Abstract
The present disclosure provides a display device including a display panel and a scan driver. The display panel displays an image. The scan driver includes a scan signal generation circuit disposed on one side of the display panel, and an emission signal generation circuit disposed on the other side of the display panel. The emission signal generation circuit outputs an emission signal having at least two Logic High sections in response to an external clock signal and a first scan signal output from the scan signal generation circuit.
Claims17
A display device comprising:
- a display panel displaying an image at a display area;
- and
- a scan driver comprising a scan signal generation circuit on a first side of the display panel and an emission signal generation circuit on a second side of the display panel, the second side being opposite to the first side in a direction along which a scan line travels,
- wherein the scan signal generation circuit includes first and second shift register circuits sequentially generating first and second scan signals based on first and second clock signals, and the first shift register circuit outputs the first scan signal to the scan line on the first side, and
- wherein the emission signal generation circuit outputs an emission signal having at least two Logic High sections to the display area of the display panel in response to an external clock signal and receives the first scan signal directly from the scan line travelling through the display area of the on the second side.
A scan driver for a display panel comprising:
- a scan signal generation circuit on a first side of the display panel having a display area;
- and
- an emission signal generation circuit on a second side of the display panel, the second side being opposite to the first side in a direction along which a scan line travels,
- wherein the scan signal generation circuit includes first and second shift register circuits sequentially generating first and second scan signals based on first and second clock signals, and the first shift register circuit outputs the first scan signal to the scan line on the first side, and
- wherein the emission signal generation circuit outputs an emission signal having at least two Logic High sections to the display area of the display panel in response to an external
- clock signal and receives the first scan signal directly from the scan line travelling through the display area of the on the second side.
A method of driving a display device which includes a display panel for displaying an image at a display area and a scan driver, wherein the scan driver includes a scan signal generation circuit having first and second shift register circuits disposed on a first side of the display panel and an emission signal generation circuit disposed on a second side of the display panel, and wherein the second side is opposite to the first side in a direction along which a scan line travels, the first and second shift register circuits sequentially generate first and scan signals based on first and second clock signals, and the first shift register circuit outputs the first scan signal to the scan line on the first side, the method comprising:
- outputting, by the emission signal generation circuit, an emission signal having at least two Logic High sections to the display area of the display panel in response to an external clock signal;
- and
- receiving, by the emission signal generation circuit, the first scan signal that is output from the first shift register circuit of the scan signal generation circuit directly from the scan line travelling through the display area on the second side.
