Abstract
An organic light emitting display apparatus includes a plurality of subpixels in an emission region; and a planarization layer in the plurality of subpixels, the planarization layer including a plurality of light extraction patterns including a convex portion and a plurality of concave portions. At least a first light extraction pattern of the plurality of light extraction patterns is rotated with respect to a center portion of each of the plurality of concave portions.
Claims20
An organic light emitting display apparatus, comprising:
- a plurality of subpixels in an emission region;
- and
- a planarization layer in the plurality of subpixels, the planarization layer including a plurality of light extraction patterns including a convex portion and a plurality of concave portions,
- wherein at least a first light extraction pattern of the plurality of light extraction patterns is rotated with respect to a center portion of each of the plurality of concave portions.
An organic light emitting display apparatus, comprising:
- a substrate having edges defined parallel to a first direction and a second direction;
- a plurality of subpixels in an emission region defined on the substrate;
- and
- a planarization layer in the plurality of subpixels, the planarization layer including a plurality of light extraction patterns including a plurality of concave portions in each subpixel,
- wherein a direction between centers of any adjacent ones of the light extraction patterns is not parallel to the first direction or the second direction.
An organic light emitting display apparatus, comprising:
- a substrate having edges defined parallel to a first direction and a second direction;
- a plurality of subpixels in an emission region defined on the substrate;
- and
- a planarization layer in the plurality of subpixels, the planarization layer including a plurality of light extraction patterns including a plurality of concave portions in each subpixel,
- wherein each one of the light extraction patterns has a shape defining one or more symmetry axis, the one or more symmetry axis being rotated with respect to the first and second directions to define an angle with respect to the first and second directions.
An organic light emitting display apparatus, comprising:
- a substrate having a plurality of subpixels defined in an emission region of the substrate;
- a planarization layer on the substrate in the plurality of subpixels, the planarization layer having an upper surface including a plurality of concave portions in each subpixel, and
- a light emitting device in each of the plurality of plurality of subpixels, each light emitting device being on the concave portions of the respective subpixel and having a shape conforming to the respective concave portions.
