There are many factors that affect the display effect of LED displays, including the following basic factors, resolution and pixel density, brightness and contrast, gray scale and color.
Resolution refers to the number of horizontal and vertical pixels on the display screen, usually expressed as the number of horizontal pixels × the number of vertical pixels. The higher the resolution, the clearer the display effect and the finer the image details.
Pixel density refers to the number of pixels in a unit area, usually expressed in the number of pixels per square meter, so the higher the pixel density, the more delicate the display effect, and the closer the viewing distance can be.
Brightness determines the visibility of the screen in different environments, while contrast affects the sharpness of the image and the degree of color restoration.
Higher brightness can make the screen still visible in bright environments, while higher contrast can make the image more vivid.
In outdoor applications, the display requires long-term exposure to sunlight, and is more inclined to choose LED displays with higher brightness and contrast.
The gray level mainly depends on the number of digital-to-analog conversion bits of the system. Of course, the video processing chip, memory and transmission system of the system should provide the corresponding bit support.
