Abstract
The invention provides a gate-in-panel display device capable of preventing deterioration of thin-film transistors during pause drive, as well as a method for driving the same.At the end of a drive period, an active clear signal is provided to thin-film transistors in unit circuits, each thin-film transistor being connected to either a first or second node at a gate terminal, thereby bringing the thin-film transistors into ON state. As a result, the voltages of the first and second nodes are set to a reference voltage. Thus, even if a pause period lasts for a long period of time, the gate terminals of the thin-film transistors are not subjected to sustained voltage application, leading to no threshold voltage shifts.
