Taking a mobile phone as an example, none of the mobile phones from a keyboard key mobile phone to a touch screen mobile phone to a large-sized mobile phone and the most popular ' full screen ' mobile phone at present considers the user's feeling. Particularly, the most popular 'full screen' mobile phones at present are more and more popular due to good touch and appearance. However, all the existing mobile phones do not realize a real full screen, and how to realize the full screen becomes a problem to be solved urgently.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic front view structure diagram of a curved screen according to an embodiment of the present application, and fig. 2 is a schematic side view structure diagram of the curved screen shown in fig. 1. As shown in fig. 1, the curved panel 10 of the present embodiment includes a flexible panel 11 and a curved substrate 12.

The curved substrate 12 serves as a carrier for the flexible screen 11. The curved substrate 12 may be made of transparent glass or other transparent plastic.

The curved substrate 12 includes a first portion 13 and a second portion 14.

The first part 13 and the second part 14 are adhered through transparent soft glue 15. The transparent soft glue 15 is flexible adhesive glue, and the first part 13 and the second part 14 can rotate relative to the transparent soft glue 15 as a rotating shaft to form an unfolded state or a folded state.

The first portion 13 and the second portion 14 may be bonded by other transparent flexible adhesive, which is not limited herein.

The first portion 13 and the second portion 14 form a first body portion 121, a second body portion 122, and a connecting portion 123 when closed.

The first body portion 121 and the second body portion 122 are disposed opposite and in parallel. The first body portion 121 and the second body portion 122 are both planar structures. The areas of the two are equal and are both larger than the area of the connecting portion 123.

It is understood that the first and

second body portions

121 and 122 may not be parallel as long as they are oppositely disposed. The first body 121 and the second body 122 may have curved structures.

The connecting portion 123 is one and connects the first sides of the first body portion 121 and the second body portion 122 on the same side, and as shown in fig. 1, the connecting portion 123 connects the right sides of the first body portion 121 and the second body portion 122 or the left side shown in fig. 2. The opening 100 is formed on the other side of the first and

second body portions

121 and 122, i.e., the side opposite to the connecting portion 123, as shown on the left side in fig. 1 or on the right side in fig. 2. The opening 100 is opened in the circumferential surface of the curved substrate 12.

The first portion 13 includes a first body portion 121 and a partial connection portion 123, and the second portion 14 includes a second body portion 122 and a partial connection portion 123. That is, the connection part 123 includes two portions, a first sub-connection part 1231 and a second sub-connection part 1232, respectively.

sub-connecting parts

1231 and 1232 may have the same shape. The first sub-connecting portion 1231 is integrally formed with the first body portion 121, and the second sub-connecting portion 1232 is integrally formed with the second body portion 122.

The end of the first sub-connecting portion 1231 away from the first main body 121 is connected to the end of the second sub-connecting portion 1232 away from the second main body 124 through the transparent soft glue 15.

The connecting portion 123 is bent at 180 degrees and is bent at an arc shape, that is, the first sub-connecting portion 1231 and the second sub-connecting portion 1232 are bent at 90 degrees, respectively, so that the curved substrate 12 has a horizontal U-shaped structure. The curved structure can improve the touch feeling of the user when holding the hand. In other embodiments, the connecting portion 123 may also be bent at a right angle or in other angle configurations.

A method of forming the curved panel of the above-described structure will be described below.

Referring to fig. 9, fig. 9 is a schematic flow chart illustrating a method for manufacturing a curved panel according to an embodiment of the present application. The curved screen comprises a transparent curved substrate and a flexible screen, and the curved substrate comprises at least two parts. The manufacturing method of the present embodiment includes the steps of:

step 101: at least two parts are adhered by transparent soft glue.

The method comprises the step of adhering the closest end of at least two parts by transparent soft glue. The transparent soft glue is flexible adhesive glue, and at least two parts can rotate relative to the transparent soft glue as a rotating shaft to form an unfolded state or a folded state.

Step 102: at least two parts are relatively unfolded by taking the transparent soft glue as an axis.

Specifically, at least one part of the soft rubber is relatively static, and at least another part of the soft rubber is unfolded relative to at least one part of the soft rubber by taking the transparent soft rubber as an axis.

Step 103: a flexible screen is attached to the inner surface of the at least two portions.

A transparent optical glue may be applied to the inner surface of the at least two parts spread out prior to this step.

The step may specifically be attaching the flexible screen to the inner surfaces of the at least two portions by transparent optical glue.

Step 104: the at least two parts which are unfolded are folded to form a first main body part and a second main body part which are oppositely arranged and a connecting part which is used for connecting the first main body part and the second main body part.

The first main body part and the second main body part are arranged in parallel, the first main body part and the second main body part are planar, the connecting part is bent for 180 degrees, and the area of the first main body part and the area of the second main body part are both larger than the area of the connecting part.

Therefore, the flexible screen also forms a first display part, a second display part and a display connecting part which respectively correspond to the first main body part, the second main body part and the connecting part along with the folding of the curved substrate.

The method of manufacturing the curved panel will be described in detail below by taking the curved panel 10 of the previous embodiment as an example, and it will be understood that the curved panels 20, 30 and 40 having similar shapes can be referred to the manufacturing method.

Referring to fig. 10 and 11, fig. 10 is a schematic flow chart illustrating a manufacturing method of another curved screen according to an embodiment of the present application. FIG. 11 is a process diagram corresponding to the method of FIG. 10. The curved panel of this embodiment still comprises a flexible panel 11 and a curved substrate 12. The curved substrate 12 includes a first portion 13 and a second portion 14.

The manufacturing method of the present embodiment includes the steps of:

step 201: the first part 13 and the second part 14 of the curved substrate 12 are adhered by the transparent soft glue 15.

Other transparent flexible adhesives may also be used, without limitation.

Step 202: the first part 13 and the second part 14 are relatively unfolded by taking the transparent soft glue 15 as an axis, and the inner surfaces of the relatively unfolded first part 13 and the second part 14 are coated with the transparent optical glue 20.

In this step, the first portion 13 and the second portion 14 may be spread out such that portions of the first portion 13 and the second portion 14 form the same plane. As shown in fig. 11, in conjunction with the foregoing, the first and

second portions

13 and 14 may be unfolded such that the first and

second body portions

121 and 122 are in the same plane.

The transparent optical adhesive 20 is, for example, an oca (optical Clear adhesive) optical adhesive, which includes both resistive and capacitive types. Of course, the material of the transparent optical adhesive 20 may be other, as long as it is transparent and adhesive.

Step 203: the flexible screen 11 is applied to the inner surfaces of the first and

second portions

13, 14.

The flexible screen 11 is applied to the inner surfaces of the first and

second portions

13, 14, in particular by means of a transparent optical glue 20.

This step may be specifically to gradually attach the flexible screen 11 to the inner surfaces of the first portion 13 and the second portion 14 of the curved substrate 12 from one end of the curved substrate 12. For example, in step 203 of fig. 11, the flexible screen 11 is gradually attached to the inner surfaces of the first portion 13 and the second portion 14 of the curved substrate 12 in the order from left to right. The generation of bubbles can be reduced.

Further, after the attaching operation is completed, the flexible screen 11 may be further pressed by a pressing member such as a roller.

Step 204: the first and

second parts

13 and 14 are folded to form two first and second

main body parts

121 and 122 disposed opposite to each other and a connecting part 123 connecting the first and second

main body parts

121 and 122.

It will be appreciated that the direction of deployment and the direction of retraction are exactly opposite.

The flexible panel 11 is also formed following the curved substrate 12 into the first display section 111, the second display section 112, and the display connection section 113 corresponding to the first body section 121, the second body section 122, and the connection section 123.

Because the flexible screen 11 is attached under the condition that the curved substrate 12 is unfolded, on one hand, the attachment of the flexible screen 11 is facilitated, and on the other hand, the generation of bubbles in the flexible screen 11 can be reduced.

The above-described manufacturing method is applicable to both of the curved-surface-corresponding substrates.

The following will describe a method of manufacturing a flexible panel in which a curved substrate is three-part. The details are described specifically with reference to the curved screen 50 described above as an example. It should be understood that the manufacturing method is also applicable when the curved substrate is 4 parts or more.

Referring to fig. 12 and 13, fig. 12 is a schematic flow chart illustrating a manufacturing method of another curved panel according to an embodiment of the present application, and fig. 13 is a schematic process diagram corresponding to the manufacturing method illustrated in fig. 12.

Step 301: the first part 53, the second part 54 and the third part 56 of the curved substrate 52 are bonded by the transparent soft glue 55.

Other transparent flexible adhesives may also be used, without limitation.

Step 302: the first part 53, the second part 54 and the third part 56 are relatively unfolded with the transparent soft glue 55 as an axis.

In this step, the first portion 53, the second portion 54, and the third portion 56 may be unfolded such that the first portion 53 and the second portion 54 form the same plane. As shown in fig. 13, in conjunction with the foregoing, the first portion 53, the second portion 54, and the third portion 56 may be unfolded such that the first body portion 521 and the second body portion 522 are in the same plane.

Step 303: the flexible screen 51 is attached to the inner surfaces of the first, second and

third portions

53, 54, 56.

Wherein the inner surfaces of the unfolded first and

second portions

53 and 54 are further coated with transparent optical glue 20 before the flexible screen 51 is attached.

The transparent optical adhesive 20 is, for example, an oca (optical Clear adhesive) optical adhesive, which includes both resistive and capacitive types. Of course, the adhesive can be made of other materials as long as the material is transparent.

The flexible screen 11 is attached to the inner surfaces of the first and

second portions

53, 54, in particular by means of transparent optical glue 20. The specific attaching manner is as described above, and is not described herein.

Step 304: the first, second and

third parts

53, 54 and 56 are folded to form two first and second

main body portions

521 and 522 oppositely arranged and a connecting portion 523 connecting the first and second

main body portions

521 and 522. The first portion 53, the second portion 54, and the third portion 56 may correspond to the connection portions 523 of the first main body portion 521 and the second main body portion 522, respectively.

The flexible panel 51 is also formed into the first display portion 511, the second display portion 512, and the display connection portion 513 corresponding to the first and second

main body portions

521 and 522 and the connection portion 523.

Since the flexible screen 51 is attached under the condition that the curved substrate 52 is unfolded, on one hand, the attachment of the flexible screen 51 is facilitated, and on the other hand, the generation of bubbles in the flexible screen 51 can be reduced.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
