current density, equalizing current density, reducing thermal resistance, selecting packaging materials with excellent performance and strong UV resistance.
From the aspect of device application, it can extend the service life of led by taking heat dissipation as a central work from module design to engineering implementation and even future system maintenance; reducing the working current of LED; correctly configuring led to make all primary color LED decay synchronously.
Whether the LED lamp is stable, the quality is good or not and the heat dissipation of the lamp body is very important. 현재, the heat dissipation of high brightness LED full-color screen is usually natural heat dissipation, and the effect is not ideal. If the heat dissipation is not ideal, the life of the lamp itself will also be affected.
