"Three high and one low" refers to the high color rendering, high luminous efficiency, high reliability and low cost in LED display technology.
How to achieve low cost and make LED display quality reach "three high". This requires taking a series of measures in each link of the LED display industry chain. Such as new technology, new structure, new process, new materials, etc. As an emerging industry, LED display technology is very important, and it is also the core issue in the overall process.
From the perspective of high color rendering: LED display screen has a lot of color quality, including color temperature, color rendering, color fidelity, color naturalness, color recognition, visual comfort, etc. At present, we only discuss how to solve the problems of color temperature and color rendering. The production of high color rendering full-color LED display light source will lose more light efficiency, so these two factors should be taken into account in the design. Of course, the combination of RGB three primary colors must be considered to improve the high color rendering. Here I have three methods:
1. Multi primary phosphor.
2. RGB multi chip combination.
3. Fluorescent powder plus chip.
Secondly, high luminous efficiency: the luminous efficiency of LED electronic display screen can be said to be an important indicator of energy-saving effect. At present, China still needs to strengthen its luminous efficiency. To truly achieve high luminous efficiency, we need to solve relevant technical problems from all aspects of the industrial chain. How to achieve high luminous efficiency?
1. Improve internal quantum efficiency and external quantum efficiency.
2. Improve the light output efficiency of the package and reduce the junction temperature.
3. Improve the light taking efficiency of lamps.
