Abstract

The application discloses a sub-pixel rendering method and a display driving device. The sub-pixel rendering method is used to drive a plurality of pixel units of a display panel, each pixel unit includes a plurality of sub-pixels of different colors, the method includes: obtaining a sub-pixel arrangement of the display panel; according to the sub-pixel arrangement and the pixel unit position, obtain the rendering unit of the pixel unit and the corresponding adjustment method; and according to the adjustment method, map the color component of each image pixel into the grayscale value of the internal sub-pixel of the pixel unit, and the Grayscale values ​​of multiple compensated sub-pixels. The sub-pixel rendering method can be applied to a general driver chip, so as to be suitable for display panels with different sub-pixel arrangements, thereby reducing design cost and manufacturing cost.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly to a sub-pixel rendering method and a display driving device. Background technique [0002] The display panel includes a plurality of pixel units, and each pixel unit includes a plurality of sub-pixels, for example, the plurality of sub-pixels are respectively used to display one of red, green and blue colors. When displaying an image, the image pixels correspond to the pixel units of the panel. In each pixel unit, the display of the image pixels is realized by controlling the brightness of multiple sub-pixels of different colors. Therefore, the use of multiple pixel units of the panel can realize Display of the full image. [0003] In an organic light emitting diode (abbreviated as OLED) display device, an organic light emitting diode is used as a sub-pixel unit. Different from conventional liquid crystal display devices, OLED display devices have high contrast r...
