Abstract
The present invention relates to a scan driving circuit, which comprises a decoding circuit, a plurality of level-shift driving circuits, and a control circuit. The decoding circuit produces a decoding signal according to a decoding control signal. The plurality of level-shift driving circuits are coupled to the decoding circuit and produce scan signal sequentially according to the decoding signal. The control circuit is coupled to the plurality of level-shift driving circuit. The control circuit produces a first control signal and a second control signal according to the decoding control signal and transmits the first and second control signals to the plurality of level-shift driving circuits for controlling their turning on and off. Accordingly, by means of the control circuit according to the present invention, the circuit area of each level-shift driving circuit can be reduced, and thus the cost can be reduced as well.
