Problems solved by technology

[0006] Because of the aforementioned noise, capacitive-based touch sensors may not correctly detect a touch, the location of a touch, and / or the duration of a touch, and may malfunction as a result, and thus, the touch sensor may be so poorly operated that reliance on System software for correct detection of touches, locations of touches and / or duration of touches may also malfunction as a result, and user commands to this software based on touches may not be properly obeyed

Abstract

A method of driving a touch display panel includes sequentially providing gate signals to a plurality of gate lines, outputting data signals to a plurality of data lines, the data lines being disposed on the first surface and crossing the gate lines, and reading out a first sensing signal through a plurality of sensing lines in response to the gate signals. The gate lines are disposed on a first surface of a base substrate, the touch display panel including the base substrate. The data signals are synchronized with the gate signals. The sensing line is disposed on a second surface of the base substrate, the second surface being opposite to the first surface.

Description

technical field [0001] The present disclosure relates to a method of driving a touch-responsive display panel and a touch-responsive display device configured to perform the method for driving the touch-responsive display panel. More particularly, example embodiments relate to a method of driving a touch display panel using a gate signal. Background technique [0002] In a recently developed touch display device, a conductive material such as a finger touches the touch display device, and then the capacitance of the touch sensor is changed, so a touch position can be detected through a change in the capacitance of the touch sensor. [0003] For example, such a touch display device may include a first substrate and a second substrate spaced apart therefrom. The first substrate includes gate lines, data lines, switching elements electrically connected to the gate lines and the data lines, and pixel electrodes electrically connected to the switching elements. The second subst...
