Abstract

A display panel and a display device are disclosed. The display panel includes a first sub-panel (1), a second sub-panel (2), a drive unit (4) and an image acquisition unit (3). The first sub-panel (1) has a transparent area (S1) and a display area (S2) surrounding the transparent area (S1). The second sub-panel (2) is on a side of the first sub-panel (1) away from a display surface. The drive unit (4) is connected to the second sub-panel (2) and can drive the second sub-panel (2) to move back and forth between positions corresponding to the transparent area (S1) and the display area (S2) of the first sub-panel (1). The image acquisition unit (3) is on a side of the second sub-panel (2) away from the first sub-panel (1), and an orthographic projection thereof on the first sub-panel (1) is within the transparent area (S1).

First claim

What is claimed is:

1. A display panel, comprising:
a first sub-panel having a transparent area and a display area surrounding the transparent area;
a second sub-panel on a side of the first sub-panel away from a display surface of the first sub-panel;
a drive unit connected to the second sub-panel and capable of driving the second sub-panel to move back and forth between positions respectively corresponding to the transparent area and the display area of the first sub-panel; and
an image acquisition unit on a side of the second sub-panel away from the first sub-panel, an orthographic projection of the image acquisition unit on the first sub-panel being within the transparent area,
wherein the first sub-panel comprises a substrate, a plurality of gate lines and a plurality of data lines on a side of the substrate close to the display surface; wherein
the plurality of gate lines extend along a first direction and are arranged only in the display area;
and/or,
the plurality of data lines extend along a second direction and are arranged only in the display area, and
wherein in a case where the plurality of gate lines are arranged only in the display area, the first sub-panel further comprises a plurality of first bridging lines, and gates lines, which ought to pass through the transparent area, of the plurality of gate lines are each broken at a border between the transparent area and the display area and separated into two parts, and each of the plurality of first bridging lines is arranged in the display area and connects together the two parts into which a gate line corresponding thereto is separated;
and/or
in a case where the plurality of data lines are arranged only in the display area, the first sub-panel further comprises a plurality of second bridging lines, and data lines, which ought to pass through the transparent area, of the plurality of data lines are each broken at a border between the transparent area and the display area and separated into two parts, and each of the plurality of second bridging lines is arranged in the display area and connects together the two parts into which a data line corresponding thereto is separated.

2. The display panel of claim 1 , wherein an area of an orthographic projection of the second sub-panel on the first sub-panel is greater than or equal to an area of the transparent area.

3. The display panel of claim 1 , wherein the transparent area is circular in shape.

4. The display panel of claim 1 , wherein the first sub-panel comprises a substrate, a plurality of gate lines and a plurality of data lines on a side of the substrate close to the display surface; wherein
the plurality of gate lines extend along a first direction and are arranged in the display area and the transparent area;
the plurality of data lines extend along a second direction and are arranged in the display area and the transparent area; and
widths of both the plurality of gate lines and the plurality of data lines are micron-sized.

5. The display panel of claim 1 , wherein in a case where the plurality of gate lines or the plurality of data lines are also arranged in the transparent area, widths of the plurality of gate lines or the plurality of data lines are micron-sized.

6. The display panel of claim 1 , wherein in a case where the plurality of gate lines are arranged only in the display area, the first sub-panel further comprises a first additional layer, the first additional layer is on a side of a layer where the plurality of gate lines are located away from the substrate, the plurality of first bridging lines are in the first additional layer, and each of the plurality of first bridging lines is connected to the two parts of the gate line corresponding thereto through vias in the first additional layer;
and/or,
in a case where the plurality of data lines are arranged only in the display area, the first sub-panel further comprises a second additional layer, the second additional layer is on a side of a layer where the plurality of data lines are located away from the substrate, the plurality of second bridging lines are in the second additional layer, and each of the plurality of second bridging lines is connected to the two parts of the data line corresponding thereto through vias in the second additional layer.

7. A display device, comprising the display panel of claim 1 .

8. The display panel of claim 1 , wherein the drive unit comprises a drive member and a slide assembly; wherein
the slide assembly is fixedly connected with the second sub-panel, the drive member is connected with the slide assembly, and the drive member drives the slide assembly to move back and forth to drive the second sub-panel to move back and forth.

9. The display panel of claim 8 , wherein the drive unit further comprises a fixing assembly; the slide assembly comprises a fixed part and a slide part, the fixed part is a rotating shaft, and the slide part is a sleeve; wherein
the fixing assembly is connected with the second sub-panel, and is configured to fix the second sub-panel and keep the second sub-panel parallel to the first sub-panel;
the sleeve is fixedly connected with the fixing assembly and is sleeved on the rotating shaft, and the drive member is connected with the rotating shaft to drive the rotating shaft to rotate; and
an inner side of the sleeve is provided with threads, a surface of the rotating shaft is provided with threads, the threads of the sleeve are matched with the threads of the rotating shaft, and the sleeve drives the second sub-panel to move back and forth along the rotating shaft when the rotating shaft rotates.

10. The display panel of claim 9 , wherein the fixing assembly comprises a fixing plate and a clamping member; wherein
the second sub-panel is placed and fixed on a side of the fixing plate close to the first sub-panel; and
the clamping member has two slots, the two slots are located on two sides of the fixing plate to clamp and hold the fixing plate between the two slots, and the fixing plate is slideable along the two slots.

11. The display panel of claim 10 , further comprising a frame structure, wherein the clamping member and the drive member are fixed on the frame structure of the display panel.

12. The display panel of claim 8 , further comprising: an determination unit electrically connected to the drive unit and configured to identify an angle between a line of sight of a human eye and the display panel and drive the drive unit to drive the second sub-panel to move according to the angle, so as to adjust a relative position of the second sub-panel to the transparent area.
