Bidirectional shift register
A bi-directional shift register includes N stages, wherein the mth stage among the N stages includes a node, an output end, first input circuit, second input circuit, and a shift register unit. N is a natural number greater than 1 and m is a natural number smaller than or equal to N. First control signal is measured on the node. The output end outputs an mth output signal. The first input circuit receives an m−1th output signal as a control signal and a power signal to accordingly generate an enabled first driving signal to the node in first period. The second input circuit receives an m+1th output signal as a control signal and a power signal to accordingly generate an enabled second driving signal to the node in second period. Controlled by the first control signal, the shift register unit generates an mth output signal in third period.
