gate drive unit

Abstract

Provided is a gate driving unit including: a plurality of stages configured to be sequentially activated to generate a gate signal; and a plurality of repair blocks having a smaller size than the corresponding stages and configured to Repair the defects of the said class. Each of the repair blocks is disposed adjacent to two or more stages so as to be configured to repair defects in the two or more stages.

Description

technical field [0001] The disclosure herein relates generally to flat panel displays. More particularly, the present disclosure relates to a gate driving unit for a flat panel display device. Background technique [0002] Generally, a flat panel display device includes: a display panel having a plurality of pixels to display images; a gate driving unit providing gate signals to the plurality of pixels; and a data driving unit providing data voltages to the plurality of pixels. [0003] The gate driving unit generates gate signals and provides the generated gate signals to pixels. The data driving unit generates data voltages and provides the generated data voltages to pixels. In response to the gate signal, the pixels receive data voltages to display images. [0004] The gate driving unit includes a plurality of stages connected in cascade. Each stage includes a plurality of transistors connected to each other to output a gate voltage to a corresponding gate line. Acco...

Problems solved by technology

[0005] However, when the stage of the gate driving unit is damaged, a normal gate signal is not generated

As a result, the display device cannot be driven normally
