Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a screen module, a screen module assembly method, and an electronic device. Background Technology

[0002] Currently, screen modules are fixed using a combination of adhesive application and backing adhesive. The backing adhesive is applied to the edge of the screen glass to secure the screen module to the mid-frame. However, this fixing method results in a wider black border on the screen, affecting the user experience.

[0003] Therefore, using potting compound to fix the screen module and applying adhesive backing to the fixing compound optimizes the connection between the screen module and the mid-frame, reducing the width of the black border. However, the fixing compound can easily seep into the screen module through gaps, causing performance issues. Therefore, reducing the risk of fixing compound flowing into the screen module is a problem that needs to be solved. Summary of the Invention

[0028] Figure 1 And Figure 2 is a structural schematic diagram of the screen module of the embodiment, Figure 2 Only the light emitting surface 111, the light transmitting panel 12 and the shielding member 33 are shown in the figure, and the outline of the display panel 11 is shown by a dotted line, and the outline of the light transmitting panel 12 is shown by a double dotted line. Figure 3 is an exploded schematic diagram of the screen module of the embodiment.

[0029] In some embodiments, as Figures 1-3 shown, the screen module in the embodiment includes a display assembly 1, a protective shell 2 and a protective part 3. The protective shell 2 is used to protect the display assembly 1, and the protective part 3 is arranged at the edge position of the display assembly 1, which is used to protect the display assembly 1, and is used to fixedly connect the display panel 11 and the light transmitting panel 12.

[0030] Figure 4 is a schematic view of the display assembly 1 and the protective shell 2 of the present embodiment, only a partial area of the screen module is shown, and the outline of the protective shell 2 is shown by a thick dashed line. Figure 5 is a schematic view of the cross section of the screen module of the present embodiment in some embodiments. Figure 6 is a schematic view of the structure of the protective glue of the present embodiment. Figure 7 is a schematic view of the cross section of the screen module of the present embodiment in some other embodiments. Figures 5-7 shows Figure 1 the cross section direction shown in A-A.

[0031] In some embodiments, as shown in Figure 4 and Figure 5 , the protective shell 2 comprises a bending part 21. The bending part 21 is folded to form a receiving groove 22. The display assembly 1 comprises an optical connecting layer 13, a display panel 11 and a light-transmitting panel 12. The display panel 11 has an out-light surface 111 and a first side edge 112 located on one side of the out-light surface 111. Further referring to Figure 2 , the display panel 11 further has three second side edges 113 connected in sequence. The first side edge 112 is used to connect the display panel 11 with a control mainboard 17, so as to control the display panel 11 to generate images through the control mainboard 17. The light-transmitting panel 12 has an in-light surface 121. The out-light surface 111 is connected with the in-light surface 121 through the optical connecting layer 13. The optical connecting layer 13 is used to connect the out-light surface 111 and the in-light surface 121 together. The light generated by the display panel 11 is emitted to the in-light surface 121 through the out-light surface 111, and then displayed through the light-transmitting panel 12.

[0032] Further referring to Figure 5 , the first side edge 112 is located in the receiving groove 22, that is, the first side edge 112 is inserted into the receiving groove 22, so as to protect the first side edge 112 through the receiving groove 22. The optical connecting layer 13 described above separates the first side edge 112 from the light-transmitting panel 12, so that a gap is formed between the first side edge 112 and the edge of the light-transmitting panel 12. The edge of the bending part 21 extends into the gap between the first side edge 112 and the light-transmitting panel 12, and the edge of the bending part 21 and the opposite side of the light-transmitting panel 12 form a first gap 41 towards the lateral side of the light-transmitting panel 12. Further referring to Figure 3 , the protective part 3 comprises a shielding piece 33, a first glue 31 and a second glue 32. The materials of the first glue 31 and the second glue 32 can be configured to be the same or different, and the first glue 31 can be glue or adhesive tape. The shielding piece 33 can be a metal piece or a plastic piece.

[0033] Optionally, as shown in Figure 5As shown, the light-transmitting panel 12 includes a glass cover plate for conducting the light entering the light-in surface 121 to the side away from the display panel 11. The optical connecting layer 13 includes but is not limited to an adhesive film 131 and a polarizer 132. The polarizer 132 is used to change the polarization direction of the light. One side of the polarizer 132 is arranged on the light-out surface 111, and the other side is bonded to the light-in surface 121 of the glass cover plate through the adhesive film 131. The adhesive film 131 has good light transmission. The adhesive film 131 can be in the form of a solid optical adhesive film (Optically Clear Adhesive) or a liquid optical adhesive (Optically Clear Resin).

[0034] Specifically, the edge thickness of the bending portion 21 is less than the thickness of the optical connecting layer 13, so that the edge area of the bending portion 21 and the edge area of one side of the light-transmitting panel 12 form the first gap 41. The first gap 41 has an opening through which the side of the optical connecting layer 13 faces the side of the screen module.

[0035] Further referring to Figure 2 and Figure 6 As shown, the second adhesive 32 includes a cladding block 321, the shielding piece 33 is fixedly connected to the protective shell 2 and the display assembly 1 through the first adhesive 31, and the shielding piece 33 shields the first gap 41 along the length direction of the first side edge 112, and the cladding block 321 extends along the length direction of the first side edge 112 and clads the shielding piece 33 and at least part of the bending portion 21.

[0036] In summary, the screen module in the embodiment uses the protective shell 2 to protect the first side edge 112 of the display panel 11, so as to facilitate the display panel 11 to set the connector through the first side edge 112. At the same time, the optical connecting layer 13 connects the light-out surface 111 and the light-in surface 121 together, so that the light generated by the display panel 11 can enter the light-transmitting panel 12 through the optical connecting layer 13. In this form, the optical connecting layer 13 separates the display panel 11 from the light-transmitting panel 12, resulting in the first gap 41 between the bending portion 21 and the light-transmitting panel 12. Therefore, the shielding piece 33 is fixedly connected to the protective shell 2 and the display assembly 1 through the first adhesive 31, so that the shielding piece 33 shields the first gap 41. When the cladding block 321 is formed by the glue pouring method, the second adhesive 32 can be prevented from entering the first gap 41, thereby reducing the situation that the second adhesive 32 enters the accommodating groove 22. At the same time, it can also avoid that the second adhesive 32 generates stress between the bending portion 21 and the light-transmitting panel 12 after solidification. On the other hand, the shielding piece 33 can reduce the manufacturing cost of the screen module. At the same time, it effectively improves the structural strength of the screen module at the position of the first side edge 112.

[0037] In some embodiments, as Figures 5-6As shown, the protective shell 2 comprises a guard plate 23 connected with the bending part 21, and the guard plate 23 covers the side of the display panel 11 away from the light-transmitting panel 12. The shielding piece 33 covers the edge of the guard plate 23 and at least part of the bending part 21. The shape of the shielding piece 33 in the embodiment can be adjusted according to the protective shell 2, thereby reducing the gap between the shielding piece 33 and the protective shell 2.

[0038] In some embodiments, as shown in Figures 4-5 As shown, the bending part 21 comprises a first folding edge 211 and a second folding edge 212 extending along the length direction of the first side edge 112. The first folding edge 211 is arranged opposite to the guard plate 23, and the first folding edge 211 forms a first gap 41 with the light-transmitting panel 12. One side of the second folding edge 212 is connected with the guard plate 23, and the other side is connected with the first folding edge 211. The guard plate 23, the second folding edge 212 and the first folding edge 211 form the accommodating groove 22. Further referring to Figure 6 As shown, the shielding piece 33 comprises a first blocking strip 331, a second blocking strip 332 and a third blocking strip 333 extending along the length direction of the first side edge 112. The first blocking strip 331 is bonded to the edge of the guard plate 23 through the first adhesive 31. The third blocking strip 333 is bonded to the light-incident surface 121 through the first adhesive 31. The second blocking strip 332 is connected between the first blocking strip 331 and the third blocking strip 333.

[0039] Specifically, the first blocking strip 331 is arranged on the guard plate 23, and the third blocking strip 333 is arranged on the light-transmitting panel 12. A first portion of the first adhesive 31 is arranged along the length direction of the first blocking strip 331, and a second portion of the first adhesive 31 is arranged along the length direction of the third blocking strip 333. In this way, the second adhesive 32 is prevented from flowing into the accommodating groove 22 from the gap between the first blocking strip 331 and the guard plate 23 and the gap between the third blocking strip 333 and the light-transmitting panel 12.

[0040] In some embodiments, as shown in Figure 5 and Figure 6 As shown, the second blocking strip 332 extends parallel to and abuts against the second folding edge 212. The first blocking strip 331 is bent away from the bending part 21, i.e., the first blocking strip 331 is bent towards the guard plate 23. The first folding edge 211 is opposite to the bending direction of the first blocking strip 331, i.e., the first folding edge 211 is on the same side of the second folding edge 212 as the guard plate 23. In this way, the second blocking strip 332 and the second folding edge 212 are used to limit the position of the shielding piece 33, thereby ensuring the positional accuracy between the shielding piece 33 and the display assembly 1. Meanwhile, the gap between the shielding piece 33 and the protective shell 2 is reduced. In addition, in the embodiment, the second folding edge 212 cooperates with the second blocking strip 332 to increase the rigidity of the first side edge 112 in the height direction of the second folding edge 212 (as shown by the arrow in Figure 6 ), thereby preventing the screen module from being squeezed after being assembled with the middle frame.

[0041] Figure 8 and Figure 9 is a process flow diagram of the screen module of the present embodiment.

[0042] In some embodiments, as shown in Figure 2 , Figure 5 , Figure 6 and Figure 8 , the third blocking strip 333 has a plurality of filling through holes 334. The first adhesive 31 is a solidified adhesive, which is filled in the filling through holes 334 and between the third blocking strip 333 and the light-in surface 121. In this way, the sealing between the third blocking strip 333 and the light-transmitting panel 12 is improved.

[0043] Preferably, the filling through holes 334 are tapered holes, the small-diameter opening of which faces the light-transmitting panel 12, and the large-diameter opening of which faces the back adhesive 6. When the first adhesive 31 in the filling through holes 334 is solidified, the fixing strength of the blocking member 33 and the light-transmitting panel 12 can be improved. The large-diameter and small-diameter openings can be circular or elliptical. The first blocking strip 331 and the guard plate 23 can also be connected by using the solidified adhesive.

[0044] Specifically, the thickness of the blocking member 33 (the thickness of the third blocking strip 333) is 0.1-0.2 mm, and the diameter of the small-diameter opening of the filling through hole 334 is greater than 0.25 mm.

[0045] Figure 10 is an enlarged schematic view of the display assembly 1, the protective shell 2 and the first adhesive 31 in region C in Figure 4 , in which the outline of the protective shell 2 and the first part is shown by a thick solid line, and the outline of the second part is shown by a thick dashed line. Figure 11 is an enlarged schematic view of the display assembly 1, the protective shell 2, the first adhesive 31 and the blocking member 33 in region C in Figure 4 , in which the outline of the protective shell 2 is shown by a thick solid line, the outline of the blocking member 33 is shown by a thick dashed line, and the outline of the first adhesive 31 is shown by a thin solid line. Figure 12 is an enlarged schematic view of region B in Figure 3 .

[0046] In some embodiments, as shown in Figure 8 and Figure 9 , the cross section of the blocking member 33 in the extending direction is a profile Z-shaped structure, so that the blocking member 33 is more fitted with the display assembly 1 and the protective shell 2, which helps the second adhesive 32 to be injected through the injection port by the forming mold 5. Further referring to Figure 10 , when the side of the display panel 11 away from the light-out surface 111 is exposed outside the guard plate 23 (as shown in region I in Figure 10 ), a third gap 43 is formed between the guard plate 23 and the display panel 11. Further referring to Figure 11As shown, the first blocking strip 331 can also prevent the second adhesive 32 from entering the accommodating groove 22 from the third gap 43.

[0047] In some embodiments, as shown in Figure 11 As shown, in the length direction of the first side edge 112, the two ends of the second folding edge 212 form two second gaps 42 with the first side edge 112, and the second gaps 42 are directed towards the light-transmitting panel 12. The two ends of the second blocking strip 332 are bent and extend to cover the two second gaps 42, respectively. The second gaps 42 are perpendicular to the first gap 41.

[0048] Specifically, in the present embodiment, the two ends of the second folding edge 212 extend to the two ends of the first side edge 112, and the first blocking strip 331, the second blocking strip 332, and the third blocking strip 333 are all bent and arranged along the corner positions of the display panel 11. In this way, the second adhesive 32 is prevented from entering the accommodating groove 22 from the two ends of the second folding edge 212.

[0049] In some embodiments, as shown in Figure 5 、 Figure 11 and Figure 12 As shown, the display panel 11 includes a backlight layer 14, a mounting frame 15, a connecting line 16, and a control mainboard 17. The mounting frame 15 has an accommodating area 152 and a connecting window 151, at least part of the backlight layer 14 is arranged in the accommodating area 152, the mounting frame 15 is located between the light-transmitting panel 12 and the control mainboard 17, the backboard 23 is arranged on the control mainboard 17, one end of the connecting line 16 is electrically connected with the backlight layer 14 on one side of the first side edge 112, and the other end of the connecting line 16 passes through the connecting window 151 and is connected with the control mainboard 17, and the connecting window 151 is located between the two second gaps 42.

[0050] Specifically, the mounting frame 15 is a plate structure, and the plate structure includes a first plate edge, and the first plate edge is bent to form the accommodating area 152. The accommodating area 152 is away from the light-transmitting panel 12 and is close to the side of the second folding edge 212, and the connecting window 151 is arranged on the side of the second folding edge 212. The backlight layer 14 includes a light guide plate and a plurality of lamp strips, and the plurality of lamp strips are arranged on the side of the light guide plate close to the connecting window 151. The connecting line 16 is a flexible circuit board. One end of the flexible circuit board is connected with the backlight layer 14 to supply power to the plurality of lamp strips, and the other end of the flexible circuit board passes through the connecting window 151 along the inner wall of the mounting frame 15, and then extends to the control mainboard 17 along the outer wall of the mounting frame 15. The control mainboard 17 is also used to be connected with other devices of the electronic device. The display panel 11 further includes a color filter 18, one side of the color filter 18 is abutted with the outer surface of the first plate edge, and the other side of the color filter 18 is abutted with the first folding edge 211.

[0051] In the embodiment, the connecting window 151 is arranged in the accommodating groove 22, and the first gap 41, the second gap 42 and the third gap 43 are blocked by the first adhesive 31, so that the second adhesive 32 cannot enter the accommodating area 152 through the accommodating groove 22, and the second adhesive 32 is prevented from contacting the backlight layer 14 and the connecting line 16.

[0052] In some embodiments, as shown in FIG. 1, the first adhesive 31 and the second adhesive 32 are configured to have different flowabilities before curing. Figures 8-9 In some embodiments, as shown in FIG. 1, the first adhesive 31 and the second adhesive 32 are configured to have different viscosities before curing.

[0053] It is easy to understand that the first adhesive 31 has a smaller flowability in the embodiment, and after the first adhesive 31 is extruded from the glue head 71, the first adhesive 31 is not easily scattered, so that the operator can bond the shielding piece 33 on the top of the first adhesive 31, and the first adhesive 31 is cured in time by the curing lamp 72. In contrast, the second adhesive 32 has a larger flowability, so that the second adhesive 32 can be filled into the gaps of the display assembly 1, the protective shell 2 and the first adhesive 31 during the glue pouring.

[0054] Optionally, the first adhesive 31 can be ultraviolet light curing adhesive (Ultraviolet Light Curing Adhesive). The curing lamp 72 is an ultraviolet curing lamp 72. The second adhesive 32 can be GOM glue. The components thereof include, but are not limited to, organic silicon, epoxy glue and adhesive and the like.

[0055] In some embodiments, as shown in FIG. 1, the first adhesive 31 and the second adhesive 32 are configured to have different viscosities before curing. Figures 8-9 In some embodiments, as shown in FIG. 1, the first adhesive 31 and the second adhesive 32 are configured to have different viscosities before curing.

[0056] Further, the viscosity of the first adhesive 31 is 3.8-50 mPa·s, and the viscosity of the second adhesive 32 is 1.1-2 mPa·s. In the embodiment, the viscosities of the first adhesive 31 and the second adhesive 32 are configured within a certain range, so that the protective shell 3 is formed by the dispensing and the glue pouring respectively.

[0057] In an alternative implementation, the screen module in the above embodiments can be applied to an electronic device. This electronic device includes, but is not limited to, devices such as mobile phones or laptops. The electronic device also includes a mid-frame. Further referring to... Figure 5 and Figure 6 As shown, the top of the covering block 321 is provided with adhesive 6. This adhesive 6 is used to bond to the mid-frame, thus assembling the screen module and the mid-frame. In this form, as... Figure 6 The distance L1 is the width of the black border area of ​​the screen module. In this embodiment, the distance L1 can be controlled to be around 0.75mm.

[0058] In other implementations, such as Figure 7 As shown, the adhesive 6 is directly applied to the edge of the light-transmitting panel 12. Compared to the way the adhesive 6 is applied in the above embodiment, the black border of the screen module in this embodiment is wider (distance L2 is greater than distance L1). When the electronic device is a tablet computer, the range of L2 is 7mm-11mm, and when the electronic device is a mobile phone, the range of L2 is 3.5mm-4.5mm.

[0059] In summary, the electronic device in this embodiment uses a protective shell 2 to protect the first side 112 of the display panel 11, so that the display panel 11 can be equipped with connecting devices through the first side 112. Simultaneously, an optical connecting layer 13 connects the light-emitting surface 111 and the light-receiving surface 121 together, allowing light generated by the display panel 11 to pass through the optical connecting layer 13 and enter the light-transmitting panel 12. In this configuration, the optical connecting layer 13 separates the display panel 11 from the light-transmitting panel 12, resulting in a first gap 41 between the bent portion 21 and the light-transmitting panel 12. Therefore, the shielding member 33 is fixedly connected to the protective shell 2 and the display assembly 1 via the first adhesive 31, so that the shielding member 33 blocks the first gap 41. When the encapsulating block 321 is formed by potting adhesive, the second adhesive 32 can be prevented from entering the first gap 41, thereby reducing the occurrence of the second adhesive 32 entering the receiving groove 22. Simultaneously, it also prevents stress from being generated between the bent portion 21 and the light-transmitting panel 12 after the second adhesive 32 has cured. On the other hand, the use of the shielding component 33 can reduce the manufacturing cost of the screen module. At the same time, it effectively improves the structural strength of the screen module at the first side 112 position.

[0060] Figure 13 This is a flowchart illustrating the screen module assembly method of this embodiment.

[0061] like Figure 13 As shown, in an optional implementation, the screen module in the above embodiments can be assembled in the following manner.

[0062] Step S100: disposing the first glue 31 along the length direction of the first side edge 112 on the light-in surface 121 and the protective shell 2.

[0063] Preferably, the first glue 31 is glue. The first part is coated on the top edge of the guard plate 23, and the second part is coated at the opening of the first gap 41.

[0064] Step S200: bonding the shielding piece 33 to the first glue 31 to shield the first gap 41. In this step, the shielding piece 33 is arranged on the display assembly 1 and the protective shell 2 from top to bottom.

[0065] Optionally, the curing lamp 72 cures the first glue 31 to seal the gap between the shielding piece 33 and the display assembly 1 and the protective shell 2.

[0066] Preferably, the caliber of the glue head 71 is configured to be 0.2mm-0.25mm, and the glue outlet of the glue head 71 is obliquely arranged and maintains a small gap with the light-in surface 121, so that the adhesive layer 312 is more flat after the first glue 31 is extruded. The thickness of the plurality of adhesive layers 312 is controlled to be 0.1mm-0.2mm, and the width is controlled to be greater than or equal to 0.25mm.

[0067] Step S300: disposing the forming mold 5 on the first side edge 112. Wherein the bending part 21 and the shielding piece 33 are located in the cavity 51 of the forming mold 5.

[0068] Step S400: injecting the second glue 32 into the cavity 51 to wrap the shielding piece 33 and at least part of the bending part 21 with the second glue 32.

[0069] Step S500: disassembling the forming mold 5.

[0070] After step S500, the back glue 6 is disposed on the side of the wrapping block 321 away from the light-transmitting panel 12.

[0071] In summary, in the screen module assembly method in the embodiment, the shielding piece 33 is fixedly connected with the protective shell 2 and the display assembly 1 through the first glue 31, so that the shielding piece 33 shields the first gap 41. When the wrapping block 321 is formed by the glue injection method, the second glue 32 can be prevented from entering the first gap 41, thereby reducing the situation that the second glue 32 enters the accommodating groove 22. At the same time, the stress between the bending part 21 and the light-transmitting panel 12 after the second glue 32 is cured can also be avoided. On the other hand, the shielding piece 33 can reduce the manufacturing cost of the screen module. At the same time, the structural strength of the screen module at the position of the first side edge 112 is effectively improved.

[0072] Further, the step S100 specifically includes: coating the first glue 31 on the light-in surface 121 along the length direction of the first side edge 112. The third blocking strip 333 covers the first glue 31 on the light-in surface 121. The first glue 31 is coated to the filling through hole 334, so that the first glue 31 of the filling through hole 334 is adhered between the third blocking strip 333 and the first glue 31 of the light-in surface 121. The first glue 31 is solidified. Meanwhile, the first glue 31 between the first blocking strip 331 and the protective shell 2 is also solidified. Thus, the connection strength of the shielding piece 33 and the display assembly 1 and the protective shell 2 is ensured.

[0073] In another optional implementation, the screen module in the above embodiment can be assembled in the following manner. The middle region of the shielding piece 33 extends in a straight line and the two ends are bent to be arranged, so that the shielding piece 33 can shield the first gap 41 and the two second gaps 42 located at the corner positions of the display panel 11. The display panel 11 has a first side edge 112 and three second side edges 113.

[0074] The step S300 specifically includes: arranging the forming mold 5 at the positions of the first side edge 112 and the three second side edges 113. That is, the first side edge 112 and the three second side edges 113 are simultaneously coated with glue. The second glue 32 is arranged around the edge positions of the light-in surface 121, so that the fixing effect of the second glue 32 is increased.

[0075] Optionally, the three second side edges 113 are not provided with the first glue 31 and the shielding piece 33, so that the height and the width of the cladding block 321 corresponding to the three second side edges 113 are smaller than those of the cladding block 321 corresponding to the first side edge 112. Thus, the amount of the second glue 32 is reduced.

[0076] In yet another optional implementation, as shown in Figure 2 and Figure 3 , the screen module in the above embodiment can be assembled in the following manner. The display panel 11 has a first side edge 112 and three second side edges 113. The protective shell 2 further includes three protective covers 24. The three protective covers 24 respectively cover the three second side edges 113 (as Figure 4 and Figure 10The shielding piece 33 is annular, and in the extending direction of the shielding piece 33, the shielding piece 33 comprises four straight extending sections and four curved sections, the straight extending sections are connected by the curved sections, and each straight extending section and each curved section comprises a first blocking strip 331, a second blocking strip 332 and a third blocking strip 333. The first blocking strip 331 is covered on the top edge of the display panel 11 and the protective shell 2 by the first adhesive 31. In this form, the first blocking strip 331 can also shield the gap between the protective cover 24 and the second side edge 113 to prevent the second adhesive 32 from entering. The forming mold 5 is arranged at the first side edge 112 and the three second side edges 113. That is, the first side edge 112 and the three second side edges 113 are filled with adhesive at the same time. The second adhesive 32 is wrapped around the edge position of the light entrance surface 121 and covers the shielding piece 33. Thus, the protective effect of the protective adhesive 3 on the screen module is further improved.

[0077] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
