Color Adjustment Device, Method for Adjusting Color, and Display for the Same

A color adjusting device, characterized in that:

• the color adjusting device comprises:
• a measuring unit for measuring a measured stimulus set (WXp, WYp, WZp/RXM, RYM, RZM/GXL, GYL, GZL/BXN, BYN, BZN) performing as white, red, green and blue at all grayscales on a LCD panel, where p, M, L, N=0, 1, 2, . . . , 255;
• a first conversion unit, connected to the measuring unit, for converting a predetermined white-measured stimulus set (WX255, WY255, WZ255) of the plurality of measured stimulus sets (WXp, WYp, WZp) into a target chromatic set comprising a target luminance value WYp, a first target chromatic value WXp, and a second target chromatic value WYp of each of white grayscales, where WYp=WY255×(p/255)2.2, Wxp=WX255/(WX255+WY255+WZ255), WYp=WY255/(WX255+WY255+WZ255), p=0, 1, 2, . . . , 255;
• a second conversion unit, connected to the first conversion unit, for converting the target chromatic set of each white grayscale into a plurality of white target stimulus sets (WX′p, WY′p, WZ′p), each white grayscale corresponding to a target stimulus set and each target stimulus set comprising three target stimulus values WX′p, WY′p, WZ′p, where WY′p=WY255×(p/255)2.2, WX′p=WX255×(WY′p/WY255), WZ′p=(1−WXp−WYp)×(WY′p/WYp), p=0, 1, 2, . . . , 255;
• and
• a calculation unit, connected to the second conversion unit, for calculating each set of RGB ratios for each white grayscale, based on the corresponding white target stimulus set (WX′p, WY′p, WZ′p) and the measured stimulus set (WXp, WYp, WZp) of the corresponding grayscale.

A display comprising a liquid crystal display (LCD) panel, the LCD panel comprising a plurality of pixels for displaying an image, each pixel comprising a plurality of sub-pixels, characterized in that:

• the display further comprises a color adjustment device, the color adjustment device comprising:
• a measuring unit for measuring a measured stimulus set (WXp, WYp, WZp/RXM, RYM, RZM/GXL, GYL, GZL/BXN, BYN, BZN) performing as white, red, green and blue at all grayscales on a LCD panel, where p, M, L, N=0, 1, 2, . . . , 255;
• a first conversion unit, connected to the measuring unit, for converting a predetermined white-measured stimulus set (WX255, WY255, WZ255) of the plurality of measured stimulus sets (WXp, WYp, WZp) into a target chromatic set comprising a target luminance value WYp, a first target chromatic value WXp, and a second target chromatic value WYp of each of white grayscales, where WYp=WY255×(p/255)2.2, WXp−WX255/(WX255+WY255+WZ255), WYp=WY255/(WX255+WY255+WZ255), p=0, 1, 2, . . . , 255;

• and
• a calculation unit, connected to the second conversion unit, for calculating each set of RGB ratios for each white grayscale, based on the corresponding white target stimulus set (WX′p, WY′p, WZ′p) and the measured stimulus set (WXp, WYp, WZp) of the corresponding grayscale.
