Driving circuit for display apparatus
Abstract:
A driving circuit includes a plurality of stages driven in response to a start signal. Each normal stage outputs a gate signal and a carry signal, increases an electric potential of a node in response to a previous carry signal of a previous stage, and decreases the gate signal to a first voltage in response to a carry signal from a next stage. Each stage applies a second voltage lower than the first voltage to the node in response to receipt of a carry signal from a second next stage. A first dummy stage outputs a first dummy carry signal to the last two normal stages in response to a last carry signal from the last normal stage and the start signal, and a second dummy stage outputs a second dummy carry signal to the last normal stage in response to the first dummy carry signal and the start signal.
