Abstract
The invention provides a gate driving circuit and a display device. The gate driving circuit is configured to drive a display panel of the display device, and includes shift registers and at least a dummy shift register. The shift registers are respectively configured to generate and output scan signals to scan lines of the display panel, the dummy shift register is configured to generate a dummy scan signal before the scan signals are generated. The dummy scan signal and the scan signals are sequentially generated.
Claims20
A gate driving circuit for driving a display panel, the gate driving circuit comprising:
- 1st to Nth stage first shift registers configured to respectively generate and output 1st to Nth stage first scan signals to a plurality of first scan lines of the display panel;
- and
- one or more first dummy shift registers configured to respectively generate and output one or more first dummy scan signals before the first scan signals are generated;
- wherein the one or more first dummy scan signals and the first scan signals are sequentially outputted, and N is an integer.
A display device, comprising:
- a display panel having opposite first and second sides;
- a driving circuit configured to drive the display panel, the driving circuit comprising:
- 1st to Nth stage first shift registers configured to respectively generate and output 1st to Nth stage first scan signals to a plurality of first scan signals of the display panel;
- one or more first dummy shift registers configured to respectively generate and output one or more first dummy scan signals before the first scan signals are generated;
- 1st to Nth stage second shift registers configured to respectively generate and output 1st to Nth stage second scan signals to a plurality of second scan signals of the display panel;
- and
- one or more second dummy shift registers configured to respectively generate and output one or more second dummy scan signals before the second scan signals are generated;
- wherein the one or more first dummy scan signals and the first scan signals are sequentially outputted, the one or more second dummy scan signals and the second scan signals are sequentially outputted, the one or more second dummy scan signals respectively have substantially the same time sequences as those of the one or more first dummy scan signals, the second scan signals respectively have substantially the same time sequences as those of the first scan signals, and N is an integer.
