The method for forming the curved screen with the above structure will be described below.

First, the manufacturing method of the curved screen is described in detail by taking the curved screen 10 of the previous embodiment as an example. It can be understood that the manufacturing method can be referred to for the curved screens 20 and 30 with similar shapes.

Please refer to FIG. 8 , which is a schematic flowchart of a method for manufacturing a curved screen provided by an embodiment of the present application. The manufacturing method of this embodiment comprises the following steps:

Step 101 : providing a curved substrate 12 , and disposing the adhesive 20 on the inner surface of the curved substrate 12 .

The material of the adhesive 20 may be transparent optical adhesive, such as OCA (Optically Clear Adhesive) optical adhesive, which includes two types of resistive type and capacitive type. Of course, the material of the adhesive can also be other, as long as it is transparent and has adhesiveness.

Specifically, this step is to coat the transparent optical adhesive 20 on the inner surface of the curved substrate 12 .

Step 102 : Roll the flexible screen 11 and place it at least partially inside the curved substrate 12 .

Specifically, the flexible screen 11 is wound into a bundle shape, and at least part of the width of the flexible screen 11 is smaller than that of the opening 100 . Then, it is put into the inner side of the curved substrate 12 .

Further, after the flexible screen 11 is placed inside the curved substrate, at least one part of the flexible screen is fixed on the inner surface of the curved substrate.

As a result, the pressing can be started at a fixed position, and the matching accuracy of the curved substrate 12 of the rear flexible screen 11 after pressing can be improved.

Step 103: Put the pressing member 13 into the inner side of the flexible screen 11, and press the flexible screen 11 to the inner surface of the curved substrate 12 by sequentially moving the pressing member 13, so that the flexible screen 11 is connected to the curved substrate through the adhesive 20. 12 is bonded to the inner surface.

Wherein, the pressing member 13 can be a roller. Roll the roller 13 at a fixed position to apply pressure to stick the flexible screen 11 on the inner surface of the curved substrate 12 .

The radius of the roller 13 is smaller than the bending radius of the first connecting portion 123 , thereby ensuring that the roller 13 can fully fit with the first connecting portion 123 when rolling on the inner surface of the first connecting portion 123 . The probability of foaming of the flexible screen 11 is reduced.

In order to improve the stability, the pressing can be performed by rolling the roller 13 several times.

Please refer to FIG. 9 and FIG. 10 , FIG. 9 is a schematic flowchart of another method for manufacturing a curved screen provided by an embodiment of the present application, and FIG. 10 is a process flow diagram corresponding to the manufacturing method shown in FIG. 9 .

Step 201 : providing a curved substrate 12 , and disposing the adhesive 20 on the inner surface of the curved substrate 12 .

The material of the adhesive 20 may be transparent optical adhesive, such as OCA (Optically Clear Adhesive) optical adhesive, which includes two types of resistive type and capacitive type. Of course, the material of the adhesive can also be other, as long as it is transparent and has adhesiveness.

Specifically, this step is to coat the transparent optical adhesive 20 on the inner surface of the curved substrate 12 .

Step 202 : Roll the flexible screen 11 and place it inside the curved substrate 12 , and fix one position of one side of the flexible screen 11 on the inner surface of one of the openings 100 of the curved substrate 12 .

Specifically, the flexible screen 11 is wound into a bundle shape, the width of which is smaller than that of the opening 100 , and the length is smaller than that of the first main body portion 121 . Then the whole bundle is placed inside the curved substrate 12 .

As shown in FIG. 10 , the corner position of one side of the outermost layer of the bundled flexible screen 11 is fixed to the corresponding end corner position of the second main body portion 122 of the curved substrate 12 , and the end corner position is located at the opening 100 . s position.

Of course, the corner position of one side of the outermost layer of the bundled flexible screen 11 can also be fixed at the corresponding end corner position of the first main body portion 121 of the curved substrate 12 , and the end corner position is located at the position of the opening 100 . .

In this way, pressing in one direction can be performed from the position of the opening 100 , which is convenient for pressing. In addition, fixing one position of the outermost end in this embodiment also omits the operation of calculating the length and width of the flexible screen when fixing at other positions.

Step 103: Put the pressing member 13 into the inner side of the flexible screen 11, and press the flexible screen 11 to the inner surface of the curved substrate 12 by sequentially moving the pressing member 13, so that the flexible screen 11 is connected to the curved substrate through the adhesive 20. 12 is bonded to the inner surface.

Wherein, the pressing member 13 can be a roller. Start rolling the roller 13 at a fixed position to apply pressure to stick the flexible screen on the inner surface of the curved substrate.

As shown in FIG. 10 , the drum 13 starts to roll in the direction of the first connecting portion 123 at the fixed position of the opening 100 . The bundle-shaped flexible screen 11 is rotated while rolling the roller 13 , so that the roller 13 can press the flexible screen 11 to the inner surface of the curved substrate 12 .

The radius of the roller 13 is smaller than the bending radius of the first connecting portion 123 , thereby ensuring that the roller 13 can fully fit with the first connecting portion 123 when rolling on the inner surface of the first connecting portion 123 . The probability of foaming of the flexible screen 11 is reduced.

Please refer to FIG. 11 and FIG. 12 , FIG. 11 is a schematic flowchart of another method for manufacturing a curved screen provided by an embodiment of the present application, and FIG. 12 is a process flow diagram corresponding to the manufacturing method shown in FIG. 11 .

Step 301 : providing a curved substrate 12 , and disposing the adhesive 20 on the inner surface of the curved substrate 12 .

The material of the adhesive 20 may be transparent optical adhesive, such as OCA (Optically Clear Adhesive) optical adhesive, which includes two types of resistive type and capacitive type. Of course, the material of the adhesive can also be other, as long as it is transparent and adhesive.

Specifically, this step is to coat the transparent optical adhesive 20 on the inner surface of the curved substrate 12 .

Step 302 : winding the flexible screen 11 and placing it inside the curved substrate 12 , and fixing the middle position of the flexible screen 11 at the corresponding middle position of the curved substrate 12 , wherein the middle position corresponding to the curved substrate 12 is staggered from the opening 100 .

Specifically, the flexible screen 11 is wound into a bundle shape, the width of which is smaller than that of the opening 100 , and the length is smaller than that of the first main body portion 121 . Then the whole bundle is placed inside the curved substrate 12 .

Before the flexible screen 11 is placed inside the curved substrate 12 , the central position of the flexible screen 11 and the corresponding central position of the curved substrate 12 are calculated and marked. Then, after placing the bundled flexible screen 11 inside the curved substrate 12, the two marked positions are directly aligned and fixed.

As shown in FIG. 12 , the center position of the flexible screen 11 is marked, and the center position of the first connecting portion 123 is marked. After the flexible screen 11 is placed inside the curved substrate 12 , the two positions of the mark are aligned and fixed by the transparent optical glue 20 .

The solution of fixing the central position can shorten the one-time pressing distance in step 303, thereby improving the accuracy of pressing.

Step 303: Put the pressing member 13 into the inner side of the flexible screen 11, and press the flexible screen 11 to the inner surface of the curved substrate 12 by sequentially moving the pressing member 13, so that the flexible screen 11 is connected to the curved substrate through the adhesive 20. 12 is bonded to the inner surface.

Wherein, the pressing member 13 can be a roller. Roll the roller 13 at a fixed position to apply pressure to stick the flexible screen on the inner surface of the curved substrate.

As shown in FIG. 12 , the drum 13 first starts to roll in the direction of the first main body portion 121 at the center position of the first connecting portion 123 , that is, the fixed position. The roller 13 can press the flexible screen 11 to the inner surface of the first main body part 121 of the curved substrate 12 . Then, the drum 13 starts to roll again toward the direction of the second main body portion 122 at the central position of the first connecting portion 123 , that is, the fixed position. The roller 13 can press the flexible screen 11 to the inner surface of the second main body part 122 of the curved substrate 12 .

By rolling twice in different directions, the flexible screen 11 can be pasted. In this embodiment, since the one-time rolling distance of the roller 13 is reduced, the matching degree of the flexible screen 11 and the curved substrate 12 is higher.

The radius of the roller 13 is smaller than the bending radius of the first connecting portion 123 , thereby ensuring that the roller 13 can fully fit with the first connecting portion 123 when rolling on the inner surface of the first connecting portion 123 . The probability of foaming of the flexible screen 11 is reduced.

Please refer to FIG. 13 and FIG. 14 , FIG. 13 is a schematic flowchart of another method for manufacturing a curved screen provided by an embodiment of the present application, and FIG. 14 is a process flow diagram corresponding to the manufacturing method shown in FIG. 13 .

Step 401 : providing a curved substrate 12 , and disposing the adhesive 20 on the inner surface of the curved substrate 12 .

The material of the adhesive 20 may be transparent optical adhesive, such as OCA (Optically Clear Adhesive) optical adhesive, which includes two types of resistive type and capacitive type. Of course, the material of the adhesive can also be other, as long as it is transparent and has adhesiveness.

Specifically, this step is to coat the transparent optical adhesive 20 on the inner surface of the curved substrate 12 .

Step 402 : Put the wound part of the flexible screen 11 into the inner side of the curved substrate 12 , and fix one position of one side of the flexible screen 11 on the inner surface of one of the openings 100 of the curved substrate 12 .

Specifically, the flexible screen 11 is wound into a bundle shape, the width of which is smaller than that of the opening 100 , and the length is smaller than that of the first main body portion 121 . Then part of it is placed inside the curved substrate 12 and part is placed outside the opening 100 , so as to prevent the flexible screen 11 from being pasted with the transparent optical glue 20 before being pressed, thereby affecting the accuracy of pressing.

In this embodiment, the width outside the opening 100 of the bundled structure formed by the flexible screen 11 may also be greater than the size of the opening 100 , and the length may also be greater than the length of the first main body portion 121 .

As shown in FIG. 14 , the corner position of one side of the outermost layer of the bundled flexible screen 11 is fixed to the corresponding end corner position of the second main body portion 122 of the curved substrate 12 , and the end corner position is located at the opening 100 . s position.

Of course, the corner position of one side of the outermost layer of the bundled flexible screen 11 can also be fixed at the corresponding end corner position of the first main body portion 121 of the curved substrate 12 , and the end corner position is located at the position of the opening 100 . .

In this way, pressing in one direction can be performed from the position of the opening 100, which is convenient for pressing. In addition, fixing one position of the outermost end in this embodiment also omits the operation of calculating the length and width of the flexible screen when fixing at other positions.

Step 403: Put the pressing member 13 into the inner side of the flexible screen 11, and press the flexible screen 11 to the inner surface of the curved substrate 12 by sequentially moving the pressing member 13, so that the flexible screen 11 is connected to the curved substrate through the adhesive 20. 12 is bonded to the inner surface.

Wherein, the pressing member 13 can be a roller. Roll the roller 13 at a fixed position to apply pressure to stick the flexible screen on the inner surface of the curved substrate.

As shown in FIG. 14 , the drum 13 starts to roll in the direction of the first connecting portion 123 at the fixed position of the opening 100 . And the bundle-shaped flexible screen 11 is rotated while rolling the roller 13 , so that the roller 13 can press the flexible screen 11 to the inner surface of the curved substrate 12 .

The radius of the roller 13 is smaller than the bending radius of the first connecting portion 123 , thereby ensuring that the roller 13 can fully fit with the first connecting portion 123 when rolling on the inner surface of the first connecting portion 123 . The probability of foaming of the flexible screen 11 is reduced.

The above describes the manufacturing method of a curved screen with a flexible screen provided on a curved substrate with openings. The following will introduce the manufacturing method of a curved screen with a flexible screen provided on a curved substrate with a closed circumferential surface.

Specifically, the above-mentioned curved screen 40 is taken as an example for detailed description.

Please refer to FIG. 15 and FIG. 16 together. FIG. 15 is a schematic flowchart of another method for manufacturing a curved screen provided by an embodiment of the present application, and FIG. 16 is a process flow diagram corresponding to the manufacturing method shown in FIG. 15 .

Step 501 : providing a curved substrate 42 , and disposing the adhesive 20 on the inner surface of the curved substrate 42 .

The material of the adhesive 20 may be transparent optical adhesive, such as OCA (Optically Clear Adhesive) optical adhesive, which includes two types of resistive type and capacitive type. Of course, the material of the adhesive can also be other, as long as it is transparent and has adhesiveness.

Specifically, this step is to coat the transparent optical adhesive 20 on the inner surface of the curved substrate 42 .

Step 502 : Roll the flexible screen 41 and place it inside the curved substrate 42 , and fix one position of the flexible screen 41 on the inner surface corresponding to the first main body portion 421 .

Specifically, the flexible screen 41 is wound into a bundle shape, the width of which is smaller than the distance between the first main body part 421 and the second main body part 422 , and the length is smaller than that of the first main body part 421 . The entire bundle is then placed inside the curved substrate 42 .

Before the flexible screen 41 is placed inside the curved substrate 42 , the flexible screen 41 is divided into two parts according to the area of the first main body part 421 , the second main body part 422 , the first connecting part 423 and the second connecting part 424 of the curved substrate 42 . The corresponding first display part 411 , the second display part 412 and the display connection parts 413 and 414 respectively. Then, mark one of the positions of the second display portion 412 of the flexible screen 41 and the corresponding position of the second main body portion 422 of the curved substrate 12 . After placing the bundled flexible screen 11 inside the curved substrate 12, directly align and fix the two marked positions.

As shown in FIG. 16 , the center position of the second display portion 412 of the flexible screen 41 is marked, and the center position of the second main body portion 422 is marked. After the flexible screen 41 is placed inside the curved substrate 42 , the two positions of the mark are aligned and fixed by the transparent optical glue 20 .

It should be understood that marks may also be made at the center positions of the first display part 411 and the first main body part 421 . Alternatively, one position of the flexible screen 41 is fixed on the corresponding inner surface of the first main body portion 421 . The selection of the position is the same as that of the second main body portion 422 .

Step 503: Put the pressing member 13 into the inner side of the flexible screen 41, and press the flexible screen 41 to the inner surface of the curved substrate 42 by sequentially moving the pressing member 13, so that the flexible screen 41 is connected to the curved substrate through the adhesive 20. 42 is bonded to the inner surface.

Wherein, the pressing member 13 can be a roller. Roll the roller 13 at a fixed position to apply pressure to stick the flexible screen on the inner surface of the curved substrate.

As shown in FIG. 16 , the roller 13 can roll from the central position of the second main body part 422 , that is, the fixed position, toward the direction of the second connecting part 424 , and then returns to the first main body part 421 and the first connecting part 423 after passing through the first main body part 421 and the first connecting part 423 . The center position of the second main body portion 422 .

It should be understood that the drum 13 can also roll in the opposite direction, for example, it can roll at the center position of the second main body part 422, that is, the fixed position starts to roll in the direction of the first connecting part 423, and passes through the first main body part 421 and the second main body part 421. The connecting portion 424 then returns to the center position of the first main body portion 421 .

The radius of the roller 13 is smaller than the bending radius of the first connecting portion 123 , thereby ensuring that the roller 13 can fully fit with the first connecting portion 123 when rolling on the inner surface of the first connecting portion 123 . The probability of foaming of the flexible screen 11 is reduced.
