Currently, hyperboloid or quadric display panels are operated to increase the screen ratio. Following this is the hyperbolic bonding technique and the quadric bonding technique.
As shown in fig. 1, the curved display panel 1 includes a curved cover plate 11 and a flexible screen 12, and the flexible screen 12 needs to be attached to the curved cover plate 11 during the forming process of the curved display panel 1. The curved cover plate 11 generally includes a planar portion 101 and a curved portion 102 disposed on at least one side of the planar portion 101.
At present, the bonding method of the flexible screen 12 and the curved cover plate 11 mainly uses a silica gel pad, and the bonding purpose of the flexible screen 12 and the curved cover plate 11 is achieved by utilizing the deformation of the silica gel pad. In the attaching process of the curved cover plate 11 and the flexible screen 12, the shape of the curved surface part 102 causes insufficient deformation of the silica gel, so that bubbles are easily generated in the attaching process between the curved surface part 102 and the flexible screen 12, and the yield of the curved surface display panel 1 is seriously affected.
The present invention has been made to solve the above-mentioned problems. In order to better understand the present invention, the following describes the curved display panel fixture, the bonding apparatus and the bonding method according to the embodiments of the present invention in detail with reference to fig. 2 to 13.
Referring to fig. 2 and fig. 3 together, fig. 2 is a side view of a curved display panel fixture 10 according to an embodiment of the invention. Fig. 3 is a top view of a curved display panel fixture 10 according to an embodiment of the first aspect of the present invention. The curved display panel jig 10 is used for attaching a flexible screen 12 and a curved cover plate 11.
According to the curved display panel jig 10 provided in the embodiment of the invention, the curved display panel jig 10 includes: a first support region 10A and a second support region 10B distributed around (at least partially around) the first support region 10A; the main body support 100 includes a first support portion 110 located in the first support region 10A, the first support portion 110 having a first bearing surface 111; the sliding support 200 is located in the second supporting area 10B and is movably disposed relative to the first supporting portion 110 in a direction perpendicular to the first bearing surface 111, and the sliding support 200 has a first shaped bearing surface 210, where the first shaped bearing surface 210 and the first bearing surface 111 are used for bearing the flexible screen 12.
The direction perpendicular to the first bearing surface 111 is, for example, the Z direction in fig. 2.
In the curved display panel jig 10 according to the embodiment of the first aspect of the present invention, the curved display panel jig 10 has a first supporting area 10A and a second supporting area 10B distributed around the first supporting area 10A. In the curved display panel 1, the planar portion 101 of the curved cover plate 11 corresponds to the first support region 10A, and the curved portion 102 of the curved cover plate 11 corresponds to the second support region 10B.
The planar portion 101 of the curved cover plate 11 and the first supporting area 10A correspond to each other and mean: the curved display panel jig 10 is located on the first bearing surface 111 of the first supporting area 10A for bearing the flexible screen 12 and attaching to the planar portion 101. The curved surface portion 102 of the curved surface cover plate 11 and the second supporting area 10B correspond to each other and mean: the curved display panel fixture 10 is located on the first shaped bearing surface 210 of the second supporting area 10B, and is used for bearing the flexible screen 12 and partially or completely adhering to the curved portion 102. The curved display panel fixture 10 of the embodiment of the present invention includes a main body support 100 and a sliding support 200, where the main body support 100 carries the flexible screen 12 in the first support area 10A through the first carrying surface 111, and the sliding support 200 carries the flexible screen 12 in the second support area 10B through the first special-shaped carrying surface 210 in the second support area 10B. The first shaped bearing surface 210 is configured to bear the flexible screen 12 and at least part of the curved surface 102 are mutually attached, and the sliding support 200 is movably disposed in a direction perpendicular to the first bearing surface 111, so that the support of the first shaped bearing surface 210 on the flexible screen 12 can be adjusted by moving the sliding support 200. It should be noted that, the first shaped bearing surface 210 is configured to bear the flexible screen 12 and at least part of the curved surface 102, and in some alternative embodiments, the first shaped bearing surface 210 is configured to bear the flexible screen 12 and part of the curved surface 102, and in other alternative embodiments, the first shaped bearing surface 210 is configured to bear the flexible screen 12 and all of the curved surface 102.
In the process of attaching the curved cover plate 11 and the flexible screen 12 to each other, there is generally an attaching bubble between the curved portion 102 of the curved cover plate 11 and the flexible screen 12 due to insufficient attaching force. When the curved display panel jig 10 provided by the embodiment of the invention is used for attaching the flexible screen 12 and the curved cover plate 11, the main body supporting piece 100 and the sliding supporting piece 200 can be used for supporting the flexible screen 12 together so that the flexible screen 12 and the curved cover plate 11 are attached to each other. The sliding support 200 is then moved further so that the flexible screen 12 on the first contoured load-bearing surface 210 continues to conform to at least a portion of the curved surface 102. That is, after the flexible screen 12 corresponding to the first supporting area 10A is attached to the curved cover plate 11, the sliding supporting member 200 can be used to continuously perform fine adjustment, so as to ensure that a sufficient attaching force exists between the flexible screen 12 corresponding to the second supporting area 10B and the curved surface portion 102, and improve poor attachment between the curved surface portion 102 and the flexible screen 12.
The curved cover plate 11 may be arranged in various ways, and the curved cover plate 11 may have a four-curved or two-curved shape. With continued reference to fig. 1, fig. 1 is a schematic structural view of a hyperbolic cover plate 11. The curved cover plate 11 includes a planar portion 101 and curved portions 102 provided on both sides of the planar portion 101. Poor fit between the curved surface portion 102 and the flexible screen 12 is likely to occur due to the limitation of the shape of the curved surface portion 102 itself.
In some alternative embodiments, the display panel fixture 10 may be used to carry the flexible screen 12 to be attached to the hyperbolic cover plate 11.
With continued reference to fig. 3, the curved display panel fixture 10 shown in fig. 3 is used for bearing the flexible screen 12 and attaching to the hyperbolic curved cover plate 11.
The curved display panel jig 10 in the embodiment of the invention is used for bearing the flexible screen 12 and attaching the curved cover plate 11 shown in fig. 1. The curved display panel fixture 10 includes two sliding supporting members 200, and the two sliding supporting members 200 are respectively disposed on two sides of the first supporting portion 110. The first bearing surface 111 of the first supporting portion 110 is used for bearing the flexible screen 12 and attaching to the planar portion 101, and the first profiled bearing surface 210 of the sliding supporting member 200 is used for bearing the flexible screen 12 and attaching to all the curved portions 102. The sliding support 200 is movably disposed relative to the first support portion 110, and the adhesion between the flexible screen 12 and the curved surface portion 102 can be fine-tuned by the sliding support 200, so as to improve the poor adhesion between the flexible screen 12 and the curved surface portion 102.
In some alternative embodiments, the display panel fixture 10 may be used to carry the flexible screen 12 for attaching to the quadric curved cover plate 11. Referring to fig. 4 and 5 together, fig. 4 is a schematic structural view of a four-curved cover plate 11. Fig. 5 is a schematic structural diagram of a curved display panel fixture 10 according to another embodiment of the first aspect of the present invention.
According to fig. 4, the curved cover plate 11 has a four-curved shape. The four-curved surface cover plate 11 includes a planar portion 101 and a curved surface portion 102, and the curved surface portion 102 includes four shaped portions 103 distributed on the peripheral side of the planar portion 101 and corner portions 104 connecting adjacent two shaped portions 103. The four shaped portions 103 include two first shaped portions 103a disposed opposite in the X direction (first direction) and two second shaped portions 103b disposed opposite in the Y direction (second direction). The first shaped portion 103a and the second shaped portion 103b adjacent in the circumferential direction of the planar portion 101 are connected to each other by a corner portion 104.
The curved display panel jig 10 shown in fig. 5 is used for carrying a flexible screen 12 and attaching to a curved cover plate 11. The sliding support 200 of the curved display panel fixture 10 is used for bearing the flexible screen 11 and the profiled portion 103 and the corner portion 104 to be mutually attached, that is, the first profiled bearing surface 210 is used for bearing the flexible screen 12 and all the curved portions 102 to be mutually attached.
The first supporting portion 110 is located in the first supporting area 10A, and the size of the first supporting portion 110 is adapted to the first supporting area 10A. The sliding support 200 is located in the second support zone 10B, the sliding support 200 being sized to fit the second support zone 10B. The sliding support 200 is used for bearing the flexible screen 11 against the profiled portion 103 and the corner portion 104.
With continued reference to fig. 5, in some alternative embodiments, the sliding support 200 may be integrally formed in a ring-shaped configuration. The slide support 200 is formed integrally in a ring shape and surrounds the outer peripheral side of the main body support 100, and is provided corresponding to the four shaped portions 103 and the corner portions 104. It should be noted that, the corresponding arrangement here refers to: the first shaped bearing surface 210 of the sliding support 200 is used for bearing the flexible screen 12 and the four shaped portions 103 and the corner portions 104 to be mutually attached.
In the use process of the curved display panel jig 10, after the flexible screen 12 supported by the main body support 100 and the sliding support 200 are attached to the curved cover 11, each sliding support 200 can be continuously moved, so that the flexible screen 12 located on the sliding support 200 is attached to each of the shaped portions 103 and each of the corner portions 104, and poor attachment between the flexible screen 12 and each of the shaped portions 103 and each of the corner portions 104 is improved.
Referring to fig. 6, in some alternative embodiments, the sliding support 200 may be provided separately. Fig. 6 is a schematic structural diagram of a curved display panel fixture 10 according to another embodiment of the first aspect of the present invention.
According to the curved display panel jig 10 provided by the embodiment of the invention, the annular sliding support 200 is separately arranged, and the annular sliding support 200 includes the strip-shaped sliding support 240 corresponding to the shaped portion 103 and the corner sliding support 250 corresponding to the corner portion 104. The bar-shaped sliding support 240 provided on the sliding support 200 corresponding to the shaped portion 103 means that: the strip-shaped sliding support 240 is used for supporting the flexible screen 12 and the profiled portion 103 to be mutually attached. The corner slide support 250 provided on the slide support 200 corresponding to the corner 104 means: corner slide supports 250 are used to support flexible screen 12 against corner 104.
As mentioned above, in addition to the embodiment of the sliding support 200 and the second support area 10B with the dimensions adapted as shown in fig. 5 and 6, in other alternative embodiments, the sliding support 200 may be smaller than the dimensions of the second support area 10B, and the sliding support 200 may be used to carry the flexible screen 11 and the corner 104 to fit each other, i.e. the first profiled carrying surface 210 is used to carry the flexible screen 12 and the curved surface 102 to fit each other.
Referring to fig. 7 and fig. 8 together, fig. 7 is a schematic structural diagram of a curved display panel fixture 10 according to another embodiment of the invention. Fig. 8 is an exploded view of fig. 7.
According to the curved display panel fixture 10 provided in the embodiment of the present invention, the main body support 100 further includes: the second supporting portion 120 is located on at least one side of the first supporting portion 110, and the second supporting portion 120 has a second special-shaped carrying surface 121, where the second special-shaped carrying surface 121, the first special-shaped carrying surface 210, and the first carrying surface 111 are used for carrying the flexible screen 12.
Fig. 7 and 8 show the boundary between the first supporting portion 110 and the second supporting portion 120 by a dotted line, and the dotted line constitutes a structural limitation of the curved display panel jig 10 according to the embodiment of the present invention.
It will be appreciated that the second supporting portion 120 and the shaped portion 103 are correspondingly disposed, that is, the second shaped bearing surface 121 of the second supporting portion 120 is used to support the flexible screen 12 and the shaped portion 103 to be mutually attached. The first profiled bearing surface 210 of the sliding support 200 at this point may be used to bear the flexible screen 11 against the corner 104. The arrangement can improve poor fitting of the fitting bubbles generated between the upper corner 104 of the curved cover plate 11 and the flexible screen 12 through the sliding support 200, and meanwhile, the second support 120 does not need to move relative to the first support 110, so that the structure of the curved display panel jig 10 can be simplified.
It should be noted that, the second supporting portion 120 is different from the strip-shaped sliding supporting member 240 in that: the second supporting portion 120 is a part of the main body supporting member 100, and the second supporting portion 120 does not move relative to the first supporting portion 110 in a direction perpendicular to the first bearing surface 111. Alternatively, the second supporting portion 120 and the first supporting portion 110 are integrally formed, so that the structure of the curved display panel fixture 10 can be simplified.
In some alternative embodiments, when the curvature of the shaped portion 103 is smaller, the degree of bending of the shaped portion 103 is smaller, and the fitting air bubbles are less likely to be generated between the shaped portion 103 and the flexible screen 12. However, since the corner portion 104 is a multi-curved surface body, and since the first shaped portion 103a and the second shaped portion 104a are different in length, at least two curved surfaces having different curvatures exist on the corner portion 104, a bonding bubble is easily generated between the corner portion 104 and the flexible screen 12.
When the curved display panel jig 10 according to the embodiment of the present invention is used to attach the curved cover plate 11 and the flexible screen 12, the flexible screen 12 may be first supported by the first supporting portion 110, the second supporting portion 120, and the sliding supporting member 200 together so that the shaped portion 103 and the planar portion 102 of the curved cover plate 11 are attached to each other. And then the sliding support 200 is further moved, so that the flexible screen 12 positioned on the first special-shaped bearing surface 210 is further mutually attached to the corner 104, and poor attachment between the corner 104 and the flexible screen 12 is improved. In the embodiment of the invention, the second supporting portion 120 for bearing the flexible screen 12 and attaching to the shaped portion 103 does not need to move relative to the first supporting portion 110, and can also meet the attaching requirement of the curved cover plate 11 and the flexible 12.
Optionally, the number of the second supporting parts 120 is one or more than two. For example, the number of the second supporting parts 120 is one, and the sliding supporting parts 200 are strip-shaped sliding supporting parts 240, and the number of the second supporting parts 120 is three, and the three strip-shaped sliding supporting parts 240 are respectively arranged on the other sides of the first supporting parts 110. Alternatively, the sliding support 200 has a C-shaped semi-ring shape, and the sliding support 200 and the second support 120 are enclosed on the outer peripheral side of the first support 110.
In other embodiments, the number of the second supporting portions 120 is more than two, the more than two second supporting portions 120 are disposed around the first supporting portion 110 and are formed by extending along different directions, the yielding gap 130 is formed between two adjacent second supporting portions 120 on the peripheral side of the first supporting portion 110, and the sliding supporting member 200 is located in the yielding gap 130.
Note that, the sliding support 200 and the corner 104 where the lamination bubble is easily generated are disposed correspondingly, that is, the sliding support 200 is used to support the flexible screen 12 and the corner 104 to be laminated to each other. After the flexible screen 12 supported by the main body support 100 and the sliding support 200 is attached to the curved cover plate 11, the sliding support 200 can be continuously moved, so that the flexible screen 12 located on the sliding support 200 can be attached to the corner 104, and poor attachment between the flexible screen 12 and the corner 104 is improved.
When the number of the second supporting portions 120 is more than two, for example, please continue to refer to fig. 7 and 8, the number of the second supporting portions 120 is four, and the number of the sliding supporting members 200 is four. The second supporting portion 120 includes two first sub-supporting portions 122 disposed opposite to each other in the X direction and two second sub-supporting portions 123 disposed opposite to each other in the Y direction, the X direction and the Y direction intersecting; a yielding gap 130 is formed between the adjacent first sub-supporting portion 122 and second sub-supporting portion 123, and each yielding gap 130 is respectively provided with a sliding supporting piece 200.
In these alternative embodiments, the second support 120 includes two first sub-supports 122 and two second sub-supports 123. In the use process of the curved display panel jig 10, the two first sub-supporting portions 122 may be respectively disposed corresponding to the two first shaped portions 103a, and the two second sub-supporting portions 123 may be respectively disposed corresponding to the two second shaped portions 103b, that is, the two first sub-supporting portions 122 are used for supporting the flexible screen 12 and respectively attaching to each other with the two first shaped portions 103a, and the two second sub-supporting portions 123 are used for supporting the flexible screen 12 and attaching to each other with the two second shaped portions 103b.
