How many factors can affect the CR of an LED display?

 

 

1.Display technology
Different display types, such as LCD, OLED, and QLED, have different contrast capabilities. For example, OLED screens have excellent contrast ratios because they can turn off the pixels completely, providing true blacks and infinite contrast.

 

2.Backlight technology
The backlighting method affects the CR. Direct-mounted LEDs and full-array local dimming (FALD) allow for better control of the backlit area, resulting in higher ratios than edge-lit displays.

 

3.Panel quality
Panel quality affects CR. Better panels have a more consistent minimum brightness, resulting in accurate and consistent ratios.

 

4.Ambient lighting conditions
The lighting in the room affects the appearance of the CR. Bright lights can make the ratio look lower. In addition, it is important to consider the lighting of the room when using the screen.
