Abstract
A method of determining pixel luminance includes determining a smoothing reference line between a display region and a non-display region in a display panel, determining a boundary pixel, through which the smoothing reference line passes, among pixels included in the display region, dividing the boundary pixel into a first pixel region in the display region and a second pixel region in the non-display region based on the smoothing reference line, calculating a smoothing rate corresponding to a ratio of an area of the first pixel region to a total area of the boundary pixel, and determining dimming luminance of the boundary pixel based on the smoothing rate.
Claims21
A method of determining pixel luminance, the method comprising:
- determining a smoothing reference line between a display region and a non-display region in a display panel;
- determining a boundary pixel, through which the smoothing reference line passes, among pixels included in the display region;
- dividing the boundary pixel into a first pixel region in the display region and a second pixel region in the non-display region based on the smoothing reference line;
- calculating a smoothing rate corresponding to a ratio of an area of the first pixel region to a total area of the boundary pixel;
- and
- determining dimming luminance of the boundary pixel based on the smoothing rate.
A method of determining pixel luminance, the method comprising:
- determining a smoothing reference line between a display region and a non-display region in a display panel;
- determining a boundary sub-pixel, through which the smoothing reference line passes, among sub-pixels included in the display region;
- dividing the boundary sub-pixel into a first pixel region in the display region and a second pixel region in the non-display region based on the smoothing reference line;
- calculating a smoothing rate corresponding to a ratio of an area of the first pixel region to a total area of the boundary sub-pixel;
- and
- determining dimming luminance of the boundary sub-pixel based on the smoothing rate.
A display device comprising:
- a display panel including a display region and a non-display region;
- and
- a display panel driving circuit which drives the display panel,
- wherein the display panel driving circuit performs a luminance dimming on a boundary pixel, through which a smoothing reference line corresponding to a boundary between the display region and the non-display region passes, among pixels included in the display region, and
- wherein the display panel driving circuit does not perform the luminance dimming on a non-boundary pixel, through which the smoothing reference line does not pass, among the pixels.
