LED display screens are becoming more and more widely used in life, and large-screen display technology has also improved. At present, LCD displays are highly valued for their excellent display effects, but the splicing technology in large-screen displays has not yet reached a seamless level. The small spacing of LEDs has successfully made up for this shortcoming and has successfully risen. In the period when LCD large-screen seamless splicing technology was mature, LED displays jumped up and occupied the large-screen display market.

The solution to the technical problems of LED display

First, high light efficiency: The light efficiency of LED displays can be said to be an important indicator of energy-saving effects. At present, my country's light efficiency needs to be strengthened. To truly achieve high light efficiency, it is necessary to solve related technologies from all aspects of the industrial chain. Question, then how to achieve high light efficiency? This paper will specifically strive for technical issues in several links such as epitaxy, chips, packaging, and lamps.

1. Improve the efficiency of internal quantum and external quantum.

2. Improve packaging efficiency and reduce junction temperature.

3. Improve lighting efficiency.

Secondly, from the perspective of high color rendering, LED displays have many light and color qualities, including color temperature, color rendering, light color fidelity, light color naturalness, hue recognition, and visual comfort. Here, we now only discuss solving the problem of color temperature and color rendering. The light source of high color rendering LED display will lose a lot of light effect, so these two factors must be considered in the design. Of course, in order to improve color rendering, the combination of RGB three primary colors must be considered. I also have three methods here

1. Multi-primary phosphors.

2. RGB multi-chip combination.

3. Phosphors and chips.

Third, from the perspective of high reliability: it mainly includes indicators such as failure rate and life. But there are different understandings and explanations in the application. High reliability refers to the ability of the product to complete the specified functions within the specified conditions and within the specified time. The types of LED faults mainly include serious faults and parameter faults. Service life is a characteristic value of product reliability. Generally refers to the statistical average. For a large number of components, the service life of light-emitting diode devices means this description. However, factors that affect the reliability of LED display products include chip manufacturing, packaging, thermal resistance, and heat dissipation. Now that this point is mentioned, it is hoped that enterprises will make two requirements on the basis of comprehensive quality control of light-emitting diode display products:

One is to reduce the failure rate.

2. Extend the failure time.

Finally, in terms of reducing product costs: At present, many consumers feel that the price is too high when buying led display screens, so they have also taken corresponding measures against these many led display screen manufacturers. In order to reduce costs, in addition to mass production , And mainly adopt technical measures to reduce costs. It is mainly to reduce the cost in terms of extending the chip, packaging, driving, heat dissipation, etc., so as to fundamentally solve the cost problem of LED display products. Especially from the following four aspects:

1. The method of extending the chip to reduce the cost.

2. Methods to reduce costs in the packaging process.

3. Methods to reduce the cost of lamps and lanterns.

4. Reduce other supporting costs.
