Abstract: 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.

Abstract: A display device can include a plurality of sub pixels disposed on a substrate; a first driver disposed in each of the plurality of sub pixels, the first driver being configured to generate a first driving current for a normal mode in which an image is displayed in a luminance range equal to or lower than a predetermined luminance; a second driver disposed in each of the plurality of sub pixels, the second driver being configured to generate a second driving current for a high luminance mode in which the luminance range is higher than the predetermined luminance; and a light emitting diode. Also, the light emitting diode is configured to receive the first driving current in the normal mode, and receive a sum of the first driving current and the second driving current in the high luminance mode.
