Abstract

A display module and a display device are provided. The display device includes a display panel, a fixing member, and a control unit. The display panel includes a first display region and a second display region connected by a bending region. The fixing member fixes the second display region and guides the second display region corresponding to the first display region to move. Furthermore, a first via hole is formed in an electronic element disposing region of the display panel. Because of the first via hole on the display panel, an electronic element such as a camera, etc. is disposed under the display panel to realize full screen technology such as an under-display camera, etc. Meanwhile, because of the second display region, it can be realized that a region corresponding to the first via hole can still functionally display when the electronic elements are not in operation.

First claim

What is claimed is:

1. A display module, comprising:
a display panel comprising a first display region and a second display region connected by a bending region;
a fixing member used to fix the second display region and guiding the second display region corresponding to the first display region to move;
wherein a first via hole is formed in an electronic element disposing region of the display panel, at least part of the first display region is in contact with the electronic element disposing region, and a display area of the second display region is not less than an area of the electronic element disposing region and is fixed on the fixing member by the bending region after it is bent.

2. The display module as claimed in claim 1 , wherein the fixing member comprises a fixing chute and a pushing/pulling mechanism, the second display region is fixed in the fixing chute, and the pushing/pulling mechanism is used to push or pull the second display region to guide the second display region corresponding to the first display region to move.

3. The display module as claimed in claim 1 , wherein the fixing member comprises a first supporting shaft and a second supporting shaft, the second display region is fixed on the first supporting shaft and the second supporting shaft, and the first supporting shaft rotates and the second supporting shaft translates to guide the second display region corresponding to the first display region to move.

4. The display module as claimed in claim 3 , wherein the first supporting shaft is connected to the second display region by a transparent film material.

5. The display module as claimed in claim 3 , wherein a second via hole is formed on the bending region of the display panel.

6. The display module as claimed in claim 1 , wherein a signal line connected to the second display region is disposed on an edge of the bending region.

7. The display module as claimed in claim 6 , wherein the signal line comprises at least one of a gate scanning line, a data line, a power line, or a grounding line.

8. The display module as claimed in claim 1 , wherein a first alignment mark is disposed on the first display region, and a second alignment mark is disposed on the second display region.

9. The display module as claimed in claim 8 , wherein the first alignment mark comprises a first display alignment terminal and a first non-display alignment terminal, and the second alignment mark comprises a second display alignment terminal and a second non-display alignment terminal.

10. A display device, comprising an electronic element and a display module, wherein the display module comprises:
a display panel comprising a first display region and a second display region connected by a bending region, a first via hole formed in an electronic element disposing region of the display panel, at least part of the first display region in contact with the electronic element disposing region, and a display area of the second display region which is not less than an area of the electronic element disposing region; and
a fixing member used to fix the second display region and guiding the second display region corresponding to the first display region to move, wherein the second display region is fixed on the fixing member by the bending region after it is bent;
wherein the electronic element is disposed under the first display region and the second display region, and
wherein when the electronic element is working, the fixing member guides the second display region corresponding to the first display region to move to expose the first via hole, and when the electronic element is not working, the fixing member guides the second display region corresponding to the first display region to move to cover the first via hole and controls the second display region to work.
