The main technical problems to solve the LED display some of the measures

The LED display as now new industry, the technology is very important, also is the key problem in the whole process, so this paper will discuss the main technical problems in need of solution, boils down to "3 tall one low", namely high photosynthetic efficiency, high color rendering, high reliability and low cost of the technical problems and achieve low cost its essence and technical problems. Of course these technical problems still need to solve in the LED display industry chain on each link took a series of measures. If use new technology, new structures and new technology, new material, etc. And in this paper the technical route and sighed take direction, hope that through this article to led industry entrepreneurs can in the innovation of the product to help.
Mainly from the "3 tall one low" namely high photosynthetic efficiency, high color rendering, high reliability and low cost for:
First is high photosynthetic efficiency: for the LED display efficiency can say is an important index energy saving effect, at present our country efficacy in effect remains to be strengthening, to really to do high photosynthetic efficiency, from industrial chain each link on solving related technical problems, so how to achieve high photosynthetic efficiency? This paper will specific vying for the extension, chip, encapsulation, lamps and lanterns several links to solve technical problems are discussed.
1. Raise the efficiency and the quantum in quantum efficiency.
2. Improve the encapsulation efficiency and reduce the light and temperature.
3. Improve the efficiency of the lamps take light.
Second from high show color sex to see: the led display light color quality many, including color temperature, color rendering, light color fidelity, light color naturalness, tonal recognition degrees, visual comfort, etc. Here we currently only discuss solutions to color mild show color sex. To make high color rendering the led display light source, will lose more lights, so in the design to take care of the two factors. Of course to improve high show color sex must also be considered RGB three colors to realize the combination. This way I also third kind of method:
1. Many different schemes.
2. RGB multichip combination.
3. Phosphor add chip.
Again, on the high reliable from: mainly including the failure rate, the life of the index. But in the application is different understanding and described. High reliability refers to products under prescribed conditions and within the time required, complete the required function ability. Led the major categories have serious failure failure and parameter failure. But life is the reliability of the product characterization of value. : generally refers to a statistical average, for large components is concerned, led the life of the device is the meaning of this description. But the impact of the LED display products factors of reliability have chip manufacturing, packaging, thermal resistance, heat dissipation, etc. Now that said this, hope the enterprise to the led display products in the implementation of the comprehensive quality control, and on the basis of 2 point requirements:
1. Reduce failure rate.
2. Failure time extended loss.
The last in the lower product cost: at present a lot of consumer is buying the led display time think the price is too high, so a lot of this dispute led display entrepreneurs also took the corresponding measures, to reduce costs in addition to the mass production, mainly from the technical measures to be taken to reduce the cost method and way. Mainly in the extension of the chip, sealing, drive, heat dissipation, etc to reduce cost, thus fundamentally solve the led display the cost of the product. Concrete from the following four aspects about:
1. The extension of the chip link cost reduction methods.
2. Encapsulation link cost reduction methods.
3. Lamps link cost reduction methods.
4. Other supporting cost reduction
Above is mainly from high photosynthetic efficiency, high color rendering, high reliability and low cost four technology to solve the led display of the main technical and adopt corresponding measures, total and overall, except through the new technology, new technology, new structures and new materials and other measures realize LED display high photosynthetic efficiency, high color rendering, high reliability and low cost outside, from deep view, should will improve energy efficiency and light color quality as the requirement of the led display, and really provide people with the needs of the products.
