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.

First claim

What is claimed is:

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.

2. 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.

3. 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.

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

5. 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.

6. 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.

7. 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.

8. 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.

9. 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.

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