Abstract:
A scan driving circuit formed on an active matrix liquid crystal display panel, comprising:a scan line; a first control signal line for inputting a first control signal from outside of said panel; a first transmission circuit with a signal input port connected to said first control signal line, a signal output port connected to said scan line, and at least one control signal input port for switching said first transmission circuit; an unselect voltage signal line for providing an unselect voltage signal; a second transmission circuit with a signal input port connected to said unselect voltage signal line, a signal output port connected to said scan line, and at least one control signal input port for switching said second transmission circuit; and Z pairs of complementary second control signal lines connected respectively to said control signal input ports of said first and second transmission circuits for inputting Z pairs of complementary second control signals to determine whether or not said scan line is connected to said first control signal line or unselect voltage signal line.
