Abstract
In a display driving circuit, odd-stage shift registers (SRs) are cascaded; and even-stage SRs are cascaded. The SRs support dual direction shifting. Each SR includes: first, second, third, and fourth transistors. The first transistor is coupled to a forward scan start signal from a third transistor of a former second SR, coupled to an output signal from the former second SR and coupled to a node. The second transistor is coupled to a reverse scan start signal from a fourth transistor of a next second SR, coupled to an output signal from the next second SR and coupled to the node. The third transistor is coupled to a forward operation voltage and coupled to the node, and further outputs a forward scan start signal. The fourth transistor is coupled to a reverse operation voltage and coupled to the node, and further outputs a reverse scan start signal.
