LIQUID CRYSTAL DISPLAY PANEL AND DRIVING METHOD THEREOF

摘要

A liquid crystal display (LCD) panel and a driving method thereof are provided. The LCD panel includes display pixels each including RGBW display sub-pixels. The method includes: receiving an image data for representing a to-be-displayed image including image pixels; calculating RGBW image sub-pixel data corresponding to the image pixels according to the image data; using a first predetermined number of image pixels as a repeat unit and generating RGBW display sub-pixel data corresponding to a second predetermined number of display pixels by using each repeat unit in a pixel sharing manner, the first predetermined number being greater than the second predetermined number; and using the RGBW display sub-pixel data to drive RGBW display sub-pixels of corresponding display pixels. Accordingly, the edge blur phenomenon can be effectively improved by the image pixel sharing.

主权项

1. A driving method of a liquid crystal display panel, wherein the liquid crystal display panel comprises a plurality of display pixels, each of the plurality of display pixels comprises a red display sub-pixel, a green display sub-pixel, a blue display sub-pixel and a white display sub-pixel; the driving method comprises:
receiving image data, wherein the image data are for representing a to-be-displayed image including a plurality of image pixels; calculating red image sub-pixel data, green image sub-pixel data, blue image sub-pixel data and white image sub-pixel data corresponding to the plurality of image pixels according to the image data; and concretely using grayscale values of a red image sub-pixel, a green image sub-pixel and a blue image sub-pixel of each of the plurality of image pixels as the red image sub-pixel data, the green image sub-pixel data and the blue image sub-pixel data corresponding to the image pixel and using the minimum one of the grayscale values as the white image sub-pixel data corresponding to the image pixel; using six image pixels in the plurality of image pixels as a repeat unit and generating red display sub-pixel data, green display sub-pixel data, blue display sub-pixel data and white display sub-pixel data corresponding to three display pixels in the plurality of display pixels by each repeat unit; using the red display sub-pixel data, the green display sub-pixel data, the blue display sub-pixel data and the white display sub-pixel data to drive the red display sub-pixels, the green display sub-pixels, the blue display sub-pixels and the white display sub-pixels of corresponding display pixels.
