What are the factors that determine the quality of a full-color LED display?

As a new cultural media tool, full-color LED displays have been widely used in various fields, such as: exhibitions, seaports, airports, subway stations, large and medium-sized sports culture and exhibition halls, intelligent transportation fields, etc., basically all related systems software and fields. Choosing a LED with high-quality characteristics is the basic standard for making a LED display with excellent performance. But what are the factors that determine the quality of a full-color LED display? The professional and technical personnel of Lianhuiye will introduce it to you below.

1. Uniformity and clarity hinder the improvement of LED display clarity mainly due to the flatness rather than the physical clarity interval. The flatness of the surface of the LED display screen should be within ± millimeters to ensure that the displayed image does not Distortion, partial protrusion or depression will cause blind spots in the viewing angle of the display screen. The key to the quality of flatness is determined by the production process. 2. Brightness and angle The angle of the display screen should solve the problem of luminous flux consumption. The brightness of the indoor full-color display screen should be above 800cd/m2, and the brightness of the outdoor full-color display screen should be above 1500cd/m2. Make sure that the display screen is working properly, otherwise the displayed image will not be clear due to the low brightness.

The size of the brightness is mainly determined by the quality of the LED core tube. 3. There are many reasons why the display resolution cannot be controlled, and the most important reason is "LED failure". The main cause of LED failure can be divided into two levels: one is the poor quality of the LED itself; the other is the poor operation method.

According to the analysis, we have sorted out the corresponding relationship between the LED failure mode and the above two main causes. 4. Energy consumption and energy consumption level Improve LED special effects and reduce display energy consumption is an important development prospect of LED display technology. It has the following significance: first, environmental protection and energy saving, energy saving and emission reduction, and protection of the ecological environment; Expansion of power engineering, capital investment in electromechanical equipment and cooling equipment; third, saving water and electricity costs and reducing operating costs; fourth, reducing display temperature rise; fifth, slowing down the rate of LED attenuation coefficient; sixth, improving reliability indicators; seventh, increasing display life ; The eighth is to reduce the temperature drift of the optical parameters of the display screen and stabilize the image effect. 5. Lifespan The lifespan of an LED display is determined by a variety of factors, because when the display is working, not every LED will be overloaded all the time, and the display is in the state of playing music and variety shows normally. Under normal circumstances, the life of the display screen should be 6 to 10 times that of the LED, and the life of the LED can be longer when the LED is working with a small amount of current.

Therefore, the lifespan of a display screen using this brand of LED reaches about 50,000 hours. The professional and technical personnel of United Huiye introduced to you the five key factors that determine the quality of full-color LED displays, including flatness and clarity, brightness and angle, uncontrollable clarity rate, energy consumption and energy consumption level, and life span. In this regard, compared with traditional lighting and decorative lighting, the output power is several times lower, but the effect is much better. In the design of the driver IC, technologies such as energy-saving and emission-reducing wiring, application of high-brightness LED lights on the package, and constant-current power supply bottom voltage have been greatly added, which has achieved remarkable results in energy-saving and emission-reduction.
