What is the contrast ratio of the display

The brightness contrast between the brightest and darkest of a display is called contrast. The higher the contrast, the stronger the layering of the picture quality and the stronger the detail expression. This greatly improves the visual effect of the LED display.

The classification of contrast generally includes:
1. Static contrast
2. Dynamic contrast

There are many ways to improve contrast, such as using better quality LED lamp beads and adjusting and optimizing in a darkroom. Generally, large factories will build their own darkrooms to do color correction and other work.
