Abstract
An in-cell touch display device includes a first substrate, a plurality of common lines and a plurality of data lines. The common lines are disposed on the first substrate and extend along a first direction. The data lines are disposed on the first substrate and extend along a second direction. The common lines intersect and are insulated from the data lines. A plurality of touch sensing capacitors are formed at intersections of the common lines and the data lines to perform touch sensing.

An in-cell touch display device, comprising:
- a first substrate;
- a plurality of common lines, disposed on the first substrate, extending along a first direction;
- and
- a plurality of data lines, disposed on the first substrate, extending along a second direction, and insulated from the common lines;
- wherein, the common lines intersect the data lines, and a plurality of touch sensing capacitors are formed at intersections of the common lines and the data lines to perform touch sensing.
A driving method for an in-cell touch display device, the in-cell touch display device comprising a plurality of common lines extending along a first direction and a plurality of data lines extending along a second direction, the driving method comprising:
- in a display driving mode, transmitting display data on one of the data lines, and providing a common voltage to one of the common lines;
- and
- in a touch sensing mode, transmitting a first touch signal on the one of the data lines, and transmitting a second touch signal on the one of the common lines.
