Abstract:
A scan driving circuit includes a plurality of stages. Each stage receives three of four clocks that may be sequentially generated, receives and delays an input signal through an input terminal, and outputs an output signal through an output terminal. The input terminal of each stage is connected to the output terminal of a previous one of the stages. Each stage includes a transistor, a switch section, and a storage section. The transistor turns off/on a connection of the input terminal according to a second clock. The switch section transfers a first voltage to the output terminal according to a first clock and prevents the first voltage from being transferred to the output terminal according to the input signal. The storage section maintains a voltage of the output terminal for a predetermined time and transfers a voltage of a third clock to the output terminal according to the input signal.
