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

Claim 0:
1. A touch control circuit comprising:
a touch detection circuit configured to determine that a touch for a panel is occurred when a change in capacitance of each location of a touch electrode disposed in the panel is equal to or greater than a threshold;
an offset determination circuit configured to determine an offset location among locations at which the touch has occurred;
a threshold compensation ratio determination circuit configured to obtain a threshold compensation ratio for each distance based on the offset location; and
a final threshold determination circuit configured to determine a final threshold by compensating for the threshold based on the threshold compensation ratio,
wherein the touch detection circuit is further configured to determine whether the touch has occurred and a touch location of the panel based on the final threshold, and
wherein the touch detection circuit is further configured to differently set a threshold in a ground state of a display device and a threshold in a non-ground state of the display device.
