Description

technical field

[0001] The present invention relates to a device and method for adjusting backlight, in particular to a device and method for adjusting backlight applied to red, green, blue and white light display systems. Background technique

[0002] The red, green, blue and white (RGBW) display is based on the traditional red, blue and green (RGB), adding white light (W). Because white light does not require color filters, it can provide higher brightness than traditional red, blue and green displays, and can reduce the power consumed by the backlight. Compared with the red, green, blue and white light display, the red, green, blue and white light display has two advantages: 1. Under the same power, the red, green, blue and white light display can provide higher brightness; 2. In the Under the same brightness, the red, green, blue and white light display saves more power.

[0003] Although the red, green, blue and white light display has the above advantages, when displ...
