Abstract: A data processing method, an image display driving method, a data processing device, a display panel and a computer-readable storage medium are provided. The data processing method includes: based on input RGB grayscale values, calculating a chromaticity coordinate of the input RGB grayscale values on a chromaticity diagram, in which the chromaticity diagram includes 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.

Abstract: A color gamut conversion method, a color gamut converter, a display device, an image signal conversion method, a computer device and a non-transitory storage medium are disclosed. The method includes: acquiring RGB signals and a preset grayscale value of a white subpixel in each pixel of a converted image according to grayscale values of monochromatic subpixels in each pixel of an original image corresponding to the RGB signals, the converted image is obtained by converting the original image from an RGB gamut to an RGBW gamut; and acquiring a target grayscale value of the white subpixel at least according to a first maximum grayscale of the white subpixels and the preset grayscale. As for a first saturation color patch in the original image, a first maximum grayscale of a white subpixel corresponding to each pixel in the first saturation color patch is equal to a grayscale threshold.
