Abstract

A display device including a substrate including a display region, an ambient light sensing element, and an ambient light sensing signal line is provided by the present disclosure. The substrate includes a metal line, wherein at least a portion of the metal line is disposed in the display region. The ambient light sensing signal line is electrically connected to the ambient light sensing element and partially overlapped with the at least a portion of the metal line in a top view direction.

First claim

What is claimed is:

1. A display device, comprising:
a substrate having a display region, comprising:
at least one data line and at least one scan line disposed in the display region;

an ambient light sensing element; and
an ambient light sensing signal line electrically connected to the ambient light sensing element, wherein the ambient light sensing signal line overlaps the at least one data line and overlaps the at least one scan line in the display region in a top view direction of the display device.

2. The display device according to claim 1 , wherein the at least one data line crosses the at least one scan line.

3. The display device according to claim 1 , wherein the at least one data line and the at least one scan line are disposed in different layers.

4. The display device according to claim 3 , wherein the substrate comprises a first metal layer and a second metal layer disposed on the substrate in sequence from bottom to top, the at least one scan line is formed of the first metal layer, and the at least one data line is formed of the second metal layer.

5. The display device according to claim 1 , wherein the ambient light sensing element is disposed outside the display region.

6. The display device according to claim 1 , wherein the ambient light sensing signal line comprises copper, silver, gold or aluminum.

7. The display device according to claim 1 , further comprising a multiplexer disposed outside the display region.

8. The display device according to claim 1 , further comprising a gate driving circuit disposed outside the display region.

9. The display device according to claim 8 , wherein the gate driving circuit comprises an amplifier, a signal line or a shift register.
