Patent ID: 8466905

Claim:
A scan driving apparatus, comprising: a first driving apparatus connected to a plurality of scan lines; and a second driving apparatus connected to the plurality of scan lines, wherein, when one of the first driving apparatus and the second driving apparatus is in a scan enable state such that the plurality of scan lines are applied with a scan signal, the other of the first driving apparatus and the second driving apparatus is in a floating state such that an output terminal is floated, wherein at least one of the first driving apparatus and the second driving apparatus includes a plurality of scan driving blocks respectively connected to the plurality of scan lines; the plurality of scan driving blocks including: a first scan driving block for outputting a second clock signal to a first output terminal according to an input signal in synchronization with a first clock signal, and for outputting a first voltage to the first output terminal according to a third clock signal; a second scan driving block for outputting the third clock signal to a second output terminal in synchronization with a second clock signal according to the second clock signal output by the first scan driving block, and for outputting the first voltage to the second output terminal according to the first clock signal; and a third scan driving block for outputting the first clock signal to a third output terminal synchronization with the third clock signal according to the third clock signal output by the second scan driving block, and for outputting the first voltage to the third output terminal according to the second clock signal; wherein the first, second and third output terminals are floated from the first, second and third scan driving blocks according to a floating signal.
