Recently, there was good news. The P2.5 full-color LED display produced by CREUVIEW and installed in Xi’an Chanba Ecological Park was completed. The expert’s acceptance was fully qualified and passed smoothly. The user is very satisfied and gave CREUVIEW’s high-definition LED display. It is highly recognized.

   Among them, not only our products are praised, but also the vigorous and dedicated work style of the engineers and technicians shocked the customers. The customer of this project has been hesitant in the procurement comparison process. The poster customer sent someone to visit the company’s production scale and strength and product quality before signing the procurement contract. This resulted in a very tight construction period. When I arrived, I rushed to the project site and worked overtime all night to install and debug, which was completed one day earlier than the scheduled construction period. The customer was impressed by CREUVIEW’s engineering services.

Effectively eliminate moiré, wide color temperature adjustment, low brightness and high gray effect, high refresh rate, non-reflective, ultra-high resolution, realistic color reproduction, seamless vision, nanosecond response speed, low power consumption, ultra-quiet And other advantages. Widely used in electric power, civil air defense, transportation, radio and television, public safety, conference rooms, water conservancy and water affairs, tobacco and other industries: indoor control rooms, large conference centers, security monitoring, production emergency command, large-scale performances, competitions, radio and television industry background walls , Commercial brand display, public information display, etc.

Full-color LED display 3D technology accelerates to seize the share of LCD screens

Judging from the market’s response in 2013, the application of high-definition indoor full-color LED display is mainly to replace indoor DLP, LCD, projection, etc. The application areas include conference video, security monitoring, command and dispatch center, etc. From the perspective of the entire indoor display industry, the sales of DLP, LCD, projection and small-pitch LED displays in 2013 were about 11 billion, and the indoor display market share in 2014 and 2015 could reach about 15 billion.

  To enter the civilian market, LED TVs need to make further breakthroughs in some technologies and applications. First of all, the problem of the display screen, the current display point of LCD TVs can achieve 0.58, even smaller and 0.4, 0.3. If LEDs are used instead, further breakthroughs in the upstream technology of the display LED industry chain are needed; secondly, application companies are required Further in-depth research and development will be carried out to combine the panel and the cabinet more effectively; in addition, can the combination of the PCB board and the LED panel be separated? If the LED TV fails, only a simple module replacement is required by the maintenance personnel. These are issues that application companies need to make further breakthroughs in the R&D process; again, further reduce prices and gain wider market acceptance. It is worth pointing out that the current comfort problem for direct viewing of LED TVs with human eyes has been solved, which is mainly manifested in the technical indicators of low brightness and high grayscale.

  However, it is worth mentioning that LED displays have made initial breakthroughs in naked-eye 3D display effects. In the future, full-color LED displays will truly achieve high-definition displays. At the same time, with naked-eye 3D high-tech functions, it will be LED indoor One direction of the display’s value-added. The naked eye 3D LED display not only brings shocking display effects to the audience, but also realizes a healthy and comfortable naked eye vision 3D feast. Just imagine, when the audience take off the shackles of traditional 3D glasses and easily enjoy movie theaters and commercial advertisements in public places, the naked-eye 3D LED display will become the focus of the audience.

Several major characteristics of the LED display market in the Year of the Ox

Price cut: helpless to continue. The price drop of LED display terminal products best reflects the helplessness of the industry. A company once said that the average price per square meter of LED full-color display products in 2009-2011 was 12,400, 12,000, and 10,700 respectively. , The average selling price in 2011 decreased by 13.71% compared to 2009. The company did not point out the price of its products in 2012 and 2013. In fact, according to the average selling price in the market, the price per square meter of LED full-color displays ranges from several thousand yuan. The price is publicly bid by the manufacturer. Depending on the material and process, taking outdoor P10 as an example, the price per square meter ranges from 4,000 to 10,000 yuan. If it is a wholesale indoor full-color display, the price is even lower. It can be seen that the continued decline in the price of LED display products in 2013 is a manifestation of industry competition, and this trend will continue.

   Second, run off, in 2013, the living environment of LED display companies is not optimistic. Especially for small and medium-sized enterprises that do not have scale advantages and product advantages, it is even more difficult to find a balance in the cracks. As the price of LED displays is becoming more and more transparent, and the payment cycle is getting longer and longer, the company doing project engineering has to deal with the entanglement of customers, but also take responsibility for the supplier. Therefore, once bad debts or product problems are discovered, it may be possible As a result, the entire enterprise cannot be turned around, and finally it has to go bankrupt. Big Horizons, Haobo, Vision Light, Everlight, Shifang, and other billion-dollar enterprises are also unable to escape bad luck, and the impact of their bankruptcy is huge, leaving behind a lot of debts. In the end, innocent employees and suppliers are injured. NS.

   Third, channels: continue to be hot. Channel competition has always been a must for LED lighting companies. However, in recent years, LED display manufacturers have also begun to be keen on expanding channels, mainly because display products have become more standardized and large-scale. Whoever can get the support of distributors across the country can cover the national market and expand its influence.

Fourth, expansion: non-stop. Some people say that the LED display industry market competition is so stimulating, how can anyone expand production? This statement is wrong. Not all companies are compressing their own business. On the contrary, the market downturn has eliminated some companies while also giving some companies opportunities. Chips have received many government preferential treatments or direct subsidies for their expansion. Some companies have also continued to expand their production due to industrial needs. The construction of industrial parks is ready for subsequent production. Of course, some manufacturers of wholesale display screens are also constantly expanding production. Although their profits are meager, their business seems to be getting bigger and bigger.

   Fifth, subdivision: a common practice. When the argument that the LED display market is saturated began to circulate in the industry, many visionary companies have begun to focus on emerging market segments. The competition of display screens in the conventional field depends on the strength and price of the enterprise, but the more segmented market depends on the technical ability of the enterprise. At present, the LED display industry has gradually opened up some new growth highlights, such as high-density and small-pitch LED displays, and thus put forward the concept of LED super TV; such as outdoor surface-mounted LED displays, which will be outdoor direct-plug displays The future replacement device of the screen.

   Sixth, integration: has become a trend. Integration includes horizontal integration and vertical integration. Enterprises can choose the way of integration according to their own development needs. Many companies separate marketing from the two major sectors of display and lighting at the same time, which is a kind of integration; Sanan Optoelectronics and National Star Optoelectronics, through equity participation or establishment of branch companies, spread their antennae throughout the upstream chip, midstream packaging and downstream application fields, which is also a kind of integration; Epistar in Taiwan, China, is using virtual vertical integration as a strategy to strengthen its export on the application side; more display companies are doing integration actions in the form of bundling or alliances with suppliers. In short, integration has become an unstoppable trend in the LED display industry, and it is also a direct contributor to the future market structure.

Do you know the six major directions for the future development of LED displays?

1.Development towards energy saving

LED (semiconductor light-emitting diode) itself is very energy-saving, its characteristics are: high luminous efficiency, long life, easy control, maintenance-free; it is a new generation of solid cold light source, light color is soft, colorful, colorful, low loss , Low energy consumption, is a green and environmentally friendly product. But when it is made into an LED display, the power consumption is not small. The working voltage of the LED is generally 3.2V, and the maximum working current is 0.02A, which means that the maximum power consumption is 0.06W. However, large LED screens are large screens, which require a lot of points. Take the outdoor P16 display as an example: there are 3906 dots per square meter, and one dot has three RGB lights, then the power consumption calculation formula for one square meter is 3906 (dots) × 3 (lights) × 0.02 (A) × 5(V)=1172W (maximum power consumption, calculated according to the entire screen), the outdoor screen is at least tens of square meters, or even hundreds of square meters, then the total power consumption is very large. Therefore, reducing the power consumption of the LED display and realizing real energy saving are definitely the most important development direction of the LED display.

Second, develop towards lightness

At present, the most manufactured product in the industry is the iron box screen. The light screen weighs more than 50 kilograms per square meter, plus the weight of the steel structure, and the overall weight is very heavy. Even if it is a small and medium-sized project of tens of square meters, the total weight must be in tons. In this way, many floors of buildings are difficult to withstand such heavy attachments, and the load-bearing balance of the building and the pressure of the foundation are not easy to accept. Therefore, lightness is also the development direction of large LED screens.

Third, develop in the direction of thin and transparent

The commonly used electronic products in our lives, TV sets are becoming thinner and thinner, many mobile phones also use ultra-thin as a product highlight, and computer monitors are also developing in a thinner direction. The product becomes thinner and the weight is correspondingly lighter, which makes it easier to transport and to assemble the display screen. Large LED screens must also keep up with the mainstream of the era of electronic products. Let’s talk about “permeable”. “Permeable” refers to both air and light. If the large LED screen is installed on the top of a high-rise building, then air permeability is very important. The greater the air permeability, the smaller the wind resistance, the stronger the wind resistance, and the greater the protection of the product. If the LED display is installed on the side of a high-rise building, then the product can transmit light and will not affect the indoor lighting. Otherwise, after the product is installed, it will become a dead wall, making the room as dark during the day as at night. In summary, light transmission is also the development direction of large LED screens.

Fourth, develop in the direction of patent protection

From the perspective of global LED patent status, as far as technology is concerned, LED has the characteristics of high technical bottleneck but low entry barrier. The initial investment amount is small and the capital threshold is not high. In order to maintain technological competitiveness and reduce the risk of technological spillover, patents are the best way to protect. The patent barrier is the main means for the first to enter manufacturers to avoid competition. Therefore, patents have become an important issue that cannot be avoided in the development process of the LED industry, but the entire industry has not paid much attention to it. After the start of the LED display industry, there was basically no adjustment and development, and it directly entered a stage of fierce competition. Everyone was busy fighting for the market and expanding the scale, and hardly spent much energy on product research and development, and had not considered knowledge. Property rights are protected, and some new technologies have not been applied for patents in time. As the industry gradually matures, regulates, and protects one’s intellectual property rights and intangible assets by applying for patents is also the inevitable development direction of the LED large screen industry.

Fifth, develop in the direction of fast and accurate splicing

This is mainly for the LED rental display. Lease is characterized by frequent disassembly and assembly to meet temporary needs, so the display cabinets must be able to be spliced ​​quickly and accurately. Just like an outdoor temporary concert, you need to rent a background display of about 50 square meters, and the decision to use a display may be installed two days before the concert. In view of this situation, if the products cannot be spliced ​​quickly and accurately, there will be no way to meet the requirements of the site. Even if it is a fixed installation, this requirement is also required, otherwise it will increase labor costs, affect the flatness of the large screen, and thus affect the display effect. Therefore, fast and accurate installation is also the development direction of LED display.

6.Development towards standardization

At the beginning of this century, huge market demand made large LED screen companies sprung up. Almost overnight, thousands of LED display companies appeared on this magical land in Shenzhen. At the beginning of the establishment of the new enterprise, there will be products to display and sell immediately. Independent research and development of new products has a large investment and a slow speed, so everyone is trying to take shortcuts, sloppy designs, and mutual plagiarism have become a common problem at this stage of the industry. It is not just that the products between companies have different dimensions, mounting holes, etc., even their internal products are also uneven. The mounting fixing plates, hole positions, and screw specifications of the same type of product are not universal. This pair of parts Procurement, material preparation, after-sales service, etc. cause great inconvenience. Therefore, the standardization of LED large-screen products is also an inevitable trend.

What is the viewing angle of a full-color LED display?

We know that televisions, computer screens and LCD screens all have viewing angles, and this statement also exists in the field of LED screens. What is the viewing angle of a full-color LED display? What factors does the viewing angle have to do with? With this question, let’s learn together:

1.Definition of viewing angle of full-color LED display

The viewing angle of a full-color LED display refers to the angle at which users can clearly observe all content on the screen from different directions. The viewing angle can also be understood as the maximum or minimum angle at which the screen can be seen clearly. And the viewing angle is a reference value. The viewing angle of the LED full-color display includes two indicators, horizontal and vertical.

For example, usually full-color LED display, the technical parameters have this description: Viewing angle: 140°/140°; refers to the maximum viewing angle of 140°, the maximum horizontal and vertical viewing angle is 140°, after more than 140 degrees , The viewing effect is poor or there are blind spots.

The horizontal viewing angle is based on the vertical normal of the full-color LED display (ie the vertical imaginary line in the middle of the LED display), and it can still be seen normally at a certain angle to the left or right of the normal. For displaying images, this angle range is the horizontal viewing angle of the LED full-color display; similarly, if the horizontal normal is taken as the standard, the vertical viewing angle is called the vertical viewing angle. Generally speaking, the viewing angle is based on the contrast change as a reference standard. When the viewing angle increases, the contrast of the displayed image seen at this position will decrease, and when the angle increases to a certain extent, the contrast decreases to 10:1, this angle is the maximum viewing angle of the full-color LED display.

2.Factors affecting the viewing angle of a full-color LED display

The larger the full-color LED screen can be seen by the audience, the better, so the larger the viewing angle, the better. However, the size of the viewing angle is mainly determined by the die packaging method, so we must carefully consider when packaging the die.

In addition, the viewing angle has a lot to do with the viewing angle and distance. At present, most LED display manufacturers have the same angle. If you customize the angle according to the actual situation, the cost will be very high. In addition, with the same chip, the greater the angle, the lower the brightness of the full-color LED screen.
