Abstract

A display apparatus includes: a display panel configured to display an image; a window on the display panel having a transmissive area through which the image is transmitted and a non-transmissive area adjacent to the transmissive area, a case configured to accommodate the display panel and being coupled to the window; and a light sensor accommodated in the case at the non-transmissive area. The window includes a base member and a printed layer, and the base member has a first portion at the non-transmissive area and a second portion extending from the first portion at the transmissive area. The first portion has a curved upper surface and a recess. The printed layer is on a lower surface of the first portion and has an opening corresponding to the light sensor. The recess has a flat bottom surface overlapping the light sensor.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel configured to display an image;
a window on the display panel, the window having a transmissive area through which the image is transmitted and a non-transmissive area adjacent to the transmissive area, the window comprising a base member and a printed layer, the base member having a first portion at the non-transmissive area and a second portion at the transmissive area and extending from the first portion, the first portion having a curved upper surface and a recess;
a case configured to accommodate the display panel, the case being coupled to the window; and
a light sensor accommodated in the case overlapping the non-transmissive area,
wherein the printed layer is on a lower surface of the first portion and has an opening corresponding to the light sensor, and
wherein the recess has a flat bottom surface recessed from the upper surface of the first portion and overlapping the light sensor.

2. The display apparatus of claim 1 , wherein the recess has a side surface extending between the bottom surface and the upper surface of the first portion, and
wherein the side surface is inclined with respect to the bottom surface by an angle.

3. The display apparatus of claim 2 , wherein the angle is in a range of greater than about 0° to less than about 180°.

4. The display apparatus of claim 2 , wherein a length of a portion of the side surface nearer to the second portion from the bottom surface to the upper surface of the first portion is greater than a length of another portion of the side surface farther from the second portion from the bottom surface to the upper surface of the first portion.

5. The display apparatus of claim 2 , wherein the lower surface is flat.

6. The display apparatus of claim 5 , wherein a portion of the base member between the bottom surface of the recess and the lower surface of the first portion has a uniform thickness.

7. The display apparatus of claim 6 , wherein the bottom surface has an area that is greater than that of the opening.

8. The display apparatus of claim 2 , wherein the lower surface of the first portion has a flat surface portion overlapping the light sensor and a curved surface portion extending from the flat surface portion.

9. The display apparatus of claim 1 , wherein the base member comprises glass or plastic.

10. The display apparatus of claim 1 , wherein the light sensor comprises:
a light generator configured to generate light; and
a light receiver configured to receive the light generated by the light generator.

11. The display apparatus of claim 10 , wherein the light is infrared light.

12. The display apparatus of claim 1 , wherein the printed layer has a plurality of the openings, and
wherein adjacent ones of the openings are spaced from each other.

13. A window comprising:
a base member comprising:
a first portion configured to block light, the first portion having a curved upper surface and a recess, the recess having a flat bottom surface recessed from the upper surface of the first portion; and
a second portion configured to transmit light and extending from the first portion; and

a printed layer on a lower surface opposite the upper surface of the first portion, the printed layer having an opening,
wherein the recess overlaps the opening.

14. The window of claim 13 , wherein the recess has a side surface extending between the bottom surface and the upper surface of the first portion, and
wherein the side surface is inclined with respect to the bottom surface by an angle.

15. The window of claim 14 , wherein a portion of the base member between the bottom surface of the recess and the lower surface of the first portion has a uniform thickness.

16. The window of claim 14 , wherein the printed layer has a plurality of the openings, and
wherein the openings are spaced from each other.

17. The window of claim 16 , wherein the bottom surface of the recess has an area that is greater than a sum of areas of the openings.

18. The window of claim 16 , wherein the base member has a plurality of the recesses, and
wherein ones of the recesses respectively correspond to ones of the openings.

19. The window of claim 18 , wherein a bottom surface of each of the recesses has an area that is greater than that of each of the openings.

20. The window of claim 18 , wherein a bottom surface of each of the recesses has an area that is greater than that of corresponding ones of the openings.
