Abstract:
A driving circuit. The driving circuit includes a plurality of scan shift register cells, a pair of complementary clock signal lines, and a horizontal start signal generator. Each scan shift register cell comprises a bidirectional circuit, a shift register coupled to the bidirectional circuit, a transmission gate coupled to the shift register, and a data line coupled to the transmission gate. The complementary clock signal lines are coupled to the shift registers. The horizontal start signal generator provides a horizontal start signal to the bidirectional circuits in the first and a subsequent scan shift register cells. The shift register in each scan shift register cell provides an output signal to the bidirectional circuit in the next scan shift register cell. The bidirectional circuit in each scan shift register cell also receives the output signal from the shift register in the next scan shift register cell.

Each pair of control lines is respectively electrically coupled to the first and second switches of a corresponding channel of each multiplexer. Each pair of control signals are configured such that a time turning off one of the first and second switches is earlier than that turning off the other switch.
