Patent ID: 8890822

Claim:
A method for controlling operations of a touch panel, the touch panel comprising a display layer and a sensing layer, a plurality of gate lines formed on the display layer, and a plurality of touch sensors formed on the sensing layer, the method comprising: synchronizing timing of the plurality of gate lines and timing of the plurality of touch sensors; determining whether polarities of common voltages of the display layer are consistent when driving signals are outputted to a first gate line and a second gate line, the second gate line following the first gate line; when the polarities are consistent, outputting at least one driving pulse to a touch sensor of the plurality of touch sensors after image data corresponding to the second gate line is transmitted to the display layer; and determining whether polarities of common voltages of the display layer are consistent when driving signals are outputted to the second gate line and a third gate line, the third gate line following the second gate line; wherein when the polarities of the common voltages of the display layer are inconsistent when the driving signals are outputted to the second gate line and the third gate line, no driving pulse is outputted to the plurality of touch sensors after image data corresponding to the third gate line is transmitted to the display layer.
