Abstract

An electronic device is provided. The electronic device includes a light-emitting element, a cover plate and a light-shielding layer. The cover plate is disposed on the light-emitting element. The light-shielding layer is disposed on a side of the cover plate adjacent to the light-emitting element. The light-shielding layer has an icon area, and the light-shielding layer has a plurality of openings in the icon area. In addition, the plurality of openings have an aperture ratio in the icon area, and the aperture ratio is greater than 0% and less than or equal to 20%.

First claim

What is claimed is:

1 . An electronic device, comprising:
a light-emitting element; a cover plate disposed on the light-emitting element; and a light-shielding layer disposed on a side of the cover plate adjacent to the light-emitting element, wherein the light-shielding layer has an icon area, and the light-shielding layer has a plurality of openings in the icon area; wherein the plurality of openings have an aperture ratio in the icon area, and the aperture ratio is greater than 0% and less than or equal to 20%, wherein the aperture ratio is as shown in the following formula: the aperture ratio (%)=a total area of the plurality of openings/(the total area of the plurality of openings+a total area of the light-shielding layer)×100%.

2 . The electronic device as claimed in claim 1 , wherein at least one of the plurality of openings has a pore diameter, and the pore diameter is between 20 micrometers and 40 micrometers.

3 . The electronic device as claimed in claim 1 , wherein there is a pitch between two adjacent openings among the plurality of openings, and the pitch is between 85 micrometers and 140 micrometers.

4 . The electronic device as claimed in claim 1 , wherein the aperture ratio is greater than 0% and less than or equal to 10%.

5 . The electronic device as claimed in claim 1 , wherein the plurality of openings comprise a plurality of first openings arranged equidistantly along a periphery of the icon area.

6 . The electronic device as claimed in claim 1 , further comprising:
a glue layer disposed on a side of the light-shielding layer adjacent to the light-emitting element.

7 . The electronic device as claimed in claim 6 , wherein the glue layer is a transparent glue layer.

8 . The electronic device as claimed in claim 6 , wherein the glue layer has a thickness, and the thickness is between 200 micrometers and 1000 micrometers.

9 . The electronic device as claimed in claim 1 , wherein at least one of the plurality of openings has a top width and a bottom width, and the top width is different from the bottom width.

10 . The electronic device as claimed in claim 9 , wherein the top width is less than the bottom width.

11 . The electronic device as claimed in claim 9 , wherein the top width is greater than the width of the bottom width.

12 . The electronic device as claimed in claim 1 , wherein the light-shielding layer has a thickness, and the thickness is between 1 micrometers and 20 micrometers.

13 . The electronic device as claimed in claim 1 , wherein the plurality of openings are arranged in a matrix or concentric circles.

14 . The electronic device as claimed in claim 1 , wherein there is a gap between the light-emitting element and the light-shielding layer.

15 . The electronic device as claimed in claim 1 , wherein the light-shielding layer is adhered on the light-emitting element.

16 . The electronic device as claimed in claim 1 , wherein a material of the light-shielding layer comprises black photoresist, black printing ink, black resin, metal, carbon black material, resin material, photosensitive material, or a combination thereof.

17 . The electronic device as claimed in claim 1 , wherein the light-emitting element comprises a light-emitting diode, an organic light-emitting diode, electroluminescence, or a combination thereof.

18 . The electronic device as claimed in claim 1 , wherein the light-emitting element is independent of a panel or a backlight source of a panel.

19 . The electronic device as claimed in claim 1 , wherein an expected transmittance of the cover plate is greater than 0% and less than or equal to 20%, and the expected transmittance is as shown in the following formula:
the expected transmittance of the cover plate (%)=the aperture ratio×a transmittance of the cover plate.
