Liquid crystal display panel and driving method thereof

Abstract

The invention provides a liquid crystal display panel and a driving method of the liquid crystal display panel. The liquid crystal display panel comprises a plurality of pixel units which are arranged in an array mode, a first common electrode wire and a second common electrode wire, wherein more than two successive rows of successive pixel units form one set, and multiple sets of pixel units are formed. Any two adjacent rows of pixel units in each set are respectively connected with the first common electrode wire and the second common electrode wire, the last row of pixel units of the former set of the two adjacent sets and the first row of pixel units of the later set of the two adjacent sets are connected to the same common electrode wire, the common voltage reversing cycle of the first common electrode wire and the common voltage reversing cycle of the second common electrode wire are the same and mutually opposite in phase, and every time one set of the pixel units is scanned, the common voltage reversing cycle of the first common electrode wire and the common voltage reversing cycle of the second common electrode wire are reversed once. The liquid crystal display panel and the driving method of the liquid crystal display panel can avoid the phenomena of whitening, blackening and abnormal gradual change of colors, and can lower the power consumption.

Description

technical field [0001] The invention relates to flat panel display technology, in particular to a liquid crystal display panel and a driving method thereof. Background technique [0002] TFT (Thin Film Transistor, Thin Film Field Effect Transistor) means that each liquid crystal pixel unit point on the liquid crystal display is driven by a thin film transistor integrated behind it, so that a high-speed, high-brightness, high-contrast display screen can be achieved Information, the common TFT-LCD (Thin Film Transistor Liquid Crystal Display) is one of the most liquid crystal displays. [0003] Conventional liquid crystal display devices display images by controlling the rotation of liquid crystal molecules using an electric field. Such as figure 1 As shown, a conventional liquid crystal display device generally includes: a liquid crystal panel 100, a plurality of data lines 101 formed on the liquid crystal panel 100, a plurality of gate lines 102, a common electrode line 10...

Problems solved by technology

However, image 3 The structure of the liquid crystal panel 100 shown has a problem: at the beginning of a frame, the first common voltage Vcom1 and the second common voltage Vcom2 undergo an inversion, and then each gate line circuit 104 is sequentially connected to the gate line 102 connected to it. When the pixel unit 110 of a row outputs a gate voltage, the TFT of the pixel unit in this row is turned on, and the pixel units 110 in other rows are turned off, and each gate line sequentially outputs a gate voltage from top t...
