Mention LED display is no stranger to everyone, everywhere in the life. Usually, auditorium, airports, railway stations, shopping malls, square tower can be seen everywhere, should be widely. According to statistics, at present China LED display accounts for the largest international market. LED display excellent characteristics of its own with the push of the market, now has from the traditional heavy color is simple, smooth turn now light easy to install, is deep user's favorite. LED display industry rapidly occupy a position in the market, now has become the market to be bestowed favor on newly.
Stages: 1, the LED display utility model LED display has the environmental protection, high brightness, high-definition, high reliability features stand out gradually, and on a stage, the LED display market just meet the needs of people, but it can not meet the requirements on the LED display products, the quality is not pass. With the development of LED display, LED products now have a new breakthrough. At least than on a stage and improvement progress. Also developed a series of completely different from the traditional light source used products will be popular. LED display will be a larger, more wide development space. LED display is not only beautify the role, it made people more relevant work variable dribs and drabs of life. All vendors are to spell now is applied in design and technology research and development advantages.
Stage 2, LED display intelligent control: with the progress and development of LED display technology, the LED as the semiconductor industry, will also be on the high speed train, play their high controllable characteristics. From home to office buildings, from roads to the tunnel, from cars to walk, from indoor to outdoor, possess the LED display to intelligent control system will lead to higher levels of service to mankind. LED display industry will also by doing products, to design products, to provide the overall solution.
3, LED display alternative acceptance stage: due to the characteristics of the LED display products mainly reflects in high photosynthetic efficiency (small) energy consumption, long life characteristics of this phase is the early development of LED display, so in terms of price, in the customer seems to have certain ratio. Customer has an acceptable process, of course, customers in the use of habits and appearance of a transition and accept. Let the customer know the characteristics of the LED display products, choose a has the characteristics of longevity and power saving. Such customers easier to accept its relatively high prices, especially in the commercial situation, and now the customer is the price also is second, main is to pass on the quality. So manufacturers are now spell in quality price advantage.
How to solve the LED display four technical problems
To solve the problem of LED display technology, it is learned. A lot of people think is simple, actually really solve the problem of LED display technology, the following four aspects is one of the most authoritative most persuasive and proved.
First is the high photosynthetic efficiency: for photosynthetic efficiency energy saving effect can be said to be the important index of the LED display, at present our country on the lighting effect remains to be strengthened, to really to do high photosynthetic efficiency, must be considered in the industrial chain each link related technical problems, so how to realize the high photosynthetic efficiency?
1. The internal quantum efficiency and the external quantum efficiency.2. Improve the optical encapsulation efficiency and reduce the junction temperature.
3. Improve the efficiency of the take light of lamps and lanterns.
Secondly from high color rendering, LED display light quality a lot of color, including color temperature, color rendering, light color fidelity, light color natural, tonal recognition degrees, visual comfort, etc. Here we only discuss the solve the problem of color warm color rendering. Make high LED display light source color rendering and lose more lights, so to take care of in the design of these two factors. Of course to improve high must also consider the RGB trichromatic color combination.
Again from high reliability in terms of: mainly includes indicators such as failure rate and life. But there are different understanding and in the application. High reliability refers to the product under prescribed conditions and time, complete the required function. LED category main failure has serious failure and parameters. And life is the reliability of the product attribute value. : generally refers to the statistical average, for a large number of components, the life of LED device is to use the meaning of this description. The factors affecting the reliability of the LED display products have chip making, encapsulation, thermal resistance, heat dissipation, etc. Since when it comes to this, hope that enterprises in the implementation of total quality control of LED display products.
1. More gezer phosphors.
2. The RGB multichip combination.
3. The fluorescent powder and chips.
2. Prolonged wear failure.
Finally on the reduced cost of production: at present a lot of consumer are buying LED display all the time think the price is too high, so the struggle for the many LED display entrepreneurs take the corresponding measures, to reduce costs in addition to mass production, mainly from the technical measures to reduce the cost of ways and means. Mainly in the epitaxial chips, encapsulation, drive, the respect such as heat dissipation to reduce costs, so as to fundamentally solve the problem of the cost of the LED display products.
1. Epitaxial chips link cost reduction methods.
2. The packaging cost reduction methods.
3. The lamps and lanterns of link cost reduction methods.
4. Other supporting cost reduction
Above mainly from high photosynthetic efficiency, high color rendering, high reliability and low cost of four major technology to solve the main technology and take corresponding measures, LED display and, in general, in addition to the adoption of new technology, new technology, new structure, new materials and other measures to achieve high photosynthetic efficiency of LED display, high color rendering, high reliability and low cost, from a deeper level, ought to improve the quality of energy efficiency and light color as a higher requirement of the LED display, to provide products for people's real needs sex!
Introduction to LED display development prospects
From a global perspective, the led display industry of our country is the core technology and professional technology international companies. In the backdrop of the global energy conservation and emissions reduction, countries have launched the incandescent light bulb disable plan and LED promotion plan. Now but due to the national policy support, the LED display industry outlook is unlimited, will be a star of tomorrow in the future.
1, the deepening of product technology and product diversification
LED device technology and continuously improve performance, electronic technology rapid development and for the LED display product technology to deepen and improve the good foundation. At the same time LED display in all fields of social life has been widely used, the development of semiconductor lighting industry more LED display industry bring good opportunity, therefore, the LED display market development prospects. Deepen the technical connotation, rich product system, product diversification, highlight the advantages of the leading product is the important trend of the LED display industry in chengdu in sichuan province.
2, normal product standardization and application products in specific areas of specialization
Propaganda of the standards implementation and promotion, will promote the development of the standardization of LED display products. Conventional LED display products, standardization of display device and control system will be more widely adopted, the integration of LED display products occupied the main position in industry, standardization of LED display products the specialization of production and technical service market will be more obvious. In professional applications, LED display products to meet the needs of professional applications, will continue to improve professional level, combined with the application requirements of professional LED display products will expand to form of new products and new applications, such as designs city-lighting project of large LED display, LED display of the venue, the traffic in the field of LED display, etc.
3, industry within the rational division of labor and the formation of new industry pattern.
