Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and apparatus consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic structural diagram of a flexible display screen shown in the embodiment of the present disclosure, and as shown in fig. 1, the flexible display screen includes a CG cover plate layer 10 and an auxiliary layer 11, where the auxiliary layer 11 includes an OCA layer, a POL layer, an Embo glue, a foam layer, and the like, and each layer of material in the auxiliary layer 11 mainly includes a polymer material, so that the display screen is thin and has high flexibility. Since the flexible display is very weak against pressure, when subjected to a large impact force, the broken bright spot area 12 as shown in fig. 2 appears. In this case, the back surface of the display panel is strongly pressed, which may cause damage to the pixel circuit.

Fig. 3 is a schematic view of the arrangement of the foam double-sided adhesive tape of the flexible display screen, as shown in fig. 3, the main reason that the flexible display screen is not pressure-resistant at present is that the foam double-sided adhesive tape 40 is coated only on the left and right sides of the backplane module in the coating manner shown in fig. 3, and the foam double-sided adhesive tape 40 is in a shape of a Chinese character 'men' on the backplane module 20. And the width of the foam double-sided adhesive 40 is extremely narrow, and the proportion of the foam double-sided adhesive to the total area of the backboard module 20 is extremely small, and is basically lower than 5%. Because the width and the total area of the foam double-sided adhesive 40 are relatively small, when the display screen is impacted, such as a steel ball drop test, sufficient buffering cannot be provided, so that local stress of the screen body of the display screen is concentrated, and a broken bright spot area 12 shown in fig. 2 appears.

The display screen of the embodiment of the present disclosure includes:

a back plate module 20;

the display screen body is attached to the first side of the backboard module 20;

the buffer layer is attached to a second side of the back plate module 20, and the second side is opposite to the first side;

the area of the buffer layer covering the second side of the backplane module 20 is greater than or equal to a predetermined ratio. The set ratio here may be 30%, 25%, 15%, 20%, 40%, etc.

Fig. 4 is a schematic diagram illustrating a comparison of an adhesive layer arrangement according to an embodiment of the present disclosure, and fig. 5 is a schematic diagram illustrating a comparison of a protective layer arrangement according to an embodiment of the present disclosure, as shown in fig. 4 and 5, in an embodiment of the present disclosure, the buffer layer includes an adhesive layer 40 and a protective layer 41; compared with the covering area of the arrangement of the foam double-sided adhesive tape 40 shown in fig. 3, the arrangement area of the adhesive layer 40 of the embodiment of the disclosure is significantly increased, and the whole width and area are relatively large. The foam adhesive of the bonding layer 40 at the upper end of the display screen is widened, so that the stress concentration at the upper end of the display screen can be reduced, and the phenomenon of broken bright spots on the screen can not be caused when the display screen is impacted by large force. The adhesive layer 40 is attached to a first area where the camera module on the second side is located, and the adhesive layer 40 covers the whole area of the first area except for related components of the camera module. That is, in order to increase the pressure impact resistance of the display screen, the first area of the second side of the backplane module 20, i.e. the area except the relevant components such as the camera module, is preferably covered by the adhesive layer 40 in a manner of covering as large as possible.

In the embodiment of the present disclosure, the bonding layer 40 still adopts the foam double-sided adhesive tape because the upper end of the display screen is provided with the camera module, and the foam double-sided adhesive tape can play the role of dustproof camera. The cotton double faced adhesive tape of bubble can also carry out waterproofly to the trompil of display screen upper end.

As shown in fig. 5, the protection layer 41 is attached to a second area outside the camera module on a second side of the backplane module 20, wherein the protection layer at least covers two sides of the second side.

In the embodiment of the present disclosure, as shown in fig. 4 and 5, the second area and the first area are areas respectively located at the lower end and the upper end of the second side of the backplane module 20. The protective layer 41 is a foam layer. The protective layer 41 preferably covers the entire second area, irrespective of cost. Specifically, in the embodiment of the present disclosure, the right and left distributed door-shaped foam glue shown in fig. 3 is changed into the whole foam, and the thickness of the foam layer, i.e., the protective layer 41, may be greater than or equal to 0.15 mm. Therefore, the total thickness of the foam layer in the display screen body and the foam layer of the protective layer 41 is more than or equal to 0.25mm, and the foam thickness is preferably directly abutted against the shell of the display screen.

As an implementation manner, the protection layer 41 covers the entire second area of the second side of the backplane module 20, and extends beyond the first dimension to two sides of the second area. The first dimension here may be 0.1 mm. After the protection layer 41 extends beyond the two sides of the backplane module 20, the edge of the backplane module 20 can be protected accordingly.

As an implementation manner, the thickness of the protection layer 41 is greater than or equal to the second size, where the second size may be 0.15 mm. As shown in fig. 5, the protective layer 41 is further provided with an air vent 42. The foam protective layer 41 is uniformly provided with a plurality of rows of exhaust holes 42, so that the foam protective layer 41 is prevented from being locally bulged when being attached to the second area on the second side of the back plate module 20. In the embodiment of the present disclosure, the aperture of the exhaust hole 42 is about 2 mm.

As shown in fig. 5, a first gap 43 is left between the protective layer 41 and the adhesive layer 40; the first gap 43 is equal to or smaller than the third dimension. The third dimension here may be 0.8 mm.

In the embodiment of the present disclosure, the display screen further includes a housing; the adhesive layer 40 and the protective layer 41 are bonded to the housing by adhesive glue. The foam protective layer 41 is adhered to the shell through adhesive glue, and the foam protective layer 41 is attached to the inside of the shell. The adhesive glue may be a grid glue (Embo glue). When the foam protective layer 41 is attached, air is removed through the air vent 42 to prevent local swelling.

Fig. 6 is a schematic diagram of a protective layer locally disposed on the backplane module shown in the embodiment of the present disclosure, and as shown in fig. 6, in order to reduce the cost of the display screen, the second side of the backplane module 20 adopts a full-face foam mode to increase the cost, and in order to reduce the cost, the protective layer covering the whole second area can be changed to adopt a strip-shaped foam structure on the two sides of the second area, and the width is about 10mm, so that the cost can be saved by more than half. Even if the mode of locally setting the protection layer 41 is adopted, the display screen can be well protected, because the risk of the broken bright spots close to the edge part of the display screen is higher, and the risk of the broken bright spots at the middle position is low, therefore, even if the mode of locally setting the protection layer 41 shown in fig. 6 is adopted, the protection effect on the display screen can also be realized.

In the embodiment of the present disclosure, in order to facilitate assembling the backplane module of the present disclosure in the housing, a second gap is left between the portions of the protection layer 41 of the foam at the two sides of the second region and the inner walls at the left and right sides of the housing, where the second gap is about 0.3mm, and specifically, the second gap may be 0.25-0.4 mm.
