Driving circuit for a display panel and liquid crystal display device using the same
Abstract:
A driving circuit is provided to reduce threshold voltage shifting of a driving switch thereof, and includes a capacitor, a pre-charging switch, a scanning switch, a driving switch, three stabilizing switches, and a light emitting device. A gate electrode of the pre-charging switch receives a first control signal, a drain electrode thereof receives a second control signal, and a source electrode thereof is connected to the capacitor, so as to pre-charge the capacitor to switch on the driving switch. The capacitor then discharges through the driving switch. When the driving circuit reaches a stable state, the driving switch drives the light emitting device to emit light.
