[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0046] This disclosure discloses a screen assembly including a screen, a mid-frame, an adhesive resist portion, and a connector. The mid-frame includes a first part and a second part. The first part is disposed on the periphery of the screen, and the second part is opposite to the back of the screen. A first through hole is provided through the second part. The adhesive resist portion is disposed on the second part and is respectively attached to the back of the screen and the second part. The adhesive resist portion extends along the edge of the screen and closes. The connector is respectively attached to the screen and the mid-frame. The connector flows into the first through hole and connects at least the periphery of the screen and the first part. The connector extends along the edge of the screen and closes.

[0047] In the embodiments of this disclosure, by providing a connector between the screen and the mid-frame that closes circumferentially along the screen, effective connection and sealing of the screen and mid-frame can be achieved. No further adhesive application is required between the screen and the mid-frame, effectively reducing the width of the non-display area of ​​the screen assembly. Furthermore, because the entire connector flows in through the first through-hole, it automatically seals the periphery of the screen during the flow process, eliminating the need for a separate process or procedure for applying adhesive to the periphery of the screen. This not only reduces process costs but also saves time.

[0048] A screen assembly refers to a screen and the components used to install and fix the screen. For example, a screen assembly may include a combination of a screen and a mid-frame, as well as components for connecting the screen and the mid-frame.

[0049] Figure 1 This is a structural diagram of a screen assembly according to an exemplary embodiment. Figure 2 This is a cross-sectional view of a screen component according to an exemplary embodiment, such as... Figure 1 , Figure 2 As shown, the screen assembly includes a screen 1, a mid-frame 2, an adhesive resist portion 3, and a connector 4. The mid-frame 2 includes a first part 21 and a second part 22. The first part 21 is disposed on the periphery of the screen 1, and the second part 22 is opposite to the back of the screen 1. The second part 22 is provided with a first through hole 221. The adhesive resist portion 3 is disposed on the second part 22 and is attached to the back of the screen 1 and the second part 22 respectively. The adhesive resist portion 3 extends along the edge of the screen 1 and closes. The connector 4 is attached to the screen 1 and the mid-frame 2 respectively. The connector 4 flows into and at least connects the periphery of the screen 1 and the first part 21 through the first through hole 221. The connector 4 extends along the edge of the screen 1 and closes.

[0050] In the embodiments disclosed herein, the connector 4 flowing into the screen 1 and the middle frame 2 through the first through hole 221 achieves a circumferential seal between the screen 1 and the middle frame 2. No further adhesive application or other operations are required between the screen 1 and the middle frame 2, thus eliminating the need for a corresponding spatial structure. This effectively reduces the width of the non-display area, achieving a larger screen-to-body ratio and improving the user experience. Furthermore, the connector 4 flowing into the screen 1 through the first through hole 221 directly forms a circumferential wrap around the screen 1, eliminating the need for additional processes to seal or apply adhesive to the periphery of the screen 1, simplifying the process and saving time.

[0051] Figure 3 This is a cross-sectional view of a screen component according to an exemplary embodiment, such as... Figure 3 As shown, the screen 1 includes at least a cover plate 11, a metal layer 13 and a display panel 12 that are stacked on top of each other. The display panel 12 is located between the cover plate 11 and the metal layer 13. The metal layer 13 is disposed opposite to the second part 22. The connector 4 connects the metal layer 13 and the second part 22.

[0052] In this disclosure, the metal layer 13 of the screen 1 is connected to the second part 22 of the middle frame 2 by the connector 4, which can effectively improve the connection strength and make the screen 1 and the middle frame 2 more firmly fixed.

[0053] The screen 1 may also include other layers besides the cover plate 11, the metal layer 13 and the display panel 12, and the connector 4 only needs to be connected to the bottom layer.

[0054] The metal layer 13 can be made of various materials, such as copper or iron, and can be formed in the form of copper foil or stainless steel sheets. It can provide functions for the screen 1, including but not limited to support and protection, electromagnetic shielding, and conductivity.

[0055] In some embodiments, the adhesive resist portion 3 is interference-fitted with the screen 1 and the second portion 22.

[0056] In the embodiments of this disclosure, the interference fit between the adhesive barrier 3, the screen 1 and the second part 22 enhances the sealing between the screen 1, the adhesive barrier 3 and the second part 22, preventing the connector 4 from leaking out of the gap between the screen 1, the adhesive barrier 3 and the second part 22 when it flows in through the first through hole 221.

[0057] In some embodiments, the adhesive-resistant portion 3 is integrally formed and is bonded to the second portion 22.

[0058] In the embodiments disclosed herein, the adhesive-resistant part 3 is bonded to the second part 22, which can fix the position of the adhesive-resistant part 3 on the second part 22 and prevent the adhesive-resistant part 3 from moving relative to the second part 22, causing the connector 4 to move along with it, thereby resulting in the screen 1 and the middle frame 2 not being properly sealed.

[0059] Figure 4 This is a schematic diagram illustrating the structure of a resistive adhesive portion according to an exemplary embodiment, such as... Figure 4 As shown, the adhesive barrier 3 includes several segments 31 connected in sequence. The segments 31 are respectively bonded to the second part 22, and two adjacent segments 31 are connected end to end to form a circumferentially closed adhesive barrier 3.

[0060] In the embodiments of this disclosure, the adhesive resist portion 3 is configured as several segments 31 connected end to end. The specifications and shape of the adhesive resist portion 3 can be adjusted at any time according to different screen components, thereby greatly improving the versatility of the adhesive resist portion 3 composed of several segments 31.

[0061] Figure 5 This is a schematic diagram of the structure of a resistive portion from another perspective, according to an exemplary embodiment, such as... Figure 5 As shown, the ends of the segments 31 are provided with overlapping portions 311, and the overlapping portions 311 of the two segments 31 connected end to end are arranged to overlap in the thickness direction of the screen 1.

[0062] In the embodiments of this disclosure, by overlapping the connecting parts of the segments 31, the pressure at the connecting parts of the segments 31 can be increased, thereby improving the sealing performance of the connecting parts of the segments 31.

[0063] Figure 6 This is a schematic diagram of the structure of a resistive portion from another perspective, according to an exemplary embodiment, such as... Figure 6 As shown, the overlapping portion 311 of segment 31 is provided with a stepped structure, and the stepped structures of adjacent segments 31 cooperate and overlap each other.

[0064] In the embodiments of this disclosure, the overlapping portion 311 of each segment 31 is set as a stepped structure that overlaps and cooperates with each other, which can avoid the situation where the thickness of the overlapping portion 311 of the segment 31 is too large after overlapping and connecting, thereby causing the screen 1 to be lifted from the middle frame 2.

[0065] In some embodiments, the adhesive-resistant part 3 can be a flexible part or a rigid part, and those skilled in the art can choose according to their needs.

[0066] The adhesive barrier 3 may include one or more of the following: silicone parts, foam parts, rubber parts, and flexible plastic parts.

[0067] In some embodiments, such as Figure 1 As shown, the middle frame 2 is rectangular, and the first through hole 221 is set on the long side of the rectangle. The connector 4 is formed by injecting colloid through the first through hole 221.

[0068] The rectangular frame 2 has four straight sides and corners connecting the four straight sides. The colloid flows more smoothly along the straight sides and flows more slowly at the corners.

[0069] In the embodiments of this disclosure, the first through hole 221 for injecting the colloid is set on the long side of the rectangular frame 2. After the colloid flows into the frame 2, it can flow a longer distance along the long side of the frame 2 before passing through the corner of the rectangular frame 2. By setting the first through hole 221 on the long side of the rectangular frame 2, the distance that the colloid can flow smoothly is significantly greater than if the first through hole 221 were set on the short side or corner of the rectangular frame 2, thereby increasing the speed of injecting the colloid and, to a certain extent, avoiding the formation of cavities inside the injected colloid.

[0070] Figure 7 This is a schematic diagram illustrating the structure of a screen assembly according to an exemplary embodiment, such as... Figure 7 As shown, the second part 22 has a second through hole 222. The second through hole 222 and the first through hole 221 are spaced apart along the extension direction of the first part 21. The second through hole 222 is used to overflow the colloid.

[0071] Because the colloid has a certain viscosity, when the colloid is poured through the first through hole 221, the colloid may flow slowly, causing the colloid to accumulate near the first through hole 221 and block the flow channel of the colloid, resulting in airtight blockage when the colloid flows forward.

[0072] In the embodiments of this disclosure, a second through hole 222 is provided in the second part 22 to relieve pressure on the flow channel of the colloid in the second part 22, making the flow of the colloid in the second part 22 smoother. At the same time, when the flow channel of the colloid in the second part 22 is full, the colloid will overflow from the second through hole 222 to determine whether the colloid filling is complete.

[0073] Figure 8 This is a schematic diagram illustrating the structure of a screen assembly according to an exemplary embodiment, such as... Figure 8 As shown, the screen assembly includes a plurality of first through holes 221 and a plurality of second through holes 222. The plurality of first through holes 221 and the plurality of second through holes 222 are arranged alternately along the extension direction of the first part 21, and the distance between the first through hole 221 and two adjacent second through holes 222 is the same.

[0074] The colloid injected from the first through hole 221 flows at a consistent speed along the channel of the second part 22 to both sides of the second through hole 222. The fact that the first through hole 221 is equidistant from the two adjacent second through holes 222 allows for simultaneous observation of whether both sides of each first through hole 221 have been filled with colloid, thus improving the accuracy of the amount of colloid injected.

[0075] In some embodiments, the distance between each first through hole 221 and each adjacent second through hole 222 is the same. This way, when adhesive is poured through the first through hole 221, adhesive can be observed overflowing from each second through hole 222 simultaneously, improving the convenience and accuracy of determining whether adhesive pouring is complete.

[0076] In some embodiments, such as Figure 8 As shown, the middle frame 2 includes two opposite long sides, each of which has a first through hole 221 and a second through hole 222.

[0077] In other words, the middle frame 2 has two first through holes 221 and two second through holes 222, and each long side has one first through hole 221 and one second through hole 222. This fully utilizes the advantage of fast colloid injection speed on the two long sides.

[0078] In some embodiments, the second part 22 may have a plurality of first through holes 221. The plurality of first through holes 221 may be distributed on the long side of the middle frame 2, or distributed on the short side of the middle frame 2, or distributed on both the long side and the short side of the middle frame 2.

[0079] In some embodiments, the second part 22 may have a plurality of second through holes 222. The plurality of second through holes 222 may be distributed on the long side of the middle frame 2, or distributed on the short side of the middle frame 2, or distributed on both the long side and the short side of the middle frame 2.

[0080] The size and shape of the first through hole 221 and the second through hole 222 can be the same or different, and those skilled in the art can set them as needed.

[0081] In some embodiments, the screen assembly includes an earpiece that at least partially fills the space between the screen 1 and the second part 22, and the connector 4 is positioned to avoid the earpiece. This prevents the connector 4 from exerting excessive pressure on the earpiece, which could damage the earpiece or cause the screen 1 to be squeezed out of the mid-frame 2.

[0082] This disclosure also proposes a terminal device, which includes the screen component of this disclosure.

[0083] In this disclosure, the screen of the terminal device is connected to the mid-frame via a connector that closes around the screen's circumference. This significantly reduces the width of the non-display area, increases the screen-to-body ratio, and provides users with a better user experience. Furthermore, it eliminates the need for a separate process to apply adhesive or sealant around the screen, simplifying the manufacturing process and saving time.

[0084] This disclosure also proposes a method for assembling a screen assembly, such as... Figure 9 As shown, the steps are as follows:

[0085] S101: A resistive part is formed in the second part, extending along the edge of the second part and closing therein;

[0086] S102: Fix the screen to the mid-frame so that the back of the screen and the adhesive part abut against each other;

[0087] S103: A connector is formed by injecting colloid through the first through hole so that at least the connector connects the periphery of the screen and the first part.

[0088] In the embodiments of this disclosure, a connector is formed by injecting adhesive into the first potting hole to connect the periphery of the screen and the first part. This eliminates the need for additional adhesive application between the screen and the mid-frame, effectively reducing the width of the non-display area and increasing the screen-to-body ratio. Furthermore, the process is simple, saving both process and time costs.

[0089] In some embodiments, forming a barrier portion extending along the edge of the second part and closing it includes: bonding several segments to the second part respectively to form a circumferentially closed barrier portion.

[0090] like Figure 10 As shown, for example:

[0091] S201: Several segments are bonded to the second part to form a circumferentially closed adhesive barrier part;

[0092] S202: Fix the screen to the mid-frame so that the back of the screen and the adhesive part abut against each other;

[0093] S203: A connector is formed by injecting colloid through the first through hole so that at least the connector connects the periphery of the screen and the first part.

[0094] In embodiments of this disclosure, several segments bonded to the second part are formed into adhesive-resistant portions, and the size of the formed adhesive-resistant portions can be adjusted to accommodate different specifications of the mid-frame and screen.

[0095] In some embodiments, forming a connector by injecting colloid through a first through-hole to connect at least the periphery of the screen and the first part includes: the second part having a second through-hole, injecting colloid through the first through-hole to cover the first through-hole and the colloid overflowing from the second through-hole to form a connector, the connector filling the space between the screen, the first part, and the second part.

[0096] like Figure 11 As shown, for example:

[0097] S301: A resistive part is formed in the second part, extending along the edge of the second part and closing therein;

[0098] S302: Fix the screen to the mid-frame so that the back of the screen and the adhesive part abut against each other;

[0099] S303: Glue is injected through the first through hole until it covers the first through hole and the glue overflows from the second through hole to form a connector.

[0100] In the embodiments of this disclosure, the colloid is injected until it covers the first through hole and overflows from the second through hole, so that the colloid completely fills the space between the middle frame, the screen and the adhesive barrier. The connector formed by the colloid is simultaneously connected to the first part and the second part of the middle frame as well as the bottom surface and the periphery of the screen, providing strong fixing force and sealing for the screen and the middle frame.

[0101] In some embodiments, forming a connector by injecting colloid through a first through-hole includes: injecting colloid into the periphery of the screen, the back of the screen, and between the first part and the second part through the first through-hole; and heating the screen assembly after injecting the colloid until the injected colloid cures to form a connector.

[0102] like Figure 12 As shown, for example:

[0103] S401: A resistive portion is formed in the second part, extending along the edge of the second part and closing therein;

[0104] S402: Fix the screen to the mid-frame so that the back of the screen and the adhesive part abut against each other;

[0105] S403: Inject colloid into the periphery of the screen, the back of the screen, and between the first part and the second part through the first through hole;

[0106] S404: Heat the screen assembly after the colloid is injected until the injected colloid cures to form a connector.

[0107] The adhesive poured between the screen and the mid-frame is difficult to contact with light and air, making it difficult to effectively cure using techniques such as light curing and oxygen-based curing. By selecting a thermosetting adhesive and employing a thermosetting process, the poured adhesive can be ensured to cure quickly and reliably into a connector.

[0108] This disclosure also proposes an assembly line for screen components. The assembly line refers to a collection of equipment used to assemble the screen components of this disclosure, such as various jigs for assembling screen components and equipment (such as conveyor belts or transport vehicles, robotic arms, etc.) for moving between the jigs. The jigs can be distributed across multiple workstations or integrated into one workstation.

[0109] In some embodiments, the screen assembly line includes a fixture, a fixing fixture, and a potting fixture. The fixture forms a resistive portion 3 extending along the edge of the second portion 22 and closing thereafter. The fixing fixture secures the screen 1 to the mid-frame 2 such that the resistive portion 3 abuts against the back of the screen 1 and the second portion 22, respectively. The potting fixture injects adhesive through a first through-hole 221 to form a connector 4, such that the connector 4 at least connects the periphery of the screen 1 and the first portion 21.

[0110] In the embodiments of this disclosure, adhesive is injected through the first through-hole 221 into the space between the middle frame 2 and the screen 1 using a potting fixture to form a connector 4. This effectively connects the screen 1 and the middle frame 2 and achieves a good sealing effect. Furthermore, no further adhesive application is required between the screen 1 and the middle frame 2, which effectively reduces the width of the non-display area.

[0111] In some embodiments, the execution fixture forms an adhesive-blocking portion 3 extending along the edge of the second part 22 and closing by the following steps: several segments 31 are respectively bonded to the second part 22, and the several segments 31 are connected end to end in sequence to form a circumferentially closed adhesive-blocking portion 3.

[0112] In the embodiments of this disclosure, the adhesive resisting part 3 is formed by several segments 31 bonded to the second part 22. The shape and size of the adhesive resisting part 3 can be adjusted according to the different specifications of the middle frame 2 and screen 1, so as to be suitable for mobile phones of different specifications.

[0113] In some embodiments, the glue-filling fixture forms the connector 4 by filling glue through the first through hole 221 through the following steps, so that the connector 4 connects at least the periphery of the screen 1 and the first part 21:

[0114] The second part 22 has a second through hole 222. Glue is injected through the first through hole 221 until it covers the first through hole 221 and the glue overflows from the second through hole 222 to form a connector 4.
