Abstract
A display apparatus includes a substrate including a display area and a sensor area, the display area including main pixels and the sensor area including auxiliary pixels and a transmission area, a plurality of display elements included in each of the main pixels and each of the auxiliary pixels, a first stack structure overlapping the plurality of display elements, a second stack structure overlapping the transmission area, and a thin film encapsulation layer covering the first stack structure and the second stack structure, wherein the first stack structure has a thickness that is different from a thickness of the second stack structure.
Claims19
A display apparatus comprising:
- a substrate comprising a display area and a sensor area, the display area comprising main pixels and the sensor area comprising auxiliary pixels and a transmission area;
- a plurality of display elements included in each of the main pixels and each of the auxiliary pixels;
- a first stack structure overlapping the plurality of display elements;
- a second stack structure overlapping the transmission area;
- and
- a thin film encapsulation layer covering the first stack structure and the second stack structure,
- wherein the first stack structure has a thickness that is different from a thickness of the second stack structure,
- each of the first stack structure and the second stack structure comprises a capping layer and a light extraction layer disposed on the capping layer,
- the thin film encapsulation layer is disposed on the light extraction layer and comprises a first inorganic encapsulation layer, and
- a refractive index of the light extraction layer is less than a refractive index of the capping layer and a refractive index of the first inorganic encapsulation layer.
A display apparatus comprising:
- a substrate comprising a transmission area and a display area surrounding the transmission area;
- a plurality of display elements in the display area;
- a thin film encapsulation layer covering the transmission area and the plurality of display elements;
- a capping layer disposed between the plurality of display elements and the thin film encapsulation layer to cover the transmission area;
- and
- a light extraction layer disposed between the capping layer and the thin film encapsulation layer,
- wherein at least one of the capping layer and the light extraction layer disposed in a region corresponding to the transmission area has a greater thickness than a region disposed corresponding to the plurality of display elements, and
- a refractive index of the light extraction layer is less than a refractive index of the capping layer and a refractive index of the thin film encapsulation layer.
