With the development of science and technology, our TV sets have gradually changed from black and white to color, and its radiation performance is greatly reduced compared with previous TV sets. Especially for the recently popular led full-color display screen, it uses the most advanced high-end luminous materials and high-quality special IC chips, which not only has good display effect, but also has a smoother display effect with a large viewing angle, It has occupied the leading position in the current display market.
With the development of science and technology, our TV sets have gradually changed from black and white to color, and its radiation performance is greatly reduced compared with previous TV sets. Especially for the recently popular led full-color display screen, it uses the most advanced high-end luminous materials and high-quality special IC chips, which not only has good display effect, but also has a smoother display effect with a large viewing angle, The main components of LED full-color display are power switch (responsible for the power on display of LED full-color display), scanning control board (responsible for data buffering), display unit (i.e. display screen), metal structure frame (controlling the composition frame of LED full-color display), twisted pair transmission cable (transmitting data), etc However, with the continuous development of LED full-color display in recent years, the quality and price of LED full-color display in the market are also uneven, Therefore, if you want to buy led full-color display, you should pay attention to the following points: 1. Brightness of LED full-color display. We know that the display mode of LED full-color display depends on the light emitting diode to achieve the imaging effect. Therefore, if the brightness is not enough, the quality of LED is not good, Generally speaking, for the brightness of LED full-color display screen, the indoor brightness should be controlled above 800cd / m2, while the outdoor brightness should be higher, usually above 1500cd / m2.

2. Is the LED full-color display screen white balanced? Zhengzhou LED display screen Shunxing fengshuo Electronic Technology Co., Ltd.
we know that if the display wants to display white,It needs red, green and blue to be displayed in the ratio of 1:4.6:0.16. Therefore, if the control system of the display does not have accurate control, it is easy to have white display effects such as yellow, green and blue Whether there are pixels that can not change color on LED full-color display screen? We know that the display image of LED full-color display screen is composed of small dots, and the luminous color of these dots is not fixed.
if the display image needs some small dots to be white, these small pixels will be white, If the display image needs these dots to be red, then these dots need to be red, so as to keep up with the received image effect. If there are some necrotic pixels on the display, these pixels will affect the display effect of the display screen, showing some constant or constant black state, The main reason for this phenomenon is due to the quality of the die.
4. Color transition, that is to say, the color difference between the two adjacent display pixels is very large.
this leads to the display effect discordance, and the main reason for this phenomenon is the poor control system of the LED full-color display screen.
5 Zhengzhou LED display Shunxing fengshuo Electronic Technology Co., Ltd. points out whether the surface of LED full-color display is smooth.
when you buy led full-color display, if you find that the surface is very rough, and there are concave convex and other conditions in some parts, these will affect the display quality of LED full-color display and lead to distortion of the display, In general, the surface flatness of LED full-color display should be within ± 1 mm.
6. The color reducibility of LED full-color display refers to the color reducibilityThe color received by the display screen should be consistent with the color displayed, otherwise it is not called restoration, so as to ensure the authenticity of the display effect of the LED display.
