Title
Proposal for Color Management of LCD
Abstract
A color profile that is suitable for the color management of LCDs is proposed. The color coordinates of primary colors and reference white of the LCDs has been reported to displace depending on its code value. These problems relate to essential characteristics of the LCDs that can only realize a limited range of contrast. Since the conventional ICC profile cannot describe effects due to the limited range of contrast, it has been unable to provide effective color management for the LCDs. In order to realize the color management that can satisfy the actual LCD performance, we propose following two points: (1) The tri-stimulus value (X(O)Y(O)Z(O)) obtained through the measurement of leakage light due to the limited contrast ratio of the LCD shall be added to conventional display device profile. (2) For the color management system, (X(O)Y(O)Z(O)) shall be subtracted in advance from the tri-stimulus value (X(T)Y(T)Z(T)) of the target color, and then result of the subtraction should be sent to the display. Experimental results showed that the use of the profile and CMS proposed in this paper enabled the color reproduction error to be low. The effect in improving the color management under an ambient light condition is also demonstrated.
