Abstract
Disclosed herein a touch display driving device for driving a touch panel including first and second touch panels, which includes a plurality of touch sensing circuits configured to receive a touch sensing signal from the touch panel, and a plurality of driving device pads connected to the touch panel and selectively connected to the touch sensing circuit, wherein the plurality of driving device pads are divided into first, second, and third driving device pads, and when the touch sensing signal is received from the first touch panel through the first and second driving device pads, the touch sensing circuit connected to the third driving device pad is turned off.
Claims19
A touch driving device comprising:
- a touch sensing circuit configured to receive a touch sensing signal from a touch panel including a first touch panel and a second touch panel;
- and
- a plurality of driving device pads connected to the touch panel and selectively connected to the touch sensing circuit,
- wherein the plurality of driving device pads are divided into a first driving device pad, a second driving device pad, and a third driving device pad, and
- when the touch sensing signal is received from the first touch panel through the first and second driving device pads, the touch sensing circuit connected to the third driving device pad is turned off.
A touch driving device comprising:
- a first touch sensing circuit configured to receive a touch sensing signal from a touch panel including a first touch panel and a second touch panel;
