LED display technology

The LED display technology to the problem

China is the world's LED display Windows manufacturer, currently 80% of the world's LED display from China. Mention display, everybody is not new. Today the streets, malls, station, the airport can be seen everywhere.T8 LED Tube dab4d58ck With the popularization and application of the market further, the LED display technology is also increasingly mature, but there are four major technical problems with a lot of manufacturers.

First 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 gentle show color sexual problems, 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:

Many different schemes;

RGB multichip combination;

Phosphor add chip.

Next is the 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? LED Bulb A19 This paper will specific vying for the extension, chip, encapsulation, lamps and lanterns several links to solve technical problems are discussed.

Improve the efficiency and the quantum in quantum efficiency;

Improve the encapsulation efficiency and reduce the light and temperature;

Improve the efficiency of the lamps take light.

Again, on the high reliable from: mainly including the failure rate, the life of the index. But in the application is different understanding and the elaboration, 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, and life is the reliability of the product characterization 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 do two requirements:

Reduce failure rate;

Extend the failure time 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 lower the cost of method, way, mainly in the extension of the chip,wholesale office furniture desk neize225dw sealing, drive, heat dissipation, etc to reduce cost, thus fundamentally solve display the cost of the product. Concrete from the following four aspects to reduce costs.
