SHIFT REGISTER AND FLAT PANEL DISPLAY DEVICE INCLUDING THE SAME

摘要

Disclosed are a shift register and a flat panel display device. The shift register includes a plurality of stages that supply a gate-on voltage pulse to a plurality of gate lines formed in a display panel. Each of the stages includes a pull-up transistor configured to supply one of a plurality of clock signals to an output node according to a voltage of a first node, a pull-down transistor configured to supply a gate-off voltage to the output node according to a voltage of a second node, a node controller configured to control the voltages of the first and second nodes on the basis of a gate start signal, and a switching unit connected to at least two gate lines adjacent to the output node, and configured to sequentially supply gate-on voltage pulses having different pulse widths to the at least two adjacent gate lines using the clock signal.
