摘要

The present invention provides a circuit structure of a liquid crystal panel and a driving method of a liquid crystal panel. The circuit structure of a liquid crystal panel comprises: a data driving control chip having n data signal output lines, a column driving scan chip, M triggers, M liquid crystal pixel array areas corresponding to the M triggers, a dot clock signal (CLK) and a common voltage (VCOM); each of the liquid crystal pixel array areas comprises: (n×N) liquid crystal pixels, N scan signal lines, and n liquid crystal pixel data signal lines; By sequentially triggering the triggers, the liquid crystal pixels of the M liquid crystal pixel array areas are sequentially charged without interferes with one another. The present invention also provides a corresponding driving method of a liquid crystal panel. The circuit structure of the liquid crystal panel and the driving method of the liquid crystal panel are capable of reducing the amount of the data signal output lines of the data driving control chip. Meanwhile, the color shift caused by the varying charges to the left, right areas and the middle areas of the liquid crystal panel can be solved.
