What does the three high and one low of the LED display refer to

　　"Three highs and one low" refers to the high color, high light, high reliability and low cost in the LED display technology.

　　How to achieve low cost and allow the quality of the LED display to reach the "three highs". This requires a series of measures on all aspects of the LED display industry chain. Such as the use of new technologies, new structures, new processes, new materials, etc. As an emerging industry now, the LED display is very important to technology and is also the core issue in the overall process.

　　From the perspective of high color rendering: LED display has a lot of light color quality, including color temperature, color rendering, light color preservation, light color naturalness, color tone recognition, visual comfort, etc. Here we only discuss solving the problem of color and color rendering. Making high -color full -color full -color LED display light sources will lose more light effects, so take care of these factors when designing. Of course, in order to improve high coloring, it is necessary to consider the RGB triple -based color combination to achieve. I also have three ways here:

　　1. Multi -base fluorescent powder.

　　2.RGB multi -chip combination.

　　3. Fluorescent powder and chip.

　　The second is highlighting effect: For the light effect of the LED electronic display, it can be said to be an important indicator of energy saving effects. At present, my country needs to be strengthened in the light effect effect. Technical issues, so how to achieve high light efficiency?

　　1. Improve internal quantum efficiency and external quantum efficiency.

　　2. Improve the efficiency of packaging out of light and reduce knot temperature.

　　3. Improve the lighting efficiency of the lamp.
