Before bending (or folding), when the contents displayed in the first planar display area 110a and the second planar display area 110b are the same, the actual display area is increased to meet the requirement of the client for large-area planar display; when the contents displayed by the first flat display area 110a and the second flat display area 110b are different, the split-screen display function is realized, and the requirement of the client for the simultaneous use of a plurality of applications can be met.
After the bending, when the contents displayed in the first planar display area 110a and the second planar display area 110b are the same, the requirement that multiple people watch the same display content at the same time is met; when the contents displayed by the first flat display area 110a and the second flat display area 110b are different, which is equivalent to realizing split-screen display, the requirement of a client for simultaneously using a plurality of applications and the requirement of a plurality of people watching different applications of the same display device can be met.

The shape memory alloy has shape memory effect (shape memory effect) and pseudo elasticity (hyperelasticity), and is characterized in that under the action of external force, the shape memory alloy has much larger deformation recovery capability than that of common metal, namely, large strain generated in the loading process can be recovered along with unloading, so that the bending times of bending can be greatly increased when the shape memory material is used as the material of a bending area, the service life of a display panel is prolonged, and the like.
As shown in fig. 2 and fig. 3, the display panel 1 further includes a bonding area 300, where the bonding area 300 is used to bond the flexible circuit board 32, the flexible circuit board 32 is located in the flexible circuit board placement area 3 (see fig. 5 or fig. 6), that is, the flexible circuit board placement area 3 is located on the back of the display panel 1, that is, on the back of the non-bending display area 100, as the name implies, the flexible circuit board placement area 3 is used to place the flexible circuit board 32, and a fixing plate 31 is also provided, where the fixing plate 31 is located on the back of the display panel 1, that is, on the back of the non-bending display area 100, and one end of the fixing plate 31 is located in a cavity formed after the static bending display area 210 is bent, and the cavity is the bonding area 300. The fixed plate 31 is a hard substrate and has good fixing and supporting functions, and the flexible circuit board 32 is fixed on the fixed plate 31 and bonded to the static bending display area 210 through the bonding area 300, so that functions of electrifying and displaying of the display area are guaranteed.

The dynamic bending display area and the static bending display area are arranged together, so that the bending process in the original bonding process of the flexible circuit board is omitted, and the yield of the manufacturing process of the display panel is improved. The dynamic bending display area can be folded inwards or outwards, can meet the requirements of a large-screen display panel, small space occupation and the like, and has great market potential.
