Abstract
A display device includes a display panel including a plurality of pixel rows, and a panel driver configured to drive the display panel. The panel driver includes a scan on time decider configured to receive line image data for each of the plurality of pixel rows, and to determine a scan on time change amount for each of the plurality of pixel rows based on the line image data, and a scan control block configured to adjust a scan pulse applied to each of the plurality of pixel rows according to the scan on time change amount.
Claims20
A display device comprising:
- a display panel comprising a plurality of pixel rows;
- and
- a panel driver configured to drive the display panel, the panel driver comprising:
- a scan on time decider configured to receive line image data for each of the plurality of pixel rows, and to determine a scan on time change amount for each of the plurality of pixel rows based on the line image data;
- and
- a scan control block configured to adjust a scan pulse applied to each of the plurality of pixel rows according to the scan on time change amount and to output a scan clock signal, a width of the scan clock signal being adjusted in response to the scan on time change amount,
- wherein the scan on time change amount is inversely related to a representative gray value of the line image data.
A display device comprising:
- a display panel comprising a plurality of pixel rows;
- and
- a panel driver configured to drive the display panel, the panel driver comprising:
- a data driver configured to provide data voltages to each of the plurality of pixel rows;
- a horizontal time decider configured to determine a horizontal time for each of the plurality of pixel rows according to a distance from the data driver to each of the plurality of pixel rows;
- and
- a scan control block configured to adjust a scan pulse applied to each of the plurality of pixel rows according to the determined horizontal time and to output a scan clock signal, a width of the scan clock signal being adjusted in response to a scan on time change amount for each of the plurality of pixel rows.
A display device comprising:
- a display panel comprising a plurality of pixel rows;
- and
- a panel driver configured to drive the display panel, the panel driver comprising:
- a timing decider configured to determine a scan on time for each of the plurality of pixel rows based on at least one of line image data for each of the plurality of pixel rows and a distance from a data driver to each of the plurality of pixel rows;
- and
- a scan control block configured to adjust a scan pulse applied to each of the plurality of pixel rows according to the determined scan on time and to output a scan clock signal, a width of the scan clock signal being adjusted in response to a scan on time change amount for each of the plurality of pixel rows.
