Abstract
A display device includes a display panel including a plurality of pixels, the display panel having an active region in which an image is displayed and an inactive region adjacent to the active region, an image processor setting image data of the inactive region to dummy data, and performing a rendering operation for a boundary pixel of the plurality of pixels based on the dummy data to generate output image data, the boundary pixel located in the active region and adjacent to the inactive region, and a panel driver providing a driving signal to the display panel to display the image corresponding to the output image data.
Claims20
A display device comprising:
- a display panel which includes a plurality of pixels, and has an active region in which an image is displayed and an inactive region adjacent to the active region;
- an image processor which sets image data of the inactive region to dummy data, and performs a rendering operation for a boundary pixel of the plurality of pixels based on the dummy data to generate output image data, the boundary pixel located in the active region and adjacent to the inactive region;
- and
- a panel driver which provides a driving signal to the display panel to display the image corresponding to the output image data.
A method of driving a display device which comprises a display panel including a plurality of pixels, and has an active region in which an image is displayed and an inactive region adjacent to the active region, the method comprising:
- receiving first input image data corresponding to the active region;
- setting second input image data corresponding to the inactive region to dummy data;
- converting the first input image data to first luminance data and converting the second input image data to second luminance data;
- performing a rendering operation for a boundary pixel of the plurality of pixels based on the first luminance data and the second luminance data to generate output image data, the boundary pixel located in the active region and adjacent to the inactive region;
- and
- displaying the image corresponding to the output image data.
