Method and system for generating images on display

A method for generating images on a display, comprising following steps:

• step S1, obtaining LCH values of a color n, obtaining first Lab values by calculation;
• converting the LCH values of the color n to Lab for obtaining the first Lab values;
• step S2, measuring a measured display by a color analyzer to obtain a first original value of the measured display, the first original value comprising tristimulus values of an R, G, B, W four colors full gray-scale, a gamma value of R, G, B, W four colors, tristimulus values of a pure white image, and chromatic values of pure red, pure green and pure blue;
• obtaining first tristimulus values of the color n according to the tristimulus values of the pure white image as reference values and the first Lab values;
• obtaining the first tristimulus values by conversion of the first Lab values;
• step S3, obtaining first output gray-scale values according to the first tristimulus values of the color n, the chromatic values of pure red, pure green and pure blue in the first original value, and the tristimulus values of the pure white image;
• converting the XYZ values to RGB values to obtain the first output gray-scale values;
• step S4, obtaining first input gray-scale values to be input to the display respectively according to the first output gray-scale values and the gamma value;
• step S5, obtaining second Lab values according to the first input gray-scale values and the tristimulus values of RGB three colors in the first original value;
• step S6, comparing the first Lab values and the second Lab values, when the first Lab values and the second Lab values are consistent, outputting the first input gray-scale values to the measured display for display, which is step S7.
