Abstract

The invention discloses a display device and a method for processing the color data of the same, wherein the display device comprises a display unit, a display control circuit and a color processing module; the display control circuit is used to receive input red, green and blue signals, so as to indicate the color processing module to correct the input red, green and blue signals and to control the display unit to display the image picture determined by a corrected object color signal returned by the color processing module; the color processing module, according to the indication of the control circuit, is used to inquire a standard color space corresponding to the input red, green and blue signals according to a standard color look up table; moreover, an equipment color look up table acquires the object color signal corresponding to the inquired standard color space, and corrects the input red, green and blue signals to the acquired object color signal which is sent to the display control circuit. On the basis of ensuring color reductibility, the display device can carry out correction management of an image picture.

Description

technical field [0001] The invention relates to color management technology, in particular to a display device and a color data processing method thereof. Background technique [0002] At present, LED-backlit liquid crystal displays using light-emitting diodes (Light Emitting Diode, hereinafter referred to as: LED) as the backlight have gradually become the mainstream in the field of liquid crystal display due to their advantages such as good color rendering, mercury-free environmental protection, and long service life. display device. LED-backlit liquid crystal displays have high color reproduction, which can reach more than 100% of the National Television Systems Committee (National Television Systems Committee, hereinafter referred to as: NTSC) standard at present, and can bring richer visual enjoyment to viewers. [0003] The LED backlight uses red, green and blue three primary color LEDs to mix light, and the desired white backlight is obtained by adjusting the current...
