A display device and a driving method thereof. While a turn-on gate signal is being supplied to a first gate line, a dummy voltage is supplied to a first type data line, and a first image frame voltage for expressing a first image frame line is supplied to a second type data line. The readability of an image frame is improved.

Display device and driving method

An organic light-emitting display device having a pixel structure able to significantly improve threshold voltage compensation capability and range by compensating for a loss in a threshold voltage that would occur during operation.

Organic light emitting display device having compensation pixel structure

A gate driving module and a gate-in-panel comprising a first pull-up TFT having a terminal connected to a gate driving signal generator and another terminal connected to an end of a first gate line, a first pull-down TFT having a terminal connected to the end of the first gate line and another terminal connected to a low-level voltage terminal, and a second pull-up TFT having a terminal connected to the gate driving signal generator and another terminal connected to another end opposite to the end of the first gate line, wherein the first pull-down TFT is turned off when the first pull-up TFT and the second pull-up TFT are turned on, and the first pull-down TFT is turned on when the first pull-up TFT and the second pull-up TFT are turned off.
