Introduction to the selection of LED full color display elements

With the development of science and technology, our TV sets have gradually changed from black and white to color, and their radiation performance is greatly reduced compared with previous TV sets, especially the recent popular LED full color display. It is said that it adopts the most advanced high-end luminescent materials and high-quality dedicated IC chips, which not only has a good display effect, but also has a smooth display effect with a large viewing angle, and has occupied a dominant position in the current display market.

The main components of the LED full-color display are the power switch (which is responsible for the power-on display of the LED full-color display), the scanning control board (which is responsible for data buffering), the display unit (that is, the display screen portion), and the metal structure frame (control LED). Full color display frame), twisted pair transmission cable (transmission data), main controller (responsible for data buffering and combination and generation of various control signals), dedicated display card and multimedia card (the function is more on the computer display) Card function is similar), and other components, but with the continuous development of LED full-color display in recent years, the current LED full-color display on the market is also mixed in quality and price, so if you want to buy LED full color For the display, pay attention to the following points:

1, LED full color display display brightness

We know that the display mode of the LED full-color display is to achieve the imaging effect by the illumination of the LED, so once the brightness is not enough, the quality of the diode is not good, usually for the brightness of the LED full-color display. The brightness should be controlled above 800 cd/m2, while the outdoor requirements are higher, usually 1500 cd/m2 or more.

2, LED full color display is white balance

Zhengzhou LED display Shunxing Fengshuo Electronic Technology Co., Ltd. introduced, we know that if the display wants to display white, it needs to be displayed by the ratio of red, green and blue in the ratio of 1:4.6:0.16. Therefore, If the display control system of the display is not precisely controlled, it is easy to appear yellow, green, blue and other white display effects.

3. Is there a pixel on the LED full color display that cannot change color?

We know that the display image of the LED full-color display is composed of a small dot and the color of the dots is not fixed. If the image needs some small dots to be displayed in white, these small pixels will be displayed in white. If the display image needs these small dots to be displayed in red, these small dots need to be turned red again, so that the effect of the received image is always the same. If some necrotic pixels appear on the display, these pixels will affect the display. The display effect of the screen appears to be a constant or always black state, and the main cause of this phenomenon is determined by the quality of the die.

4, LED full color display whether color transition

That is to say, the color difference between the two adjacent display pixels is large, which leads to the uncoordinated display effect, and the main reason for this phenomenon is mainly because of the poor LED full-color display control system.

5, LED full color display surface is flat

Zhengzhou LED display Shunxing Fengshuo Electronic Technology Co., Ltd. pointed out that if you find that the surface of the LED full-color display is very rough, and there are some bumps in the local area, these will affect the LED full-color display. The display quality causes the display screen to be distorted, so that LED full-color display like this type should not be purchased. Generally, the flatness of the LED full-color display surface should be within 1mm of lusm.

6, color reproduction of LED full color display

Color reproduction means that the color received by the display should be consistent with the color it displays, otherwise it will not be restored, so as to ensure the authenticity of the LED display.
