LED technology for solving technical problems, it is learned. Many people think that simpler, in fact, the real LED display technology to solve the problem, the following four aspects is the most convincing, the most authoritative proof of practice.
The first is the high light efficiency: The light efficiency of the LED display can be said to be an important indicator of energy saving effect, at present, China's light effect needs to be strengthened, to really achieve high efficiency, from all aspects of the industrial chain to solve the related technology Question, then how to achieve high light efficiency?
1. Improve internal quantum efficiency and external quantum efficiency.
2. To improve the efficiency of the package and reduce the junction temperature.
3. Improve the lamp light extraction efficiency.
Second, from the perspective of high color rendering: LED display light color quality, including color temperature, color rendering, light color fidelity, light color nature, color tone recognition, visual comfort and so on. Here we only discuss to solve the color temperature and color problems. Production of high color rendering LED light source, will lose more light efficiency, so in the design to take care of these two factors. Of course, to improve the high color must also consider the RGB three primary colors to achieve.
1. Multi-color phosphors.
2.RGB multi-chip combination.
3. Phosphor plus chips.
Once again, from a high reliability: mainly including the failure rate, life expectancy and other indicators. However, there are different understandings and elaborations in the application. High reliability refers to the ability of the product to fulfill the specified functions under the specified conditions and within the stipulated time. LED failure categories mainly have serious failure and parameter failure. Lifetime is a measure of product reliability. : Generally refers to statistical averages, for a large number of components, the life of LED devices is the meaning of this description. However, the factors that affect the reliability of LED display products are chip manufacturing, packaging, thermal resistance, heat dissipation. Since it comes to this, I hope enterprises LED display products in the implementation of total quality control based on.
1. Reduce the failure rate.
2. To extend the wear and tear of failure time.
Finally, reduce the cost of the product: At present, many consumers feel that the price is too high when buying LED display, so many LED display entrepreneurs have also taken corresponding measures to reduce costs in addition to mass production , Mainly from the technical measures to reduce costs, ways. Mainly in the epitaxial chip, package, driver, cooling and other aspects to reduce costs, so as to fundamentally solve the cost of LED display products.
1. Epitaxial chip cost reduction methods.
2. Packaging methods to reduce costs.
3 ways to reduce costs of lighting.
4. Other supporting costs to reduce
The above is mainly from the high light efficiency, high color rendering, high reliability and low cost of the four major technical aspects of LED display to resolve the main technologies and take appropriate measures, in general, in general, in addition through the adoption of new technologies, new processes, New structure, new materials and other measures to achieve the LED display of high light efficiency, high color rendering, high reliability and low cost, from a deep point of view, should improve energy efficiency and light color quality LED display as a higher demand, thus Really for people to provide product demand!
