Abstract:
A gate driver and a display device having an in-cell touch sensor using the gate driver are disclosed. The gate driver includes a shift register configured to sequentially supply gate pulses to gate lines of a display panel. The shift register includes an (N−1)th stage, where N is a positive integer equal to or greater than 2, configured to output an (N−1)th gate pulse, an Nth stage configured to output an Nth gate pulse, and a hold circuit configured to hold an output voltage of the (N−1)th stage during a predetermined time and supply the output voltage to the Nth stage.
