Abstract
A display device including a panel having a gate driver is provided. The gate driver includes a multi-stage shift register. The N-th stage shift register includes a control module, a leakage compensation module, and an output module. The control module has a first terminal for receiving a first signal from the (N−M)-th stage shift register and a second terminal electrically connected to a node for transmitting a first signal to the node. The leakage compensation module has a third terminal electrically connected to the compensation voltage and a fourth terminal electrically connected to the node. The output module has a fifth terminal electrically connected to the node for receiving the first signal, and a sixth terminal for outputting a second signal of the N-th stage shift register for driving at least some parts of the pixel array. The compensation voltage charges the node during a touch sensing period.
