The LED transparent screen is 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.

window led screen

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, və s. 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!

Standard grounding method for LED display?

high definition led walll (4)

Some customers often use the wrong grounding method to ground the LED display screen. The common ones are: 1. The lower end of the column of outdoor column structure is connected with the earth, so it is not necessary to do the grounding of the display screen; 2. It is considered that the power supply is locked on the box, and the boxes are connected with each other with lock locks and structures, so the structure grounding means that the power supply is also grounded.

high definition led walll (4)

There are misunderstandings in these two kinds of practices. Our column is connected with the foundation bolt of the foundation, and the anchor bolt is embedded in the concrete. The resistance of the concrete is in the range of 100-500 Ω. If the grounding resistance is too high, the leakage current will not be discharged timely or there will be residual. The surface of our box is sprayed with paint, and the paint is a poor conductor of electricity, which will lead to poor contact or increase of grounding resistance of the box connection, which may cause the interference of the screen signal by electric spark. With the passage of time, the box or structure surface will appear oxidation and corrosion, and the screws and other fasteners will gradually loosen with the change of temperature difference. It will cause the effect of structure grounding to be weakened or even completely invalid. It is a potential safety hazard. It leads to leakage current electric shock, chip interference damage and other safety accidents.

What should be the standard grounding? As shown in the figure below: the power input terminal has three wiring terminals, which are the live wire terminal, the zero line terminal and the grounding terminal. The correct grounding method is to use the special yellow and green double color wire to connect and lock all the power ground wire terminals in series, and then lead out to connect to the ground terminal. &If there is no grounding terminal on the site, it can be connected to the iron water pipe or iron sewer pipe buried and in good contact with the earth. In order to ensure good contact, the terminal block should be welded on such natural grounding body, and then the ground wire should be tightly locked on the terminal block, and no binding connection is allowed. Lakin, gas and other flammable and explosive pipes shall not be used. Or lay grounding body on site. The grounding body can adopt angle steel or steel pipe, which can be buried in the ground horizontally or vertically as a simple grounding point. The grounding point should be located in a remote place to prevent pedestrians or vehicles from damaging the grounding body.

When we are grounded, the grounding resistance must be less than 4 ohm to ensure the timely discharge of leakage current. It should be noted that when the lightning protection grounding terminal discharges the lightning current, due to the diffusion of the earth current, the ground potential will rise in a short time. If the LED video wall is grounded to the lightning protection grounding end, the ground potential is higher than that of the display screen, and the lightning current will be transmitted along the ground wire to the screen, causing equipment damage. Buna görə də, the protective grounding of LED display screen shall not be connected to the lightning protection grounding end, which must be more than 20 meters away from the lightning protection grounding end. Prevent the counterattack of ground potential. &Led grounding precautions summary: 1. Each power supply must be grounded from the grounding terminal and locked; 2. The grounding resistance shall not be greater than 4 Ω; 3. The ground wire shall be a dedicated conductor, and it is strictly prohibited to connect with the zero line; 4. No air switch or fuse shall be installed on the ground wire; 5. Ground wire and grounding terminal should be more than 20 away from lightning protection grounding terminal;

Where can led transparent screen be used for?

led advertising screens (1)

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. Buna görə də, we should first determine whether we are using them indoors or outdoors.

&2. Protective performance

Outdoor LED full-color display has been strengthened in terms of waterproof, heat dissipation and safety. Outdoor venues should use outdoor full-color LED display instead of indoor ones. Əlavə olaraq, 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. Parlaqlıq

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. Baxış məsafəsi

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. Yeniləmə dərəcəsi

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. Ümumiyyətlə, large-scale full-color LED display screen manufacturers will provide appropriate solutions, including the product model, specification and price. Əlavə olaraq, 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! Misal üçün, we should consider the strength of the manufacturer, the industry experience of the manufacturer, the number of cases done, after-sales service, 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!

2017 is an important year for China to vigorously promote the construction of smart city. The development concept ofinnovation, coordination, yaşıl, open and sharingcontinues to deepen. Concepts such as big data, Internet +, and Internet of things endow smart city with new connotations. Eyni vaxtda, 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, ticarət mərkəzləri, 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!

&Əlavə olaraq, 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.

LED full color display performance parameters driver chip classification.

led advertising screens (2)

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. Buna görə də, the advantages and disadvantages of driver chip play an important role in the display effect of full-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).

led advertising screens (2)

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 (yəni. 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. Hal hazırda, 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. Hal hazırda, the shift clock frequency of mainstream constant current driver chips is generally above 15 MHz.

Characteristics of display screen in urban science and Technology Planning Museum

First of all, 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. Misal üçün, the cube LED screen requires us to accurately calculate the site.

İkincisi, 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. Lakin, 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.

Nəhayət, 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 the P3.91 LED display screen with 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, və s. 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 metr, 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 metr, 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. Eyni vaxtda, 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 degrees, 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. Eyni vaxtda, 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.

Five factors affecting the clarity of LED transparent screen.

led advertising screens (5)

Led transparent screen has been seen everywhere around us. It plays an important role in advertising and marketing, product promotion, popular science lectures, və s. in actual use, the clarity may be reduced. Bu gün, we will give you the five factors that affect the clarity of LED transparent screen, and suggest collecting them.

led advertising screens (5)

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. Əlbəttə, 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 of LED transparent video wall, the point spacing of LED transparent screen will affect the clarity. In principle, the smaller the point spacing is, tərif bir o qədər yüksəkdir, the more delicate it is. Lakin, the price will be slightly higher. Buna görə də, 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, və s., 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. Əlavə olaraq, 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; on the contrary, 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.

 

What are the factors that affect the life of LED display.

led advertising screens (4)

led life determines the life of display screen, but it is not to say that led life is equal to display life. Because the display screen is not working at full load all the time, the life of the display screen should be 6-10 times longer than that of the LED under the normal condition of playing video programs.

The internal factors include the performance of peripheral components, the performance of LED light-emitting devices, the anti fatigue performance of products; 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 display also uses many other peripheral components, including circuit board, plastic shell, switching power supply, connector, case, və s. if any component fails, the life of the display screen may be reduced. Buna görə də, the long life of the display screen is determined by the life of the key component with short life. Misal üçün, rəhbərlik etmişdir, switching power supply and metal shell are selected according to the 8-year standard, while the protective process performance of the circuit board can only support its work for 3 illər. After 3 illər, it will be damaged due to corrosion, so we can only get a 3-year-old display screen.

(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. For LED, the main indicators are as follows: attenuation characteristics, water vapor permeability characteristics, anti ultraviolet performance. If the LED display manufacturer fails to evaluate the performance of LED devices, it will be applied to the display screen, which will lead to a large number of quality accidents and seriously affect the life of LED display screen.

(3) the influence of anti fatigue performance of the product

The anti fatigue performance of LED display depends on the production process. It is difficult to guarantee the anti fatigue performance of the module produced by the poor three prevention treatment process. When the temperature and humidity change, cracks will appear on the protection surface of the circuit board, leading to the decline of the protection performance.

Buna görə də, the production process of LED display screen is also the key factor to determine the display life. The production process involved in the production of display screen includes: storage and pretreatment process of components, furnace welding process, three prevention treatment process, waterproof sealing process, və s. The effectiveness of the process is related to material selection and proportioning, parameter control and operator quality. For most LED display manufacturers, the accumulation of experience is very important. A factory with many years of experience will be more effective in controlling the production process.

(4) impact of working environment

Due to different uses, the working conditions of display screen are very different. From the environmental point of view, the indoor temperature difference is small, without the influence of rain, snow and ultraviolet; the outdoor temperature difference can reach 70 degrees, plus wind, sun and rain. Harsh environment will aggravate the aging of display screen, and the working environment is an important factor affecting the life of display screen.

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. Buna görə də, once the life of LED is over, it means the life of display screen will be terminated.

When the LED works under the condition of small current, the life of the LED can be longer. Buna görə də, the lifetime of the display screen with this brand of LED can reach about 50000 saat.

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. Hal hazırda, 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.
