Title: DATA VOLTAGE ADJUSTMENT METHOD AND DEVICE OF LIQUID CRYSTAL DISPLAY PANEL
Abstract:
A data voltage adjustment method of a liquid crystal display panel is disclosed, comprising: obtaining a total amount of data voltage change on all data lines in the liquid crystal display panel (101); according to a horizontal crosstalk indicator of the liquid crystal display panel, calculating a maximum amount of data voltage change corresponding to the horizontal crosstalk indicator (102); determining whether the absolute value of the total amount of data voltage change is greater than the absolute value of the maximum amount of data voltage change corresponding to the horizontal crosstalk indicator (103); and if so, according to the total amount of data voltage change, performing data voltage adjustment on the data lines in the liquid crystal panel (104)in which data voltage changes. A data voltage adjustment device of a liquid crystal display panel is also disclosed. The data voltage adjustment method of a liquid crystal display panel can reduce the impact of data voltage jumps on a common voltage of the liquid crystal display panel, avoiding horizontal crosstalk.
