Description

Technical Field

[0002] The display module includes a mid-frame and a display panel assembly. The display panel assembly includes a cover plate and a display panel attached to the cover plate. The cover plate is fixed to the top surface of the mid-frame or the top surface of a specially designed mounting groove using adhesive to ensure the bonding strength between the cover plate and the mid-frame. However, this also creates an adhesive gap between the cover plate and the mid-frame. On the other hand, to prevent the display panel from contacting the mid-frame and damaging it, a safety distance should be maintained between the display panel and the mid-frame. This safety distance and the adhesive gap constitute the bezel of the display module, limiting further increases in screen-to-body ratio. A display module with a narrow bezel and a large screen-to-body ratio can provide users with a better visual experience. Summary of the Invention

DETAILED DESCRIPTION

[0037] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, in which the same or similar components have the same reference numerals throughout the several views. The embodiments described below are exemplary and are intended to explain the present application, but are not to be understood as limiting the present application.

[0038] All directional indications, such as upper, lower, left, right, front, back, on the present application embodiments are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0039] The display module includes a middle frame and a display panel assembly, and the display panel assembly includes a cover plate and a display panel attached to the cover plate. The cover plate is fixed on the top surface of the middle frame or the top surface of a specially provided mounting groove by adhesive, and there is an adhesive width between the cover plate and the middle frame to ensure the bonding strength between the cover plate and the middle frame. On the other hand, in order to avoid the display panel from being damaged by contacting the middle frame, a safety distance should be reserved between the display panel and the middle frame. The safety distance and the adhesive width between the cover plate and the middle frame constitute the frame of the display module, which limits the further improvement of the screen-to-body ratio of the display module, and the display module with narrow frame and large screen-to-body ratio can provide good visual experience for users.

[0040] Reference Figure 1 and Figure 2 The display module 100 provided by the present application embodiment includes a middle frame 10 and a display panel assembly 20. The display panel assembly 20 can include a cover plate 21, a display panel 22, and a support 23. The display panel 22 is attached to the cover plate 21. The edge of the cover plate 21 is bonded to the side surface of the groove. The support 23 is located between the edge of the display panel 22 and the bottom surface of the groove, and the support 23 is bonded to the side surface and the bottom surface of the groove.

[0041] Specifically, the middle frame 10 can be a bezel structure arranged around the display panel assembly 20, and can be made of plastic or metal material. The middle frame 10 plays a role of supporting and protecting the display panel 22 in the display module 100, and ensures that the display panel assembly 20 remains stable and safe during installation and use.

[0042] The display panel 22 can be based on an organic light-emitting diode (OLED) display technology, and can convert an input electrical signal into a visible image or text for presentation on the cover plate 21 for a user to view.

[0043] The cover plate 21 is a surface covering layer of the display module 100, and can be made of transparent material (such as glass or plastic) to provide a flat surface for the display panel 22 to display. The middle frame 10 is formed with a recess, and the edges of the cover plate 21 are bonded to the side surfaces of the recess. The display panel 22 is attached to the cover plate 21, so that the cover plate 21 can seal the display panel 22 in the recess to prevent dust, moisture or other environmental factors from entering the inside of the recess, and protect the display panel 22 in the recess from the external environment, thereby prolonging the service life and stability of the display panel 22.

[0044] The support 23 can be located between the edges of the display panel 22 and the bottom surface of the recess, so that the display panel 22 is arranged between the cover plate 21 and the support 23, and plays a role of supporting and protecting the display panel 22. The bottom surface and the side surface of the recess can be provided with adhesive, and the support 23 can be bonded to the side surface and the bottom surface of the recess. The edges of the cover plate 21 can be bonded to the side surface of the recess through the adhesive. The contact width of the adhesive on the edges and the side surface of the cover plate 21 can be set as an effective bonding width a1. The support 23 can be bonded to the side surface of the recess through the adhesive, and the contact width of the adhesive on the support 23 and the side surface can be set as an effective bonding width a2. The support 23 can also be bonded to the bottom surface of the recess through the adhesive, and the contact width of the adhesive on the support 23 and the bottom surface can be set as an effective bonding width a3. The effective bonding width between the display assembly and the middle frame 10 can be set as A, A=a1+a2+a3.

[0045] In this way, the support 23 can be partially attached to the adhesive to ensure the effective bonding width, enhance the effective bonding width of the cover plate 21 and the middle frame 10, avoid the cover plate 21 from falling off, and improve the stability and reliability of the display module 100.

[0046] Reference Figure 3In related technologies, the cover plate 21 is fixed to the top surface of the middle frame 10 or the top surface of a specially designed mounting groove using adhesive. An additional distance needs to be provided on the top surface of the middle frame 10 to ensure an effective bonding width A between the cover plate 21 and the middle frame 10. The distance between the display panel 22 and the middle frame 10 can be set to B, and the distance between the edge of the display panel 22 and the cover plate 21 can be set to C, where C = A + B. Specifically, the effective bonding width A needs to be set greater than or equal to the effective bonding width threshold A0 to ensure the bonding strength between the cover plate 21 and the middle frame 10. The distance B between the display panel 22 and the middle frame 10 needs to be set greater than or equal to the safety distance B0 to prevent the display panel 22 from contacting the middle frame 10 and damaging the display panel 22. The distance C between the edge of the display panel 22 and the cover plate 21 needs to be set greater than or equal to A0 + B0.

[0047] In this embodiment, the cover plate 21 can be bonded to the side of the groove formed by the middle frame 10. The support member 23 located between the edge of the display panel 22 and the bottom surface of the groove can be bonded to the bottom and side surfaces of the groove formed by the middle frame 10 to ensure an effective bonding width A. No additional distance is required on the top surface of the middle frame 10, and the distance C between the edge of the display panel 22 and the cover plate 21 is equal to B. The distance C between the edge of the display panel 22 and the cover plate 21 needs to be greater than or equal to B0.

[0048] In the embodiment of this application, the distance C between the edge of the display panel 22 and the cover plate 21 in the display module 100 can reach a safe distance B0. The distance between the edge of the display panel 22 and the cover plate 21 can be set to be smaller, and the screen ratio of the display module 100 can be set to be larger, so that the display module 100 can provide users with a good visual experience.

[0049] The safety distance B0 can be determined based on the assembly precision of the display module 100. For example, if the bonding precision between the cover plate 21 and the display panel 22 is ±0.2mm, the edge bending precision of the display panel 22 is ±0.05mm, the assembly precision between the cover plate 21 and the middle frame 10 is ±0.1mm, the shape precision of the cover plate 21 is ±0.05mm, and the dimensional precision of the middle frame 10 is ±0.05mm, the safety distance B0 can be set to be greater than or equal to 0.3mm. The effective bonding width threshold A0 can be determined based on the assembly precision of the display module 100 and the material of the adhesive. The effective bonding width threshold A0 can be set to be greater than or equal to 0.4mm.

[0050] In some embodiments, the display panel assembly 20 further includes an optical adhesive and a polarizing layer 25.

[0051] Specifically, the optical adhesive layer 24 can be a transparent layer between the cover plate 21 and the display panel 22, and can be made of an optically clear adhesive (OCA).

[0052] The polarizing layer 25 can be located between the optical adhesive layer 24 and the display panel 22, and can be made of a polarizing sheet or other optical components.

[0053] Referring to Figure 4 In some embodiments, the support 23 includes a circuit board 231, and the display panel 22 is electrically connected to the circuit board 231.

[0054] Specifically, the circuit board 231 can include a rigid circuit board, and the display panel 22 is electrically connected to the rigid circuit board. Electronic devices on the rigid circuit board can drive or control the display panel 22 to work.

[0055] The rigid circuit board can support the display panel 22, so that the display panel 22 is arranged between the cover plate 21 and the support 23, and plays a supporting and protecting role for the display panel 22. The rigid circuit board can be reused as the support 23 of the display panel 22, which can save the position of the support 23 inside the recess, facilitate the assembly of the display module 100, and reduce the cost of the display module 100.

[0056] The circuit board 231 can be partially attached to the adhesive to ensure the effective bonding width and enhance the effective bonding width of the cover plate 21 and the middle frame 10. The top surface of the middle frame 10 does not need to be additionally provided with a certain distance, and the screen ratio of the display module 100 can be set larger.

[0057] In this way, the circuit board 231 can be reused as the support 23 of the display panel 22, which can improve the assembly efficiency of the display module 100 while ensuring the effective bonding width of the cover plate 21 and the middle frame 10.

[0058] Referring to Figure 4 In some embodiments, the middle frame 10 is formed with a receiving groove at the bottom surface of the recess, and the circuit board 231 is received in the receiving groove, and the circuit board 231 is bonded to the side surface and the bottom surface of the recess.

[0059] Specifically, the bottom surface of the receiving groove can be the bottom surface of the recess, and the side surface of the receiving groove can be the side surface of the recess or the side surface formed by the isolation piece. The placement position of the receiving groove can be determined according to the mounting position of the circuit board 231, and the size and shape of the receiving groove can be determined according to the size and shape of the circuit board 231. When assembling the display module 100, the circuit board 231 is mounted in the corresponding receiving groove, which improves the assembly efficiency of the display module 100.

[0060] Therefore, the middle frame 10 can be provided with a corresponding accommodating groove at the bottom surface of the groove to accommodate the circuit board 231, thereby improving the assembly efficiency of the display module 100.

[0061] With reference to Figure 2 and Figure 4 In some embodiments, the circuit board 231 is bonded to the bottom edge of the middle frame 10.

[0062] Specifically, the bottom edge of the cover plate 21 can be bonded to the groove side of the bottom edge of the middle frame 10 by adhesive. The adhesive can extend along the side of the groove to the bottom surface of the groove. The circuit board 231 can be installed in the accommodating groove below the bottom edge of the display panel 22, and the circuit board 231 can be attached to the adhesive of the groove side and the groove bottom surface, so that the circuit board 231 is bonded to the side and bottom surface of the groove.

[0063] The circuit board 231 is installed in the accommodating groove below the bottom edge of the display panel 22, which helps to optimize the layout of the wires on the circuit board 231, and makes the wires on the circuit board 231 more easily drawn from the bottom of the panel to connect to other electronic components or external interfaces, thereby simplifying wiring and maintenance. In addition, the heat generated by the electronic components on the circuit board 231 can also be dissipated through the bottom edge of the middle frame 10, which is beneficial to the heat dissipation of the circuit board 231.

[0064] Therefore, the circuit board 231 is bonded to the bottom edge of the middle frame 10, which helps to optimize the layout of the wires on the circuit board 231 and the heat dissipation of the circuit board 231.

[0065] With reference to Figure 2 and Figure 4 In some embodiments, the chip 26 is located between the bottom edge of the display panel 22 and the bottom surface of the groove, and the chip 26 is isolated from the circuit board 231.

[0066] Specifically, the chip 26 can be configured as a driving chip or a control chip of the display panel 22, and the chip 26 can drive the pixel circuit on the display panel 22 to control the working state and display content of the display panel 22.

[0067] Since the circuit board 231 is installed in the accommodating groove below the bottom edge of the display panel 22, the electronic components on the display panel 22 can also be arranged at the bottom edge of the display panel 22, so that the circuit board 231 is electrically connected to the display panel 22 through wires. The chip 26 can also be located between the bottom edge of the display panel 22 and the bottom surface of the groove, so that the chip 26 is electrically connected to the display panel 22 through wires.

[0068] The circuit board 231 is arranged separately from the chip 26, which can avoid mutual influence of the electrical signals output by the circuit board 231 and the chip 26 during the operation of the display panel 22, and improve the stability of the display panel 22. In addition, the separate arrangement of the circuit board 231 and the chip 26 can also avoid the pressing of the chip 26 by the circuit board 231, and improve the service life of the chip 26.

[0069] In this way, the circuit board 231 and the chip 26 can be arranged separately, while avoiding mutual influence of the electrical signals output by the circuit board 231 and the chip 26 and the pressing of the chip 26 by the circuit board 231, improving the service life of the chip 26 and the stability of the display panel 22.

[0070] Referring to Figure 4 In some embodiments, the circuit board 231 is formed with an open slot, the display panel assembly 20 includes a chip 26, and the chip 26 is arranged in the open slot.

[0071] Specifically, the circuit board 231 is formed with an open slot, and the inside of the open slot is hollow. The size and shape of the open slot can be set according to the size and shape of the chip 26, so as to ensure that the chip 26 can be arranged in the open slot, so as to realize the separate arrangement of the chip 26 and the circuit board 231, and avoid the pressing of the chip 26 by the circuit board 231.

[0072] In this way, the chip 26 can be arranged in the open slot to ensure the separate arrangement of the circuit board 231 and the chip 26.

[0073] Referring to Figure 2 and Figure 4 In some embodiments, the display panel 22 includes a display part 221, a curved part 222, and a non-display part 223. The display part 221 is connected to the non-display part 223 through the curved part 222. The curved part 222 is arranged in a curved manner. The display part 221 is attached to the cover plate 21, and the non-display part 223 is attached to the chip 26 and the circuit board 231.

[0074] Specifically, the display part 221 can be arranged on one side of the display panel 22, the non-display part 223 can be arranged on the other side of the display panel 22, and the curved part 222 can be arranged on the side between the display part 221 and the non-display part 223. The curved part 222 can act as an isolation area between the display part 221 and the non-display part 223, avoiding mutual interference of the electrical signals of the display part 221 and the electrical signals of the non-display part 223.

[0075] The curved part 222 is arranged in a curved manner, which can save the occupied space of the display panel 22, so that the display panel 22 can be more compactly assembled, thereby effectively utilizing the space of the entire display module 100.

[0076] The circuit board 231 and the chip 26 can be arranged with wires at the bending part 222, which is conducive to optimizing the wiring path of the wires, and shorter circuit paths can reduce the time delay of signal transmission and the possibility of electromagnetic interference, thereby helping to improve the performance and stability of the display panel 22.

[0077] In this way, the bending part 222 can be bent to save the occupied space of the display panel 22, thereby effectively utilizing the space of the entire display module 100. In addition, the circuit board 231 and the chip 26 can be arranged with wires at the bending part 222, which is conducive to improving the performance and stability of the display panel 22.

[0078] Referring to Figure 5 In some embodiments, the circuit board 231 includes a flexible circuit board 233 and a support plate 232, the flexible circuit board 233 is electrically connected with the display panel 22, and the support plate 232 is bonded with the side and bottom surfaces of the groove.

[0079] Specifically, the circuit board 231 can further include a flexible circuit board 233 and a support plate 232, the support plate 232 can be made of a metal material, and the flexible circuit board 233 can be made of a flexible material. The display panel 22 is electrically connected with the flexible circuit board 233, and the electronic devices on the flexible circuit board 233 can drive or control the display panel 22 to work.

[0080] The support plate 232 can be arranged in the accommodating groove, and the support plate 232 can support the display panel 22, so that the display panel 22 is arranged between the cover plate 21 and the support 23, and plays a supporting and protecting role for the display panel 22.

[0081] The flexible circuit board 233 can be arranged outside the accommodating groove, and the flexible circuit board 233 is arranged separately from the support plate 232 to avoid the support plate 232 pressing the flexible circuit board 233. The flexible circuit board 233 can also be attached to the display panel 22, thereby improving the bendability of the display panel 22.

[0082] In this way, the circuit board 231 can include a flexible circuit board 233 and a support plate 232, which can improve the bendability of the display panel 22 while playing a supporting and protecting role for the display panel 22.

[0083] Referring to Figure 6 In some embodiments, the support 23 includes a reinforcing plate 234, and the reinforcing plate 234 supports the display panel 22.

[0084] Specifically, the reinforcing plate 234 can adopt a Super Clean Foam (SCF) composite film. The SCF composite film, as a packaging material of the display module 100 in the assembly process, can effectively protect the key components inside the display panel 22 from dust, moisture and other pollutants in the external environment.

[0085] The SCF composite film can support the display panel 22, so that the display panel 22 is arranged between the cover plate 21 and the support 23, and plays a supporting and protecting role on the display panel 22. In order to improve the supporting strength of the reinforcing plate 234, the thickness of the copper foil in the SCF composite film can be increased, or stainless steel material can be used as the reinforcing plate 234.

[0086] In this way, the display panel 22 can be arranged between the cover plate 21 and the support 23, and plays a supporting and protecting role on the display panel 22.

[0087] Referring to Figure 2 and Figure 6 In some embodiments, the reinforcing plate 234 is bonded to the left and right edges and the top edge of the middle frame 10.

[0088] Specifically, the bottom edge of the cover plate 21 can be bonded to the groove side surface formed by the bottom edge of the middle frame 10 by the adhesive. The adhesive can extend along the side surface of the groove to the bottom surface of the groove. The reinforcing plate 234 can be expanded and fitted to the left and right edges and the top edge of the middle frame 10, and the reinforcing plate 234 can be fitted to the adhesive of the groove side surface and the groove bottom surface, so that the reinforcing plate 234 is bonded to the side surface and the bottom surface of the groove.

[0089] In this way, the reinforcing plate 234 can be fully fitted to the middle frame 10, improving the supporting strength of the reinforcing plate 234 and ensuring that the display panel assembly 20 remains stable and safe during installation and use.
