Abstract

A display apparatus includes a substrate including a display area and a sensor area, the sensor area including an auxiliary display area and a transmitting area, first display elements arranged over the display area, second display elements arranged over the auxiliary display area, transmitting units arranged in the transmitting area and configured to transmit at least a portion of light incident on the transmitting units, and an optical layer including a mesh pattern covering at least the second display elements.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate including a display area and a sensor area, the sensor area including an auxiliary display area and a transmitting area;
a plurality of first display elements arranged over the display area;
a plurality of second display elements arranged over the auxiliary display area;
a plurality of transmitting units arranged in the transmitting area and configured to transmit at least a portion of light incident on the transmitting area; and
an encapsulation substrate covering the plurality of first display elements and the plurality of second display elements and the encapsulation substrate includes a plurality of grooves overlapping the plurality of second display elements,
wherein a number of the plurality of grooves overlapping a light emitting region of one of the plurality of second display elements is at least two.

2. The display apparatus of claim 1 , wherein the encapsulation substrate comprises a first surface facing the substrate and a second surface opposite the first surface, and the plurality of grooves is disposed on the second surface.

3. The display apparatus of claim 1 , wherein the plurality of grooves do not overlap the plurality of first display elements.

4. The display apparatus of claim 1 , wherein the plurality of grooves include a first group of grooves extending in a first direction and a second group of grooves extending in a second direction different from the first direction.

5. The display apparatus of claim 1 , wherein the plurality of grooves are arranged in a mesh pattern.

6. The display apparatus of claim 1 ,
wherein the plurality of second display elements are grouped into a plurality of pixel units, and
wherein each of the plurality of pixel units and each of the plurality of transmitting units are alternately arranged.

7. The display apparatus of claim 1 ,
wherein each of the plurality of first display elements and the plurality of second display elements comprises:
a pixel electrode electrically connected to a thin film transistor;
an emission layer on the pixel electrode; and
an opposite electrode on the emission layer.

8. A display apparatus comprising:
a substrate including a display area and a sensor area, the sensor area including an auxiliary display area and a transmitting area;
a plurality of first display elements arranged over the display area;
a plurality of second display elements arranged over the auxiliary display area;
a plurality of transmitting units arranged in the transmitting area and configured to transmit at least a portion of light incident on the transmitting area; and
a thin film encapsulation layer covering the plurality of first display elements and the plurality of second display elements,
wherein the thin film encapsulation layer includes a first inorganic layer, an organic layer, and a second inorganic layer, which are sequentially stacked, and
wherein the second inorganic layer includes a plurality of grooves overlapping the plurality of second display elements,
wherein a number of the plurality of grooves overlapping a light emitting region of one of the plurality of second display elements is at least two.

9. The display apparatus of claim 8 , wherein the plurality of grooves is disposed on an upper surface of the second inorganic layer.

10. The display apparatus of claim 8 , wherein the plurality of grooves do not overlap the plurality of first display elements.

11. The display apparatus of claim 8 , wherein the plurality of grooves include a first group of grooves extending in a first direction and a second group of grooves extending in a second direction different from the first direction.

12. The display apparatus of claim 8 , wherein the plurality of grooves are arranged in a mesh pattern.

13. The display apparatus of claim 8 ,
wherein the plurality of second display elements are grouped into a plurality of pixel units, and
wherein each of the plurality of pixel units and each of the plurality of transmitting units are alternately arranged.

14. The display apparatus of claim 8 ,
wherein each of the plurality of first display elements and the plurality of second display elements comprises:
a pixel electrode electrically connected to a thin film transistor;
an emission layer on the pixel electrode; and
an opposite electrode on the emission layer.

15. The display apparatus of claim 8 , further comprising:
a thin film transistor disposed between the substrate and the plurality of second display elements; and
a planarization layer covering the thin film transistor,

wherein the planarization layer include a transmitting opening corresponding to the transmitting area.
