GOA REPAIRABLE GOA CIRCUIT FOR FLAT PANEL DISPLAY AND DISPLAY DEVICE

摘要

The present invention relates to a repairable GOA circuit for a flat panel display and a display device including the repairable GOA circuit. The repairable GOA circuit includes a plurality of cascade-connected GOA units for controlling charging of the n-th stage horizontal scan line of the display area according to an n-th stage GOA unit, The n-th stage GOA unit is connected, and the n-th stage GOA unit includes a pull-up circuit, a pull-down circuit, a pull-down holding circuit, a pull-up control circuit, a boost capacitor and a first thin film transistor, The clock signal CK is input, the drain and the source are connected to the gate signal point and the n-th stage horizontal scan line, respectively; During the normal operation of the n-th stage GOA unit, at least one of a drain and a source of the first thin film transistor maintains a blocking state with the n-th stage GOA unit. The repairable GOA circuit allows the GOA circuit to have a certain redundancy, thereby improving the yield of the GOA display panel.
