Abstract

The invention provides a display driving circuit. The display driving circuit is used for providing data signals for a corresponding display panel and comprises a conversion module, a selection module and a frame rate control module, wherein the conversion module is used for performing numerical bit conversion on original data signals, and according to the data signals after the numerical bit conversion, generating first display data signals used for main pixels and second display data signals used for sub-pixels; the selection module is used for, according to pixel brightness arrangement of a display panel, selecting the first display data signals or the second display data signals as corresponding data line signals; and the frame rate control module is used for performing image enhancement operation on the data line signals through an image frame rate control mode. The invention also provides a liquid crystal display panel. According to the invention, the power consumption and the manufacturing cost of the liquid crystal display panel are reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display driving circuit and a liquid crystal display panel. Background technique [0002] The display driving circuit of the existing liquid crystal display panel usually consists of a timing control module, an overdrive module, a white balance module, and a data conversion module. The purpose of white balance adjustment is to adapt to the subjective feelings of different races on color. It can convert the original data from 8bit to 12bit, adjust the proportion of red, green and blue in each white grayscale picture, and fine-tune the white The brightness of the gray scale makes the overall display conform to Gamma2.2. [0003] However, due to the optical anisotropy of liquid crystal molecules in existing liquid crystal displays, liquid crystal displays usually have the problem of color shift under large viewing angles, that is, it is easy to watch pictures with ...
