Patent ID: 8866859

Claim:
A scan driver, comprising: a first scan driving block, the first scan driving block receiving a first clock signal, a second clock signal, an entire clock signal, and a simultaneous light emitting control signal, the first scan driving block outputting the second clock signal to a first output terminal according to an input signal, in synchronization with the first clock signal; and a second scan driving block, the second scan driving block receiving the first clock signal, the second clock signal, the entire clock signal, and the simultaneous light emitting control signal, the second scan driving block receiving the output signal of the first scan driving block and outputting the first clock signal according to the output signal of the first scan driving block to a second output terminal, in synchronization with the second clock signal, wherein: the first scan driving block and the second scan driving block simultaneously output the entire clock signal according to a level of the simultaneous light emission control signal, and a first input terminal of the first scan driving block is input with the first clock signal, a second input terminal of the first scan driving block is input with the second clock signal, a first input terminal of the second scan driving block is input with the second clock signal, and a second input terminal of the second scan driving block is input with the first clock signal.
