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.
Claims15
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,
- wherein each of the pixels includes sub-pixels, and a luminance dimming is performed on all of the sub-pixels of the boundary pixel based on the dimming luminance determined based on the smoothing rate corresponding to the ratio of the area of the first pixel region to the total area of the boundary pixel including the sub-pixels.
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 divides 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 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, and performs a luminance dimming on the boundary pixel, wherein each of the pixels includes sub-pixels, and the luminance dimming is performed on all of the sub-pixels of the boundary pixel based on a dimming luminance determined based on a smoothing rate corresponding to a ratio of an area of a first pixel region to a total area of the boundary pixel including the sub-pixels, 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.
