First of all, high light efficiency: for the led electronic display light efficiency can be said to be an important indicator of energy efficiency, the current effect of light in China has yet to be strengthened, to really do high light efficiency, from all aspects of the industry chain to solve the relevant Technical problems, then how to achieve high light efficiency? This article will be specific to the extension of the chip, packaging, lighting and other aspects to solve the technical problems to explore.
1. Improve internal quantum efficiency and external quantum efficiency.
2. Improve the efficiency of packaging light and reduce the junction temperature.
3. Improve the efficiency of light extraction lamps.
Followed by high color from the point of view: led electronic display a lot of light quality, including color temperature, color, light color fidelity, light color natural degree, color recognition, visual comfort and so on. Here we are currently discussing only solving the problem of color temperature and color. Making high color display led light source, will lose more light efficiency, so in the design to take care of these two factors. Of course, to improve the high color of the RGB must also consider the combination of three primary colors to achieve. Here I also have three ways:
1. Multi - color phosphor.
2. RGB multi-chip combination.
3. Phosphor plus chip.
Again from the highly reliable up: mainly including failure rate, life and other indicators. But in the application there are different understanding and elaboration. High reliability refers to the ability of the product to perform the specified function within the specified conditions and within the specified time. Led failure category are mainly serious failure and parameter failure. Life is the representation of product reliability. : Generally refers to the statistical average, for a large number of components, led device life is the use of this description of the meaning. But the impact of led display product reliability factors are chip manufacturing, packaging, thermal resistance, heat and so on. Since it comes to this, I hope the enterprise led display products in the implementation of comprehensive quality control on the basis of 2:00 requirements:
1. Reduce the failure rate.
2. Extend the time to wear failure.
Finally, in reducing the cost of the product: At present, many consumers in the purchase of led display when they feel the price is too high, so fight for a lot of this led display businessmen have taken the appropriate measures to reduce costs in addition to mass production , Mainly from the technical measures to reduce the cost of the way, the way. Mainly in the epitaxial chip, packaging, drive, heat and so reduce costs, thus fundamentally solve the cost of led display products. Specifically from the following four aspects:
1. Epitaxial chip link to reduce the cost of the method.
2. Packaging links to reduce costs.
3. Lighting links to reduce the cost of the method.
4. Other supporting costs are reduced
