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 (color filter, CF), and driving voltages are 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 existing liquid crystal display panel has the problems that the chromaticity and the visual angle are narrow, and the viewing experience of people under a large visual angle is influenced. In order to achieve narrow viewing angle for improving chromaticity of a liquid crystal display panel, a multi-domain pixel structure is proposed in the prior art, in which each Sub-pixel is subdivided into smaller regions (domains) so that liquid crystal in each region can be directed to different directions, typically, for example, a four-domain structure, i.e., a pixel electrode of one Sub-pixel is made in a shape of a "m", so that the pixel electrode is divided into four regions, and liquid crystal in each region is directed to different directions during driving, and further, the four-domain structure is improved, and an eight-domain structure is proposed, i.e., a pixel electrode of one Sub-pixel is firstly divided into a Main region pixel electrode (Main) and a Sub-region pixel electrode (Sub), both the Main region pixel electrode and the Sub-region pixel electrode are in the shape of a "m", and driving voltages applied to the Main region pixel electrode and the Sub-region pixel electrode are in a certain ratio, so that eight domains are formed in one Sub-pixel, the viewing angle can be further improved compared to the four-domain structure.
Although the liquid crystal display panel with the sub-pixels having the eight-domain structure has a significantly improved chromaticity viewing angle compared to the liquid crystal display panel with the sub-pixels having the four-domain structure, the chromaticity viewing angle is still very low compared to the In-Plane Switching (IPS) mode liquid crystal display panel and the Organic Light-Emitting Diode (OLED) display panel, thereby affecting the viewing experience of people at large viewing angles.
