Patent ID: 7830352

Claim:
A driving circuit for use in a flat panel display, comprising: a plurality of scan shift register cells, each having a bidirectional circuit controlled by a direction control signal, and a shift register coupled to the bidirectional circuit, wherein at least one of the scan shift register cells comprises a transmission gate coupled to the shift register and adapted to receive an RGB signal, and a data line coupled to the transmission gate; a pair of complementary clock signal lines coupled to the shift registers in the scan shift register cells correspondingly; and a horizontal start signal generator adapted to provide a horizontal start signal simultaneously to the bidirectional circuits in a first and a second scan shift register cells, in which the second shift register cell is next to the first shift register cell; wherein the shift register in each scan shift register cell is adapted to provide an output signal to the bidirectional circuit in the next scan shift register cell, and the bidirectional circuit in each scan shift register cell is adapted to receive the output signal from the shift register in the next scan shift register cell.
