Based on the defects of high production cost and difficulty in volume production of electronic equipment with a surrounding screen assembly in the related art, the embodiment of the disclosure provides electronic equipment, a display screen assembly and a display screen assembly production process.

In a first aspect, an embodiment of the present disclosure provides an electronic device. Fig. 1 is a schematic structural diagram of an electronic device shown according to an exemplary embodiment. As shown in fig. 1, the electronic device includes a display screen assembly 300, and a center frame assembly 400.

The display screen assembly 300 has an interior cavity 310. Specifically, the display screen assembly 300 includes a cover plate 100 and a flexible display screen 200. The cover plate 100 forms a cavity, and the flexible display screen 200 is disposed in the cavity formed by the cover plate 100 and attached to the inner wall of the cover plate 100. At this time, the rear surface of the flexible display 200 forms an inner wall of the inner cavity 310.

Fig. 2-1 and 2-2 are schematic structural views of a cover plate according to various exemplary embodiments. As shown in fig. 2-1 and 2-2, a cover plate 100 provided by the embodiment of the present disclosure encloses a cavity 110. The chamber 110 has a first opening 111 and a second opening 112 disposed opposite to each other. Alternatively, the cover plate 100 is made of a transparent material, such as glass, transparent resin, and the like.

With respect to the specific shape of the cap plate 100, the radial section of the cap plate 100 includes a first side 121, a second side 122, a third side 123, and a fourth side 124, which are sequentially connected. Alternatively, referring to fig. 2-1, the first side 121 and the third side 123 are distributed in parallel, and preferably, the first side 121 and the third side 123 are straight sides. The second and

fourth sides

122 and 124 are arc-shaped sides that protrude toward the outside of the chamber 110. At this time, the inner wall of the chamber 110 includes a flat portion 113 and a curved portion 114, the flat portion 113 is a plane on which the first side 121 and the third side 123 are located, and the curved portion 114 is a plane on which the second side 122 and the fourth side 124 are located. Alternatively, referring to fig. 2-2, the second and

fourth sides

122 and 124 are arcuate sides at opposite ends and the middle portion is a flat side connected to the arcuate sides.

In an electronic device to which the display screen assembly is applied, the surfaces of the first edge 121 and the third edge 123 of the cover plate 100 form the front or the back of the electronic device, and the surfaces of the second edge 122 and the fourth edge 124 of the cover plate 100 form the curved side surfaces of the electronic device. In this way, the grip feel of the electronic device is improved by bending the side surfaces. In particular, compared with the solution shown in fig. 2-2, the case shown in fig. 2-1 can further increase the curvature of the second side 122 and the fourth side 124, so that the display screen can be attached to the cover plate 100 in the subsequent step, and the difficulty of the assembly process of the display device is reduced.

With continued reference to fig. 1, the center frame assembly 400 includes a circuit board, and a functional module mounted on the circuit board. Wherein, the specific types of the functional modules are not limited, including but not limited to: camera module, microphone module, earphone module, vibration module, heat dissipation module, battery module. The middle frame assembly 400 is inserted into the inner cavity 310 of the display panel assembly 300, and the circuit board is electrically connected to the flexible display panel 200 in the display panel assembly 300.

The display screen assembly 300 of the electronic device provided by the embodiment of the present disclosure is a surround screen. And this display screen subassembly 300 forms through laminating flexible display screen 200 at the cavity 110 inboard that the apron 100 becomes, and the processing degree of difficulty of display screen subassembly 300 has been reduced to such structure. By inserting the middle frame assembly 400 into the inner cavity 310 of the display screen assembly 300, the difficulty of assembling the whole electronic device is reduced, and the integration level of the whole electronic device is improved. To sum up, the electronic equipment that this disclosed embodiment provided produces the degree of difficulty and is lower, easily realizes the volume production.

A first barrier 510 and a second barrier 520 are disposed at opposite ends of the circuit board, respectively. The first baffle 510 and the second baffle are positioned on opposite sides of the internal cavity 310 and are positioned to be external to the internal cavity 310. The middle frame assembly 400 is limited in the inner cavity 310 through the first baffle 510 and the second baffle 520, so that the electronic equipment is integrally sealed.

Optionally, at least one of the first baffle 510 and the second baffle 520 may be removably attached to the center frame assembly 400 to facilitate servicing or cleaning of the center frame assembly 400.

As an example, the first baffle 510 is fixedly coupled (e.g., by being integrally formed or coupled by a connector) to a circuit board in the center frame assembly 400. The edge of the first baffle 510 extends beyond the opening edge of the inner cavity 310, so that the first baffle 510 is limited outside the inner cavity 310.

Optionally, the second baffle 520 is removably attached to the center frame assembly 400. For example, a threaded hole is provided on the end surface of the circuit board, and the second baffle 520 is connected to the circuit board by the engagement of a screw with the threaded hole. In addition, a decoration is disposed outside the second barrier 520 to cover traces of screws, thereby beautifying the appearance of the electronic device.

In this manner, when the middle frame assembly 400 of the electronic device needs to be repaired, the middle frame assembly 400 can be separated from the inner cavity 310 by detaching the second baffle 520 from the middle frame assembly 400.

Fig. 3 is a schematic structural diagram of an electronic device shown according to another exemplary embodiment. Referring to fig. 3, a buffer layer 600 is disposed at an end of the first barrier 510 adjacent to the display panel assembly 400 and at an end of the second barrier 520 adjacent to the display panel assembly 300. The buffer layer 600 is used to buffer the first and

second barrier plates

510 and 520 from the display screen assembly 300 and the middle frame assembly 400. Especially, when the electronic device bears external force, the buffer layer 600 is used for relieving the impact of the external force on the display screen assembly 300, the middle frame assembly 400 and the baffle plate, so that the anti-falling function is achieved.

Optionally, the buffer layer 600 includes a first buffer part 610 and a second buffer part 620 connected. Wherein an edge of the first buffer portion 610 is disposed beyond an edge of the second buffer portion 620. And, the edge of the first buffer portion 610 exceeds the outer surface of the display screen assembly 300 by at least 0.2mm. Accordingly, the first buffer portion 610 is located outside the inner cavity 310. And, the second buffer 620 is inserted into the inner cavity 310.

The first buffer portion 610 serves as a buffer between the barrier (the first barrier 510 and the second barrier 520) and the display panel assembly 300, and the second buffer portion 620 serves as a buffer between the barrier (the first barrier 510 and the second barrier 520) and the middle frame assembly 400.

The cushioning layer 600 is made of an elastic material (e.g., rubber or resin). Alternatively, the elasticity of the second buffer portion 620 is greater than that of the first buffer portion 610. At this time, the first re-buffering is realized by the first buffering part 610, and the second re-buffering is realized by the second buffering part 620, and the buffering strength of the second re-buffering is greater than that of the first re-buffering. The second buffer part 620 is made of a material with larger elasticity, so that the second buffer part 620 has better deformation capacity and further presents stronger buffer force. Since the second buffer 620 is located in the inner cavity 310 and may be in contact with the middle frame assembly 400 and the flexible display screen, this is done in such a way that the second buffer 620 substantially protects the internal components of the electronic device. Alternatively, the baffle and the buffer layer 600 are manufactured by multiple injection molding, so that the first baffle 510 and the buffer layer 600, and the second baffle 520 and the buffer layer 600 are of an integral structure.

To sum up, the display screen assembly 300 in the electronic device provided by the embodiment of the present disclosure is a surrounding screen structure, and the structure of the electronic device is optimized to reduce the assembly process of the whole electronic device and improve the mass production performance of the electronic device.

In a second aspect, the disclosed embodiments provide a display screen assembly. FIG. 4 is a schematic diagram illustrating a configuration of a display screen assembly according to an exemplary embodiment. As shown in fig. 4, the display screen assembly 300 includes: a cover plate 100 and a flexible display 200.

The cover plate 100 forms a cavity 110, and the flexible display screen 200 is located in the cavity 110 of the cover plate 100 and attached to an inner wall of the cavity 110. The display panel assembly 300 further includes a flat cable 230 electrically connected to the flexible display panel 200, and an insulating fixing member 240 covering the flat cable 230. An insulating fixing member 240 (e.g., a release paper) covers a portion of the flat cable 230 so that the flat cable 230 and the flexible display 200 are relatively fixed. The insulating fixing member 240 is used to prevent the flat cable 230 from colliding with other components (such as a battery and a circuit board in an electronic device) to cause structural damage, and the structural stability of the display screen component 300 is guaranteed.

The display screen assembly 300 provided by the embodiment of the disclosure is used for forming a surround screen in an electronic device. In the embodiment of the present disclosure, the structure of the display screen assembly 300 is optimized, so that the difficulty of the production process of the display screen assembly 300 is reduced, and the mass production performance of the display screen assembly 300 is improved.

In a third aspect, the disclosed embodiments provide a display panel assembly production process for producing the display panel assembly provided in the second aspect. FIG. 5 is a flow chart illustrating a display screen assembly production process according to one exemplary embodiment. As shown in fig. 5, the production process of the display screen assembly specifically includes:

And S102, curling the flexible display screen into a reel shape, inserting the reel-shaped flexible display screen into the cavity from the opening of the cover plate cavity, and adjusting the relative positions of the flexible display screen and the edges of the two ends of the cavity.

And S103, unfolding the flexible display screen, and attaching the unfolded flexible display screen to the inner wall of the cover plate cavity.

In the embodiment of the present disclosure, the scroll form of the flexible display screen in step S102 includes two implementations of the first form and the second form. Fig. 6-1 is a schematic structural diagram illustrating a first configuration according to an exemplary embodiment, and fig. 6-2 is a schematic structural diagram illustrating a second configuration according to an exemplary embodiment.

As shown in fig. 6-1, the flexible display 200 includes a first end 210 and a second end 220 that are oppositely disposed. The flexible display 200 assumes the first configuration by crimping the first end 210 of the flexible display 200 toward the first end 220.

As shown in fig. 6-2, the flexible display 200 includes a first end 210 and a second end 220 that are oppositely disposed, and an intermediate portion 250 that is located between the first end 210 and the second end 220. The flexible display 200 assumes the second configuration by crimping the first end 210 and the second end 220 of the flexible display 200 toward the middle portion 250 of the flexible display 200.

In such a case, FIGS. 6-3 are partial flow diagrams of a display screen assembly production process shown according to one exemplary embodiment. As shown in fig. 6-3, step S102 specifically includes:

and S1021, determining the diameter of the radial section of the flexible display screen in the first form.

And S1022, when the diameter is smaller than the set threshold, curling the flexible display screen into a first form, and when the diameter is larger than or equal to the set threshold, curling the flexible display screen into a second form.

Optionally, the set threshold is determined according to the size of the inner cavity of the cover plate. As shown in fig. 2-1, the threshold is determined according to the distance between the first edge 121 and the third edge 123 of the cover plate 100, for example, the threshold is set to 70%, 75%, 80%, 85%, etc. of the distance between the first edge 121 and the third edge 123.

By adopting the mode, when the diameter of the radial section of the flexible display screen in the first state is smaller than the set threshold value, the flexible display screen cannot scratch the inner wall of the cavity in the subsequent assembly process of inserting the flexible display screen into the inner cavity. At the moment, the first form is adopted as the scroll form, so that the flexible display screen structure is prevented from being damaged in the subsequent process.

When the diameter of the radial section of the flexible display screen in the first state is greater than or equal to the set threshold, the flexible display screen may scratch the inner wall of the cavity in a subsequent assembly process in which the flexible display screen is inserted into the inner cavity. Therefore, the second form is adopted as the reel form to reduce the radial section size of the flexible display screen and avoid damaging the flexible display screen structure in the subsequent process.

Therefore, the specific implementation mode of the reel form is determined based on the set threshold value, the stable structure of the flexible display screen in the whole process is guaranteed, and the yield of the display screen assembly is improved.

In the disclosed embodiment, an alternative is provided for step S103. FIG. 7 is a partial flow diagram of a display screen assembly manufacturing process according to another exemplary embodiment. As shown in fig. 7, step S103 includes:

In step S1031, the preset region of the flexible display screen is attached to the flat portion, so as to achieve the initial fixation between the flexible display screen and the cover plate. In the subsequent process steps, the displacement of the flexible display screen and the cover plate is avoided, and the production efficiency and the assembly accuracy are improved.

Based on the difference of the reel forms of the flexible display screen, different selection modes are adopted in the preset area of the flexible display screen.

Referring to fig. 6-1, when the radial cross-sectional diameter of the flexible display screen in the first configuration is smaller than the set threshold, the preset area X is located on the end portion (the first end 210 or the second end 220) of the flexible display screen.

Optionally, a roller is used for rolling the flexible display screen, so that the flexible display screen is pressed and attached to the inner wall of the cavity while being unfolded.

Referring to fig. 6-2, when the radial cross-sectional diameter of the flexible display screen in the first configuration is smaller than the set threshold, the second configuration is adopted as the scroll configuration, and the preset region X is located on the middle portion 250 of the flexible display screen.

In such a case, step S1031 includes: and stretching the first roller into the cavity, and rolling the flexible display screen to attach the preset area on the leveling part. Wherein, the width of the preset area is more than or equal to 2 times of the diameter of the first roller.
