不同色温环境光下彩色电润湿电子纸的色彩校正OACSTPCD

In order to solve the problem that the color of the reflective display color electrowetting display is inconsistent under ambient light with different color temperatures,which affects the color reproduction of the displayed picture,a color correction method based on the spectral reflectance characteristics of color electrowetting display is proposed.The spectral correspondence of the display color under ambient light with different color temperatures is obtained through the spectral reflectance characteristics of color electrowetting display,so as to establish the mapping relationship of the display color of color electrowetting display under ambient light with different color temperatures.According to the mapping relationship,the input color data is corrected to reduce the color difference of the displayed colors under ambient light with different color temperatures.The experimental results show that the chromaticity data of 100 test color blocks before and after the correction by the method in the two experimental light sources are reduced by 55%and 35%respectively with the average color difference of the standard light source,and the average subjective evaluation Z-scores of the corrected display images are 0.45 and 0.25.
