A method for controlling operations of a touch panel includes synchronizing timing of a plurality of gate lines and timing of a plurality of touch sensors; determining whether polarities of common voltages of a 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; and if 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.

Method for controlling operations of a touch panel

An exemplary method for determining a touch point includes the following steps of: performing a first operation to determine whether a detected result of a first touch detection point exceeds a first threshold; performing a second operation to determine whether all detected results of multiple second touch detection points are no more than the detection result of the first touch detection point, the second touch detection points neighboring with the first touch detection point; performing a third operation to determine whether a sum of detected results of multiple third touch detection points exceeds a second threshold, the third touch detection points neighboring with the first touch detection point; and determining the first touch detection point as the touch point is being touched if the determine results of the first through third operations are all true.
