Embodiment Construction

[0028] In the present invention, the liquid crystal display adopts a double-gate structure, and an interlaced scanning method is adopted during row scanning, that is, in a frame, the pixels on the odd-numbered grid lines are first driven, and then the pixels on the even-numbered grid lines are driven. Wherein, during the process of driving the pixels of the odd-numbered gate lines and the process of driving the pixels of the even-numbered gate lines, two kinds of data driving signals with opposite polarities are respectively output.

[0029] A liquid crystal display driving method according to the present invention, said liquid crystal display driving method comprises: first driving the pixels connected to the odd-numbered gate lines row by row, and then driving the pixels connected to the even-numbered row gate lines row by row, and so on ;In the same frame, the polarities of the driving signals connected to the pixels on the odd-numbered gate lines are the same, the polaritie...

Abstract

The invention discloses a liquid crystal display driving method. The method includes the steps of driving pixels connected to gate lines in odd-number lines line by line, then, driving pixels connected to gate lines in even-number lines line by line, and so on, or the method includes the steps of driving pixels connected to gate lines in even-number lines line by line firstly, then, driving pixels connected to gate lines in odd-number lines line by line, and so on. Correspondingly, the invention further discloses a liquid crystal display. According to the liquid crystal display and the driving method thereof, Z-reversal of double-gate pixels can be achieved, and power consumption of the liquid crystal display is reduced effectively under the precondition that high-quality images are guaranteed.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal display and a driving method thereof. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) includes a gate driving circuit, a data driving circuit and a pixel area. Wherein, the gate drive circuit includes a plurality of gate lines, which sequentially generate gate drive signals, and the data drive circuit includes a plurality of data lines, which are used to generate data drive signals, each gate line is a straight line parallel to each other, and each data line are straight lines parallel to each other; the pixels in the pixel area are formed by interlacing gate lines and data lines, and are driven by gate drive signals generated by corresponding gate lines to receive data drive signals generated by corresponding data lines. [0003] At present, in order to reduce costs, the dual gate (Dual gate) pixel structure is more and m...
