Abstract

A display device includes a backlight module and a display panel. The display panel is disposed on the backlight module and includes two substrates, a sensor, and a light-shielding element. The sensor is disposed between the two substrates. The light-shielding element at least partially surrounds the sensor. A height of the light-shielding element is greater than a height of the sensor.

First claim

What is claimed is:

1 . An electronic device, comprising:
a substrate; a sensor disposed on the substrate; and a light-shielding element at least partially surrounding the sensor; wherein a height of the light-shielding element is greater than a height of the sensor, and wherein a portion of the light-shielding element is between the sensor and the substrate.

2 . The electronic device of claim 1 , wherein a length of the portion of the light-shielding element is greater than or equal to a thickness of the sensor.

3 . The electronic device of claim 1 , wherein the portion of the light-shielding element is a conductor.

4 . An electronic device, comprising:
a substrate; a sensor disposed on the substrate; a light-shielding element at least partially surrounding the sensor; and an insulating layer having a recess, wherein at least a portion of the light-shielding element is disposed in the recess.

5 . The electronic device of claim 4 , wherein the sensor is disposed in the recess and on the light-shielding element.

6 . The electronic device of claim 4 , wherein the light-shielding element comprises a light-absorbing element, a light-reflecting element, or a combination of the above.

7 . An electronic device, comprising:
a substrate; a sensor disposed on the substrate; and a light-shielding element, wherein a portion of the light-shielding element is between the sensor and the substrate; wherein a length of the portion of the light-shielding element is greater than or equal to a thickness of the sensor.

8 . The electronic device of claim 7 , wherein a height of the portion of the light-shielding element is smaller than a height of the sensor.

9 . The electronic device of claim 7 , wherein the light-shielding element comprises a light-absorbing element, a light-reflecting element, or a combination of the above two.

10 . The electronic device of claim 7 , further comprising:
an electrode disposed between the sensor and the substrate, wherein the electrode is used as the portion of the light-shielding element between the sensor and the substrate.

11 . The electronic device of claim 10 , further comprising:
a plurality of signal wires used as another portion of the light-shielding element, wherein the sensor is disposed between the plurality of signal wires, and the electrode is disposed between the plurality of signal wires and the substrate.

12 . The electronic device of claim 11 , wherein the signal wires are separated from the electrode via an insulating layer, and the signal wires, the insulating layer, and the electrode form a capacitor.

13 . The electronic device of claim 11 , wherein the signal wires are in contact with the electrode.

14 . The electronic device of claim 11 , further comprising:
an insulating layer disposed on the sensor, and a surface of the insulating layer presents an arc shape.

15 . The electronic device of claim 14 , wherein the signal wires are overlapped with the insulating layer and have an opening exposing the sensor, and a maximum width of the opening is between 0.6 and 1.5 times a maximum width of the sensor.
