    摘要: The present disclosure provides an image processing method and a display device including rows of actual pixels each including actual sub-pixels, and starting positions of actual sub-pixels in odd-numbered and even-numbered rows are staggered by a distance of half of an actual sub-pixel. The method includes: determining rows of theoretical pixels corresponding to a to-be-displayed image, each theoretical pixel including theoretical sub-pixels, each actual pixel corresponding to at least two theoretical pixels; calculating grayscale data of each actual sub-pixel in a manner of: for a target actual pixel, determining a rendering mode for calculating grayscale data of each actual sub-pixel of the target actual pixel according to whether there is a specified detail feature in a pixel area where target theoretical pixels corresponding to the target actual pixel are located, different rendering modes are employed when there is or there is not a specified detail feature in the pixel area.

    摘要: An image display processing method for a display device, an image display processing device, a display device, and a non-volatile storage medium are provided. The display device includes a display panel and a backlight unit which includes a plurality of backlight blocks and is driven in a local dimming mode. The method includes: determining a first display area and a second display area of the display panel; obtaining backlight values of the backlight blocks, and calculating compensated display data of respective pixels corresponding to the backlight blocks based on the backlight values of the backlight blocks; and adjusting compensated display data of at least one first pixel comprised in the first display area to obtain adjusted display data of the at least one first pixel. A display resolution of the first display area is larger than a display resolution of the second display area.

    摘要: A display device and a method for driving the display device are described, where the display device includes a plurality of pixel island groups, a plurality of lenses, a positioning module, and a gate driving chip. The plurality of pixel island groups are arranged in array, wherein each of the pixel island groups includes a plurality of pixel islands, and different pixel islands are able to be scanned in different scanning modes. The positioning module is configured to determine a gaze area and a non-gaze area according to gazed coordinates of human eye. The gate driving chip is configured to provide gate driving signals in a first driving manner to sub-pixel units in the gaze area, and provide gate driving signals simultaneously in a second driving manner to sub-pixel units in the non-gaze area during a scanning stage of the sub-pixel units in the non-gaze area.

    摘要: The present disclosure provides a method and a device for obtaining display compensation information, a display compensation method and a display compensation device. The method includes: obtaining target data in a pure-color image displayed by a display panel, the display panel including a plurality of pixels, each pixel includes a plurality of monochromatic light-emitting elements in various colors, each monochromatic light-emitting element in a corresponding color being configured to display an image at a highest grayscale value when the pure-color image is displayed by the display panel; determining a conversion matrix for a target gamut of the display panel and a pixel conversion matrix for each pixel in accordance with the target data; and determining a uniformity conversion matrix for performing brightness and chromaticity uniformity compensation on each pixel in accordance with the pixel conversion matrix and the conversion matrix for the target gamut. According to the present disclosure, it is able to improve the brightness uniformity and the chromaticity uniformity of the display panel.
