## Abstract

The present invention provides a panel device for the under-display camera. The panel device includes a display panel, a backlight module, a light guiding member, and a light source member. The backlight module is provided with a first opening. The light guiding member is inserted into the first opening for guiding light entering the light guiding member to a display panel area corresponding to the first opening. The light source member provides a light source for the light guiding member. The light source member is turned off when the under-display camera is turned on, and the light source member is turned on or off when the under-display camera is turned off. Therefore, a through hole or a blind hole on the display panel can be re-displayed, and the image quality that can be obtained by the under-display camera is still maintained.

## Claims

### Claim 1

A panel device for an under-display camera, comprising:
a display panel;
a backlight module disposed at one side of the display panel, and provided with a first opening at a position corresponding to the under-display camera;
a light guiding member inserted in the first opening for guiding light entering the light guiding member to a display panel area corresponding to the first opening; and
a light source member for providing a light source for the light guiding member.

### Claim 2 (depends on 1)

The panel device for the under-display camera as claimed in claim 1, wherein the light guiding member is provided with a second opening at a position corresponding to the under-display camera, and a corresponding position to the light guiding member and the light source member is provided with a light incident surface, a light emitting surface is disposed on an inner wall of the second opening, and an angle between the light emitting surface and the light incident surface is an acute angle.

### Claim 3 (depends on 2)

The panel device for the under-display camera as claimed in claim 2, wherein a light blocking film is disposed between the backlight module and the light guiding member, and the light incident surface is disposed at one end of the light guiding member.

### Claim 4 (depends on 1)

The panel device for the under-display camera as claimed in claim 1, wherein the light guiding member is a light guiding ring.

### Claim 5 (depends on 1)

The panel device for the under-display camera as claimed in claim 1, wherein the panel device further comprises a control component electrically connected to the under-display camera and the light source member, respectively, for controlling the light source member to be turned off when the under-display camera is turned on, and controlling the light source member to be turned on or off when the under-display camera is turned off.

### Claim 6 (depends on 1)

The panel device for the under-display camera as claimed in claim 1, wherein the light source member is a light emitting diode (LED) light source or a mini LED light source.

### Claim 7 (depends on 1)

The panel device for the under-display camera as claimed in claim 1, wherein the light guiding member is made of a transparent material or a matte material.

### Claim 8 (depends on 1)

The panel device for the under-display camera as claimed in claim 1, wherein the display panel is a display panel having a through hole or a blind hole.

### Claim 9 (depends on 1)

The panel device for the under-display camera as claimed in claim 1, wherein the backlight module has a back plate as a back surface.

### Claim 10 (depends on 1)
