Assignee: LG DISPLAY CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A method for driving a display device having a touch sensor, the method comprising:
applying a touch driving signal to touch electrodes of a display panel and amplifying charges flowing from the touch electrodes based on an amplifier reset signal so as to generate an amplifier output voltage; and
differentially adjusting a toggle timing of the amplifier reset signal depending on positions of the touch electrodes, and
differentially adjusting a voltage amplitude of the touch driving signal depending on the positions of the touch electrodes so as to differentially control a level of the amplifier output voltage depending on the positions of the touch electrodes,
wherein the differentially adjusting the toggle timing of the amplifier reset signal differentially adjusts an on-start timing of the amplifier reset signal and an on duty of the amplifier reset signal depending on the positions of the touch electrodes.
