Abstract
An optical filter which minimizes color shift, increases brightness and improves visibility and an organic light-emitting display having the same. The optical filter includes a micro pattern film disposed on an organic light-emitting panel. The micro pattern film includes a base material and a micro pattern engraved from the surface of the base material that adjoins the organic light-emitting panel. The micro pattern has a plurality of engraved shapes with a non-circular cross-section which has a depth greater than a width.
Claims19
An optical filter for an organic light-emitting display, comprising a micro pattern film disposed on an organic light-emitting panel, wherein the micro pattern film comprises:
- a base material;
- and
- a micro pattern engraved from a surface of the base material that adjoins the organic light-emitting panel, the micro pattern having a plurality of engraved shapes with a non-circular cross-section which has a depth greater than a width.
An organic light-emitting display comprising:
- an organic light-emitting panel comprising organic light-emitting devices which emit red, green, blue or white light, the organic light-emitting devices having different heights from each other depending on wavelengths of emitted light;
- and
- an optical filter comprising a micro pattern film disposed on the organic light-emitting panel, the micro pattern film comprising a micro pattern engraved from a surface of a base material that adjoins the organic light-emitting panel, the micro pattern having a plurality of engraved shapes which have a depth greater than a width.
