Abstract
A gate driving circuit includes a plurality of stages. Adjacent two stages from among the plurality of stages constitute a stage pair. The adjacent two stages in the stage pair include switching elements connected with each other. When a carry signal of an N-th stage in the stage pair has a defect, the N-th stage is configured to output a carry signal of an (N+1)-th stage in the stage pair. N is a positive integer. When a defect has occurred at a carry signal of a stage in a stage pair, the carry signal of the stage having the defect may be repaired by a carry signal of another stage in the stage pair.
Claims19
A gate driving circuit comprising a plurality of stages,
- wherein adjacent two stages from among the plurality of stages constitute a stage pair,
- wherein the adjacent two stages in the stage pair include switching elements that are connected with each other,
- wherein when a carry signal of an N-th stage in the stage pair has a defect, the N-th stage is configured to output a carry signal of an (N+1)-th stage in the stage pair, and
- wherein N is a positive integer.
A display apparatus comprising:
- a display panel configured to display an image;
- a gate driver configured to output a gate signal to the display panel;
- and
- a data driver configured to output a data voltage to the display panel;
- wherein the gate driver comprises a plurality of stages,
- wherein adjacent two stages from among the plurality of stages in the gate driver constitute a stage pair,
- wherein the adjacent two stages in the stage pair include switching elements connected with each other,
- wherein when a carry signal of an N-th stage in the stage pair has a defect, the N-th stage is configured to output a carry signal of an (N+1)-th stage in the stage pair, and
- wherein N is a positive integer.
