Abstract

A panel assembly includes a transparent cover, a display module, a decorative layer, and a Fresnel lens structure. The transparent cover has a lower surface. The display module is disposed under the lower surface. The decorative layer is disposed on the lower surface. The Fresnel lens structure is located above the display module. Besides, an electronic device includes a frame, a housing, and the above panel assembly, and the housing and the panel assembly are installed in the frame.

First claim

What is claimed is:

1 . A panel assembly, comprising:
a transparent cover comprising a lower surface; a display module disposed under the lower surface; a decorative layer disposed on the lower surface; and a Fresnel lens structure located above the display module.

2 . The panel assembly according to claim 1 , wherein the lower surface comprises a central region and a peripheral region outside the central region, and the decorative layer is disposed on the peripheral region of the lower surface.

3 . The panel assembly according to claim 2 , wherein the Fresnel lens structure is disposed at least corresponding to a junction of the central region and the peripheral region.

4 . The panel assembly according to claim 3 , wherein the central region is rectangular and comprises a pair of long sides and a pair of short sides, and the Fresnel lens structure is disposed along the pair of long sides.

5 . The panel assembly according to claim 3 , wherein the central region is rectangular and comprises a pair of long sides and a pair of short sides, the Fresnel lens structure is disposed along the pair of long sides and the pair of short sides, and a curvature of a portion of the Fresnel lens structure disposed on the pair of long sides is larger than a curvature of a portion of the Fresnel lens structure disposed on the pair of short sides.

6 . The panel assembly according to claim 1 , further comprising:
a touch module disposed between the transparent cover and the display module, wherein the touch module comprises a transparent circuit region and a non-transparent circuit region.

7 . The panel assembly according to claim 3 , wherein the Fresnel lens structure is disposed corresponding to the whole central region.

8 . The panel assembly according to claim 1 , wherein the Fresnel lens structure is formed on the lower surface of the transparent cover.

9 . The panel assembly according to claim 1 , further comprising:
a thin film, wherein the Fresnel lens structure is formed on the thin film, and the thin film is disposed between the transparent cover and the display module.

10 . The panel assembly according to claim 1 , further comprising:
a transparent adhesive layer covering the Fresnel lens structure, wherein the decorative layer is disposed on the lower surface.

11 . The panel assembly according to claim 1 , wherein the Fresnel lens structure is a diverging lens or a converging lens.

12 . An electronic device, comprising:
a frame; a housing installed in the frame; and a panel assembly installed in the frame and comprising:
a transparent cover comprising a lower surface;
a display module disposed under the lower surface;
a decorative layer disposed on the lower surface; and
a Fresnel lens structure located above the display module.

13 . The electronic device according to claim 12 , wherein the lower surface comprises a central region and a peripheral region outside the central region, and the decorative layer is disposed on the peripheral region of the lower surface.

14 . The electronic device according to claim 13 , wherein the Fresnel lens structure is disposed at least corresponding to a junction of the central region and the peripheral region.

15 . The electronic device according to claim 14 , wherein the central region is rectangular and comprises a pair of long sides and a pair of short sides, and the Fresnel lens structure is disposed along the pair of long sides.

16 . The electronic device according to claim 14 , wherein the central region is rectangular and comprises a pair of long sides and a pair of short sides, the Fresnel lens structure is disposed along the pair of long sides and the pair of short sides, and a curvature of a portion of the Fresnel lens structure disposed on the pair of long sides is larger than a curvature of a portion of the Fresnel lens structure disposed on the pair of short sides.

17 . The electronic device according to claim 13 , wherein the Fresnel lens structure is disposed corresponding to the whole central region.

18 . The electronic device according to claim 12 , wherein the panel assembly further comprises:
a touch module disposed between the transparent cover and the display module, wherein the touch module comprises a transparent circuit region and a non-transparent circuit region.

19 . The electronic device according to claim 12 , wherein the Fresnel lens structure is formed on the lower surface of the transparent cover.

20 . The electronic device according to claim 12 , wherein the panel assembly further comprises:
a thin film, wherein the Fresnel lens structure is formed on the thin film, and the thin film is disposed between the transparent cover and the display module.

21 . The electronic device according to claim 12 , wherein the panel assembly further comprises:
a transparent adhesive layer covering the Fresnel lens structure, wherein the decorative layer is disposed on the lower surface.

22 . The electronic device according to claim 12 , wherein the Fresnel lens structure is a diverging lens or a converging lens.
