Referring to fig. 1, in some display modules, the edges of the flat flexible screen body need to be turned and bent into curved surfaces, so as to form a flat display area 910 in the middle and a curved display area 920 at the edges. However, the curved display area 920 may have a large stereoscopic shape change when the curved display area 920 is converted from a flat surface to a curved surface, and thus wrinkles may be easily generated in the curved display area 920. Especially, in the display module having a circular planar area, each position of the curved area is greatly deformed in the direction surrounding the planar display area 910, and there is a great risk of wrinkles.
In view of this, the present invention provides a solution that can reduce the risk of generating wrinkles in the curved surface area, and the solution provided by the present embodiment is described in detail below.
Referring to fig. 2, fig. 2 is a schematic plane expanded view of a display module, where the display module includes a first screen body 110 and a second screen body 120. Optionally, the first screen body 110 and the second screen body 120 are OLED flexible display screens (OLED flexible displays).
The second screen 120 is in a shape of a strip having an arc, the second screen 120 includes at least a part of a break 121, and the break 121 is electrically isolated from the first screen 110. That is, the cut-off portion 121 of the second panel 120 may be separated from the first panel 110 without being attached to the light-transmissive cover 200.
Referring to fig. 3, in the attaching process, the cut-off portion 121 of the second panel 120 may be bent in a direction away from the light-emitting surface of the first panel 110, and a side surface of the cut-off portion 121 is attached to a side surface of the first panel 110, so that the cut-off portion 121 and the first panel 110 are joined together to form a shape as shown in fig. 4 and 5.
Referring to fig. 4 and 5, after the bonding, the second screen 120 surrounds at least a portion of the first screen 110. Referring to fig. 6 again, fig. 6 isbase:Sub>A cross-sectional view taken along the directionbase:Sub>A-base:Sub>A shown in fig. 4, after the bonding,base:Sub>A section of the second screen 120 away from the first screen can be bent tobase:Sub>A side of the first screen 110 away from the light-emitting surface, so as to formbase:Sub>A curved portion withbase:Sub>A radian edge. In this embodiment, the first screen body 110 may correspond to a flat display area 910 of a display module, and the second screen body 120 may correspond to a curved display area 920 of the display module.

The disconnecting portion 121 is electrically connected to the connecting portion 122. For example, the disconnection portion 121, the connection portion 122, and the array substrate of the first panel 110 are a connected whole, so that the first panel 110 and the second panel 120 can be driven simultaneously as a whole.
Optionally, referring to fig. 7 or 8, the first screen 110 or the second screen 120 includes a first bonding portion 131, and the first bonding portion 131 is used for electrically connecting with other circuits.

Optionally, referring to fig. 7 again, the second screen 120 includes two breaking portions 121, and the two breaking portions 121 are symmetrically distributed with respect to the connecting portion 122. In this way, when the second panel 120 and the first panel 110 are attached to each other, the two cut portions 121 may be attached to the side edges of the first panel 110, respectively, so as to reduce the risk of errors occurring in the attachment.
In another possible implementation manner, referring to fig. 9, the first screen 110 and the second screen 120 may be two relatively independent screens, and the first screen 110 and the second screen 120 are electrically isolated from each other. In this case, the first panel 110 includes a second bonding portion 132, the second panel 120 further includes a third bonding portion 133, and the second bonding portion 132 and the third bonding portion 133 are electrically connected to other circuits. For example, the second bonding part 132 and the third bonding part 133 may include bonding fingers or pads electrically connected to other circuits. The first panel 110 and the second panel 120 may be driven to display by the second bonding part 132 and the third bonding part 133 relatively independently.
In a possible implementation manner, in a planar spreading state, the light-emitting surface of the first screen body 110 is circular, and the planar spreading pattern of the light-emitting surface of the second screen body 120 is a fan ring. Optionally, the display angle of the second screen body 120 after being attached can be adjusted by setting the fan ring angle of the second screen body 120. Specifically, referring to fig. 11, a fan ring angle of the second screen 120 is R1, and referring to fig. 13, a display angle of the second screen after the second screen 120 is attached to the first screen 110 is R2, where R2= arccos (R1/2 pi).
It should be noted that in other implementation manners of the present application, the first screen body 110 may also have other shapes, such as an oval shape, a polygonal shape, or other irregular shapes, and the second screen body 120 may have a belt-shaped structure with a shape after being attached to the first screen body 110, which is not described herein again.
In a possible implementation manner, referring to fig. 13, the display module further includes a light-transmitting cover plate 200 covering light-emitting surfaces of the first screen body 110 and the second screen body 120, where the light-transmitting cover plate 200 includes a planar area corresponding to the first screen body 110 and a curved area corresponding to the second screen body 120.

After the display module to be attached and the alignment mark on the attachment jig 300 are aligned, the first screen 110 of the display module to be attached is adsorbed by the vacuum adsorption device on the attachment jig 300. And then the second screen body 120 is drawn to the alignment groove of the curved pushing part of the bonding jig 300 through the traction films attached to the two ends of the second screen body.
Step S130, the display module to be bonded is pushed and pressed by the bonding jig 300 to be bonded with the transparent cover plate 200.
The light-transmitting cover plate 200 includes a planar area corresponding to the first screen 110 and a curved area corresponding to the second screen 120. Referring to fig. 14, the display module to be bonded is driven by controlling the bonding jig 300 to move toward the transparent cover plate 200, so that the display module to be bonded can be pushed to be bonded with the transparent cover plate 200.
Step S140, removing the attaching jig 300 from the attached display module.
