Abstract:
1. A driving apparatus for a display device having a plurality of pixels each having a switching element, comprising: a gate line connected to the switching element; a gate driver to apply first to third voltages to the gate line through an output end; a first voltage generator to generate the first and third voltages; and a second voltage generator to generate the second voltage; a first transistor comprising an input terminal configured to receive the first voltage, and an output terminal connected to the output end of the gate driver; a second transistor comprising an input terminal configured to receive the second voltage, and an output terminal; a third transistor comprising an input terminal connected to the output terminal of the second transistor, and an output terminal connected to the output end of the gate driver; a fourth transistor comprising an input terminal configured to receive the first voltage, and an output terminal connected to the output end of the gate driver, wherein the first and second voltages turn on the switching element, and the third voltage turns off the switching element, and the second voltage is less than the first voltage.
