发明名称 Voltage generating circuit having a discharge part and display apparatus having the voltage generating circuit
摘要 A voltage generating circuit includes a voltage dividing part connected between a main voltage source and a ground configured to divide a main voltage into a plurality of driving voltages and output the plurality of driving voltages, a delay part connected between a driving voltage source and the ground, and configured to delay a driving voltage by a predetermined period and apply the driving voltage to an input terminal of a driver circuit, and a discharge part connected between the voltage dividing part and the delay part, and configured to discharge a voltage charged in the delay part to a ground when the driving voltage is blocked. The discharge part comprises an amplifier, an inverting input of the amplifier being connected to the driving voltage source and a non-inverting input of the amplifier being connected to an output terminal of the delay part.
