Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, and in particular to screen modules and electronic devices. Background Technology

[0002] LIPO (Low-Injection Pressure Overmolding) technology uses liquid polymer materials to encapsulate the ribbon cable connections of the screen module. After the polymer material solidifies, it is tightly bonded to the main functional structure of the screen module and the frame of the electronic device. LIPO technology can cleverly "hide" components such as the driver chip and circuitry of the screen module. Compared with traditional COG (Chip on Glass) and COF (Chip on Film) packaging technologies, it can reduce the space occupied by the bezel, thereby achieving a narrower bezel effect.

[0003] In the LIPO process, damming adhesive forms a physical barrier during injection molding, preventing liquid LIPO adhesive from overflowing into areas that don't need filling. This ensures the accuracy and reliability of the encapsulation, avoiding display abnormalities such as stains, color differences, or uneven brightness in the screen module. However, damming adhesive itself has low surface energy and poor wetting properties with the bonded surfaces. After curing, it is prone to detachment during transportation and mechanical tests such as drops and vibrations. Detached damming adhesive can cause problems such as screen flickering or blackouts due to movement within the screen assembly and impacts on the screen. Utility Model Content

[0031] LIPO (Low-Injection Pressure Overmolding) technology uses liquid polymer materials to encapsulate the ribbon cable connections of the screen module. After curing, the polymer material is tightly bonded to the main functional structure of the screen module and the frame of the electronic device. LIPO technology can cleverly "hide" components such as the driver chip and circuitry of the screen module, reducing the space occupied by the bezel compared to traditional COG (Chip on Glass) and COF (Chip on Film) packaging technologies, thus achieving a narrower bezel effect. In the LIPO process, the damming adhesive forms a physical barrier during injection molding, preventing the liquid LIPO adhesive from overflowing into areas that do not need to be filled, thereby ensuring the accuracy and reliability of the encapsulation and avoiding display abnormalities such as stains, color differences, or uneven brightness in the screen module. However, the damming adhesive itself has low surface energy and poor wettability with the bonded surface, making it prone to detachment during subsequent transportation and mechanical tests such as drops and vibrations after curing. Detached damming adhesive can cause problems such as screen flickering and blackouts due to movement within the screen compartment and impact with the screen.

[0032] This disclosure provides a screen module, Figure 1 This is a partial structural schematic diagram of an electronic device according to an exemplary embodiment of the present disclosure, such as... Figure 1 As shown, the screen module 1 includes a main structure 11 and an encapsulation component 12. The main structure 11 includes a functional body 111. The encapsulation component 12 includes an encapsulation body 121, a barrier body 122, and a detachable structure 123. The main structure 11 has an encapsulation area 113, an inner area 114, and an intermediate area 115 connecting the encapsulation area 113 and the inner area 114. The encapsulation body 121 is located in the encapsulation area 113, the functional body 111 is located in the inner area 114, and the barrier body 122 is located in the intermediate area 115 to separate the encapsulation area 113 and the inner area 114. The detachable structure 123 is detachably connected to the main structure 11, and at least a portion of the barrier body 122 is fixedly connected to the detachable structure 123.

[0033] The encapsulation component 12 of the aforementioned screen module 1 includes an encapsulation body 121, a barrier body 122, and a detachable structure 123. The barrier body 122 can separate the encapsulation area 113 from the internal area 114, preventing the encapsulation body 121 from interfering with the functional main body 111 located in the internal area 114. The detachable structure 123 is detachably connected to the main structure 11. After the barrier body 122 has completed its function, it can be removed using the detachable structure 123, preventing the barrier body 122 from falling off during subsequent assembly, testing, transportation, or use and affecting the function of the screen module 1.

[0034] It should be noted that the aforementioned functional body 111 can be a component in the screen module 1 used to implement screen functions such as display, touch, and fingerprint recognition. The aforementioned package 121 can be used to encapsulate components such as ribbon cables and chips in the screen module 1, and can also be set at specific locations in the screen module 1 to serve functions such as sealing, connection, and structural reinforcement. For example, the main structure 11 can include a control component 112 electrically connected to the functional body 111, and the package 121 covers the control component 112, thus encapsulating the control component 112. The control component 112 can include ribbon cables and chips located between the functional body 111 and the frame 21 of the electronic device 2. When encapsulating the ribbon cables and chips, the package 121 can also connect the functional body 111 to the frame 21 using the structure of the package 121.

[0035] In the embodiments of this disclosure, the encapsulation body 121 is made of a cured liquid polymer material, and the encapsulation body 121 is formed by low-pressure injection molding. Low-temperature injection molding of the liquid polymer material can encapsulate the control component 112 of the screen module 1, reducing the space occupied by the bezel and thus achieving a narrower bezel effect. The barrier body 122 includes a damming colloid, which can be made of silicone-based adhesive or other materials; this disclosure does not limit this. Alternatively, the encapsulation body 121 and the barrier body 122 can also be made of other materials capable of encapsulation or barrier; this disclosure does not limit this.

[0036] In some embodiments, such as Figure 2 As shown, the removal structure 123 includes a protective film layer exposed outside the main structure 11. The protective film layer has a partition structure 1233, which divides the protective film layer into a protective functional area 1231 and a tear-off area 1232. The partition structure 1233 includes a disconnection area, and the barrier 122 is fixedly connected to the tear-off area 1232. By using the protective film layer on the outside of the main structure 11 as the removal structure 123, the structural complexity and the space occupied by the additional removal structure 123 are reduced. The partition structure 1233 of the protective film layer has a disconnection area, which facilitates the subsequent disconnection and removal of the tear-off area 1232 relative to the protective functional area 1231.

[0037] The separation structure 1233 can be arranged at intervals to form a structure that is easy to tear, or the separation area can be arranged in an array to form a structure that is easy to tear.

[0038] In the above embodiment, the tear-off area 1232 includes a connecting portion 1232a and a tear-handle portion 1232b extending from the connecting portion 1232a, with the barrier 122 fixedly connected to the connecting portion 1232a. Because the barrier 122 is fixedly connected to the connecting portion 1232a, pulling the tear-handle portion 1232b can cause the connecting portion 1232a and the barrier 122 to separate together from the protective functional area 1231. The tear-handle portion 1232b also improves the ease of operation in the tear-off area 1232 removal process.

[0039] In some embodiments, the aforementioned protective film layer can be an insulating film. The insulating film in the screen module 1 can protect the electronic components of the screen module 1 and prevent interference caused by contact with external components. By using the insulating film to set up the removal structure 123, additional structural and functional interference to the screen module 1 is reduced, and the removal operation is also facilitated.

[0040] In some embodiments, the main structure 11 includes a heat dissipation structure 116 exposed on the main structure 11, and at least a portion of the barrier 122 is connected to the heat dissipation structure 116. The heat dissipation structure 116 on the outside of the main structure 11 can be used to dissipate heat from the screen module 1. The connection between the heat dissipation structure 116 and the barrier 122 reduces additional structural and functional interference to the screen module 1 and facilitates the separation of the barrier 122 from the heat dissipation structure 116. The heat dissipation structure 116 can be made of metal, such as copper foil or stainless steel, and can also form electromagnetic shielding for the screen module 1 to prevent electromagnetic interference. Furthermore, when the heat dissipation structure 116 is metal, it can also provide structural support for the screen module 1, improving the structural reliability of the screen module 1.

[0041] In some embodiments, the heat dissipation structure 116 includes at least one groove 1161, and the barrier 122 engages with the groove 1161 to form a glue-holding structure, thereby improving the glue-holding effect.

[0042] The removal structure 123 includes a tearing handle portion 1232b extending along a first direction, and the groove 1161 includes a strip-shaped structure extending along the first direction, so that the barrier adhesive can separate from the groove 1161 along the first direction when the tearing handle is pulled, thereby avoiding adhesive residue.

[0043] This disclosure further provides an electronic device 2, which includes the screen module 1 described above.

[0044] The encapsulation component 12 of the screen module 1 includes an encapsulation body 121, a barrier 122, and a detachable structure 123. The barrier 122 can separate the encapsulation area 113 from the internal area 114, preventing the encapsulation body 121 from interfering with the functional main body 111 located in the internal area 114. The detachable structure 123 is detachably connected to the main structure 11. After the barrier 122 has completed its function, it can be removed using the detachable structure 123, preventing the barrier 122 from falling off during subsequent assembly, testing, transportation, or use and affecting the function of the screen module 1.

[0045] The electronic device 2 includes a mid-frame 21. When the encapsulation body 121 is made of a cured liquid polymer material, and the encapsulation body 121 is formed by low-pressure injection molding, the mid-frame 21 can be fixed to the main structure 11 of the screen module 1 during the curing process. The liquid polymer material, through low-temperature injection molding, can encapsulate the control components 112 of the screen module 1, reducing the space occupied by the bezel and thus achieving a narrower bezel effect.

[0046] The aforementioned electronic device 2 may be a mobile terminal such as a mobile phone, tablet computer, vehicle terminal, medical terminal, or wearable device, or it may be a vehicle, mobile cleaning equipment, robot, etc. This disclosure does not impose any restrictions on it.

[0047] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure in any way. Although this disclosure has been disclosed above with reference to a preferred embodiment, it is not intended to limit this disclosure. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this disclosure.
