Display driving method and liquid crystal display device

Abstract

The invention provides a display driving method and a liquid crystal display device. The display driving method includes the following steps: providing a liquid crystal display panel, the liquid crystal display panel includes a plurality of sub-pixels arranged in an array, setting every two adjacent sub-pixels of the same color in the liquid crystal display panel as a display unit; obtaining each The original grayscale value of the display unit; the original grayscale value of each display unit is processed to generate the first display grayscale value and the second display grayscale value of each display unit, and the first display grayscale value is greater than the second display grayscale value Gradation value; use the first display grayscale value and the second display grayscale value of each display unit to drive two sub-pixels in each display unit to display, and make one of any adjacent two sub-pixels in the liquid crystal display panel Driven by the first display grayscale value of its corresponding display unit, and the other is driven by the second display grayscale value of its corresponding display unit, which can improve the chromaticity and viewing angle of the liquid crystal display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving method and a liquid crystal display device. Background technique [0002] A Liquid Crystal Display (LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc., occupy a dominant position in the field of flat panel display. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter substrate (ColorFilter, CF), and apply a driving voltage on the two subst...

Problems solved by technology

[0005] Although the chromaticity and viewing angle of the liquid crystal display panel with eight-domain structure sub-pixels have been significantly improved compared with the liquid crystal display panel with four-domain structure sub-pixels, the liquid crystal display panel with in-plane switching (In-Plane Switching, IPS) mode Compared with display panels and organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panels, its chromaticity and viewing angle are still very low, which affects people's viewing experience under large viewing angles.
