Description
Technical Field
The present invention relates to the field of display technologies, and in particular, to a display driving method and a liquid crystal display device.

Liquid Crystal Displays (LCDs) have many advantages such as thin body, power saving, no radiation, and the like, and are widely used. Such as: liquid crystal televisions, mobile phones, Personal Digital Assistants (PDAs), digital cameras, computer screens, notebook computer screens, or the like, are dominant in the field of flat panel displays.
Most of the existing liquid crystal displays in the market are backlight liquid crystal displays (lcds), which include a liquid crystal display panel and a backlight module (backlight module). The liquid crystal display panel operates on the principle that liquid crystal molecules are filled between a Thin Film Transistor Array Substrate (TFT Array Substrate) and a Color Filter Substrate (CF), and a driving voltage is applied to the two substrates to control the rotation direction of the liquid crystal molecules, so that light of the backlight module is refracted out to generate a picture.
Because liquid crystal molecules have optical anisotropic characteristics, the conventional liquid crystal display panel has the problems that the visual angle is narrow and the wide visual angle cannot be realized. In order to enlarge the viewing angle of the liquid crystal display panel, the prior art method includes a multi-domain pixel structure and a pre-processing of the input data signal voltage by a viewing angle compensation algorithm, wherein the multi-domain pixel structure is to subdivide each Sub-pixel in an image pixel into smaller display units, for example, one Sub-pixel is divided into a Main area (Main) and a Sub-area (Sub), and the driving voltages of the Main area and the Sub-area are in a certain proportion, so that the liquid crystal molecules corresponding to the Main area and the Sub-area are deflected into different angles, and therefore, a better viewing effect can be obtained from different angles. The specific implementation steps of the viewing angle compensation algorithm comprise: setting every two adjacent sub-pixels with the same color in the liquid crystal display panel as one display unit, providing original gray scale data for each display unit, respectively generating first display gray scale data and second display gray scale data according to the original gray scale data of each display unit, and respectively controlling the display brightness of the two sub-pixels in the display unit by utilizing a first display gray scale value and a second display gray scale value, wherein the first display gray scale value is larger than the second display gray scale value, so that the driving voltages applied to the two sub-pixels are different, the liquid crystal molecules of the two sub-pixels are deflected into different angles, the image can be viewed at different angles, better viewing effect can be obtained, and the purpose of reducing color cast can be achieved.
In the existing visual angle compensation algorithm, in each frame of picture, the sub-pixels in the odd-numbered rows are set to display brighter first display gray scale data, and the sub-pixels in the even-numbered rows display darker second display gray scale data, so that when displaying, the sub-pixels in the odd-numbered rows and the sub-pixels in the even-numbered rows are always brighter and darker, so that bright and dark stripes appear in the display picture, and the display quality is affected.
