Abstract
A display device according to an embodiment of the present disclosure may include a first memory configured to store degradation information; a second memory configured to store degradation compensation data; a timing controller configured to, when receiving image data from a host system, compensate the image data using the degradation compensation data; and a display panel including a plurality of light emitting elements, and configured to display an image according to compensated image data using at least some of the plurality of light emitting elements, wherein the degradation compensation data is classified on the basis of light emitting colors of the plurality of light emitting elements.
Claims17
A display device comprising:
- a first memory configured to store degradation information;
- a second memory configured to store degradation compensation data;
- a timing controller configured to compensate the image data using the degradation compensation data when receiving image data from a host system;
- and
- a display panel including a plurality of light emitting elements, and configured to display an image according to the compensated image data using at least some of the plurality of light emitting elements,
- wherein the degradation compensation data is classified on the basis of light emitting colors of the plurality of light emitting elements, and
- wherein a size of the degradation compensation data for one of the plurality of light emitting elements emitting a first color is smaller than the size of the degradation compensation data for another one of the plurality of light emitting elements emitting a second color different from the first color having lower resistance to degradation than the first color.
A method for operating a display device, comprising:
- generating degradation compensation data on the basis of degradation information stored in a first memory, and storing the generated degradation compensation data in a second memory;
- compensating the image data using the degradation compensation data stored in the second memory when receiving image data from a host system;
- and
- displaying an image according to the compensated image data using at least some of a plurality of light emitting elements,
- wherein the degradation compensation data is classified on the basis of light emitting colors of the plurality of light emitting elements, and
- wherein a size of the degradation compensation data for one of the plurality of light emitting elements emitting a first color is smaller than the size of the degradation compensation data for another one of the plurality of light emitting elements emitting a second color different from the first color having lower resistance to degradation than the first color.
A display device comprising:
- a first memory configured to store degradation information;
- a second memory configured to store degradation compensation data;
- a timing controller configured to compensate the image data using the degradation compensation data when receiving image data from a host system;
- and
- a display panel including a plurality of light emitting elements, and configured to display an image according to the compensated image data using at least some of the plurality of light emitting elements,
- wherein the degradation compensation data is prepared by reflecting degradation characteristics on the basis of light emitting colors of the plurality of light emitting elements, and
- wherein a size of the degradation compensation data for one of the plurality of light emitting elements emitting a first color is smaller than the size of the degradation compensation data for another one of the plurality of light emitting elements emitting a second color different from the first color having lower resistance to degradation than the first color.
