In the display assembly 200 provided by some embodiments of the present disclosure, the adjusting device 210 is installed on the back side of the display side of the flexible folding display panel 100, and the angle between the two plane portions 110 of the flexible folding display panel 100 is adjusted by the adjusting device 210, so that polymorphic change of the flexible folding display panel 100 can be realized, when the display assembly 200 is used for vehicle-mounted display, polymorphic auxiliary driving experience can be provided for a driver, and meanwhile, an intelligent interactive viewing angle more suitable for the driving style of the driver can be found for the driver, so that better user viewing experience is provided; moreover, when the external environment changes, the angle between the two planar portions 110 of the flexible folding display panel 100 of the present disclosure can be adjusted by the adjusting device 210, so as to reduce the reflected light and achieve the effect of shadow elimination, so that the user is not easy to feel dazzling and dazzling when watching, and the watching effect of the viewer is improved.

In some embodiments, with reference to fig. 2, the two plane portions 110 connected to the bendable portion 120 are a first plane portion 111 and a second plane portion 112, respectively.

The adjusting device 210 includes: a fixed frame 221, a rotating member 222, a connecting rod 223, a moving member 224, a guide rail 225, and a power source 226.

The fixing frame 211 is attached to the back side of the display side of the first plane part 111. The rotating member 222 is rotatably mounted on the fixing frame 221. One end of the link 223 is fixedly connected to the rotating member 222. And a moving member 224 hinged to the other end of the link 223. And a guide rail 225 attached to the back side of the second flat surface portion 112 on the display side.

Under the driving of the power source 226, the rotating member 222 can rotate clockwise or counterclockwise, and the moving member 224 moves in the extending direction of the guide rail 225 under the driving of the connecting rod 223, so as to drive the second plane portion 112 to rotate clockwise or counterclockwise, thereby adjusting the angle of the second plane portion 112 relative to the first plane portion 111, realizing the multi-form change of the flexible folding display panel 100, providing the driver with multi-form auxiliary driving experience, and finding an intelligent interactive viewing angle more suitable for the driving style of the driver, thereby having better user viewing experience.

In some embodiments, the moving member 224 is a slider or a roller. The sliding block or the roller may be slidably coupled to the guide rail 225, and may reduce a friction force between the moving member 224 and the guide rail 225, so that a relative movement between the moving member 224 and the guide rail 225 is easier.

In some embodiments, with reference to fig. 2, the number of the second flat portions 112 is two, two second flat portions 112 are located at two sides of the first flat portion 111, and the two second flat portions 112 are connected to the first flat portion 111 through a bendable portion 120 respectively.

The number of the adjusting means 210 is two, and one adjusting means 210 is used for adjusting the angle of one second plane part 112 with respect to the first plane part 111.

When the two second flat portions 112 are driven by the adjusting device 210 to rotate clockwise by 30 ° or 60 °, the flexible foldable display panel 100 is in an S-display shape as a whole.

In this example, the number of the second flat portions 112 is two, the number of the adjusting devices 210 is two, and one adjusting device 210 can adjust the angle of one second flat portion 112 relative to the first flat portion 111, so as to implement the multi-configuration change of the flexible foldable display panel 100, and provide the driver with a multi-configuration auxiliary driving experience.

In some embodiments, where two adjustment devices 210 multiplex a single power source 226, the display assembly 200 further includes a power switching device. The power switching device is used for controlling the power source 226 to be connected with any one of the two rotating pieces 222. Thus, the structure of the display module 200 can be simplified, and the cost can be saved.

In some embodiments, continuing to refer to fig. 2, two actuators 210 are multiplexed into a single mounting bracket 221. Thus, the flexible foldable display panel 100 can be changed in various forms, and the structure of the display module 200 can be simplified.

In some embodiments, with reference to fig. 2, one end of the flip chip 20 is electrically connected to the main control circuit board 19, and the other end is bonded to the edge of the second plane portion 112 away from the first plane portion 111. At this time, the display assembly 200 further includes a support member 230. The support member 230 is mounted on the back side of the display side of the second plane portion 112, and the support member 112 is used for supporting the main control circuit board 19.

Therefore, the main control circuit board 19 and the supporting member 230 can be bonded by the thermal insulation adhesive layer 231, and the display effect of the flexible foldable display panel 100 can be prevented from being affected by the heat generated by the adjusting device 210 during the movement process.

For example, the thermal insulation adhesive layer 231 may be an ultraviolet light curing transparent adhesive, which undergoes polymerization and cross-linking reaction under the irradiation of ultraviolet light to change from a liquid state to a solid layer, and may be disposed on one side of the main control circuit board 19 by coating, printing, and the like, and can be firmly attached to one side of the supporting member 230 away from the flexible folding display panel 100, without other fixing structures, thereby simplifying installation.

Therefore, the structure of the display module 200 is more compact, and the moving member 224 can move into the cavity formed between the supporting member 230 and the second plane portion 112, so that the moving member is not deviated to a certain extent, and the overall structure of the display module 200 is more stable.

In some embodiments, referring to fig. 3, fig. 3 is a partial detailed structure diagram of the display assembly 200, an opening pattern 131 is disposed on the support layer 13 of the flexible foldable display panel 100, and an orthogonal projection of the opening pattern 131 on the flexible foldable display panel 100 is at least located on the bendable portion 120.

The opening pattern 131 may be one opening, or may be a plurality of openings arranged in an array, and the shape of the plurality of openings may be any one of a rectangle, a semicircle, a semi-ellipse, a trapezoid, and a triangle, and of course, the shape of the plurality of openings may also be other irregular shapes.

In this embodiment, by providing the opening pattern 131 at least at the bendable portion 120 of the support layer 13, the bending stress of the flexible foldable display panel 100 at the bendable portion 120 can be reduced, and the bending and folding performance of the flexible foldable display panel 100 can be improved.

Based on this, for example, please continue to refer to fig. 3, the orthographic projection of the opening pattern 131 on the flexible foldable display panel 100 is also located in the area d of the planar portion 110 near the bendable portion 120. That is, the opening pattern 131 includes a portion located in the bendable portion 120 and a portion located in the area d of the planar portion 110 beyond the bendable portion 120.

Some embodiments of the present disclosure provide a display assembly 200, which makes the bending performance of the bendable part 120 of the flexible folding display panel 100 better by providing the opening pattern 131 on the support layer 13 of the flexible folding display panel 100, and the opening pattern 131 includes a portion located in the bendable part 120 and a portion located in the region d beyond the bendable part 120 in the planar part 110, thereby making it easier for the display assembly 200 to adjust the angle between two planar parts 110 to which the bendable part 120 is connected.
