Abstract
A display device includes a display panel including a plurality of pixels, an image data corrector configured to generate a corrected image data by adjusting an image data and a data driver providing data signals to the plurality of pixels based on the corrected image data. The image data corrector divides the display panel into a plurality of unit areas, and adjust the image data for a unit area among the plurality of unit areas by using a full image load for the entire display panel, a first image load for the unit area, and a second image load for peripheral unit areas surrounding the unit area among the plurality of unit areas.
Claims17
A display device comprising:
- a display panel including a plurality of pixels;
- an image data corrector receiving image data from an external device and generating corrected image data by adjusting the image data;
- and
- a data driver providing data signals to the plurality of pixels based on the corrected image data,
- wherein the image data corrector divides the display panel into a plurality of unit areas, and adjust the image data for a unit area among the plurality of unit areas by using a full image load for the entire display panel, a first image load for the unit area, and a second image load for peripheral unit areas surrounding the unit area among the plurality of unit areas, and
- wherein the full image load is a current luminance corresponding to the image data for the entire display panel divided by a maximum luminance corresponding to the image data for the entire display panel, the first image load is a current unit area luminance corresponding to an image data for the unit area divided by a maximum luminance corresponding to the image data for the unit area, and the second image load is a current peripheral unit area luminance corresponding to an image data for the peripheral unit areas divided by a maximum luminance corresponding to the image data for the peripheral unit.
A method of operating a display device which displays an image on a display panel including a plurality of unit areas by adjusting a luminance of an image data received from an external device, the method comprising:
- calculating a full image load for the entire display panel, a first image load for a unit area among the plurality of unit areas, and a second image load for peripheral unit areas surrounding the unit area;
- and
- adjusting the luminance of the image data received from the external device for the unit area using the full image load, the first image load, and the second image load,
- wherein the full image load is a current luminance corresponding to the image data for the entire display panel divided by a maximum luminance corresponding to the image data for the entire display panel, the first image load is a current unit area luminance corresponding to the image data for the unit area divided by a maximum luminance corresponding to the image data for the unit area, and the second image load is a current peripheral unit area luminance corresponding to the image data for the peripheral unit areas divided by a maximum luminance corresponding to the image data for the peripheral unit areas.
