The first is high luminous efficiency: the light effect of LED electronic display can be said to be an important indicator of energy saving effect. At present, China needs to strengthen the light effect. To achieve high light efficiency, it is necessary to solve related problems from all links in the industrial chain. Technical issues, how to achieve high light efficiency? This article will specifically discuss the technical issues to be solved in several links such as extension, chip, package, and lamps.
1. Improve internal quantum efficiency and external quantum efficiency.
2. Improve package light extraction efficiency and lower junction temperature.
3. Improve the light extraction efficiency of the luminaire.
Secondly, from the perspective of high color rendering: led electronic display light color quality, including color temperature, color rendering, light color fidelity, light color naturalness, hue recognition, visual comfort and so on. Here we are only discussing the issue of color temperature and color rendering. Producing a high color rendering led display light source will lose more light efficiency, so take care of these two factors in design. Of course, to improve high color rendering, you must also consider the RGB three primary color combination to achieve. Here are my three methods:
1. Multi-primary phosphors.
2. RGB multi-chip combination.
3. Phosphor plus chip.
Again, from the perspective of high reliability: it mainly includes indicators such as failure rate and longevity. However, there are different understandings and explanations in the application. High reliability refers to the ability of a product to perform a specified function under specified conditions and within a specified time. The led failure category mainly has serious failures and parameter failures. Lifetime is a characterization of product reliability. : Generally refers to the statistical average. For a large number of components, the life of the LED device is the meaning of this description. However, factors affecting the reliability of led display products include chip manufacturing, packaging, thermal resistance, and heat dissipation. Since this is said, I hope that enterprises will make two requirements on the basis of performing total quality control on led display products:
1. Reduce failure rate.
2. Extend the loss of time.
Finally, in reducing the cost of products: At present, many consumers feel that the price is too high when they buy the led display. Therefore, many entrepreneurs of led display have also taken corresponding measures to reduce costs in addition to mass production. , mainly methods and ways to take measures to reduce costs. Mainly in the epitaxial chip, packaging, drive, heat dissipation and other aspects to reduce costs, thereby fundamentally solving the cost of LED display products. Specifically speaking from the following four aspects:
1. The method of reducing the cost of the epitaxial chip link.
2. The method of reducing costs in the packaging process.
3. The method of reducing the cost of the lighting link.
4. Reduction of other supporting costs
