Abstract
A foldable display apparatus includes: a non-folding area, and a folding area, in which an aperture ratio of a plurality of red sub pixels in the folding area is lower than an aperture ratio of a plurality in red sub pixels of the non-folding area, an aperture ratio of the plurality of green sub pixels in the folding area is lower than an aperture ratio of the plurality of green sub pixels of the non-folding area, and an aperture ratio of the plurality in blue sub pixels of the folding area is lower than an aperture ratio of the plurality of blue sub pixels of the non-folding area.
Claims19
A foldable display apparatus, comprising:
- a substrate including a folding area;
- a plurality of sub pixels on the substrate, the plurality of sub pixels including a plurality of red sub pixels, a plurality of green sub pixels, and a plurality of blue sub pixels,
- wherein at least one of the plurality of red sub pixels, the plurality of green sub pixels, or the plurality of blue sub pixels includes a first subset of sub pixels disposed in an area outside the folding area with a first aperture ratio, and a second subset of sub pixels disposed in the folding area with a second aperture ratio lower than the first aperture ratio,
- wherein each of the plurality of sub pixels includes:
- an anode;
- a cathode;
- and
- a light emitting layer between the anode and the cathode, and
- wherein an aperture ratio of a sub pixel in the plurality of sub pixels indicates a ratio between a light emitting area where the anode and the cathode of the sub pixel overlap and an area of the sub pixel.
A foldable display apparatus, comprising:
- a substrate including a folding area;
- and
- a plurality of sub pixels on the substrate, the plurality of sub pixels including:
- a first subset of sub pixels in an area outside the folding area, the first subset of sub pixels configured to emit a color of light, and
- a second subset of sub pixels in the folding area on the substrate, the second subset of sub pixels configured to emit the color of light, each of the plurality of sub pixels including a light emitting diode,
- wherein the light emitting diode of each of the plurality of sub pixels includes a light emitting layer, and
- a second thickness of the light emitting layers of the second subset of sub pixels in the folding area is larger than a first thickness of the light emitting layers of the first subset of sub pixels in the area outside the folding area.
