1. Look at the flatness of the screen: In order to ensure that the displayed image will not be distorted, the surface flatness of the outdoor LED display must be kept within ±1mm. This leads to the problem that the viewing angle of the outdoor LED display has a dead angle when playing video. Therefore, it can be said that flatness is a major factor in judging a high-quality outdoor LED display.

2. Look at the brightness of the screen: Under normal circumstances, the brightness of the outdoor LED display should reach 1500cd/m2 or more to ensure normal display work, otherwise it will be difficult to see the content of the displayed image because of insufficient brightness. Therefore, if you want to buy an outdoor LED display with a good display effect, you must look at the quality of the LED lamp beads and their brightness parameters.

3. Look at the white balance of the screen: when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16, the screen will display the purest white. Therefore, if the display screen produced by the outdoor LED display manufacturer is in the ratio of the three primary colors A slight deviation will lead to a deviation in the white balance, which will affect the display quality of the outdoor LED display, so it is also very important to look at the white balance when purchasing.

The above three aspects are several points that you can refer to when purchasing outdoor LED displays. When buying an outdoor LED display, everyone hopes to have a good playback effect, so it is necessary to purchase from the flatness, brightness and white balance of the display to ensure that the LED display you buy is good. .
