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; a thin film transistor on the bottom metal layer, and comprising a semiconductor layer, and a gate electrode on the semiconductor layer; and a light-emitting diode electrically connected to the thin film transistor, wherein an edge of the bottom metal layer is at least partially curved in a plan view, and wherein the edge of the bottom metal layer surrounds at least two light-emitting diodes in the plan view.

2 . The display apparatus of claim 1 , wherein an edge of the transmission portion is at least partially curved in a plan view.

3 . The display apparatus of claim 1 , wherein the bottom metal layer includes an opening corresponding to the transmission portion, and an edge of the opening is at least partially curved in a plan view.

4 . The display apparatus of claim 1 , wherein the bottom metal layer fully overlaps an emission area of the light-emitting diode.

5 . The display apparatus of claim 1 , wherein a pixel group comprising a plurality of sub-pixels is in the sensor area, the bottom metal layer overlapping an entirety of the pixel group.

6 . The display apparatus of claim 5 , wherein the transmission portion and the pixel group are provided in plurality, and
wherein the transmission portion and the pixel group are alternately arranged.

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

8 . The display apparatus of claim 7 , wherein at least some of the plurality of first lines overlap the bottom metal layer.

9 . The display apparatus of claim 7 , wherein the plurality of first lines comprises a scan line, an emission control line, and an initialization voltage line.

10 . The display apparatus of claim 7 , further comprising a driving voltage line extending in a second direction crossing the first direction,
wherein the bottom metal layer is connected to the driving voltage line through a contact hole.

11 . The display apparatus of claim 7 , further comprising a plurality of second lines extending in a second direction crossing the first direction,
wherein the plurality of second lines is arranged to bypass along the edge of the transmission portion.

12 . The display apparatus of claim 11 , wherein at least some of the plurality of second lines overlap the bottom metal layer.

13 . The display apparatus of claim 11 , wherein the plurality of second lines comprises a data line and a driving voltage line.

14 . The display apparatus of claim 11 , 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.

15 . The display apparatus of claim 1 , wherein a resolution of an image provided by the sensor area is less than a resolution of an image provided by the display area.

16 . The display apparatus of claim 1 , further comprising a component corresponding to the sensor area on a lower surface of the substrate.

17 . The display apparatus of claim 1 , further comprising an electrode layer on the display area, and at a same layer as the bottom metal layer, 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.

18 . The display apparatus of claim 1 , wherein the light-emitting diode is an organic light-emitting diode comprising a pixel electrode, an organic emission layer, and an opposite electrode.

19 . The display apparatus of claim 1 , wherein the substrate further comprises an opening area, and wherein light transmittance of the opening area is greater than light transmittance of the sensor area.

20 . A display apparatus comprising:
a substrate having a display area, a sensor area comprising a transmission portion, and an opening area having light transmittance that is greater than light transmittance of the sensor area; a bottom metal layer on the sensor area, and having an edge that is at least partially curved in a plan view; a thin film transistor on the bottom metal layer, and comprising a semiconductor layer, and a gate electrode on the semiconductor layer; a light-emitting diode electrically connected to the thin film transistor; a first component corresponding to the sensor area on a lower surface of the substrate; and a second component corresponding to the opening area on the lower surface of the substrate.
