Abstract:
A display device comprises counter electrodes configured to be used as common electrodes for displaying and scan electrodes for touch sensing, a first scan circuit which scans gate lines, and a second scan circuit which scans the counter electrodes. In the display device, one frame period includes a write period for continuously scanning one screen and a touch sensing period existing between the write period and a write period in the next frame. The second scan circuit includes a shift register unit and a switch unit. The switch unit includes a seventh thin-film transistor which outputs a DC drive signal to an output node and an eighth thin-film transistor which outputs an AC drive signal to the output node. A second control signal for fixing the voltage of a third retention node to which the gate electrode of the seventh thin-film transistor is connected is inputted in the write period.

Claim (Index 4):
A display device comprising:\n a plurality of pixels; counter electrodes which are configured to be used as both common electrodes for displaying and scan electrodes for touch sensing; a first scan circuit which scans gate lines; and a second scan circuit which drives the counter electrodes, wherein: the display device is configured so that one frame period includes at least one write period for scanning the gate lines and at least one touch sensing period for scanning the scan electrodes, the second scan circuit includes a shift register unit and a switch unit, the first scan circuit and the second scan circuit include thin-film transistors, the switch unit includes a first thin-film transistor which outputs an alternate current drive signal to an output node in an ON state, a second thin-film transistor which outputs a direct current drive signal to the output node in the ON state, a third thin-film transistor which output a first control signal to the first thin-film transistor, and a fourth thin-film transistor which output a second control signal to the second thin-film transistor, the third thin-film transistor becomes the ON state by a third control signal which is output from the shift register unit and output the first control signal, the fourth thin-film transistor becomes the ON state by the third control signal and output the second control signal, the third control signal is input into a gate electrode of the third thin-transistor and the fourth thin-transistor, the first thin-film transistor becomes the ON state by the first control signal which is output from the third thin-film transistor in the touch sensing period, the first thin-film transistor becomes an OFF state by a fourth control signal which output from the shift register unit after the touch sensing period, and the second thin-film transistor becomes the ON state by the fourth signal after the touch sensing period.
