Abstract
A gate driving circuit including a controller for providing a first carry signal to a control node, a first pull-up portion for outputting a first clock signal as a first gate signal in accordance with a signal provided to the control node, and a second pull-up portion for outputting a second clock signal with a phase that is different from the first clock signal as a second gate signal in accordance with the signal provided to the control node.
Claims20
A gate driving circuit comprising:
- a controller for providing a first carry signal to a control node;
- a first pull-up portion for outputting a first clock signal as a first gate signal in accordance with a signal provided to the control node;
- and
- a second pull-up portion for outputting a second clock signal with a phase that is different from the first clock signal as a second gate signal in accordance with the signal provided to the control node.
A gate driving circuit comprising:
- a plurality of stages connected to each other in series, each of the stages being configured to output two gate signals,
- wherein each of the stages comprises:
- a controller for providing a first carry signal from a previous one of the stages to a control node;
- a first pull-up portion for outputting a first clock signal as a first gate signal in accordance with a signal provided to the control node;
- a second pull-up portion for outputting a second clock signal having a phase that is different from a phase of the first clock signal as a second gate signal in accordance with the signal provided to the control node;
- and
- a carry portion for outputting the second clock signal as a second carry signal in accordance with the signal provided to the control node.
A display device comprising:
- a display panel comprising a plurality of pixels connected to first to third gate lines adjacent one another;
- a first gate driving circuit on a first side of the display panel and comprising a first stage for outputting first and second gate signals having phases that are different from each other;
- and
- a second gate driving circuit on a second side of the display panel that is opposite the first side of the display panel, and comprising a second stage for outputting third and fourth gate signals having phases that are different from each other,
- wherein the first stage is configured to provide the first gate signal to a first side of the second gate line,
- wherein the second stage is configured to provide the fourth gate signal to a second side of the second gate line,
- wherein the first stage is configured to provide the second gate signal to a first side of the third gate line, and
- wherein the second stage is configured to provide the third gate signal to a second side of the first gate line.
