The invention provides a drive circuit and a drive method for a double-gate pixel structure, a display panel and a display device. The drive circuit for the double-gate pixel structure comprises a plurality of stages of array substrate row drive units, wherein the same row pixel unit is driven by gate drive signals output by two stages of the array substrate row drive units in a time-sharing manner. According to the drive circuit for the double-gate pixel structure, the same row pixel unit is driven by gate drive signals output by two stages of the array substrate row drive units in the time-sharing manner, so that when the array is designed into a Z-reversal mode and adopts a double-gate mode, coverage for repairing does not generate different stray capacitances in an odd or even line even under a 1or 2-line pre-charging mode, so that pixel voltage of odd and even lines is prevented from difference to eliminate a color error problem; meanwhile, product power consumption is reduced, and the drive circuit has a pixel dead pixel repairing function.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a driving circuit, a method, a display panel and a display device of a double-gate pixel structure. Background technique [0002] TN (Twisted Nematic, twisted nematic phase) type LCD (Liquid Crystal Display, liquid crystal display) pixel repair point design is to keep the overlay (cover) between the pixel electrode and the gate line, and the pixel electrode is welded by welding during repair. Shorted together with grid wire. However, if the array is designed as Z-inversion and double-gate mode is used, the cover used for repair will generate different parasitic capacitances in the odd and even lines in the 1&2 line pre-charging mode, resulting in differences in the pixel voltage of the odd and even lines, resulting in color The phenomenon of partiality will affect the display effect. The 1&2 precharge of the normal dual gate mode can offset the phenomenon of color shift becaus...
