Abstract

Provided is a display apparatus including a substrate having a display area including a main pixel, and a sensor area including a sub-pixel and a transmission portion, a plurality of first lines arranged in the sensor area, extending in a first direction, and bypassing the transmission portion, and a first electrode layer under the plurality of first lines, between the sub-pixel and the transmission portion, and at least partially overlapping a spacing region between the plurality of first lines.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate having a display area, and a sensor area comprising a transmission portion;
a bottom metal layer on the sensor area, and defining an opening corresponding to the transmission portion;
a thin film transistor on the bottom metal layer, and comprising a semiconductor layer and a gate electrode on the semiconductor layer; and
an organic light-emitting diode electrically connected to the thin film transistor, and comprising a pixel electrode, an organic emission layer, and an opposite electrode,
wherein the bottom metal layer fully overlaps an emission area of the organic light-emitting diode, and
wherein a resolution of an image provided by the sensor area is less than a resolution of an image provided by the display area.

2. The display apparatus of claim 1 , further comprising a pixel group comprising a plurality of sub-pixels at the sensor area, wherein the bottom metal layer overlaps an entirety of the pixel group.

3. The display apparatus of claim 2 , wherein the transmission portion and the pixel group are provided in plurality, and
wherein the transmission portion and the pixel group are alternately arranged.

4. The display apparatus of claim 1 , further comprising a plurality of first lines arranged at the sensor area and extending in a first direction,
wherein the plurality of first lines are arranged to bypass along an edge of the transmission portion.

5. The display apparatus of claim 4 , wherein at least some of the plurality of first lines overlap the bottom metal layer.

6. A display apparatus comprising:
a substrate having a display area, and a sensor area comprising a transmission portion;
a bottom layer on the sensor area;
a thin film transistor on the bottom layer, and comprising a semiconductor layer and a gate electrode on the semiconductor layer;
an organic light-emitting diode electrically connected to the thin film transistor, and comprising a pixel electrode, an organic emission layer, and an opposite electrode; and
first lines arranged at the sensor area to bypass along an edge of the transmission portion, extending in a first direction, and comprising at least one of a scan line, an emission control line, or an initialization voltage line,
wherein the bottom layer fully overlaps an emission area of the organic light-emitting diode, and
wherein a resolution of an image provided by the sensor area is less than a resolution of an image provided by the display area.

7. A display apparatus comprising:
a substrate having a display area, and a sensor area comprising a transmission portion;
a bottom layer on the sensor area;
a thin film transistor on the bottom layer, and comprising a semiconductor layer and a gate electrode on the semiconductor layer;
an organic light-emitting diode electrically connected to the thin film transistor, and comprising a pixel electrode, an organic emission layer, and an opposite electrode;
first lines arranged at the sensor area to bypass along an edge of the transmission portion, and extending in a first direction; and
a driving voltage line extending in a second direction crossing the first direction, and connected to the bottom layer through a contact hole,
wherein the bottom layer fully overlaps an emission area of the organic light-emitting diode, and
wherein a resolution of an image provided by the sensor area is less than a resolution of an image by the display area.

8. The display apparatus of claim 4 , further comprising a plurality of second lines extending in a second direction crossing the first direction,
wherein the plurality of second lines are arranged to bypass along an edge of the transmission portion.

9. The display apparatus of claim 8 , wherein at least some of the plurality of second lines overlap the bottom metal layer.

10. The display apparatus of claim 8 , wherein the plurality of second lines comprises at least one of a data line or a driving voltage line.

11. The display apparatus of claim 8 , wherein the transmission portion is surrounded by at least a portion of the plurality of first lines, the plurality of second lines, and the bottom metal layer.

12. The display apparatus of claim 1 , further comprising a component corresponding to the sensor area on a lower surface of the substrate, and configured to detect light or sound.

13. The display apparatus of claim 1 , further comprising an electrode layer on the display area, wherein the electrode layer overlaps a main thin-film transistor on the display area, and the electrode layer is between the substrate and the main thin-film transistor.
