摘要
A shift register, a bidirectional shift register apparatus and a liquid crystal display panel using the same are provided. The shift register includes a precharge unit, a pull up unit, and a pull down unit. The precharge unit receives outputs of a previous two-stage of shift register and a next two-stage of shift register both corresponding to the shift register to thereby generate a precharge signal. The pull up unit is coupled to the precharge unit, and receives the precharge signal and a first input clock signal to thereby output a scan signal. The pull down unit is coupled to the precharge unit and the pull up unit, and receives the precharge signal, the first input clock signal and a second input clock signal to control a voltage level of the scan signal, where the first input clock signal and the second input clock signal are inverted in phase.
