Abstract

The invention provides a liquid crystal display panel and a driving method thereof. The liquid crystal display panel is characterized in that a gate electrode driving unit is used for inputting scanning signals according to a first preset order, and under the first preset order, the gate electrode driving unit inputs the scanning signals to multiple scanning lines in each row at intervals; and a source electrode driving unit is used for inputting gray scale voltage according to a second preset order, and under the second preset order, the source electrode driving unit inputs the gray scale voltage to multiple data cables stretching in column direction at intervals. The liquid crystal display panel prevents the charging efficiency of a pixel unit from inconformity which is caused by voltage drop due to the existing of signal lines, and improves the image display effect of the liquid crystal display panel.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a driving method thereof. 【Background technique】 [0002] With the continuous popularization of liquid crystal display panels, the requirements for display quality of liquid crystal display panels are getting higher and higher. [0003] see figure 1 , figure 1 It is a schematic diagram of a pixel structure of a liquid crystal display panel in the prior art. The above-mentioned liquid crystal display panel includes 2m data lines D'1~D'2m (data line), 2k scanning lines G'1~G'2k (Gate line ), the gate driver chip 11 and the source driver chip 12, the above-mentioned data lines and scan lines are arranged crosswise, the gate driver chip 11 is connected to the scan lines, the source driver chip 12 is connected to the data lines, and the two data lines adjacent to each other A pixel unit (not labeled) is formed at the crossing area...
