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 power on display of LED full-color display), scanning control board (responsible for data buffering), display unit (i.e. display screen part), metal structure frame (controlling the composition frame of LED full-color display), twisted pair transmission cable (transmitting data) 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 screen, you should pay attention to the following points first:
1. Brightness of LED full-color display screen
we know that the display mode of LED full-color display screen relies on the light emitting diode to achieve the imaging effect, so if the brightness is not enough, it means that the quality of the diode is not good, Generally speaking, for the brightness of LED full-color display screen, the indoor brightness should be controlled above 800cd / m2, and the outdoor brightness should be higher, usually above 1500cd / m2.

2. Is the LED full-color display screen white balance?
introduction of Zhengzhou LED display screen Shunxing fengshuo Electronic Technology Co., Ltd.
2We know that if the monitor wants to display white, it needs red, green and blue in a ratio of 1:4.6:0.16 to display it. Therefore, if the control system of the monitor does not have accurate control, it is easy to show yellow, green, blue and other white display effects.

3 Whether there are pixels that can't change color on LED full-color display screen
we know that the display image of LED full-color display screen is composed of dots, and the luminous color of these dots is not fixed.
if the display image needs some dots to be white, these 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. The color transition occurs
that is to say, the color difference between the two adjacent display pixels is very large.
this leads to the uncoordinated display effect, and the main reason for this phenomenon is the poor control system of the LED full-color display screen.

5 Whether the surface of LED full-color display screen is smooth or not
Zhengzhou LED display screen Shunxing fengshuo Electronic Technology Co., Ltd. points out.
when purchasing led full-color display screen, 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 screen and lead to distortion of display screen, So you don't want to buy this type of LED full-color display,Generally speaking, the flatness of LED full-color display screen surface should be within ± 1mm.

6. Color reducibility of LED full-color display screen means that the color received by the display screen should be consistent with the color displayed by it, otherwise it is not called restoration, so as to ensure the authenticity of LED display effect.
it is OK.
