A brief discussion on LED SMD Screen electronic display issues

LED SMD Screen electronic displays are used more and more widely in life, and the technology for large-screen displays has also been improved.

At present, LCD displays are very promising due to their excellent display effects, but the splicing technology in large-screen displays has not yet been developed. Reaching a seamless level, LED SMD Screen small spacing successfully made up for this shortcoming and successfully emerged.

In the period when LCD large-screen seamless splicing technology matured, LED SMD Screen electronic displays jumped up and dominated the large-screen display market.

Solving technical problems of LED electronic display SMD Screen

The first is high luminous efficiency: The luminous efficiency of LED SMD Screen electronic displays can be said to be an important indicator of energy-saving effect. At present, Pakistan’s luminous efficiency still needs to be strengthened.

To truly achieve high luminous efficiency, relevant issues must be solved from all aspects of the industrial chain. Technical question, so how to achieve high light efficiency? This article will specifically discuss the technical issues to be solved in epitaxial, chips, packaging, lamps and other links.

1. Improving internal quantum efficiency and external quantum efficiency is necessary.
2. Improve package light efficiency and reduce junction temperature.
3. Lamps need to improve their light extraction efficiency.

Secondly, from the perspective of high color rendering: LED SMD Screen electronic displays have many light and color qualities, including color temperature, color rendering, light and color fidelity, light and color naturalness, hue recognition, visual comfort, etc.

Here we currently only discuss solving the problem of color temperature and color rendering. Making a high color rendering LED SMD Screen display light source will lose more light efficiency. So these two factors must be taken into consideration when designing.

Of course, to improve high-color rendering, the combination of RGB three primary colors must be considered. Here I have three methods:

1. Multi-primary color phosphor.
2. RGB multi-chip combination.
3. Add phosphor to chip.

Again, from the perspective of high reliability: Mainly including failure rate, lifespan and other indicators. However, there are different understandings and explanations in application. High reliability refers to the ability of a product to complete specified functions under specified conditions and within a specified time.

SMD LED failure categories mainly include serious failure and parameter failure. The life span is a representative value of product reliability. Generally refers to the statistical average. For a large number of components, the life of the LED SMD Screen device is the meaning of this description.

However, factors that affect the reliability of SMD Screen display products include chip manufacturing, packaging, thermal resistance, heat dissipation, etc.

Now that we are talking about this, we hope that companies will make two requirements for LED SMD Screen display products on the basis of comprehensive quality control:

1. Reduce the failure rate.
2. Extend the expiration time of consumption.

The last step is to reduce product costs: At present, many consumers feel that the price is too high when purchasing LED SMD Screen displays. Therefore, many LED display manufacturers have also taken corresponding measures to reduce costs.

In addition to mass production, mainly take technical measures to reduce costs. The main purpose is to reduce costs in terms of epitaxial chips, packaging, drivers, heat dissipation, etc.

Thereby fundamentally solving the cost problem of LED display products. Specifically, it will be discussed from the following four aspects:

1. Methods to reduce costs in the epitaxial chip link.
2. Methods to reduce costs in the packaging process.
3. Methods to reduce costs in the lighting segment.
4. Reduction of other supporting costs.

How to control and improve the quality of LED full-color display

The display effect of the full-color LED display is directly related to users and audiences. In order to obtain a perfect user experience. It is necessary to control and improve the quality of the LED display.

So, how to control and improve the quality of LED SMD Screen full-color display? What are the important indicators that reflect the LED quality of full-color LED SMD Screen displays?

LED devices are key components of full-color LED SMD Screen displays for three reasons

First of all, the LED SMD Screen is a key component used in large quantities in a full-color screen machine. With thousands to tens of thousands of LEDs used per square meter.

Secondly, LED is the main body that determines the optical display performance of the entire screen. In which directly affects the audience’s evaluation of the display screen.

Thirdly, LED accounts for a large proportion of the overall cost of the display screen, ranging from 30% to 70%. The choice of LED determines more than 50% of the quality of the entire display screen.

If you fail to choose a good Mustang LED, no matter how good the other parts of the display are, they cannot make up for the shortcomings of the display quality.
