Abstract
The selecting circuit includes first and second switch units. The first switch unit includes a first control terminal, a first input terminal, and a first output terminal. The second switch unit includes a second control terminal, a second input terminal, and a second output terminal. The first output terminal connects to the second output terminal, the first input terminal connects to an output terminal of a first-stage of driving units, the second input terminal connects to an output terminal of a last-stage of the driving units. A first control signal inputted from the first control terminal controls the first switch unit to be turned on or off, a second control signal inputted from the second control terminal controls the second switch unit to be turned on or off, to selectively output an output signal of first or second output terminals based on an output sequence of the scan driving signal.
