<p>A bidirectional shift register includes first, second, third and fourth control signal bus lines for providing first, second, third and fourth control signals (Bi1, Bi2, Bi3, Bi4), respectively, and a plurality of shift register stages (302) electrically coupled in serial, each shift register stage (302) having a first input node (Bi) and a second input node (XBi), where the plurality of shift register stages (302) is grouped into a first section (321) and a second section (322), wherein the first (Bi) and second (XBi) input nodes of each shift register stage (302) in the first section (321) are electrically coupled to the first and second control signal bus lines for receiving the first (Bi1) and second (Bi2) control signals, respectively, and the first (Bi) and second (XBi) input nodes of each shift register stage (302) in the second section (322) are electrically coupled to the third and fourth control signal bus lines for receiving the third (Bi3) and fourth (Bi4) control signals, respectively.</p> |
