Method for generating chromaticity calibration compensation table and mobile terminal

A method for generating a chromaticity calibration compensation table, wherein the chromaticity calibration compensation table is applied to a display panel, and the generation method is applied to a first processor, wherein the display panel has a plurality of pixel units, and each of the pixel units has a plurality of primary color sub-pixels, and wherein the generation method at least comprises:

• an acquisition step of acquiring luminance information of the display panel, wherein the luminance information at least comprises a mapping relationship and a plurality of predetermined luminance data, wherein the mapping relationship is between a plurality of pieces of actual chromaticity information and output grayscales of each of the primary color sub-pixels, comprising:
• measuring pieces of primary color chromaticity information that each of the primary color sub-pixels has when each of the primary color sub-pixels individually displays the output grayscales that each of the primary color sub-pixels is configured with;
• respectively selecting and adding one piece of the pieces of the primary color chromaticity information of each of the primary color sub-pixels together multiple times, to obtain the mapping relationship between the pieces of the actual chromaticity information and the output grayscales of each of the primary color sub-pixels;
• and
• using the mapping relationship as the luminance information of the display panel;
• a calculation step of, according to predetermined color information in a predetermined chromaticity system, and the predetermined luminance data, calculating a plurality of pieces of ideal chromaticity information that the display panel should have when the display panel displays a plurality of target grayscales with an ideal display effect;
• and
• a generating step of matching the pieces of the actual chromaticity information and the pieces of the ideal chromaticity information to generate the chromaticity calibration compensation table, wherein the chromaticity calibration compensation table indicates the output grayscale that each of the primary color sub-pixels should be configured with when the display panel displays each of the target grayscales with the ideal display effect;
• wherein the first processor at least comprises a calculation module, and an acquisition module and a generation module coupled to the calculation module, wherein the acquisition module is configured to perform the acquisition step, the calculation module is configured to perform the calculation step, and the generation module is configured to perform the generation step,
• wherein the output grayscales have more levels than the target grayscales.
