Abstract: This application discloses a sub-pixel rendering method, and relates to the field of displaying. It is capable of making improvement with respect to the problem of distortion in the boundary region of the displayed image while ensuring a relatively high resolution of the display. The sub-pixel rendering method comprises: receiving a digital image; dividing, according to color values of image pixels in the digital image, the image pixels into boundary region pixels and continuous region pixels; generating a plurality of screen pixels on a screen, each screen pixel at least including one red sub-pixel, one blue sub-pixel, and one green sub-pixel, one of the plurality of screen pixels being used for correspondingly displaying one of the image pixels; wherein adjacent screen pixels for displaying the continuous region pixels share sub-pixels, and each screen pixel for displaying the boundary region pixels exclusively uses its sub-pixels.

Abstract: An organic light-emitting diode display unit, a driving method thereof and a display device are disclosed. At least part of pixel units are pixel units each with a stacked structure; each pixel unit with the stacked structure includes two adjacent subpixel unit stacked groups; and each subpixel unit stacked group includes at least two subpixel units which have different emitting colors and are stacked and insulated from each other. During display of different image frames, each subpixel unit stacked group in each pixel unit with the stacked structure can display gray-scale effect of at least two colors based on applied signals. Compared with an approach that each subpixel unit can only display gray-scale effect of only one color for different image frames, the display effect can be improved.
