Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. In the drawings, the size and thickness of components illustrated in the drawings are not to scale for clarity and ease of understanding and description.
As shown in fig. 1, a basic structure diagram of an OLED display device provided in an embodiment of the present invention is provided, the OLED display device includes an OLED display panel 10, a support assembly 20, and a cover plate 30, the OLED display panel 10 includes a first planar area A1, a second planar area A2, and a bending area A3 connecting the first planar area A1 and the second planar area A2, the bending area A3 includes an arc area a31 and a slip transition area a32; two sides of the supporting component 20 are respectively attached to the backlight side of the OLED display panel 10 in the first planar area A1 and the OLED display panel 10 in the second planar area A2; the cover plate 30 is located at the light emitting side of the OLED display panel 10 of the first planar area A1; wherein a supporting plate 40 is disposed on a side of the OLED display panel 10 of the second planar area A2 away from the supporting component 20, and the supporting plate 40 cooperates with the cover plate 30 to make the sliding transition area a32 coplanar with the first planar area A1 and/or the second planar area A2.
It can be understood that, the flexible display device bending outward can generate a certain film layer dislocation in the bending process, and the junction of the bending area and the plane area is excessively bent to exceed the bearing limit of the metal wiring in the panel due to the traction force of each film layer dislocation, so that the display is very easy to break, and the display is poor. According to the invention, the bendable sliding transition area A32 is added between the second plane area A2 and the arc area A31, when the film layer is dislocated due to the dynamic bending of the OLED display device, the arc area A31 also slides due to the action of dislocated traction force, the sliding transition area A32 has the bending performance and can synchronously slide and roll along with the arc area A31, and the two ends of the bending area A3 are limited due to the combined action of the cover plate 30 and the support plate 40, so that the arc area A31 always keeps a bending semi-circular arc, and the occurrence of poor display caused by the breakage of the film layer due to the overlarge deformation of the arc area A31 is avoided.
It should be noted that, in a state where the OLED display device is flattened, the slip transition area a32 is located between the second planar area A2 and the arc-shaped area a31 (that is, the slip transition area a32 is coplanar with the second planar area A2), when the OLED display device is bent outward, the slip transition area a32 may be rolled synchronously with the arc-shaped area a31, at this time, a part or all of the slip transition area a32 located between the second planar area A2 and the arc-shaped area a31 may be rolled to the arc-shaped area a31 as a component of the arc-shaped area a31, and an excess part of the arc-shaped area a31 before being bent, which is close to the first planar area A1, may be rolled to a plane coplanar with the first planar area A1 as a component of the slip transition area a 32. Wherein, because the interval between apron 30 and the backup pad 40 is unchangeable, has restricted promptly arc district A31's radius of buckling has restricted arc district A31's arc length, consequently, can be so that in the process of buckling, arc district A31 keeps having one section semicircle all the time, can not lead to arc district A31's deformation too big.
It should be noted that, the orthographic projections of the cover plate 30 and the support plate 40 on the OLED display panel 10 both overlap the arc-shaped area a31, so that the cover plate 30 and the support plate 40 cooperate to limit the arc length of the arc-shaped area a31, and the slip transition area a32 is coplanar with the first planar area A1 and/or the second planar area A2.
In one embodiment, the support assembly 20 includes a first support layer 201, a buffer layer 202, a backing plate 203, a stiffener 205, and a second support layer 206; the first supporting layer 201 is attached to the OLED display panel 10 located in the first planar area A1; the buffer layer 202 is positioned on a side surface of the first support layer 201 away from the OLED display panel 10; the back plate 203 is positioned on one side surface of the buffer layer 202 away from the first support layer 201; the reinforcing plate 205 is positioned on the side of the back plate 203 far away from the buffer layer 202; the second supporting layer 206 is located on a side of the reinforcing plate 205 away from the back plate 203 and attached to the OLED display panel 10 of the second planar area A2.
The buffer layer 202 can be made of foam, the foam has high elasticity, and the buffer effect is good. The back plate 203 is a steel sheet, so that the overall stiffness and flatness of the OLED display panel 10 can be improved, and the use hand feeling of a user can be improved. One side of the reinforcing plate 205 close to the back plate 203 is adhered to the back plate 203 through a grid rubber layer 204.
In one embodiment, an end of the reinforcing plate 205 near the bending area A3 is provided with a notch. It should be noted that, because the sliding transition area a32 slides and rolls to the arc area a31 in the dynamic bending process, a support layer is not arranged inside the sliding transition area a32 in the present invention, so as to avoid affecting the deformation of the sliding transition area a32, in this embodiment, a notch is arranged at one end of the reinforcing plate 205 close to the bending area A3, so as to reserve an avoidance space for the sliding transition area a32, thereby avoiding affecting the deformation of the sliding transition area a 32.
In one embodiment, the length W1 of the slip transition area a32 is greater than or equal to 0.2 mm and less than or equal to 1 mm, where the length W1 refers to the sum of the shortest distance from the first planar area A1 to the arc area a31 and the shortest distance from the second planar area A2 to the arc area a 31. The bending radius R of the arc-shaped area A31 is greater than or equal to 0.2 mm and less than 0.25 mm. Wherein the bending radius R of the arc-shaped area a31 is set by adjusting the interval between the cover plate 30 and the support plate 40.
In one embodiment, the material of the supporting plate 40 is any one of polyethylene terephthalate, rubber, and metal sheet, and may be other materials with higher hardness. The support plate 40 is arranged outside the sliding transition area A32 to provide certain structural support, so that the ultimate bending radius R of the arc area A31 is approximately equal to 0.2 mm, and the sliding transition area A32 and the second plane area A2 are coplanar.
In one embodiment, an end of the supporting plate 40 away from the bending area A3 is adhered to the OLED display panel 10 located in the second planar area A2 by a pressure sensitive adhesive layer 50.

In one embodiment, the material of the protective layer 60 is an ultraviolet light curable adhesive.
It can be understood that, the protective layer 60 is attached to the outer surface of the OLED display panel 10, one end of the protective layer is abutted to the supporting plate 40, the other end of the protective layer is abutted to the cover plate 30, and the shape of the protective layer 60 is limited to enable the bending area A3 of the OLED display panel to have the same shape, so as to avoid the cover plate 30 and the supporting plate 40 directly contacting the OLED display panel 10 to scratch the OLED display panel 10 and cause poor display.
It should be noted that the orthographic projection of the protection layer 60 on the OLED display panel 10 overlaps with both the first planar area A1 and the second planar area A2, so as to protect the OLED display panel 10 of the bending area A3.
In an embodiment, the OLED display device further includes a chip on film 70 located on a side of the second planar area A2 away from the bending area A3 and electrically connected to the OLED display panel 10, a driving chip 80 electrically connected to the chip on film 70, and a polarizing layer 90 located between the cover plate 30 and the OLED display panel 10 of the first planar area A1. The driving chip 80 transmits a driving signal to the OLED display panel 10 through the chip on film 70, and the polarization layer 90 is used for reducing the reflectivity of the OLED display panel 10.

Wherein, a supporting plate 40 is disposed on a side of the OLED display panel 10 of the second planar area A2 away from the supporting assembly 20. When the OLED display device is bent outward by 180 degrees, the film layer is dislocated, the sliding transition area a32 is completely rolled to the arc area a31 to be a component of the arc area a31, and an excess portion of the arc area a31 before bending, which is close to the first planar area A1, is slid to a plane coplanar with the first planar area A1 to be a component of the sliding transition area a 32. Due to the fact that the supporting plate 40 and the cover plate 30 are limited in a coaction mode, the sliding transition area A32 and the first plane area A1 are coplanar, the arc area A31 is always kept with a section of semicircular arc, and deformation of the arc area A31 cannot be too large.

One side of the reinforcing plate 205 close to the back plate 203 is adhered to the back plate 203 through a grid rubber layer 204.

Wherein, a supporting plate 40 is disposed on a side of the OLED display panel 10 of the second planar area A2 away from the supporting component 20. When the OLED display device is bent outward by 135 degrees (or any value greater than 0 degrees and less than 180 degrees), the film layers are misaligned, a part of the slip transition area a32 slides and rolls to the arc area a31 as a component of the arc area a31, and an excess part of the arc area a31 before bending, which is close to the first planar area A1, slides to a plane coplanar with the first planar area A1 and serves as a component of the slip transition area a 32.
