Abstract

The disclosure provides a method and a device for decreasing a leakage current of an in-cell touch liquid crystal panel. The method includes: outputting a signal after adjusting a voltage by the data line during a time period of scanning a touch signal according to a voltage on the data line connected to the pixel and a signal inputted to a common electrode of the pixel for scanning the touch signal, so as to decrease a drain source voltage of a thin film transistor in the pixel. According the method and the device, it is capable of decreasing the leakage current of the in-cell touch liquid crystal panel effectively.
