Description

Technical Field

[0001] The present disclosure relates to the technical field of display panels, and in particular to a display panel bonding device. Background Art

[0002] With the continuous development of electronic devices, people's requirements for display panels are becoming increasingly higher, and full-screen display devices are becoming increasingly popular. Currently, the demand for full-screen electronic devices is mainly met through flexible screens. Flexible screen bonding mainly uses elastic push blocks to press the flexible screen onto the inner side of the glass cover.

[0003] However, during the bonding process, since the thrust applied by the pushing device to the elastic pushing block is generally kept uniform, and the elastic pushing block is subjected to different forces in the flat area and the bent area, the elastic pushing block undergoes different deformations in the flat area and the bent area, which in turn causes bubbles to appear between the glass cover and the flexible screen. In particular, the occurrence of bubbles between the glass cover and the flexible screen corresponding to the bent area of the elastic pushing block is more frequent, thereby affecting the display effect of the display panel. Summary of the Invention

[0004] An embodiment of the present disclosure provides a display panel bonding device to solve the problem of bubbles being easily generated between a flexible display panel and a glass cover in the related art.

[0005] In order to solve the above technical problems, the present disclosure is implemented as follows:

The laminating device includes a pushing module, an auxiliary pushing module, and an elastic pushing block.

[0007] The glass cover is configured to cover the first surface of the flexible display module, the flexible display module includes a central area and an edge area, wherein the edge area is located on the periphery of the central area and is arc-shaped, and the first surface is the surface from which light emerges from the flexible display module;

[0008] The top of the elastic pushing block is covered by the flexible display module when attached to the display panel, the pushing module is clamped on the bottom of the elastic pushing block, and the second surface of the flexible display module is attached to the top of the elastic pushing block. The top of the elastic pushing block includes a curved surface area and a bonding area, the curved surface area is opposite to the edge area, the bonding area is opposite to the center area, and both the curved surface area and the edge area are convex toward the glass cover plate;

[0009] The auxiliary pushing module is arranged on one side of the pushing module and contacts the bottom of the elastic pushing block. When there is no gap between the central area and the glass cover, the auxiliary pushing module pushes the elastic pushing block to make the curved surface area and the edge area fit together until there is no gap between the edge area and the glass cover, wherein the second surface of the flexible display module is opposite to the first surface.

[0010] Optionally, the distance between the edge of the arc surface area and the plane where the fitting area is located is 0.25 mm.

[0011] Optionally, the elastic pushing block is a silicone elastic pushing block.

[0012] Optionally, a card connector is further provided at the bottom of the elastic pushing block, and the card connector is card-connected to the top of the pushing module.

[0013] Optionally, a first fixing member, a second fixing member, a first fixing pressure strip and a second fixing pressure strip are provided on the top of the pushing module;

[0014] The clamping joint includes a first strip-shaped clamping buckle and a second strip-shaped clamping buckle, wherein the table surface of the first strip-shaped clamping buckle and the buckling table surface of the second strip-shaped clamping buckle are opposite to each other;

[0015] The first fixing bead is pressed onto the first end of the first strip buckle and the first end of the second strip buckle, and the second fixing bead is pressed onto the second end of the first strip buckle and the second end of the second strip buckle, wherein the first end of the first strip buckle and the first end of the second strip buckle face the same direction, and the second end of the second strip buckle and the second end of the second strip buckle face the same direction;

[0016] The first fixing member and the second fixing member are detachably connected to the top of the pushing module, the first fixing pressure strip is fixedly connected to the first fixing member, and the second fixing pressure strip is fixedly connected to the second fixing member.

[0017] Optionally, the curvature of the curved surface area is equal to the curvature of the edge area.

[0018] Optionally, the auxiliary pushing module includes a driving member and a first telescopic rod and a second telescopic rod;

[0019] The first end of the first telescopic rod and the first end of the second telescopic rod are both connected to the driving member, the second end of the first telescopic rod is fixed at a first position at the bottom of the elastic pushing block, and the second end of the second telescopic rod is fixed at a second position at the bottom of the elastic pushing block. There is a first angle between the telescopic direction of the first telescopic rod and the plane where the bottom of the elastic pushing block is located, and there is a second angle between the telescopic direction of the first telescopic rod and the plane where the bottom of the elastic pushing block is located, wherein the first position and the second position are both areas opposite to the bottom of the elastic pushing block and the arc surface area, and the first angle and the second angle are both acute angles.

[0020] Optionally, the auxiliary pushing module further includes a first lifting pad and a second lifting pad;

[0022] Optionally, the first angle is equal to the second angle.

[0023] Optionally, the side surface of the elastic pushing block has a limiting protrusion;

[0024] The limiting protrusion protrudes from the side surface of the elastic pushing block, and the end of the edge area is clamped between the limiting protrusion and the glass cover plate without a gap between the edge area and the glass cover plate, wherein the side surface is a surface perpendicular to the first surface.

[0025] In an embodiment of the present invention, since the top of the elastic push block is covered by the flexible display module when the display panel is attached, the push module is clamped to the bottom of the elastic push block, and the second surface of the flexible display module is attached to the top of the elastic push block. This ensures that during the attachment of the display panel to the glass cover, bubbles are driven from the center area of the flexible display module to the edge area. Furthermore, since the top of the elastic push block includes a curved surface area and an attachment area, the curved surface area and the edge area are opposite, and the attachment area and the center area are opposite, the attachment effect between the attachment area of the elastic push block and the edge area of the flexible display module is improved. Furthermore, since the auxiliary push module is disposed on one side of the push module and contacts the bottom of the elastic push block, when there is no gap between the center area and the glass cover, the push module pushes the elastic push block to attach the curved surface area and the edge area until there is no gap between the edge area and the glass cover. Therefore, the external force on the curved surface area of the elastic push block is greater than that on the attachment area of the elastic push block, thereby better evacuating bubbles between the flexible display module and the glass cover, thereby improving the display effect of the display panel.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0040] The display panel bonding device according to the embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1 A schematic diagram showing the structure of the display panel bonding device provided by an embodiment of the present disclosure before complete bonding, Figure 2 A schematic diagram showing the structure of the display panel bonding device provided by an embodiment of the present disclosure after complete bonding, Figure 3 A schematic diagram showing the force between the display panel bonding device and the display panel provided by the embodiment of the present disclosure. Figure 1 、 Figure 2 and Figure 3As shown, the bonding device of the display panel is used to bond the display panel, the display panel includes a glass cover plate 10 and a flexible display module 20, and the bonding device includes a pushing module 30 and an elastic pushing block 50; the glass cover plate 10 is configured to cover the first surface of the flexible display module 20, the flexible display module 20 includes a central area 201 and an edge area 202, wherein the edge area 202 is located on the peripheral side of the central area 201, the edge area 202 is arc-shaped, and the first surface is the surface of the flexible display module 20 emitting light; the top of the elastic pushing block 50 is covered by the flexible display module 20 when bonding the display panel, the pushing module 30 is clamped on the bottom of the elastic pushing block 50, and the second surface of the flexible display module 20 and the elastic pushing block 50 are connected. The top of the movable block 50 is fitted, and the top of the elastic pushing block 50 includes a curved surface area 501 and a fitting area 502. The curved surface area 501 is opposite to the edge area 202, and the fitting area 502 is opposite to the center area 201. The curved surface area 501 and the edge area 202 are both convex toward the glass cover 10; the auxiliary pushing module 40 is arranged on one side of the pushing module 30 and contacts the bottom of the elastic pushing block 50. When there is no gap between the center area 201 and the glass cover 10, the pushing module 30 pushes the elastic pushing block 50 to fit the curved surface area 501 and the edge area 202 until there is no gap between the edge area 202 and the glass cover 10, wherein the second surface of the flexible display module 20 is opposite to the first surface.

[0042] The glass cover 10 is the outermost panel that protects the internal structure of the display panel. It is primarily used to protect the internal structure of the display panel and prevent the intrusion of dust, water, etc. In some embodiments, to accommodate the curved display surface of the display panel, the edge of the glass cover 10 is curved, and the specific curvature is determined by the curvature of the flexible display module 20.

[0043] The glass cover plate 10 is typically configured to cover the first surface of the flexible display module 20, that is, the glass cover plate 10 is typically located on the emission surface of the flexible display module 20. The flexible display module 20 includes a central region 201 and an edge region 202. The central region 201 is the area where the flat surface of the flexible display module 20 is located after full lamination, and the edge region 202 is located around the central region 201. The edge region 202 is the area where the curved surface of the flexible display module 20 is located after full lamination.

[0044] It should be noted that during the lamination process of the glass cover plate 10 and the flexible display module 20, bubbles are easily formed in the lamination area 502 of the glass cover plate 10 and the flexible display module 20. These bubbles are difficult to remove from between the glass cover plate 10 and the flexible display module 20 after lamination, resulting in poor lamination of the display panel and affecting the display quality of the display panel. Factors that typically affect the lamination quality between the glass cover plate 10 and the flexible display module 20 include the physical properties of the material of the elastic push block 50, the lamination pressure, and the height difference between the curved surface area 501 and the lamination area 502 of the elastic push block 50.

[0045] Based on this, to ensure that, when the lamination pressure is satisfied, bubbles generated between the glass cover plate 10 and the flexible display module 20 during the lamination process are driven from the central region 201 to the edge region 202, in the embodiment of the present disclosure, the top of the elastic push block 50 is covered by the flexible display module 20 when the display panel is lamination, the push module 30 is snapped onto the bottom of the elastic push block 50, and the second surface of the flexible display module 20 is in contact with the top of the elastic push block 50. This ensures that, during the lamination process between the display panel and the glass cover plate 10, bubbles are driven from the central region 201 of the flexible display module 20 to the edge region 202. Furthermore, because the top of the elastic push block 50 includes a curved surface region 501 and a laminating region 502, with the curved surface region 501 and the edge region 202 facing each other, and the laminating region 502 and the central region 201 facing each other, the laminating effect between the laminating region 502 of the elastic push block 50 and the edge region 202 of the flexible display module 20 is improved.

[0046] It should be noted that the bonding area 502 is the area of the plane on the surface of the top of the elastic push block 5, and the area of the bonding area 502 is equal to the area of the central area 201 of the flexible display module 20. The curved surface area 501 located around the bonding area 502 is a circular arc surface, opposite the edge area 202 of the flexible display module 20. The projected area of the curved surface area 501 on the glass cover plate 10 along a direction perpendicular to the glass cover plate 10 is equal to the projected area of the edge area 202 on the glass cover plate 10 along a direction perpendicular to the glass cover plate 10. In addition, both the edge area 202 and the curved surface area 501 are convex toward the glass cover plate 10 to ensure a good bonding effect between the edge area 202 and the curved surface area 501.

[0047] Optional, such as Figure 3 As shown, the distance h between the plane where the edge region 202 is located and the plane where the central region 201 is located is 0.25 mm.

[0048] Furthermore, the elastic pushing block 50 is a silicone elastic pushing block 50 .

[0049] It should be noted that, based on the elastic modulus of the silicone material of 0.8 kgf / mm² and the bonding pressure of 0.2 MPa, the deformation of the silicone elastic pusher 50 is calculated as x = 0.2 MPa / 0.8 kgf / mm² (Mpa) = 0.25 mm. The above calculation results show that when the silicone edge is 0.25 mm higher than the center height, the bonding area 502 of the flexible display module 20, which is located at the top of the silicone elastic pusher 50 and is relative to the center point of the center area 201, first contacts the glass cover plate 10. As the deformation of the silicone elastic pusher 50 increases to 0.25 mm, the distance h between the plane of the edge area 202 and the plane of the center area 201 is controlled to 0.25 mm, ensuring that the edge area 202 of the flexible display module 20 is completely bonded to the edge area 202 of the glass cover plate 10, thereby further reducing the number of bubbles between the glass cover plate 10 and the flexible display module 20.

[0050] In addition, the curvature of the curved area 501 is equal to that of the edge area 202 , so that the curved area 501 can be completely fitted with the edge area 202 , thereby promoting complete fitting between the glass cover 10 and the edge area 202 of the flexible display module 20 .

[0051] The elastic push block 50 can be clamped on the top of the push module 30 to maintain position stability between the elastic push block 50 and the push module 30. Specifically, a clamping joint is further provided at the bottom of the elastic push block 50, and the clamping joint is clamped on the top of the push module 30.

[0052] It should be noted that the card connector may be an L-shaped card connector, a T-shaped card connector, or a card connector of other shapes, which is not limited in the embodiments of the present disclosure.

[0053] Optional, such as Figure 4 、 Figure 5 and Figure 6As shown, the top of the pushing module 30 is provided with a first fixing member 301, a second fixing member 302, a first fixing pressure strip 303 and a second fixing pressure strip 304; the clamping joint includes a first bar buckle 503 and a second bar buckle 504, and the table surface of the first bar buckle 503 and the table surface of the second bar buckle 504 are opposite; the first fixing pressure strip 303 is pressed on the first end of the first bar buckle 503 and the first end of the second bar buckle 504, and the second fixing pressure strip 304 is pressed on the first bar buckle 503 and the second end of the second bar buckle 504, wherein the first end of the first bar buckle 503 and the first end of the second bar buckle 504 are oriented in the same direction, and the second end of the first bar buckle 503 and the second end of the second bar buckle 504 are oriented in the same direction; the first fixing member 301 and the second fixing member 302 are detachably connected to the top of the pushing module 30, the first fixed pressure strip 303 and the first fixing member 301 are fixedly connected, and the second fixed pressure strip 304 and the second fixing member 302 are fixedly connected.

[0054] It should be noted that the first strip buckle 503 and the second strip buckle 504 are both arranged along the extension direction of the surface on which the bottom of the elastic push block 50 is located, that is, the length of the first strip buckle 503 and the length of the second strip buckle 504 are consistent with the length of the bottom of the elastic push block 50. The first strip buckle 503 and the second strip buckle 504 are both L-shaped buckles, and the engaging surfaces formed by the first strip buckle 503 and the second strip buckle 504 are opposite. That is, the portion of the first strip buckle 503 perpendicular to the bottom of the elastic push block 50 and the portion of the second strip buckle 504 perpendicular to the bottom of the elastic push block 50 are opposite, thereby forming an overlapping surface between the first strip buckle 503 and the second strip buckle 504. In this way, the first fixed pressure strip 303 can be pressed onto the first end of the first bar buckle 503 and the first end of the second bar buckle 504, and the second fixed pressure strip 304 can be pressed onto the second end of the first bar buckle 503 and the second end of the second bar buckle 504, and then detachably connected to the top of the pushing module 30 through the first fixing member 301 and the second fixing member 302. The first fixed pressure strip 303 and the first fixing member 301 are fixedly connected, and the second fixed pressure strip 304 and the second fixing member 302 are fixedly connected, so that the elastic pushing block 50 can be detachably connected to the end of the pushing module 30, thereby facilitating the disassembly and assembly between the elastic pushing block 50 and the pushing module 30 while ensuring the relative position stability between the elastic pushing block 50 and the pushing module 30.

[0055] In addition, it should be noted that during the bonding process, Figures 7 to 10 As shown, the push module 30 applies an external force to the elastic push block 50, wherein the push force is as follows Figures 7 to 10As shown in F in the figure, the flexible display module 20 and the glass cover plate 10 are pressed together. Under normal circumstances, the thrust applied by the pushing module 30 is uniform and constant. However, under the same thrust, the elastic deformation generated when the fitting area 502 and the curved area 501 of the elastic pushing block 50 contact the flexible display module 20 is different. In particular, in the curved area 501, the curved area 501 of the elastic pushing block 50 needs to undergo a greater deformation under the action of the external force to better achieve the fitting of the flexible display module 20 and the glass cover plate 10. The greater the deformation of the curved area 501 in the elastic pushing block 50, the better the bubbles between the flexible display module 20 and the glass cover plate 10 will be discharged. Therefore, different pressures need to be applied to the fitting area 502 and the curved area of the elastic pushing block 50, so that the elastic pushing block 50 undergoes "controllable distributed" deformation.

[0056] Based on this, the display panel bonding device provided by the embodiment of the present disclosure also includes a pushing module 30. When there is no gap between the central area 201 and the glass cover plate 10, the pushing module 30 pushes the elastic pushing block 50 to make there be no gap between the edge area 202 and the glass cover plate 10, wherein the second surface is opposite to the first surface.

[0057] It should be noted that the pushing module 30 can be a rocker slider mechanism, a crank connecting rod mechanism, a sprocket feeding mechanism, or other structures capable of providing linear thrust, and the embodiment of the present invention does not limit this.

[0058] In some embodiments, as Figure 1 and Figure 2 As shown, the auxiliary pushing module 40 includes a driving member and a first telescopic rod 401 and a second telescopic rod 402; the first end of the first telescopic rod 401 and the first end of the second telescopic rod 402 are both connected to the driving member, the second end of the first telescopic rod 401 is fixed at a first position at the bottom of the elastic pushing block 50, and the second end of the second telescopic rod 402 is fixed at a second position at the bottom of the elastic pushing block 50, and there is a first angle between the telescopic direction of the first telescopic rod 401 and the plane where the bottom of the elastic pushing block 50 is located, and there is a second angle between the telescopic direction of the first telescopic rod 401 and the plane where the bottom of the elastic pushing block 50 is located, wherein the first position and the second position are both areas opposite to the bottom of the elastic pushing block 50 and the arc surface area 501, and the first angle and the second angle are both acute angles.

[0059] It should be noted that the driving member may include a first cylinder and a second cylinder, the first cylinder being connected to the first telescopic rod 401, and the second cylinder being connected to the second telescopic rod 402, such that the first cylinder can drive the first telescopic rod 401 to extend and retract, and the second cylinder can drive the second telescopic rod 402 to extend and retract. Since the second end of the first telescopic rod 401 is fixed at a first position at the bottom of the elastic pushing block 50, and the second end of the second telescopic rod 402 is fixed at a second position at the bottom of the elastic pushing block 50, the first position and the second position are both areas where the bottom of the elastic pushing block 50 and the curved surface area 501 are opposite, so when there is no gap between the central area 201 and the glass cover 10, the edge area 202 of the elastic pushing block 50 can be deformed by means of the second telescopic rod 402 and the second telescopic rod 402. Furthermore, since there is a first angle between the telescopic direction of the first telescopic rod 401 and the plane on which the bottom of the elastic pushing block 50 is located, and a second angle between the telescopic direction of the first telescopic rod 401 and the plane on which the bottom of the elastic pushing block 50 is located, and both the first angle and the second angle are acute angles, the component force applied by the first telescopic rod 401 and the second telescopic rod 402 to the elastic pushing block 50 is distributed radially along the curved surface area 501, so that the external force applied to the curved surface area 501 of the elastic pushing block 50 is greater than that applied to the fitting area 502 of the elastic pushing block 50, thereby better discharging bubbles between the flexible display module 20 and the glass cover plate 10.

[0060] In addition, in the embodiment of the present disclosure, the first angle between the telescopic direction of the first telescopic rod 401 and the plane on which the bottom of the elastic pushing block 50 is located can be equal to the second angle between the telescopic direction of the first telescopic rod 401 and the plane on which the bottom of the elastic pushing block 50 is located. Therefore, when the first telescopic rod 401 and the second telescopic rod 402 are driven simultaneously and the driving force they receive is the same, the thrusts received by the first position and the second position of the elastic pushing block 50 can be equal, which is beneficial for maintaining the stability of the elastic pushing block 50 and avoiding the position displacement of the elastic pushing block 50 due to the push of the auxiliary pushing module 40.

[0061] Optionally, the pushing module 30 also includes a first lifting pad 403 and a second lifting pad 404; the first lifting pad 403 and the second lifting pad 404 are fixed at a first position and a second position respectively, the second end of the first telescopic rod 401 is fixedly connected to the first lifting pad 403, and the second end of the second telescopic rod 402 is fixedly connected to the second lifting pad 404.

[0062] It should be noted that the first lifting pad 403 and the second lifting pad 404 can both be silicone pads, so that the first lifting pad 403 can absorb part of the thrust of the first telescopic rod 401, and the second lifting pad 404 can absorb part of the thrust of the second telescopic rod 402, thereby avoiding stress concentration at the first position and second position of the elastic pushing block 50, and avoiding structural damage to the elastic pushing block 50.

[0063] In addition, in some embodiments, the side surface of the elastic pushing block 50 has a limiting protrusion; the limiting protrusion protrudes from the side surface of the elastic pushing block 50, and when there is no gap between the edge area 202 and the glass cover plate 10, the end of the edge area 202 is clamped between the limiting protrusion and the glass cover plate 10, wherein the side surface is a surface perpendicular to the first surface.

[0064] It should be noted that, since there is no gap between the edge area 202 and the glass cover plate 10, the end of the edge area 202 is clamped between the limiting protrusion and the glass cover plate 10. Therefore, after there is no gap between the edge area 202 and the glass cover plate 10, the position of the edge area 202 of the flexible display module 20 is limited by the limiting protrusion, which is beneficial to improving the fitting effect between the edge area 202 of the flexible display panel and the glass cover plate 10.

[0065] As can be seen from the above embodiment, in the embodiment of the present disclosure, since the top of the elastic pushing block 50 is covered by the flexible display module 20 when the display panel is attached, the pushing module 30 is clamped to the bottom of the elastic pushing block 50, and the second surface of the flexible display module 20 is attached to the top of the elastic pushing block 50. In this way, it can be ensured that during the process of attaching the display panel to the glass cover 10, bubbles can be driven from the central area 201 of the flexible display module 20 to the edge area 202. In addition, since the top of the elastic pushing block 50 includes a curved surface area 501 and a bonding area 502, the curved surface area 501 and the edge area 202 are opposite, and the bonding area 502 and the central area 201 are opposite, the bonding effect between the bonding area 502 of the elastic pushing block 50 and the edge area 202 of the flexible display module 20 is improved. Furthermore, since the auxiliary pushing module 40 is arranged on one side of the pushing module 30 and contacts the bottom of the elastic pushing block 50, when there is no gap between the central area 201 and the glass cover plate 10, the pushing module 30 pushes the elastic pushing block 50 to make the curved surface area 501 and the edge area 202 fit together until there is no gap between the edge area 202 and the glass cover plate 10. Therefore, the external force exerted on the curved surface area 501 of the elastic pushing block 50 is greater than that on the fitting area 502 of the elastic pushing block 50, thereby better discharging the bubbles between the flexible display module 20 and the glass cover plate 10, thereby improving the display effect of the display panel.
