Ralink display resolution for you, how to solve the problem of LED electronic display technology, is divided into four most is as follows:
A, high photosynthetic efficiency,
LED electronic display screen, belongs to lighting energy saving effect of the more important indicators, is now on the lighting effect remains to be strengthened in our country, to really to do high photosynthetic efficiency, from the industrial chain each link must solve related technical problems, so how to realize the high photosynthetic efficiency?
1. The internal quantum efficiency and the external quantum efficiency.
2. Improve the optical encapsulation efficiency and reduce the junction temperature.
3. Improve the efficiency of the take light of lamps and lanterns.
Second, high color rendering
There are many types of LED electronic display light quality, respectively, color temperature, color rendering, light color fidelity, light color natural, tonal recognition degrees, visual comfort, etc. Here we only discuss the solve the problem of color warm color rendering. Make high LED display light source color rendering and lose more lights, so to take care of in the design of these two factors. Of course to improve high must also consider the RGB trichromatic color combination.
1. More gezer phosphors.
2. The RGB multichip combination.
3. The fluorescent powder and chips.
Third, high reliability
Mainly includes indicators such as failure rate and life. But there are different understanding and in the application. High reliability refers to the product under prescribed conditions and time, complete the required function. LED category main failure has serious failure and parameters. And life is the reliability of the product attribute value. : generally refers to the statistical average, for a large number of components, the life of LED device is to use the meaning of this description. The factors affecting the reliability of the LED display products have chip making, encapsulation, thermal resistance, heat dissipation, etc. Since when it comes to this, hope that enterprises in the implementation of total quality control of LED display products.
1. Reduce the failure rate.
2. Prolonged wear failure.
Four, to reduce the product cost
At present a lot of consumer are buying LED display all the time think the price is too high, so on the many LED display manufacturers have adopted corresponding measures, to reduce the cost in addition to mass production, mainly from the technical measures to reduce the cost of ways and means. Mainly in the epitaxial chips, encapsulation, drive, the respect such as heat dissipation to reduce costs, so as to fundamentally solve the problem of the cost of the LED display products.
1. Epitaxial chips link cost reduction methods.
2. The packaging cost reduction methods.
3. The lamps and lanterns of link cost reduction methods.
4. Other supporting cost reduction
conclusion
From the above mainly from high photosynthetic efficiency, high color rendering, high reliability and low cost four technology to solve the LED display the main technology and take corresponding measures, in general, in addition to the adoption of new technology, new technology, new structure, new materials and other measures to achieve high photosynthetic efficiency of LED display, high color rendering, high reliability and low cost, from a deeper level, ought to improve the quality of energy efficiency and light color as a higher requirement of the LED display, to provide products for people's real needs sex!
