Abstract
A display device includes: a display panel including a plurality of pixels each coupled to a scan line and a data line; a scan driver for supplying a scan signal having at least one scan pulse to the scan line; and a pulse controller for adjusting a number of the scan pulses supplied during one frame, based on an image variation between a previous frame and a current frame.
Claims18
A display device comprising:
- a display panel comprising a plurality of pixels each coupled to a scan line and a data line;
- a scan driver configured to supply a scan signal having at least one scan pulse to the scan line;
- and
- a pulse controller configured to adjust a number of the scan pulses supplied during one frame, based on an image variation between a previous frame and a current frame,
- wherein the pulse controller is configured to increase the number of scan pulses supplied in the one frame in response to the image variation being increased.

A display device comprising:
- a display panel comprising a plurality of pixels each coupled to a scan line and a data line;
- a scan driver configured to supply a scan signal having at least one scan pulse to the scan line;
- and
- a pulse controller configured to adjust a number of the scan pulses supplied during one frame, based on an image variation between a previous frame and a current frame,
- wherein the pulse controller comprises:
- a frame memory configured to store image data in a frame unit;
- an image variation calculator configured to calculate a grayscale value variation between the image data of the previous frame and the image data of the current frame;
- and
- a pulse determiner configured to determine the number of scan pulses supplied in the current frame by comparing the grayscale value variation with preset threshold values, and
- wherein the pulse determiner is configured to:
- in response to the grayscale value variation being 0, determine the number of scan pulses as 1;
- and
- in response to the grayscale value variation being larger than 0, adjust the number of scan pulses according to variation ranges divided by the threshold values.
