Data processing method and device, driving method, display panel and storage medium

An image display driving method, comprising:

• obtaining input RGB graysc ale values;
• based on the input RGB grayscale values, calculating a chromaticity coordinate of the input RGB grayscale values on a chromaticity diagram, wherein the chromaticity diagram comprises a white basic point;
• calculating to obtain intermediate grayscale values containing a white component, based on the input RGB grayscale values and according to a position relationship between the chromaticity coordinate and the white basic point;
• adjusting the intermediate grayscale values to obtain output RGBW grayscale values;
• and
• driving a display pixel to display by using the output RGBW grayscale values.

A data processing device, comprising:

• a data acquisition module, configured to acquire input RGB grayscale values;
• a grayscale conversion module, which is configured for:
• based on the input RGB grayscale values, calculating a chromaticity coordinate of the input RGB grayscale values on a chromaticity diagram, wherein the chromaticity diagram comprises a white basic point;
• calculating to obtain intermediate grayscale values containing a white component, based on the input RGB grayscale values and according to a position relationship between the chromaticity coordinate and the white basic point;
• and
• adjusting the intermediate grayscale values to obtain output RGBW grayscale values;
• and
• an output module, which is configured for transmitting the output RGBW grayscale values to a display pixel to drive the display pixel to display.
