LED displays have unique natural advantages in creative display. Led creative display screen has a broad development space, and the development potential of LED creative display is huge.

Nowadays, when it comes to creative display, people are no longer unfamiliar. In recent years, more and more creative LED displays appear in our life. In the major led exhibitions, we can also see a variety of LED creative screens, such as speaker screen, Mitsubishi rotating screen, diamond screen, spherical screen, etc.

There are not many customers who have just entered the special-shaped LED display industry. Many customers think that the price difference is so big for the same type of special-shaped LED display screen. Why is the price of P3 and p2.5 much more expensive than that of P4 for the same size of ball screen, which is unacceptable?

Let’s discuss the factors that affect the quoted price of molded LED displays.

How to calculate the price of special-shaped LED display?

First of all, the space between the creative screen material points, the smaller the material point spacing, the higher the price, of course, the better the display effect. Hei tauira, the price of material P3 (the so-called P3 refers to the spacing between LED lights and lamps is 3 mm. The smaller the screen point spacing in the same area, the higher the density of LED lights in the special-shaped LED display screen) is obviously much more expensive than P4 and P5

Tuarua, it is necessary to do waterproof treatment. Ko te tikanga, the design scheme of indoor irregular LED display screen has met the daily waterproof requirements, but outdoor LED must undergo special waterproof treatment, and the price of waterproof treatment is not cheap, which is also an important factor affecting the price.

I taua wa ano, the difficulty of creative display screen customization and whether the program needs to re open mold design. If manufacturers have never produced this type of product, they often need to design production plans from scratch, which increases production costs. I taua wa ano, the difficulty of the scheme customization and the complexity of the project are also factors that can not be ignored in the quotation. Hei tauira, a P2 spherical screen costs twice or more than P3 or P4.

Ka mutu, a customized number of special-shaped LED display. The unit price of products with small material and customized quantity is often very high, and even some manufacturers are not willing to accept this type of order. Because of such an order, manufacturers usually need to arrange production. Because the quantity is small, but the complexity of the project is the same general scheme, manufacturers can not get economies of scale, and their own costs are high, so manufacturers must provide high price quotations.

Ko te tikanga, there are more, such as whether the computer, installation costs, te whiwhi kaari, sending card, box, business tax, freight and so on.

&Technological innovation is an eternal topic in the LED display industry. Only by constantly introducing new technologies and new products can we ensure the smooth completion of the industrial upgrading.

Nowadays, with the vigorous development of outdoor advertising, outdoor advertising screen is no longer easy to achieve significant results. Ko te mutunga, more and more media companies have begun to favor large-scale display carriers, forcing pedestrians around to stare at it.

In recent years, outdoor LED media operators have emerged, but at the same time, we also see that the level of outdoor LED screen media operators is uneven. In order to maintain the daily operation of the media, regardless of the quality and content of advertising, it has a negative impact on the media image. No reira, in order to further realize the healthy development of different media and industries, and establish a good brand image, Media and long-term sustainable development and continuous innovation are crucial. Through in-depth interviews, experts have also confirmed this view: continuous innovation and strengthening the quality of media are very important. Some outdoor media have launched screen interaction and QR code scanning, etc. New technology can attract consumers to participate in the process of brand communication, so as to promote the integration of media advertising value.

Tuarua, audience identification helps to change the advertising effect

Outdoor LED display can effectively improve the audience’s cognition and attitude towards the brand. In the field of outdoor media, respondents are more inclined to think that the brand of outdoor LED screen advertising is a powerful big brand, and also a big brand in various industries. I taua wa ano, LED display advertising is also very helpful to improve the brand and product impression. 76.1% of the audience thought that outdoor LED display advertising had a greater impact on brand and product impression. Product advertising efforts and the formation of a good brand image will play a decisive role in the purchase of consumers. After contacting with outdoor LED display advertising, the audience’s behavior will be affected by the advertising, and then produce behavioral intention. Among them, nearly 20% of them will actively search for relevant information on the Internet, 6.7% will directly go to the store for consultation, 24.7% will try to buy products, a 37.3% will pass on or actively discuss the relevant product information to others to form a secondary communication.

Third, high arrival rate and wide audience coverage

LED display screen with its large screen area, eye-catching, strong visual impact, wide visual range and color characteristics, has a good visual distance and super clear picture, plus the unique space advantage, so that led display media has attracted the attention of urban people. The survey shows that the average arrival rate of outdoor LED display media is 61.8%, the average weekly arrival frequency of business district is 3.8 times, and the average monthly arrival rate is 79.3%. 30% of the audience actively pay attention to the outdoor LED display media, and the average single eye stay time of the audience is 15.1 seconds. LED display has a relatively stable and repeatedly contacted audience, which is conducive to the effective dissemination and understanding of LED display media information.

Fourth, the unique space value of core business district

Outdoor LED display media are mainly distributed in landmark buildings and part-time jobs in core cities, central business districts, traffic arteries and densely populated areas. With the development of urbanization, these places have become the main places of the city, and the mainstream people are engaged in business activities, leisure, entertainment, catering and shopping. No reira, it has the characteristics of scarcity, and the core has become a form of media and marketing value and quality. According to the survey, the average arrival rate of outdoor LED display media is 61.8%, and the average weekly arrival frequency is 3.8 times, and the average arrival rate is 79.3%. 30% of the audience actively pay attention to the outdoor LED display media, and the average single viewing rate of the audience is 15.1 seconds. LED display has a relatively stable and repeatedly contacted audience, which is conducive to the effective dissemination and understanding of LED display media information

I tenei ra, let’s introduce the stage LED display. Whenever we see a stage like TV or a concert, we will be shocked by their stage effect. Then you must also want to know how the torture gorgeous effect is made. Let’s look down:

the design of large screen that usually appears on the stage now can be divided into three types.
the first kind: according to the stage frame, the LED screen is the main body, and the lighting position is reserved around the unit screen. The stage is also relatively common. Hei tauira, te “come on good man” Party of Oriental satellite TV has set up a stage frame of overall depth. The screen is hung on such a stage frame in an orderly manner, and a head shaking computer light is hung between the screen and the screen. It’s the screen that leads the disappearance of the stage into the distance, which makes the depth of field of the whole picture longer and produces a strong perspective effect. I tua atu, there is so much space for lighting hanging and playing on the edge. The whole stage has good atmosphere and dynamic, which also expresses the theme of the party. Heoi ano, in this way, the stage structure will be relatively simple and not vivid.

the second kind: only take the LED screen as the whole stage design, the large screen design as the background, the side screen, the space and time in the scene all let the LED large screen complete, the actors do no physical performance. A lot of places use such scenes as and Of course, it has its advantages, that is, it saves time and money. A picture can explain all the things that should be explained in the plot. A piece of video can give the whole program a sense of form. In particular, some local TV stations have bought a large screen, which saves a lot of dance expenses.

but doing so will inevitably result in the conceptualization of the whole stage. I tenei ra, we will perform the rural scene, change the background to a picture of a rural house, tomorrow we will show a picture of a high-rise building, a dynamic music and a dynamic abstract pattern. Without the characteristics of the stage, it also makes the stage appear very thin and has no three-dimensional sense. The audience can see the planes at a slight angle, perhaps with some reflection. The best stage form of

of course, the style of stage LED display is various, each era will have different forms of stage performance, but led display screen has undoubtedly become a trend of the times, can be seen everywhere in every corner of life, and is indispensable on the stage. Application of science and technology is not the only means, the key is what means we can use to achieve the ideal stage effect.designed for you a distinctive, colorful, special effects stage LED display screen factory has always been the original intention and confidence.

LED display factory p4.81 outdoor small space LED display screen on 100 square meters stage rental successfully settled in Incheon, South Korea. Speaking of South Korea, what do you think of first? Food, handsome men, beautiful women Now, the success of Huaze p4.81 stage rental screen will take you back to the memory buried in your mind – you from the stars.

the once popular TV series was taken from Incheon — Incheon University and Incheon Wide Area Municipal Museum. The p4.81 stage rental screen is a scene under direct sunlight, which is mainly used for large-scale stage performance with the theme of “great journey, new challenge, 70 years of happiness and 20 tau”, which is divided into three screens. The biggest feature of the rental screen is that it moves frequently. No reira, with the pace of renting the screen, we can appreciate the different beauty of South Korea, such as the places where “you from the stars” once walked, as well as various tourist attractions

p4.81 belongs to outdoor small space series products, with low brightness and low gray, fine quality, tere tāmata tiketike. Hei tauira:

1, low gray and low brightness: in the case of low gray and brightness, the picture is still clear and visible, and the color restoration is high.

2 2, unique design: the box with scale, can rotate 15 tohu, according to a certain radian can be assembled into round screen, arc screen, etc., when tile can be made, vertical can be made into hoisting, fixed screen and led rental screen.

3, box compatible: the box size is 500 * 500mm / 500 * 1000mm, which can be used with p2.98, p3.91, p4.81, p5.95, p6.25 indoor and outdoor boxes. High quality material selection: p4.81 outdoor surface mounted full-color screen adopts smd2727 lamp beads, with good waterproof and heat dissipation performance, wide viewing angle and high brightness.

it is precisely because p4.81 outdoor small space LED display has so many advantages, so since our company developed this product last year, customers have applied the product in the fields of stage rental, fixed LED display, LED floor tile screen, etc., and has been promoted in various regions, and has been recognized in the market.

Full color LED display screen “in front of the screen and behind the screen” cooperate with each other.

Only with the assistance and cooperation of the supporting equipment in front of and behind the screen, can the indoor screen and small space display effect be more perfect.

Yang Lichang said: “with the LED display screen moving from outdoor to indoor, compared with the outdoor large LED screen, the audience’s identification rate of indoor LED screen is improved, and the requirements for display color and display effect are also higher. To meet these higher requirements, we must rely on the supporting equipment behind the scenes – lamp beads, driving IC, pūtukatuka ataata, pūnaha whakahaere, etc., to do the corresponding cooperation.”

“Tuarua, the rise of small spacing leads to direct competition with traditional indoor splicing large screens such as LCD and DLP rear projection. Heoi ano, at present, small spacing is at a disadvantage in terms of technology – point spacing (LCD LCD dot spacing can achieve p0.6) or cost. Although small spacing seamless splicing, tino rereke, wide color gamut display, energy saving and other aspects can occupy one However, in the future, small space LED display must be more excellent if we want to continue to occupy the market share of indoor large screen splicing with LCD LCD and DLP rear projection, and these all need the assistance and cooperation of supporting equipment, so as to achieve a more perfect display effect of indoor LED display screen and small space LED display screen. ”

tino rereke, high gray and high refresh rate are the direction of future efforts.
full-color LED display is a hot topic in the current industry. Why small spacing LED display is sought after by the industry and consumers is obviously because the display effect of small spacing is better than that of traditional indoor splicing large screen, such as LCD. In order to achieve the display effect of “low brightness, high gray and high brush” o small pitch LED display screen, the driving IC undoubtedly plays the most important role.

in this regard, Yang Lichang told reporters: “compared with the lamp beads which account for 70% of the total cost of the LED display screen, the cost of driving IC is somewhat insignificant, but its role is decisive: tere tāmata tiketike, tino rereke, high gray and other display effects must rely on the cooperation of the driving IC to complete.” At the early stage of the market entry of

small spacing LED display screen, the topic most talked about was how to solve the seven major problems of small spacing LED display screen: Ghost, first line dark line, low gray color deviation, low gray uneven, gradient dark line, high contrast interference, and elimination of cross phenomenon caused by LED open circuit. With the rapid progress of technology in recent years, these problems have been solved perfectly with the technical cooperation and cooperation of the manufacturers of driving IC and control system. As a driver IC manufacturer, our next task is to further improve the contrast, gray level and refresh rate of LED display, and we should not sacrifice its gray level while improving the contrast. This is a challenge for us, and we need to work together with manufacturers such as lamp beads and control systems. ” Yang added.

I tenei wa, LED display can be seen everywhere in many large and medium-sized cities, towns and public institutions. With the popularity of outdoor LED display, it has been integrated into our life. Outdoor full color LED display can not only be used as the carrier of advertising video, but also an external platform for government agencies to release government information and city propaganda films.

full color LED display screen can spread information, beautify the image of the city and improve the grade of the city, so it is strongly supported by the government. In response to the call of China’s vigorous development of information society, according to the development of wireless communication in China, more and more asynchronous LED control cards are used for outdoor LED display. Compared with typical wireless LED control cards, 2G / 3G / 4G is used to control the LED screen wirelessly, including the program to be uploaded and the related settings of LED screen. The reason why outdoor LED display screen will favor wireless LED control card is mainly because wireless LED display control card has the following four advantages:

1, simple operation and convenient information release The LED display screen is connected with the server through wireless communication. It can be used to publish advertising content and control the LED screen by simply setting up the relevant software or the cloud platform built by the server, which is convenient and fast.

2, cluster control, time-saving and labor-saving.
outdoor LED display generally has two outstanding characteristics: large number and wide distribution. Each card of wireless LED control card corresponds to an IP number, and a single IP address or multiple IP addresses can be controlled through cloud platform, which greatly simplifies the work of later program release; Through 2G / 3G / 4G wireless communication, as long as there is a signal, no matter how far the distance is and how wide the distribution, you can remote control the LED display. The most outstanding advantage of wireless LED control card is that it is especially suitable for the government departments such as meteorological bureau and Public Security Bureau. If you need to insert emergency notice information, you just need to select the LED screen to be played by software, and upload the emergency notice information immediately. This is very fast and convenient.

4, whakaurunga ngawari, high cost performance ratio,
wireless LED display control card set the relevant adjustment screen parameter keys, through the burning program adaptive LED display, convenient and easy to adjust the parameters of a LED display screen, do not need to connect the computer such a troublesome debugging process; It saves a series of costs such as computer or receiving card, as well as the labor cost of later management. The cost performance of wireless LED display control card is very high.

For some people, from the beginning of LED display screen design to the final decision, there is a part of the link related to the LED display project budget. If this part of the budget goes wrong, it will have a great impact on the follow-up work. Shenzhen LED display screen factory teaches you how to reach the goal in six steps, from novice to proficient in LED display engineering business budget.

takahanga 1: calculate the engineering quantity of LED display screen. If you have a good idea, you can be prepared.
first needs to ask the engineering party for the engineering list, or compile the bill of quantities according to the field survey. If the bill of quantities is provided in the project bidding documents, the quantities shall be checked before the tender price is calculated. If the bill of quantities is not provided in the bid documents, the total quantities must be calculated according to the drawings. If the bidding document has provisions on the calculation method of the project, the calculation shall be conducted according to the specified method.
only when the calculation is accurate and you know what you know, you can be prepared and you will not make mistakes.
takahanga 2: determine the unit price and calculate the total price.
in the tender offer, after calculating the quantities of each part and item, it is necessary to determine the unit price of each divisional and subdivisional project, and fill in the quotation according to the format of the bill of quantities in the bidding documents. Ko te tikanga, the unit price and total price are filled in according to the contents of the quantities of the sub items and the name of the project. When calculating the unit price, all the cost items constituting the divisional and subdivisional works shall be included.
the cost of labor, materials and machinery should be calculated according to the consumption of labor, materials and machinery of divisional and subdivisional works and their corresponding market prices. Ko te tikanga, the contractor should establish its own standard price database and calculate the bidding price of the project. When the unit price database is used to bid for a specific project, it is necessary to review, evaluate and adjust the selected unit price, which means that it conforms to the actual situation of the bidding project and reflects the change of market price.
in each stage of tender price preparation, the tender price is generally calculated in the form of table.
takahanga 3: determine the engineering cost of subcontracting LED display screen. The subcontracting cost of
is an important part of the bidding price. Sometimes, a considerable part of the bidding price of the general contractor comes from the subcontracting engineering cost. No reira, when preparing the tender price, it is necessary to have a verified price to measure the price of the subcontractor, be familiar with the scope of the subcontract project, and evaluate the ability of the subcontractor.

The popularity of LED display rental market is becoming more and more popular. I tua atu, many large-scale LED manufacturers are competing for this market, and the competition among renters is becoming increasingly fierce. Shenzhen LED display screen manufacturer LED display factory will change the traditional mode and open up “Internet plus” new products.

in recent years, the state has implemented a thrifty policy, and the cost budget of large-scale activities has been significantly reduced. As can be seen from the sharp “shrinkage” of LED display screen in the Spring Festival Gala in recent two years, this has also brought a great impact to the LED display rental market. As the LED rental market “Red Sea” began to appear, the fierce price war also spread rapidly.

has experienced wave after wave of price attacks from Nga kaihanga whakaatu LED. Enterprises that make a living by renting display screens have also begun a fierce competition. The rental price of the same product is no longer stable, and the payment cycle of customers is gradually lengthening. Price competition among peers is more common. I taua wa ano, the number of LED rental screen manufacturers has further increased, and the distributors and agents that led display manufacturers are looking for have joined the wave of seizing the local market. The increasingly transparent price of LED display products has forced a considerable part of rental manufacturers’ profits to decline sharply, and the scenery is no longer good.

Shenzhen LED display factory Technology Co., Ltd. has been adhering to the creative and diversified design concept in product design. Over the years, we have focused on the research and development, production and sales of LED display screen products. The product series include: LED display, LED advertising screen, led rental screen, LED floor tile screen, led sky screen, small spacing LED display screen, LED advertising machine, etc. at present, the series of products have covered many fields, such as indoor and outdoor advertising, cultural plaza, commercial buildings, hotera, whare hokohoko, stadiums, papamuri atamira, etc. We are committed to providing smart city solutions and opening up internet plus new products.

In recent years, te price of LED display screen is becoming more and more popular, and its application is penetrating into the commercial and civil fields. The market needs to rely on continuous large-scale driving growth. LED display manufacturers have always insisted on quality first, casting brand with quality, and making a market with quality.

only good quality can guarantee effective service. It is often said that “safety has no trivial matter”. In fact, for the LED display screen industry, safety is no small matter, and small things are important things. In recent years, due to various reasons, the safety accidents of display screen occur frequently, which causes the industry to think deeply. Whenever the LED display screen accident occurs, it is a warning to the LED display industry. Although we always say that the production technology of LED display industry has entered the mature stage, should we pay more attention to the basic product quality problems while improving the technology? If every time we go to the industrial product quality inspection, we are repeatedly found out that the LED display products are unqualified, and the accidents are one after another, and the LED display industry has repeatedly made “headlines” due to negative reports, what is the face of led enterprises? 1. The spirit of contract: consolidate the brand with integrity.
in the process of made in China, created in China and made in China, the key first step is from made in China to created in China. The sign of China’s creation is the formation of a large number of localized independent brands, but at present, the ownership rate of China’s independent brands is only about 25%. For a long time, China’s manufacturing enterprises have a strong dependence on foreign technologies and patents, and have the thinking inertia of “bringing in” brand, which leads to the lack of energy for independent brand innovation and the habit of technology imitation. In order to solve the similar problems, on the one hand, we should encourage manufacturing enterprises to firmly establish the concept of independent brand; on the other hand, we should strive to overcome the demand side’s mentality of worshipping foreign countries. The premise of brand independence is to advocate the spirit of contract.

conclusion: making products depends on quality. To win by quality, let the service more in place, good quality to convince consumers. Product innovation is not the most important, the basic product quality to control, do not pit consumers, do not smear the LED display industry. Also led display industry a clear sky.

If the LED display screen is in high temperature for a long time without heat dissipation, it is easy to cause a fire. Shenzhen LED display manufacturer introduces how to prevent it in the bud. The following are the examples of accidents caused by high temperature of LED display screen. According to the introduction of the LED display screen in the Baiyun Airport, a fire broke out on the outside of the Baiyun Airport at 10:00 a.m. on February 27, 2013, a LED display screen on the outside of the Baiyun Airport broke out at 10:00 a.m., and a fire broke out on the outside of the airport. I tenei wa, no casualties have been reported.

on December 16, 2011, a fire broke out in Xizhimen shopping center in Beijing, which was caused by improper construction of LED screen. At the end of the same month, LED display screen of traffic building in Yueqing City, Zhejiang Province also suddenly caught fire. Fortunately, no casualties were caused in the two accidents.

at the 2010 Guangzhou International Lighting Festival, a fire broke out on the main LED screen hanging outside the new Guangzhou Library and facing Huacheng square, and the fire was rapidly rising. Although firefighters arrived to put out the fire within minutes, the whole screen had been destroyed and the outer wall of the new library was also blackened.

these cases all show that high temperature is easy to cause fire accidents, so the heat dissipation of LED display screen has become the top priority, which needs to be prevented before it happens. Otherwise, the consequences will be unimaginable. How can the LED display screen heat dissipation. The heat exchange area between the heating electronic parts and the cold air, and the temperature difference between the heating electronic parts and the cold air directly affect the heat dissipation effect. The design of LED air duct involves the size of the air duct. In the design of ventilation duct, the straight pipe should be used to convey air as far as possible, and sharp turning and bending pipe should be avoided. Sudden expansion or contraction of ventilation ducts shall be avoided. The expansion angle should not exceed 20O, and the contracted cone angle should not be greater than 60o. Ventilation ducts shall be sealed as far as possible, and all laps shall be in the direction of flow.
2, LED display heat dissipation
LED display box design, there are several points to note:
1, air inlet should be set at the bottom of the box, but not too low, to avoid dirt and water into the LED display box installed on the ground. A 6032 2 2. The exhaust hole should be set near the upper side of the box. A 6032 3. The air should circulate from the bottom to the top of the box, and special air inlet or exhaust hole should be used. A 6032 4. Cooling air should be allowed to flow through the heated electronic parts, and the short circuit of air flow should be prevented at the same time.
