Abstract
The present disclosure provides a built-in touch display device and a method for driving the same. Each of a plurality of shielding layers may be arranged between each of the plurality of data lines and each of a plurality of touch driving electrodes. A touch driving signal may be transmitted to the corresponding touch driving electrode when the plurality of first gate line groups corresponding to the common electrodes is in an ON state, and the transmitting of the touch driving signal to the corresponding touch driving electrode may be stopped when the plurality of second gate line groups corresponding to the touch driving electrodes is in an ON state.

14. A method for driving a built-in touch display device, comprising steps of:
-
counting a row number of a gate line being in the ON state currently; determining whether the gate line being in the ON state currently belongs to first gate line groups or second gate line groups based on the row number, wherein the first gate line groups correspond to common electrodes respectively, the second gate line groups correspond to touch driving electrodes respectively, and the common electrodes and the touch driving electrodes are arranged to be spaced apart from each other on a same layer and in an alternate manner; and controlling a touch chip to transmit a touch driving signal to a corresponding touch driving signal transmission line when the gate line being in the ON state currently belongs to the first gate line groups, and controlling the touch chip to stop transmitting the touch driving signal to the corresponding touch driving signal transmission line when the gate line being in the ON state currently belongs to the second gate line groups. - View Dependent Claims (15, 16)
