SCAN DRIVER CIRCUIT AND DRIVING METHOD FOR THE SCAN DRIVER CIRCUIT

摘要

A scan driving circuit includes a plurality of stages, each having a shift register and a scan signal output unit. The shift register has a first node to receive a first driving voltage according to a control signal and a second node to receive the first driving voltage according to a reset signal. The scan signal output unit outputs scan signals to respective scan lines. The scan signal output unit has a plurality of clock switches controlled according to a voltage of the first node and a plurality of switches controlled according to a voltage of the second node. The clock switches sequentially output clock signals to respective third nodes, which are connected to respective scan lines. The switches output a second driving voltage to the third nodes.
