Solution of technical problems of light emitting diode display.outdoor p3.91

　　First, highlight efficiency: The optical efficiency of the LED display can be said to be an important indicator of energy -saving effects. At present, my country needs to be strengthened in terms of light efficiency. To truly achieve high light efficiency, to solve related technologies from all aspects of the industrial chain. Question, so how to achieve highlight efficiency? This thesis will specifically strive for technical problems in several links such as extension, chips, packaging, lamps, etc.

　　1. Improve the efficiency of internal and external quantum.

　　2. Improve packaging efficiency and reduce knot temperature.

　　3. Improve lighting efficiency.

　　Secondly, from the perspective of high color rendering, the light color quality of the LED display includes 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. The light source of making high -toned LED monitors will lose a lot of light effects, so these two factors must be considered when designing. Of course, in order to improve color rendering, the combination of RGB triple color must be considered. I also have three ways here

　　First, multi -base fluorescent powder.

　　2.RGB multi -chip combination.

　　Third, fluorescent powder and chip.

　　Third, from the perspective of high reliability: it mainly includes indicators such as failure efficiency, life span. But there are different understandings and explanations in the application. High reliability refers to the ability to complete the prescribed function within the prescribed conditions and prescribed time. The category of luminous diodes mainly includes severe faults and parameter failures. Life life is the explanation value of product reliability. Generally refers to statistics average. For a large number of components, the service life of light -emitting diode equipment means this description. However, the factors that affect the reliability of the display of the light -emitting diode include chip manufacturing, packaging, thermal resistance, and heat dissipation. Now that this is mentioned, it is hoped that the enterprise will make two requirements on the basis of comprehensive quality control of the displayed product display products of the luminous diodes:

　　The first is to reduce the efficiency.

　　Second, extend the failure time.

　　In the end, the cost of reducing product costs: At present, many consumers feel that the price is too high when buying an LED display, so it has also taken corresponding measures for this many LED display manufacturers. , Also mainly adoptedTechnical measures to reduce costs. It is mainly to reduce costs in extending chips, packaging, driving, heat dissipation, etc., thereby fundamentally solving the cost of LED display products. Especially from the following four aspects:
