Abstract

The application discloses a sub-pixel rendering method, a driving chip and a display device. The sub-pixel rendering method includes obtaining the sub-pixel arrangement of the display panel; according to the sub-pixel arrangement and the position of the pixel unit, obtaining the rendering unit of the pixel unit and the brightness rendering coefficient and scaling coefficient of the corresponding sub-pixel, and according to the Brightness rendering coefficients and scaling coefficients, adjusting the gray scale driving parameters of each image pixel to change the luminous brightness of the corresponding sub-pixels, wherein the plurality of pixel units include a first pixel unit and a second pixel unit, The rendering unit of the first pixel unit includes only the internal sub-pixels of the first pixel unit, and the rendering unit of the second pixel unit includes the internal sub-pixels of the second pixel unit and adjacent first pixel units Compensation sub-pixels. The sub-pixel rendering method can reduce the number of sub-pixels of the display panel, thereby reducing design cost and manufacturing cost.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly relates to a sub-pixel rendering method driving chip and a display 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 hi...
