Abstract

The invention discloses a driving method of a liquid crystal display device, the liquid crystal display device comprises a liquid crystal display panel and N source electrode drivers driving the liquid crystal display panel, wherein N is an integer and is larger than or equal to 2. The driving method provides each source electrode driver with two polarity control signals so as to ensure opposite voltage polarities of corresponding sub-pixel between adjacent source electrode drivers, wherein the first polarity control signal is a polarity reverse signal of a plus phase or a polarity reverse signal of a minus phase; M polarity reverse signals of plus phase and M polarity reverse signals of minus phase are alternatively provided for all N source electrode drivers in the liquid crystal display device, wherein M is an integer and satisfies the formula: M is larger than or equal to 1 and is less than or equal to (N+1) / 2; the second polarity signal is a determined pin signal of high potential or low potential. The driving method can solve the problems of green attachment and interference, and reduces flickers.

Description

technical field [0001] The invention relates to a driving method of a liquid crystal display device, in particular to a driving method of a liquid crystal display device which can solve the problems of green adhesion and crosstalk and reduce flickering. Background technique [0002] figure 1 Shown is a block diagram of a driving circuit of a known thin film transistor liquid crystal display module. The thin film transistor liquid crystal display module mainly includes: liquid crystal display panel (LCD panel), source driver (SourceDriver, SD), gate driver (Gate Driver), timing controller (Tcon) and gray voltage generator (Gray Voltage Generator) . The signals transmitted to the liquid crystal display module include: R, G, B are display image signals; DE is an enable signal; MCLK is a clock signal; Vsync, Hsync are vertical synchronization signals and horizontal synchronization signals respectively. The timing controller transmits the row start signal STH, the positive pha...
