[0040] Please refer to Figure 1 and Figure 2 In the embodiments, the display module 100 includes a glass panel 10, a display mechanism 20, a conductive connecting piece 30, a first soft rubber piece 40 and a hard rubber piece 50.

[0041] The display mechanism 20 is laminated on the glass panel 10, and includes a laminated display assembly 21 and a support assembly 22, the display assembly 21 is laminated on the glass panel 10, and the support assembly 22 is located on the upper surface of the display assembly 21.

[0042] One end of the conductive connecting piece 30 is connected with the display assembly 21, and the other end of the conductive connecting piece 30 is bent and connected with the support assembly 22 to form a receiving hole 31.

[0043] The first soft glue piece 40 wraps the side wall of the display mechanism 20 and fills the receiving hole 31. The hard glue piece 50 covers the display mechanism 20 and the first soft glue piece 40.

[0044] Specifically, the conductive connecting piece 30 can be a flat cable or a flat cable, the first soft glue piece 40 is formed by pouring and solidifying a first liquid glue (not shown in the figure) with a lower Shore hardness, and the hard glue piece 50 is formed by pouring and solidifying a second liquid glue (not shown in the figure) with a higher Shore hardness.

[0045] In this way, the display module 100 of the embodiment of the present application is wrapped by the first soft glue piece 40 through the conductive connecting piece 30, the display mechanism 20 and the first soft glue piece 40 are covered by the hard glue piece 50, the hard glue piece 50 can meet the assembly requirements of the display module 100, the area of the conductive connecting piece 30 is protected by the first soft glue piece 40, when the display module 100 is impacted by the outside world, the first soft glue piece 40 can effectively absorb the impact kinetic energy, reduce the probability of fracture failure of the conductive connecting piece 30, thereby prolonging the service life of the display module 100. In the embodiment, the display assembly 21 includes a first optical glue layer 211, a polarizer 212, a second optical glue layer 213, a touch feedback piece 214 and a display panel 215 which are sequentially laminated, and the first optical glue layer 211 is located between the polarizer 212 and the glass panel 10. The support assembly 22 includes a first adhesive tape layer 221, a metal plate 222, a foam layer 223, a second adhesive tape layer 224 and a metal piece 225 which are sequentially laminated, and the first adhesive tape layer 221 is located between the display panel 215 and the metal plate 222. One end of the conductive connecting piece 30 is connected with the touch feedback piece 214 and the display panel 215, the other end of the conductive connecting piece 30 is inserted between the foam layer 223 and the second adhesive tape layer 224 after being bent, and then extends to the side of the metal piece 225 away from the second adhesive tape layer 224 through the second adhesive tape layer 224 and the metal piece 225, thereby facilitating connection with the processor (not shown in the figure) of the terminal 2000.

[0046] The metal piece 225 can be made of one or more of iron, titanium, aluminum, and steel. The metal piece 225 is in the shape of a square ring, and the hard rubber piece 50 and the first soft rubber piece 40 can also be in the shape of a square ring. The hard rubber piece 50 covers the upper surface of the first soft rubber piece 40 and the upper surface of the metal piece 225. Optionally, the hard rubber piece 50 covers part of the upper surface of the metal piece 225, and the other part of the upper surface of the metal piece 225 is exposed, so as to be used for welding a small metal piece later.

[0047] The first optical adhesive layer 211 is used to bond the polarizer 212 and the glass panel 10. The polarizer 212 is used to scatter light, so that the user can see the content displayed by the display panel 215. The second optical adhesive layer 213 is used to bond the touch feedback piece 214 and the polarizer 212. The touch feedback piece 214 collects touch signals by using a pressing sensing. The display panel 215 is used for picture display. The first adhesive tape layer 221 is used to fix the metal plate 222. The metal plate 222 is used to protect the touch feedback piece 214 and the display panel 215.

[0048] During use, the touch feedback piece 214 receives the touch signal of the user, and then feeds back the signal to the processor through the conductive connecting piece 30. The processor processes the signal and feeds back the processed signal to the display panel 215 through the conductive connecting piece 30 for display, so as to achieve the use effect.

[0049] Please refer to Figure 3 , Figure 4 and Figure 5 In some other embodiments, the first soft rubber piece 40 can not be in the shape of a square ring. Specifically, the first soft rubber piece 40 includes a strip-shaped soft rubber part 41, which wraps a side wall of the display mechanism 20. Specifically, the strip-shaped soft rubber part 41 wraps the side wall of the display mechanism 20, which protrudes with the conductive connecting piece 30, so as to wrap the conductive connecting piece 30 and fill the receiving hole 31. When the display module 100 is impacted by the outside, the strip-shaped soft rubber part 41 outside the conductive connecting piece 30 and the strip-shaped soft rubber part 41 in the receiving hole 31 can effectively absorb the impact kinetic energy, reduce the probability of fracture failure of the conductive connecting piece 30, and thus improve the service life of the display module 100.

[0050] Please refer to Figure 6In some other embodiments, the first soft glue member 40 can be formed by multiple segments of glue, and specifically, the first soft glue member 40 further includes two arc-shaped soft glue portions 42, which respectively wrap two arc-shaped corner side walls 216 of the display assembly 21; and two ends of the strip-shaped soft glue portion 41 are respectively connected to the two arc-shaped soft glue portions 42.

[0051] Specifically, the arc-shaped soft glue portion 42 is located at a corner position of the display assembly 21, and the upper surface of one side of the glass panel 10 receives the arc-shaped soft glue portion 42. Since the corner area is also an area where the display module 100 is more likely to fail due to impact, by wrapping the arc-shaped corner side wall 216 of the display assembly 21 with the arc-shaped soft glue portion 42, the impact kinetic energy can be effectively absorbed, and the probability of failure of the display module 100 at the corner due to impact can be reduced, thereby facilitating the improvement of the service life of the display module 100.

[0052] Please refer to Figure 5 and Figure 6 again, in the embodiment, the hard glue member 50 includes a ring-shaped hard glue portion 51 and a U-shaped hard glue portion 52. The ring-shaped hard glue portion 51 covers at least part of the upper surface of the first soft glue member 40 and the support assembly 22; and the U-shaped hard glue portion 52 is connected between the ring-shaped hard glue portion 51 and the glass panel 10, and wraps the side walls of the display mechanism 20 connected in sequence.

[0053] Specifically, the U-shaped hard glue portion 52 is located below and connected to the ring-shaped hard glue portion 51, the ring-shaped hard glue portion 51 covers the upper surface of the first soft glue member 40 and the edge area of the upper surface of the support assembly 22, and the U-shaped hard glue portion 52 wraps the other three side walls of the display mechanism 20 except the protruding conductive connecting member 30. In this way, the ring-shaped hard glue portion 51 and the U-shaped hard glue portion 52 effectively support and protect the first soft glue member 40 and the display mechanism 20, guarantee the assembly requirement of the display module 100, and improve the service life of the display module 100.

[0054] In the embodiment, the side wall of the support assembly 22 has two side recesses 2261, and the support assembly 22 has two through holes 2262, which are respectively communicated with the two side recesses 2261 to form two limiting pull glue cavities 226. The display module 100 further includes a second soft glue member 60, which fills the two limiting pull glue cavities 226 and extends to wrap part of the side wall of the display mechanism 20 to be connected with the strip-shaped soft glue portion 41.

[0055] Specifically, the two side recesses 2261 are respectively located at two corners of the support assembly 22 close to the conductive connecting member 30, and are formed by inward recessing of the second adhesive tape layer 224, and the two through holes 2262 are both formed on the metal member 225 and communicated with the corresponding side recess 2261.

[0056] When the display module 100 is filled with glue, first, the third liquid glue (not shown in the figure) is filled into the two limiting glue pulling cavities 226, so that the third liquid glue wraps the part of the side wall of the display mechanism 20 close to the corner of the conductive connecting piece 30, and then the first liquid glue is filled to form the first soft glue part after the second soft glue part 60 is formed by the solidification of the third liquid glue. Since the side walls of each part of the support assembly 22 are uneven, when the first liquid glue is filled, the first liquid glue is easy to overflow from the gap of the side wall of the support assembly 22. By arranging two second soft glue parts 60, the two ends can be blocked when the first liquid glue is filled, thereby improving the fullness of the first liquid glue after being filled, and further improving the wrapping and protection effect of the first soft glue part on the conductive connecting piece 30. In addition, the second soft glue part 60 can also protect the two corners of the support assembly 22 close to the conductive connecting piece 30, thereby facilitating the improvement of the service life of the display module 100. The through hole 2262 is arranged to facilitate the use of a glue needle (not shown in the figure) to fill the third liquid glue into the side recess 2261, and the through hole 2262 also has the effect of fixing the second soft glue part 60, avoiding the second soft glue part 60 from being pulled out of the limiting glue pulling cavity 226 when the display module 100 is demolded.

[0057] In the embodiment, the hardness range of the first soft glue part 40 can be Shore 60HA-65HA, the hardness range of the second soft glue part 60 can be Shore 40HA-45HA, and the hardness of the hard glue part 50 is greater than or equal to Shore 75HD.

[0058] In this way, the hard glue part 50 can still remain within the hardness range of the engineering plastic, thereby ensuring that the display module 100 meets the assembly requirements. The first soft glue part 40 and the second soft glue part 60 are within a reasonable hardness range and have good elasticity, thereby being able to protect the conductive connecting piece 30 and the two corners of the support assembly 22 close to the conductive connecting piece 30, respectively, thereby facilitating the improvement of the service life of the display module 100.

[0059] In the embodiment, the thermal expansion coefficient of the first soft glue part 40 ranges from 50ppm to 120ppm. Since the first soft glue part 40 wraps around the conductive connecting piece 30, if the thermal expansion coefficient of the first soft glue part 40 is too high, the travel distance of the first soft glue part 40 pulling the conductive connecting piece 30 when it is heated and expanded is large, thereby easily leading to the fracture of the conductive connecting piece 30. By arranging the first soft glue part 40 to have a smaller thermal expansion coefficient, the travel distance of the first soft glue part 40 pulling the conductive connecting piece 30 when it is heated and expanded is small, thereby reducing the risk of fracture of the conductive connecting piece 30, and further facilitating the improvement of the service life of the display module 100.

[0060] Please refer to Figure 2In some other embodiments, the strip-shaped soft glue part 41 can be formed with a plurality of spaced grooves 411, and the annular hard glue part 51 fills the grooves 411. The provision of the grooves 411 increases the contact area and the bonding force between the strip-shaped soft glue part 41 and the annular hard glue part 51, thereby improving the firmness of the strip-shaped soft glue part 41 and the annular hard glue part 51 after bonding.

[0061] Please refer to Figure 7 , Figure 8 and Figure 9 , the embodiment of the present application also provides a display module encapsulation method for encapsulating the display module 100. The display module 100 comprises a conductive connecting piece 30, a glass panel 10 and a display mechanism 20 which are sequentially stacked, the display mechanism 20 comprises a display assembly 21 and a support assembly 22 which are stacked, the display assembly 21 is stacked on the glass panel 10, one end of the conductive connecting piece 30 is connected with the display assembly 21, and the other end of the conductive connecting piece 30 is bent to be connected with the support assembly 22 to form a receiving hole 31. The display module encapsulation method comprises the following steps:

[0062] Step S1, sealing the display module 100 in a first jig 1000, so that the display mechanism 20 and the inner side wall of the first jig 1000 form a first forming cavity (not shown in the figure).

[0063] Step S2, pouring a first liquid glue into the first forming cavity, so that the first liquid glue wraps the side wall of the display mechanism 20, and the first liquid glue flows into the receiving hole 31 from the first forming cavity.

[0064] Specifically, a glue pouring needle is inserted into the first forming cavity from the first jig 1000, so that the first liquid glue is poured into the first forming cavity.

[0065] Step S3, curing the first liquid glue to form a first soft glue part 40.

[0066] Specifically, the first liquid glue can be cured by a UV light curing instrument (not shown in the figure) to form the first soft glue part 40.

[0067] Step S4, sealing the display module 100 formed with the first soft glue part 40 in a second jig (not shown in the figure), so that the first soft glue part 40 and the display mechanism 20 both form a second forming cavity (not shown in the figure) with the inner wall of the second jig.

[0068] Specifically, the structure of the second jig can be similar to that of the first jig 1000, and part of it is different, for example, the second forming cavity is different from the first forming cavity, and it is arranged according to the shape of the hard glue part 50 to be formed and the shape of the first soft glue part 40.

[0069] Step S5, pouring the second liquid glue into the second molding cavity so that the second liquid glue covers the display mechanism 20 and the first soft glue part 40.

[0070] Specifically, the glue pouring needle is used to insert the second molding cavity from the second jig, so as to pour the second liquid glue into the second molding cavity.

[0071] Step S6, curing the second liquid glue to form the hard glue part 50.

[0072] Specifically, the UV light curing instrument (not shown in the figure) can be used to cure the second liquid glue to form the hard glue part 50. The compositions and proportions of the first liquid glue and the second liquid glue are different.

[0073] The display module encapsulation method of the embodiment of the application pours the first liquid glue and the second liquid glue into the first molding cavity and the second molding cavity respectively to form the first soft glue part 40 and the hard glue part 50, and the first liquid glue wraps the side wall of the display mechanism 20, and the second liquid glue covers the display mechanism 20 and the first soft glue part 40. The conductive connecting part 30 of the display module 100 after glue molding is wrapped by the first soft glue part 40, the upper surface of the display mechanism 20 and the upper surface of the first soft glue part 40 are covered by the hard glue part 50, the hard glue part 50 can meet the assembly requirements of the display module 100, the area of the conductive connecting part 30 is protected by the first soft glue part 40, when the display module 100 is impacted by the outside world, the first soft glue part 40 outside the conductive connecting part 30 and the first soft glue part 40 in the receiving hole 31 can effectively absorb the impact kinetic energy, reducing the probability of fracture failure of the conductive connecting part 30, thereby prolonging the service life of the display module 100.

[0074] In the embodiment, the first molding cavity of the first jig 1000 can be in a strip shape, so that the first soft glue part 40 after molding and curing is in a strip shape, the first soft glue part 40 after molding and curing is stably sealed on the side of the display mechanism 20 protruding with the conductive connecting part 30, and the first soft glue part 40 after molding and curing wraps and protects the conductive connecting part 30. In other embodiments, the first molding cavity of the first jig 1000 can also be in a ring shape, so that the first soft glue part 40 is in a ring shape, and the first soft glue part 40 covers the circumferential side of the display mechanism 20 and wraps the conductive connecting part 30, which is not limited in the embodiment of the application.

[0075] In some embodiments, as shown in Figure 9 The first molding cavity includes a side molding cavity 1001; in step S1, the display mechanism 20 and the inner side wall of the first jig 1000 form the first molding cavity, which specifically includes that one side wall of the display mechanism 20 and one inner side wall of the first jig 1000 form the side molding cavity 1001. In step S2, the step of wrapping the side wall of the display mechanism 20 with the first liquid glue specifically includes wrapping one side wall of the display mechanism 20 with the first liquid glue.

[0076] Since only one of the four peripheral sidewalls of the display mechanism 20 protrudes with the conductive connecting piece 30, the first liquid glue can be used to encapsulate only one side of the display mechanism 20 with the conductive connecting piece 30. Specifically, the part of the conductive connecting piece 30 protruding from the sidewall of the display mechanism 20 is accommodated in the side forming cavity 1001, which is in the form of a strip. When the first liquid glue is poured into the side forming cavity 1001 and solidified, a strip-shaped soft glue part 41 of the first soft glue piece 40 matching the shape of the side forming cavity 1001 can be formed, which wraps the sidewall of the display mechanism 20 protruding with the conductive connecting piece 30, thereby wrapping the conductive connecting piece 30. When the display module 100 is impacted by external impact, the strip-shaped soft glue part 41 can effectively absorb the impact kinetic energy, reducing the probability of failure of the conductive connecting piece 30, thereby prolonging the service life of the display module 100.

[0077] Further, the first forming cavity further includes two arc forming cavities 1002, which are respectively communicated with two ends of the side forming cavity 1001, and the height of the arc forming cavity 1002 is less than that of the side forming cavity 1001.

[0078] In step S1, the display mechanism 20 and the inner sidewall of the first jig 1000 form the first forming cavity, which specifically includes that the two arc-shaped corner sidewalls 216 of the display assembly 21 respectively form two arc forming cavities 1002 with the two arc-shaped corner inner sidewalls (not shown in the figure) of the first jig 1000.

[0079] In step S2, the step of wrapping the sidewall of the display mechanism 20 with the first liquid glue further includes that the first liquid glue also wraps the two arc-shaped corner sidewalls 216 of the display assembly 21.

[0080] Specifically, the two arc forming cavities 1002 are relatively small in size. When the first liquid glue is poured into the side forming cavity 1001, the first liquid glue overflows from the side forming cavity 1001 to the two arc forming cavities 1002. When the first liquid glue solidifies, two arc-shaped soft glue parts 42 of the first soft glue piece 40 can be formed. Since the corner area is also an area that is prone to failure due to impact, by wrapping the two arc-shaped corner sidewalls 216 of the display assembly 21 with the first liquid glue, the impact kinetic energy can be effectively absorbed after the arc-shaped soft glue parts 42 are formed, thereby reducing the probability of failure of the display module 100 at the corner area due to impact, thereby facilitating the improvement of the service life of the display module 100.

[0081] In this embodiment, the first liquid glue only wraps the two arc-shaped corner sidewalls 216 of the display assembly 21, but does not wrap the corner parts of the support assembly 22, thereby reserving space for the second liquid glue to wrap the two corner parts of the support assembly 22.

[0082] In the embodiment, the display mechanism 20 further includes three side walls connected in sequence to form the U-shaped side wall 23; the second forming cavity includes a U-shaped forming cavity (not shown in the figure) and a ring-shaped forming cavity (not shown in the figure) connected in sequence. In step S4, the first soft rubber part 40 and the display mechanism 20 are both formed with the second forming cavity of the inner wall of the second jig, which specifically includes:

[0083] In step S41, the upper surface of the first soft rubber part 40 and at least part of the upper surface of the support assembly 22 are both formed with the ring-shaped forming cavity of the top wall of the second jig.

[0084] In step S42, the three side walls of the display mechanism 20 connected in sequence are formed with the U-shaped forming cavity of the three side walls of the second jig.

[0085] In step S5, the second liquid rubber covers the display mechanism 20 and the first soft rubber part 40, which specifically includes that the second liquid rubber covers the upper surface of the first soft rubber part 40 and part of the upper surface of the support assembly 22, and wraps the U-shaped side wall 23 of the display mechanism 20.

[0086] Specifically, the three side walls connected to form the U-shaped side wall 23 are respectively the other three side walls of the display mechanism 20 except for the side wall with the protruding conductive connecting part 30. After the second liquid rubber is poured into the U-shaped forming cavity and the ring-shaped forming cavity and solidified, the ring-shaped hard rubber part 51 and the U-shaped hard rubber part 52 of the hard rubber part 50 can be formed, and the ring-shaped hard rubber part 51 covers the upper surface of the first soft rubber part 40 and the edge area of the upper surface of the support assembly 22, and the U-shaped hard rubber part 52 wraps the other three side walls of the display mechanism 20 except for the protruding conductive connecting part 30. The ring-shaped hard rubber part 51 and the U-shaped hard rubber part 52 effectively support and protect the first soft rubber part 40 and the display mechanism 20, guarantee the assembly requirement of the display module 100, and improve the service life of the display module 100.

[0087] In the embodiment, the side wall of the support assembly 22 has two side recesses 2261, and the support assembly 22 has two through holes 2262 in communication with the two side recesses 2261 to form two limiting rubber pulling cavities 226. The display module sealing method further includes:

[0088] In step S7, the display module 100 is sealed in a third jig (not shown in the figure) to form a limiting rubber pulling forming cavity (not shown in the figure) of the inner side wall of the third jig with the two limiting rubber pulling cavities 226 of the support assembly 22.

[0089] In step S8, the third liquid rubber (not shown in the figure) is poured into the limiting rubber pulling forming cavity to fill the two limiting rubber pulling cavities 226 of the support assembly 22 and extend to wrap part of the side wall of the display mechanism 20, so as to limit the pouring of the first liquid rubber into the first forming cavity.

[0090] Step S9, curing the third liquid glue to form the second soft glue part 60.

[0091] The third liquid glue can be cured by a UV light curing instrument (not shown in the figure) to form the second soft glue part 60.

[0092] Specifically, the two side recesses 2261 are respectively located at the two corners of the support assembly 22 close to the conductive connecting piece 30, and the two side recesses 2261 are formed by the second adhesive tape layer 224 being recessed inwardly, and the two through holes 2262 are both arranged on the metal piece 225 and communicate with the corresponding side recesses 2261.

[0093] When the display module 100 is filled with glue, first, steps S7-S9 are performed, the glue filling needle is inserted into the through hole 2262 from the third jig to fill the third liquid glue into the limiting pull glue forming cavity, so that the third liquid glue wraps the part of the side wall of the display mechanism 20 close to the corner of the conductive connecting piece 30, and then steps S1-S6 are performed after the third liquid glue is cured to form the second soft glue part 60. Since the two second soft glue parts 60 are blocked at the two ends of the first forming cavity when the first liquid glue is filled, the fullness of the first liquid glue filled into the first forming cavity is improved, and the wrapping and protection effect of the first soft glue part on the conductive connecting piece 30 is improved. In addition, the second soft glue part 60 can also protect the two corners of the support assembly 22 close to the conductive connecting piece 30, thereby facilitating the improvement of the service life of the display module 100. The through hole 2262 is arranged to facilitate the filling of the third liquid glue into the side recess 2261 by the glue needle (not shown in the figure), and the through hole 2262 also has the function of fixing the second soft glue part 60, avoiding the second soft glue part 60 from being pulled out of the limiting pull glue cavity 226 when the display module 100 is demolded.

[0094] In the embodiment, the first jig 1000 has a plurality of spaced protrusions on the top (not shown in the figure), so that the first soft glue part 40 formed after the first liquid glue is filled into the first forming cavity and cured has a plurality of spaced recesses 411, and the second liquid glue fills the recesses 411 when the second liquid glue is filled into the second forming cavity.

[0095] In this way, it is convenient to form a plurality of spaced recesses 411 on the side wall of the first soft glue part 40 in contact with the hard glue part 50 after forming. The arrangement of the recesses 411 increases the contact area and bonding force of the first soft glue part 40 and the hard glue part 50, thereby improving the firmness of the first soft glue part 40 and the hard glue part 50 after bonding.

[0096] Please refer to Figure 10 and Figure 11The terminal 2000 provided by the embodiment of the present application comprises a middle frame 700 and the display module 100 as described above, the display module 100 is arranged in the middle frame 700, and the corner part between the middle frame 700 and the display module 100 has a clearance space 710.

[0097] The terminal 2000 provided by the embodiment of the present application is provided with the display module 100 comprising the first soft glue part 40 and the hard glue part 50, which is beneficial to prolong the service life of the display module 100, and further beneficial to prolong the service life of the terminal 2000. In addition, when the terminal 2000 falls or is impacted, the corner part of the middle frame 700 is prone to deformation and extrusion of the display module 100, which is prone to damage of the display module 100. By arranging the clearance space 710 between the corner part of the middle frame 700 and the corner part of the display module 100, the deformed part of the middle frame 700 can be accommodated when the corner part of the middle frame 700 is deformed due to impact, so as to avoid the deformed part of the middle frame 700 extruding the display module 100 and causing damage of the display module 100, thereby further beneficial to prolong the service life of the terminal 2000.

[0098] In the embodiment, the clearance space 710 is formed between the inner side wall at the corner part of the middle frame 700 and the outer side wall at the corner part of the display mechanism 20, and the middle frame 700 is bonded with the side wall of the glass panel 10 and the side of the hard glue part 50 away from the metal part 225.

[0099] In the embodiment, the distance between the inner side wall at the corner part of the middle frame 700 and the outer side wall at the corner part of the display module 100 is 0.5mm-1mm (i.e. the width of the clearance space 710), which can ensure that the clearance space 710 has a proper size, so that the deformed part of the middle frame 700 can be effectively accommodated when the corner part of the middle frame 700 is deformed due to impact, and the deformed part of the middle frame 700 is avoided from extruding the display module 100 and causing damage of the display module 100, thereby beneficial to prolong the service life of the terminal 2000. In addition, the distance can also avoid that the size of the middle frame 700 is too large to affect the size and firmness of the combination of the middle frame 700 and the display module 100.
