Abstract: An image processing apparatus including an image data processor unit is provided. The image data processor unit is configured to generate a plurality of partial output frames according to a plurality of input frames. With respect to one pixel in a display panel, each partial output frame among the partial output frames includes sub-pixel data corresponding to a part of sub-pixels in the pixel instead of sub-pixel data corresponding to all of the sub-pixels in the pixel. In addition, a display panel and a display apparatus are also provided.

Abstract: A display driver adapted to drive a display panel is provided. The display panel includes a pixel column direction and a pixel row direction. The display driver includes an image data processor unit. The image data processor unit performs a two-dimensional subpixel rendering operation on an input image data to generate an output image data. The display driver drives the display panel according to the output image data. The two-dimensional subpixel rendering operation includes a first one-dimensional subpixel rendering operation in a first direction and a second one-dimensional subpixel rendering operation in a second direction. The first direction is one of the pixel column direction and the pixel row direction, and the second direction is another one of the pixel column direction and the pixel row direction.

Abstract: An image processing apparatus including an image data processing unit is provided. The image data processing unit is configured to generate an output frame according to an input frame. For any one of sub-pixels of a display panel, the image data processing unit performs a sub-pixel rendering operation on a part of input sub-pixel data of the input frame to generate an output sub-pixel data corresponding to said any one of sub-pixels in the output frame. The output sub-pixel data is written into said any one of sub-pixels. Data positions that the parts of input sub-pixel data of different input frames locate in respective input frames are partially overlapped and not totally the same. In addition, a method for generating display data of the display panel is provided.
