DRIVING CIRCUIT FOR DISPLAY PANEL AND HIGH VOLTAGE TOLERANT CIRCUIT

摘要

A driving circuit for display panel is provided. Wherein, a first and a second power supply circuits produce a first and a second supply voltages. The electric charge provided by the second power supply circuit is less than that provided by the first power supply circuit. A plurality of drivers include a plurality of first power input terminals and a plurality of second power input terminals. The first power input terminals are coupled to the firs power supply circuit and receives the first supply voltage. The second power input terminals are coupled to the second power supply circuit and receives the second supply voltage. The drivers increase the voltage levels of a plurality of gate signals in a voltage rising period according to the first supply voltage. The drivers hold the voltage levels of gate signals in a voltage holding period according to the second supply voltage.
