Color temperature adjustable display system and color temperature adjusting method

Abstract

The invention discloses a color temperature adjustable display system comprising a color temperature setting device, an application processor, a display module group and a backlight module group. The input end of the application processor is connected with the color temperature setting device. The output end of the application processor is connected with display module group and the backlight module group. The application processor comprises a pulse width controller and a graphic data transmitter. The backlight module group comprises a backlight driver and backlight lamp groups which are connected. The backlight lamp groups comprise at least one cool color lamp group and at least one warm color lamp group. The color temperature setting device converts color temperature settings of a user into color temperature parameter signals to be transmitted to the pulse width controller. The pulse width controller converts the color temperature parameter signals into pulse width modulation signals and controls the brightness of the cool color lamp groups and the brightness of the warm color lamp groups through the backlight driver. The color temperature adjustable display system is high in electro-optical conversion efficiency, low in energy consumption and suitable for a liquid crystal panel of red, green, blue and white pixel arrangement.
