In the related art, the buffer assembly is pushed by the lifting mechanism to enable the flexible display screen to be attached to the cover plate. Wherein, the apron includes intermediate portion, and the kink that links to each other with the edge of intermediate portion. In the laminating process, the lifting mechanism applies acting force pointing to the middle part of the cover plate to the buffer assembly, and the flexible display screen is laminated with the bent part of the cover plate through the deformation of the buffer assembly.
Due to the force application mode, the part of the flexible display screen corresponding to the middle part of the cover plate bears large acting force, and the part of the flexible display screen corresponding to the bent part of the cover plate bears small acting force. Therefore, the stress of the flexible display screen is uneven, so that the flexible display screen corresponding to the joint of the middle part of the cover plate and the bent part bears larger shearing force, the flexible display screen is broken, and the yield of the curved screen is reduced.
Based on the above problem, the embodiment of the present disclosure provides a display screen attaching process. Fig. 1 is a schematic flow diagram illustrating a display screen attachment process according to an exemplary embodiment.
As shown in fig. 1, the display screen attaching process includes:
and S101, arranging an adhesive on one surface of the cover plate, which is used for being connected with the flexible display screen, and arranging a buffer assembly on one side of the flexible display screen, which deviates from the cover plate.
FIG. 2 is a schematic diagram illustrating a state of the process according to an exemplary embodiment. As shown in FIG. 2, the cushioning assembly 100, the flexible display 200, and the cover 300 are distributed along a direction Z1. The cover plate 300 includes a middle portion 310 and a bent portion 320. An adhesive layer 400 is disposed on a side of the cover plate 300 facing the flexible display 200, and the adhesive layer 400 covers the middle portion 310 and the bent portion 320 of the cover plate 300.
And S102, applying acting force pointing to the middle part of the cover plate to the buffer assembly to enable the flexible display screen to be in contact with the middle part. In this way, the flexible display screen is attached to the middle part of the cover plate.
Step S103, applying an acting force pointing to the bending part of the cover plate to the buffer assembly until the flexible display screen is attached to the bending part. In this way, the flexible display screen is better attached to the bending part of the cover plate.
Since the acting force directed to the bending part of the cover plate is applied to the buffer assembly in step S103, the distribution of the acting force of the buffer assembly on the flexible display screen is more uniform. Furthermore, the problem that the stress of the flexible display screen is uneven is solved, and the flexible display screen is prevented from being broken due to overlarge shearing force.
In the embodiment of the present disclosure, the implementation manners of step S102 and step S103 are different based on different buffer components, and the following description is made with reference to specific embodiments.
Fig. 3 and 4 are schematic diagrams illustrating states of different stages in a display screen attaching process according to an exemplary embodiment.
In one embodiment, as shown in figures 3 and 4, cushioning assembly 100 includes a flexible bladder 110 having a removably blocked opening 111, with a fluid 120 filled into flexible bladder 110 through opening 111. Also, the flexible bladder 110 has a good deformation capability (e.g., a silicone bladder), and the flexible bladder 110 is volumetrically expanded by filling the flexible bladder 110 with the fluid 120.
In such a case, as shown in fig. 3, step S102 specifically includes: a force directed toward the middle portion 310 of the cover 300 is applied to the buffer assembly 100 by a pushing mechanism to bring the flexible display 200 into contact with the middle portion 310 of the cover 300.
At this time, the opening 111 of the flexible bag 110 is in a closed state. Optionally, the flexible display screen is driven by an electric pushing device, a hydraulic pushing device, a pneumatic pushing device, or the like to push the buffering assembly 100.
As shown in fig. 4, step S103 specifically includes: the fluid 120 is filled into the flexible bladder 110, causing the flexible bladder 110 to expand toward the bent portion 320 of the cover plate 300.
At this time, the opening 111 of the flexible bag 110 is opened, and the fluid 120 is filled into the flexible bag 110 through the opening 111. Further, the flexible bag 110 expands to push the flexible display 200 to fit the bending portion 320 of the cover 300.
In this manner, the attaching surface of the flexible pouch 110 to the flexible display 200 is increased by the inflated flexible pouch 110, thereby achieving uniform force application of the flexible display 200 by the flexible pouch 110 to attach the flexible display 200 to the cover 300. Therefore, the stress uniformity of the flexible display screen 200 is improved, and the flexible display screen 200 is prevented from being broken due to the fact that the local part bears large shearing force.
As an example, the fluid 120 filled in the flexible bladder 110 includes: particulates and lubricants. The resistance to relative movement of the particles is reduced by the lubricant, reducing the resistance to deformation of flexible bladder 110.
The particles in the fluid 120 may be selected as spheres with a diameter less than or equal to 6mm (e.g., 5mm, 4mm, 3mm, 2mm), which further reduces the relative motion resistance of the particles and improves the fluidity of the fluid 120 to prevent the flexible bladder 110 from adhering to the flexible display 200. In addition, the diameter of the particles 120 is less than or equal to 6mm, so that the flexible display screen 200 can be attached to the bending part 320 of 160 ° or less by the buffer assembly 100, which meets most product requirements. The hardness of the particles is 50 to 65 degrees rockwell (e.g., 55 degrees, 60 degrees) to optimize the durability of the cushion assembly 100.
As another example, fluid 120 filled within flexible bladder 110 is a gas. That is, the volumetric expansion of flexible bladder 110 is achieved by inflation.
After step S103, the opening 111 of the flexible bag 110 is sealed, and the pressure of the buffer assembly 100 on the flexible display screen 200 is maintained for a set period of time, so as to ensure that the flexible display screen 200 is stably attached to the cover plate 300. Wherein, the set applying section can be selected to be 4s, 5s, 6s, 7s, 8s, etc., and the pressure applied by the buffer assembly 100 to the flexible display screen 200 can be selected to be 0.3Mpa, 0.4Mpa, 0.5 Mpa.
It should be noted that, in this embodiment, step S102 is performed first, and after the flexible display screen is contacted with the middle portion of the cover plate, step S103 is performed. And filling fluid in the step S103 to enable the flexible bag to expand towards the middle part of the cover plate, namely applying acting force towards the cover plate on the flexible display screen by the flexible bag, so that the attaching effect of the flexible display screen and the cover plate is guaranteed.
Fig. 5 and 6 are schematic diagrams illustrating states of different stages in a display screen attaching process according to an exemplary embodiment.
In one embodiment, as shown in fig. 5 and 6, the cushioning assembly 100 includes a base 130, and a protrusion 140 disposed on an edge region of the base 130. The protrusion 140 is used to abut against the portion of the flexible display 200 that fits the bending portion 320. And, a vibration assembly 500 is attached to a side of the base 130 facing away from the protrusion 140.
In such a case, as shown in fig. 5, step S102 specifically includes: a force directed toward the middle portion 320 of the cover plate 300 is applied to the buffer assembly 100 by the pushing mechanism to bring the flexible display 200 into contact with the middle portion 320 (the buffer assembly 100 is not yet in contact with the middle portion 310 of the cover plate 300 as shown in fig. 5).
Optionally, the flexible display screen is driven by an electric pushing device, a hydraulic pushing device, a pneumatic pushing device, or the like to push the buffering assembly 100.
As shown in fig. 6, step S103 specifically includes: the vibration assembly 500 applies a force to the damping assembly 100 directed to the bent portion 320, so that the protrusion 140 vibrates in a direction directed to the bent portion 320. For example, in FIG. 6, the protrusions 140 vibrate in directions x1 and x 2.
In this manner, the protrusions 140 are vibrated by the vibration assembly 500 such that each protrusion 140 contacts a different area of the flexible display 200. In other words, as the protrusion 140 vibrates, the position of the force applied by the buffering assembly 100 to the flexible display screen 200 is continuously changed. In this way, the stress position of the flexible display screen 200 is constantly changed, so that stress concentration is avoided, and the stress uniformity of the flexible display screen 200 is ensured.
It should be noted that, in the implementation of the present disclosure, during the process of applying the force directed to the bent portion 320 to the shock absorbing assembly 100, the pushing mechanism is maintained to apply the force directed to the middle portion 310 to the shock absorbing assembly 100. That is, step S102 is synchronously executed in the execution of step S103. In the process that the pushing mechanism pushes the buffering assembly 100, the vibration assembly 500 drives the protrusion 140 to vibrate, so that the stress at the joint of the flexible display screen 200 and the bending part 320 is uniform. Furthermore, the shearing force borne by the joint of the flexible display screen 200 and the bending part 320 is weakened, and the fracture risk is reduced.
Optionally, the hardness of the protrusion 140 is 10-40 degrees in Rockwell hardness, such as 15 degrees, 20 degrees, 25 degrees, 30 degrees, and the like. In this way, the protrusions 140 are soft and easily deformed, and damage to the structure of the flexible display screen 200 during vibration is avoided.
Optionally, the vibration assembly 500 is an ultrasonic vibrator for outputting ultrasonic waves to drive the protrusion 140 to vibrate. In this way, the ultrasonic wave drives the protrusion 140 to generate a small displacement at a high frequency, so that the protrusion 140 can be rapidly replaced at the connection position with the flexible display screen 200.
Optionally, the middle portion of the base 130 is also provided with a protrusion 140 for abutting against the portion of the flexible display screen 200 attached to the middle portion 310 of the cover plate 300, so as to optimize the deformation performance of the buffer assembly 100, better play a role in buffering, and ensure the structural safety of the flexible display screen 200.
According to the display screen attaching process provided by the embodiment of the disclosure, the buffer assembly drives the flexible display screen to attach to the middle part by applying the acting force pointing to the middle part of the cover plate to the buffer assembly. Through the acting force to the bending part pointed by the buffering component, the buffering component drives the flexible display screen to be attached to the bending part. The whole process ensures that the stress of the flexible display screen is uniform, avoids the flexible display screen from being fractured due to stress concentration, and improves the laminating yield of the curved screen.
In a second aspect, an embodiment of the present disclosure provides a buffer assembly, where the buffer assembly is applied to the display screen attaching process provided in the first aspect. The cushion assembly includes a flexible bladder having an opening, and a fluid filled in the flexible bladder.

When the buffering assembly is used, the stress uniformity of the flexible display screen is guaranteed, the flexible display screen is prevented from being broken due to stress concentration, and the yield of the laminating process is improved.
In a third aspect, an embodiment of the present disclosure provides a buffer assembly, where the buffer assembly is applied to the display screen attaching process provided in the first aspect. The cushion assembly includes a base, and a protrusion provided at an edge portion of the base. Wherein, the arch is used for pasting with flexible display screen mutually, and the base member deviates from protruding one side and is used for connecting the vibration subassembly.
