LED display can reduce costs through “three highs and one low”

Of course, solving these technical problems also requires a series of measures in all aspects of the LED display industry chain. Such as the use of new technologies, new structures, new processes, new materials. In this article, I mainly talk about the technical route and its direction. I hope that this article can explain the innovation of LED industry entrepreneurs in products.

The following is mainly from "three high and one low", that is, high luminous efficiency, high color rendering, high reliability and low cost:

High light efficiency

The light effect of LED display can be said to be an important indicator of energy saving effect. At present, China needs to strengthen the light effect effect. To truly achieve high light efficiency, it is necessary to solve related technical problems from all links of the industrial chain, then how to achieve high light How effective? This article will specifically discuss the technical issues to be solved in several links such as extension, chip, package, and lamps.

1. Improve internal quantum efficiency and external quantum efficiency.

2. Improve package light extraction efficiency and lower junction temperature.

3. Improve the light extraction efficiency of the luminaire.

High color rendering

The LED display has many light color qualities, including color temperature, color rendering, light color fidelity, light color naturalness, hue recognition, and visual comfort. Here we are only discussing the issue of color temperature and color rendering. Producing a high color rendering LED display source will lose more light efficiency, so take care of these two factors when designing. Of course, to improve high color rendering, you must also consider the RGB three primary color combination to achieve. Here are my three methods:

1. Multi-primary phosphor powder.

2. RGB multi-chip combination.

3. Fluorescent powder plus chips.

High reliability

It mainly includes indicators such as failure rate and longevity. However, there are different understandings and explanations in the application. High reliability refers to the ability of a product to perform a specified function under specified conditions and within a specified time. The LED failure categories mainly have serious failures and parameter failures. Lifetime is a characterization of product reliability. : Generally refers to the statistical average. For a large number of components, the life of the LED device is the meaning of this description. However, factors affecting the reliability of LED display products include chip manufacturing, packaging, thermal resistance, and heat dissipation. Since this is the case, I hope that the company will make two requirements for the implementation of total quality control on LED display products:

1. Reduce failure rate.

2. Extend the loss of time.

Reduce product costs

At present, many consumers feel that the price is too high when they buy LED displays. Therefore, many LED display entrepreneurs have taken corresponding measures to reduce costs. In addition to mass production, they mainly take measures to reduce costs. Ways and means. Mainly in the epitaxial chip, packaging, drive, heat dissipation and other aspects to reduce costs, thereby fundamentally solving the cost of LED display products. Specifically speaking from the following four aspects:

1. The method of reducing the cost of the epitaxial chip link.

2. The method of reducing costs in the packaging process.

3. The method of reducing the cost of the lighting link.

4. Reduction of other supporting costs

The above is mainly to solve the main technologies of LED display and take corresponding measures from the four technologies of high luminous efficiency, high color rendering, high reliability and low cost. In general, in addition to adopting new technologies, new processes, new Structure, new materials and other measures to achieve high luminous efficiency, high color rendering, high reliability and low cost of LED display, from a deeper level, should improve energy efficiency and light color quality as the higher requirements of LED display, thus truly for people Provide demand on the product!
