## Abstract

An electronic device includes: a back plate; an optical film disposed on the back plate; and a support module disposed between the back plate and the optical film, wherein the support module includes a base, and the base includes a hollow space and a curved surface away from the back plate.

## Claims

### Claim 1

An electronic device, comprising:
a back plate;
an optical film disposed on the back plate; and
a support module disposed between the back plate and the optical film,
wherein the support module comprises a base, and the base comprises a hollow space and a curved surface away from the back plate.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the curved surface comprises a first protruding portion protruding in a direction away from the back plate.

### Claim 3 (depends on 2)

The electronic device of claim 2, wherein the curved surface comprises a second protruding portion protruding in the direction away from the back plate.

### Claim 4 (depends on 3)

The electronic device of claim 3, wherein the support module further comprises a support unit between the base and the optical film, and the support unit is connected to the base in a position between the first protruding portion and the second protruding portion.

### Claim 5 (depends on 1)

The electronic device of claim 1, wherein the support module further comprises a support unit between the base and the optical film, the support unit is connected to an upper surface of the base, and the upper surface comprises the curved surface.

### Claim 6 (depends on 5)

The electronic device of claim 5, wherein the support unit has a first width at a top position away from the back plate and a second width at a bottom position closer to the back plate, and the second width is greater than the first width.

### Claim 7 (depends on 1)

The electronic device of claim 1, further comprising a reflective sheet disposed on the back plate, wherein the reflective sheet comprises an opening disposed corresponding to the support module.

### Claim 8 (depends on 1)

The electronic device of claim 1, further comprising a light source disposed on the back plate.

### Claim 9 (depends on 8)

The electronic device of claim 8, wherein the light source is disposed in a chamber formed by the optical film and the back plate.

### Claim 10 (depends on 8)

The electronic device of claim 8, wherein a projection of the light source on the back plate and a projection of the support module on the back plate are not overlapped.

### Claim 11 (depends on 1)

The electronic device of claim 1, wherein the hollow space is enclosed by the base.
