Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly to a process film, a laminating device, and a laminating method thereof. Background Art

[0002] With the development of display technologies, the types of display devices are increasing, and the types of screen bodies are also increasing. During the process of manufacturing a display device, a laminating device is usually used to laminate a cover plate and a screen body in the display device.

[0003] However, due to its own structure, materials, or other designs, the current laminating device can no longer meet the lamination requirements of new types of screen bodies such as three-dimensional (3D) stereoscopic structures. Summary of the Invention

[0004] In view of this, the present application provides a process film, a laminating device, and a laminating method thereof. By arranging a part of the process film in the laminating device to carry the main screen and another part of the process film to carry the secondary screen, the process film in the laminating device is adapted to the screen body having the main screen and the secondary screen, which is beneficial to simultaneously laminating the main screen and the secondary screen with the cover plate, reducing the manufacturing time of the display device, and also beneficial to ensuring the lamination accuracy between the screen body and the cover plate, thereby improving the product yield of the display device.

[0005] The first aspect of the present application provides a laminating device for laminating a screen body and a cover plate. The screen body includes a main screen and a secondary screen surrounding the outside of the main screen. The laminating device includes a process film for carrying the screen body. The process film includes a first section, a second section surrounding the outside of the first section, and a third section surrounding the outside of the second section. The first section is configured to carry the main screen. At least one through hole is provided on the second section. The third section is configured to carry the secondary screen.

[0006] In the above solution, by arranging the first section to carry the main screen and the third section to carry the secondary screen, the main screen and the secondary screen can be laminated on the process film together, which is beneficial to simultaneously laminating the main screen and the secondary screen with the cover plate, reducing the manufacturing time of the display device. In addition, by providing at least one through hole on the second section, the second section is prevented from wrinkling after being bent, which is beneficial to profiling the second section into a structure adapted to the bent part in the three-dimensional stereoscopic structure presented by the screen body, making the lamination accuracy between the screen body and the process film higher, and further beneficial to ensuring the lamination accuracy between the screen body and the cover plate, thereby improving the product yield of the display device.

[0007] In a specific embodiment of the first aspect of the present application, the second section includes a plurality of first support bars, and through holes are spaced between two adjacent first support bars. Further, one end of the first support bar is connected to the first section, and the other end of the first support bar is connected to the third section. In this way, at least part of the first support bar can be located in the bending area, and then the first support bar can be used for profiling fixation to achieve the bending of the second section, avoiding wrinkles after the second section is bent.

[0008] In a specific embodiment of the first aspect of the present application, the second section further includes at least one second support bar. The second support bar intersects with the first support bar. In this way, the cross-connection between the second support bar and the first support bar can be used to make the structure of the first support bar more stable.

[0009] In a specific embodiment of the first aspect of the present application, the process film further includes a fourth section surrounding the outside of the third section. In this way, during the process of grasping or transporting the process film, the fourth section can be grasped or clamped, avoiding contamination or damage to other sections of the process film except the fourth section.

[0010] In a specific embodiment of the first aspect of the present application, the clamping member is configured to clamp the fourth section. In this way, the fourth section can be clamped by the clamping member, and the process film can be tightened by the clamping member, so that the process film and the screen body attached to the process film are in a tension state, avoiding phenomena such as wrinkles.

[0011] In a specific embodiment of the first aspect of the present application, the laminating device further includes a support member configured to carry the process film. The support member has a first surface, a second surface surrounding the outside of the first surface, and a third surface surrounding the outside of the second surface. The first section is attached to the first surface, the second section is attached to the second surface, and the third section is attached to the third surface. In this way, during the process of laminating the screen body and the cover plate, the support member can be used to push the process film and the screen body attached to the process film to move towards the cover plate, and press the screen body onto the cover plate to achieve the lamination of the screen body and the cover plate.

[0012] In a specific embodiment of the first aspect of the present application, the material of the support member is an elastic material. Further, the elastic material includes silicone. In this way, during the laminating process, under the action of the laminating pressure, the support member can elastically deform to match the surface of the cover plate facing the screen body, making the lamination of the screen body and the cover plate closer, which is beneficial to avoiding problems such as edge bubbles after the lamination of the screen body and the cover plate.

[0013] In a specific embodiment of the first aspect of the present application, an obtuse angle is formed between the first surface and the third surface. Further, the first surface is circular and the third surface is annular. In this way, when the process film after lamination is further laminated with the screen body on the support member, the process film can adaptively change according to the structure of the support member, and the second section in the process film can change from a flat state to a bent state, so that the structure presented by the main screen and the sub-screen is adapted to the structure of the support member. The process film after lamination and the screen body can be three-dimensionally laminated through the support member, which is beneficial to the closer lamination between the screen body and the cover plate and higher lamination accuracy.

[0014] The second aspect of the present application provides a process film for laminating a screen body. The screen body includes a main screen and a sub-screen surrounding the outside of the main screen. The process film includes a first section, a second section surrounding the outside of the first section, and a third section surrounding the outside of the second section. The first section is configured to carry the main screen in the screen body. At least one through hole is provided on the second section. The third section is configured to carry the sub-screen in the screen body.

[0015] The third aspect of the present application provides a lamination method for the lamination device in any specific embodiment of the first aspect of the present application. The lamination method includes: providing a screen body and a cover plate; placing the screen body on the surface of the process film of the lamination device facing the cover plate; using the process film to carry the screen body and move it towards the cover plate to laminate the screen body and the cover plate. The screen body includes a main screen and a sub-screen surrounding the outside of the main screen. The first section of the process film is configured to carry the main screen. The third section of the process film is configured to carry the sub-screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] Display technology has been widely applied in display devices such as mobile phones, tablet computers, e-book readers, players, digital cameras, laptop computers, in-vehicle computers, desktop computers, set-top boxes, smart televisions, wearable devices, etc. As the types of display devices are increasing, the types of screen bodies in display devices are also increasing. For example, the screen body (refer to Figure 1 the screen body 10) of some display devices only includes one display screen (such as a flat display screen or a curved display screen, etc.), and the screen body of some display devices includes two display screens (refer to Figure 2 and Figure 3 the screen body 20, and this screen body 20 includes a main screen 21 and a secondary screen 22) or even more display screens.

[0030] In the process of manufacturing a display device, a bonding device is usually used to bond a cover plate and a screen body in the display device. The bonding device usually includes a process film (usually in a cuboid structure). During the process of bonding the screen body and the cover plate, the process film carries the screen body and moves it towards the cover plate to bond the screen body and the cover plate. However, the current bonding device is only applicable to a display device that includes only one display screen and is not applicable to a display device with multiple display screens. If the display device with multiple display screens is a small-sized electronic product such as a smart watch, the structure of this type of display device is relatively complex, the space occupied by multiple display screens is small, and multiple display screens present a three-dimensional (3D) structure. Assuming that the process film of the existing bonding device is directly used to carry this type of display device, problems such as poor bonding accuracy or high product defect rate will occur due to the mismatch between the process film of the existing bonding device and the structure of this type of display device.

[0031] To solve at least one of the above problems, at least one embodiment of the present application provides a process film, a bonding device and a bonding method thereof. By setting the process film to include a first section, a second section and a third section, and setting the first section to carry the main screen and the third section to carry the secondary screen, the main screen and the secondary screen in the screen body can be bonded to the process film together, which is beneficial to bonding the main screen and the secondary screen to the cover plate at the same time and reduces the manufacturing time of the display device. In addition, by providing at least one through hole on the second section, wrinkles on the second section after bending are avoided, which is beneficial to profiling the second section into a structure adapted to the bent part in the three-dimensional structure presented by the screen body, making the bonding accuracy between the screen body and the process film higher, which is beneficial to ensuring the bonding accuracy between the screen body and the cover plate and also beneficial to improving the product yield of the display device.

[0032] Next, a process film, a bonding device and a bonding method thereof in at least one embodiment of the present application will be illustrated with reference to the accompanying drawings.

[0033] Refer to Figures 2 to 4 , the screen body 20 includes a main screen 21 and a secondary screen 22 surrounding the outside of the main screen 21. It should be noted that the shape of the plane where the main screen 21 is located can be circular as shown in Figures 2 to 4 , or can be regular or irregular shapes such as rectangles or squares. The main screen 21 and the secondary screen 22 may not be connected. The screen body 20 can be a planar structure as shown in Figure 3 before bonding, and can form a three-dimensional structure as shown in Figure 2 or Figure 4 during or after bonding.

[0034] Refer to Figure 4, the display device 100 includes a screen body 20 and a cover plate 30. During the manufacturing process of the display device 100, the bonding device 200 provided in any embodiment of the present application can be used to bond the screen body 20 and the cover plate 30. It should be noted that the structure of the cover plate 30 can be adaptively adjusted according to the structure of the screen body 20, as long as the cover plate 30 can be adapted to the screen body 20. On this basis, the structure of the cover plate 30 is not specifically limited in the embodiments of the present application.

[0035] An uncured ultraviolet curable adhesive can be provided on either the surface of the screen body 20 facing the cover plate 30 or the surface of the cover plate 30 facing the screen body 20. When bonding the screen body 20 and the cover plate 30, the screen body 20 and the cover plate 30 can be first pressed together by the bonding device 200, and then the pressed screen body 20 and cover plate 30 can be subjected to defoaming treatments such as heating and pressurization, and the uncured ultraviolet curable adhesive can be subjected to ultraviolet curing treatment, so as to form the bonded screen body 20 and cover plate 30.

[0036] At least one embodiment of the present application provides a bonding device. Exemplarily, refer to Figures 5 to 8 , Figure 10 and Figure 11 , the bonding device 200 is used to bond the screen body 20 and the cover plate 30. The bonding device 200 includes a process film 210 for carrying the screen body 20. The process film 210 includes a first section 211, a second section 212 surrounding the outside of the first section 211, and a third section 213 surrounding the outside of the second section 212. The first section 211 is configured to carry the main screen 21. At least one through hole K is provided on the second section 212. The third section 213 is configured to carry the sub-screen 22. In this way, by setting the first section 211 to carry the main screen 21, the first section 211 is adapted to the main screen 21, and by setting the third section 213 to carry the sub-screen 22, the third section 213 is adapted to the sub-screen 22, so that the main screen 21 and the sub-screen 22 can be bonded to the process film 210 together, which is beneficial to bonding the main screen 21 and the sub-screen 22 to the cover plate 30 at the same time, reducing the manufacturing time of the display device 100. In addition, by providing at least one through hole K on the second section 212, since the through hole K can provide a shrinking space, the second section 212 is prevented from having wrinkles after being bent, which is beneficial to profiling the second section 212 into a structure adapted to the bent part in the three-dimensional structure presented by the screen body 20 (refer to Figure 2 or Figure 4 ), so that the bonding accuracy between the screen body 20 and the process film 210 is higher, which is beneficial to ensuring the bonding accuracy between the screen body 20 and the cover plate 30 and improving the product yield of the display device 100.

[0037] In some embodiments, when the screen body 20 and the cover plate 30 are attached using the attaching device 200, the process film 210 can be flat in the initial state, that is, the first section 211, the second section 212, and the third section 213 in the process film 210 are located in the same plane. When the process film 210 is in the initial state, the main screen 21 is attached to the first section 211, and the secondary screen 22 is attached to the third section 213. Since the screen body 20 and the process film 210 are attached on the same plane, the screen body 20 and the process film 210 can be attached more closely, and the attaching accuracy is higher.

[0038] The process film 210 can also be referred to as a guiding film or a back film, etc. The process film 210 can be any film layer for carrying the screen body 20. On this basis, the embodiments of the present application do not specifically limit the material and structure of the process film 210. For example, in some embodiments, the process film 210 can be a sticky steel plate. Again, for example, in other embodiments, the process film 210 can include a substrate layer and an adhesive layer, and can further include a release film layer (which can be removed when attaching to the screen body 20). The material of the substrate layer can be such as polyimide, propylene oxide, polyurethane, or polypropylene, etc.

[0039] The first section 211, the second section 212, and the third section 213 in the process film 210 can all be flexible, or only the second section 212 can be flexible. The first section 211 can be at least the part in the process film 210 corresponding to the complete attachment of the main screen 21. The third section 213 can be at least the part in the process film 210 corresponding to the complete attachment of the secondary screen 22. The second section 212 can be the structure connecting the first section 211 and the second section 212. On this basis, the embodiments of the present application do not specifically limit the division of the first section 211, the second section 212, and the third section 213 in the process film 210.

[0040] In some embodiments, the first section 211 can be the part in the process film 210 corresponding to the complete attachment of the main screen 21. In this way, it is beneficial to improve the attachment accuracy between the main screen 21 and the first section 211. The third section 213 can be the part in the process film 210 corresponding to the complete attachment of the secondary screen 22. In this way, it is beneficial to improve the attachment accuracy between the secondary screen 22 and the third section 213.

[0041] In some embodiments, by way of example, with reference to Figure 7 , the second section 212 can be divided into a bending area 1 and a non-bending area 2 located on at least one side of the bending area 1. A part of the through hole K can be located in the bending area 1, and another part of the through hole K can be located in the non-bending area 2. It should be understood that at least one through hole K can also be entirely located in the bending area 1.

[0042] The shape of the fitting surface of the first section 211 can be adapted to the shape of the plane where the main screen 21 is located. The shape of the fitting surface of the third section 213 can be adapted to the shape of the plane where the secondary screen 22 is located. For example, if the shape of the plane where the main screen 21 is located is circular as shown in Figures 2 to 4 , the shape of the fitting surface of the first section 211 can correspondingly be circular (refer to Figures 5 to 8 and Figure 10 ). Also, for example, if the shape of the plane where the main screen 21 is located is rectangular, the shape of the fitting surface of the first section 211 can correspondingly be rectangular (refer to Figure 11 ).

[0043] In the fitting device 200 provided in at least one embodiment of the present application, exemplarily, referring to Figures 6 to 8 and Figure 10 , the process film 210 further includes a fourth section 214 surrounding the outside of the third section 213. In this way, during the process of grasping or transporting the process film 210, the fourth section 214 can be grasped or clamped, preventing other sections of the process film 210 except the fourth section 214 from being contaminated or damaged. In addition, after the screen body 20 is attached to the process film 210, the attached screen body 20 and the process film 210 can be placed at the position facing the cover plate 30 in the fitting device 200 by grasping or clamping the fourth section 214, avoiding directly contacting the screen body 20 when picking up or clamping the attached screen body 20 and the process film 210, which may cause the screen body 20 to be contaminated or damaged.

[0044] In the fitting device 200 provided in at least one embodiment of the present application, exemplarily, referring to Figure 6 , the fitting device 200 further includes a clamping member 220 configured to clamp the fourth section 214. In this way, the fourth section 214 can be clamped by the clamping member 220. On the one hand, it can prevent directly contacting the screen body 20 during clamping, which may cause the screen body 20 to be contaminated or damaged. On the other hand, the clamping member 220 can also be used to tighten the process film 210, making the process film 210 and the screen body 20 attached to the process film 210 in a tensioned state, avoiding phenomena such as wrinkles.

[0045] In some embodiments, referring to Figure 3 , a first flexible circuit board 23 can be connected to the main screen 21, and a second flexible circuit board 24 can be connected to the secondary screen 22. The secondary screen 22 can be provided with a notch at the position where the first flexible circuit board 23 is bent, so as to bend the first flexible circuit board 23 to the back of the main screen 21 at the notch. When the main screen 21 and the secondary screen 22 form a three-dimensional structure, the second flexible circuit board 24 can also be bent to the area on the back of the main screen 21 where the first flexible circuit board 23 is not attached. For example, the second flexible circuit board 24 can be disposed opposite to the first flexible circuit board 23.

[0046] It should be noted that the clamping member 220 can also be referred to as a clip mechanism. The fourth section 214 can also be profiled to the clamping member 220, so that after the clamping member 220 clamps the fourth section 214, the structure of the process film 210 is more stable and does not deform.

[0047] In the laminating device 200 provided in at least one embodiment of the present application, exemplarily, referring to FIGS. 8 and Figure 9 , the laminating device 200 further includes a support member 230 configured to carry the process film 210. The support member 230 has a first surface S1, a second surface S2 surrounding the outside of the first surface S1, and a third surface S3 surrounding the outside of the second surface S2. The first section 211 is laminated on the first surface S1, the second section 212 is laminated on the second surface S2, and the third section 213 is laminated on the third surface S3. In this way, during the lamination process of the screen body 20 and the cover plate 30, the support member 230 can be used to push the process film 210 and the screen body 20 laminated on the process film 210 to move towards the cover plate 30, and press the screen body 20 onto the cover plate 30 to achieve the lamination of the screen body 20 and the cover plate 30. In addition, the support member 230 can also play a role in protecting the process film 210 and the screen body 20.

[0048] It should be noted that the support member 230 can be represented by PAD. The support member 230 can be any component capable of carrying the process film 210. The hardness of the support member 230 can be greater than the hardness of the process film 210, so as to improve the load-bearing effect on the process film 210 and the supporting effect on the screen body 20. It should be noted that the support member 230 may further have a fourth surface surrounding the outside of the third surface S3, and the fourth section 214 can be laminated on the fourth surface.

[0049] In the laminating device 200 provided in at least one embodiment of the present application, the material of the support member 230 is an elastic material. Further, the elastic material includes silicone. In this way, during the lamination process, under the action of the lamination pressure, the support member 230 can elastically deform to match the surface of the cover plate 30 facing the screen body 20, so that the screen body 20 and the cover plate 30 are laminated more tightly, which is beneficial to avoiding problems such as edge bubbles after the screen body 20 and the cover plate 30 are laminated.

[0050] It should be noted that the elastic material includes but is not limited to silicone, and can also be materials such as thermoplastic elastomer.

[0051] In the laminating device 200 provided in at least one embodiment of the present application, an obtuse angle is formed between the first surface S1 and the third surface S3. In this way, the support member 230 is a three-dimensional structure, and the support member 230 can be adapted to the corresponding three-dimensional structure of the screen body 20. Thus, when the laminated process film 210 and the screen body 20 are further laminated on the support member 230, the process film 210 can adaptively change according to the structure of the support member 230. The second section 212 in the process film 210 can change from a flat state to a bent state, so that the structure presented by the main screen 21 and the secondary screen 22 is adapted to the structure of the support member 230. The laminated process film 210 and the screen body 20 can be three-dimensionally laminated through the support member 230, which is beneficial to making the lamination between the screen body 20 and the cover plate 30 closer and the lamination accuracy higher.

[0052] Further, in some embodiments, the first surface S1 is circular and the third surface S3 is annular. In this way, the support member 230 can be a frustum structure, making the support member 230 more suitable for laminating the screen body 20 with a circular main screen 21 and an annular secondary screen 22 and the cover plate 30.

[0053] The number of through holes K provided in the second section 212 can be one (refer to Figure 5 ), or can be multiple (refer to Figures 6 to 8 , Figure 10 and Figure 11 ). At least one through hole K can be provided at any position in the second section 212. For example, at least one through hole K can be provided only on the part of the second section 212 located in the bending area. Another example is that some through holes K can be provided on the part of the second section 212 located in the bending area, and another part of the through holes K can be provided on the part of the second section 212 located in the non-bending area. The shape of the through hole K can be circular, semi-annular or polygonal, etc. Hereinafter, in combination with several specific embodiments, the structural design of the second section 212 in the process film 210 will be exemplified.

[0054] For example, in the laminating device 200 provided in at least one embodiment of the present application, exemplarily, refer to Figures 6 to 8 , and Figure 10 and Figure 11 , the second section 212 includes a plurality of first support bars 212a, and a through hole K is provided between two adjacent first support bars 212a. In this way, the through hole K can be formed by using the interval between two adjacent first support bars 212a, and further, the through hole K is used to provide a contraction space, avoiding the phenomenon of wrinkles appearing when the second section 212 is bent.

[0055] Furthermore, one end of the first support bar 212a is connected to the first section 211, and the other end of the first support bar 212a is connected to the third section 213. In this way, at least part of the first support bar 212a can be located in the bending zone 1, and then the first support bar 212a is used for profiling fixation to achieve the bending of the second section 212, and because the first support bar 212a is a strip structure, there is at least one through hole K between two adjacent first support bars 212a, thereby avoiding wrinkles after the second section 212 is bent.

[0056] It should be noted that one end of the first support bar 212a may be directly connected to the first section 211, or indirectly connected to the first section 211 through an annular portion in the second section 212 close to the first section 211. The other end of the first support bar 212a may be directly connected to the third section 213, or indirectly connected to the first section 211 through an annular portion in the second section 212 close to the third section 213.

[0057] For another example, in the laminating device 200 provided in at least one embodiment of the present application, illustratively, reference Figure 10 The second section 212 further includes at least one second support bar 212b. The second support bar 212b intersects with the first support bar 212a. In this way, the cross connection between the second support bar 212b and the first support bar 212a can be utilized to make the structure of the first support bar 212a more stable.

[0058] At least one embodiment of the present application further provides a process film, and the process film 210 is used for bonding the screen body 20. The screen body 20 includes a main screen 21 and a sub-screen 22 surrounded outside the main screen 21. The process film 210 includes a first section 211, a second section 212 surrounded outside the first section 211, and a third section 213 surrounded outside the second section 212. The first section 211 is configured to carry the main screen 21. The second section 212 is provided with at least one through hole K. The third section is configured to carry the sub-screen 22.

[0059] The process film 210 of the embodiment of the present application can refer to the description of the bonding device 200 in any of the above embodiments. The process film 210 may include all the technical features of the process film 210 in the above bonding device 200, so it can at least achieve all the above technical effects, which will not be repeated here.

[0060] At least one embodiment of the present application further provides a bonding method of the bonding device 200 based on any of the above embodiments. For example, refer to Figure 12 , the bonding method includes the following steps.
