Problems solved by technology
On the one hand, this disadvantage is that the signal frequency is too high, which increases the power consumption on the data line; on the other hand, the charging time of the HSD architecture pixel is very short, and the resistance-capacitance delay effect (RC Delay) of signal switching on the data line will further increase. Affects the charging of pixels, which is not conducive to the improvement of display quality, and when the resolution of LCD panel increases, this problem will be more serious

The invention provides a driving method for a liquid crystal display panel. The driving method comprises the following steps: providing a plurality of data lines, a plurality of gate lines (Gate1-Gatem), and a plurality of pixels (P); each pixel is connected with one data line and one gate line, and the polarity of each pixel unit is opposite to that of pixel units adjacent to the pixel unit in upper, lower, left and right directions; the gate lines of the pixels with first polarity are sequentially conducted corresponding to driving voltage to complete half-frame signal writing; the gate lines of the pixels with second polarity are sequentially conducted corresponding to the driving voltage to complete other half-frame signal writing, the first polarity is opposite to the second polarity, and m is multiples of 4. Through the driving method for the liquid crystal display panel, the polarity of the driving voltage only needs to be switched twice within one-frame time of signals of the data lines, so that the power consumption of the whole panel is reduced, the charging status of the pixels is improved, and the display quality is improved.
Description
Technical field [0001] The invention relates to the field of liquid crystal display panels, and in particular to a method for driving a liquid crystal display panel. Background technique [0002] TFT-LCD (Thin Film transistor liquid crystal display) has the characteristics of small size, low power consumption, and no radiation, and it occupies a dominant position in the current flat panel display market. The TFT-LCD mainly includes an array substrate and a color film substrate that are aligned together and sandwich the liquid crystal between them. The array substrate is formed with a gate line (Gate Line) for providing scanning signals and a data line (Data Line) for providing data signals. , The pixel electrode and thin film transistor forming the pixel point, each pixel electrode is controlled by the thin film transistor. When the thin film transistor is turned on, the pixel electrode is charged during the on time. After the thin film transistor is turned off, the pixel electr...
