[0049] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.
[0050] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the invention disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the following claims.
[0051] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
[0052] The present disclosure provides a display module. Figure 1 This is a schematic diagram of the structure of a display module provided by an embodiment of the present disclosure. Figure 1 As shown, the display module includes:
[0053] Display screen 10;
[0054] A flexible circuit board 20 is electrically connected to the edge of the display screen 10 and is used to drive the display screen 10 to display;
[0055] The colloid 30 wraps the flexible circuit board 20 and fixes the display screen and the flexible circuit board.
[0056] The display screen is used to display images and colors.
[0057] Specifically, the display screen may be a liquid crystal display (LCD) or an organic light emitting diode (OLED) display screen.
[0058] In the embodiment of the present disclosure, the flexible circuit board and the display screen are electrically connected in a form of connecting the flexible circuit board and the display screen via a physical line such as a wire that can transmit an electrical signal.
[0059] The flexible circuit board can be a highly reliable and flexible printed circuit. By embedding circuit designs on a thin, flexible plastic sheet, a large number of precision components can be packed into a narrow and confined space, thus forming a flexible circuit. This circuit can be bent and folded at will, and is lightweight, compact, has excellent heat dissipation, and is easy to install. In the disclosed embodiment, the flexible circuit board is electrically connected to the edge of a display screen, and the various circuit components on the flexible circuit board can drive the display screen to display images.
[0060] For example, the flexible circuit board may include but is not limited to: Chip On Flex (or Chip On Film, COF).
[0061] The colloid has a certain strength and reliability, and is used to protect the flexible circuit board and support the display screen and the flexible circuit board. Exemplarily, the colloid can be any colloid with a certain supporting force. Exemplarily, the colloid can include but is not limited to structural adhesive. The flexible circuit board is small in size and light in weight. The part not connected to the display screen is relatively weak and easily damaged by collisions. In addition, during the transportation, assembly and / or use of the display module, the flexible circuit board may bend to varying degrees due to its own characteristics, thereby causing collisions with other components in the display module, causing damage or even destruction of the circuit elements in the flexible circuit board, thereby affecting the display of the display screen. Therefore, in the embodiment of the present disclosure, by providing the colloid, it is possible to reduce the damage to the flexible circuit board during transportation, assembly and / or use. At the same time, the colloid can support and fix the flexible circuit board and the display screen, thereby reducing the width of the frame supporting the display screen, or eliminating the need for the frame to support the display screen, thereby reducing the black border area caused by the space required for the display screen and the frame to avoid the flexible circuit board, thereby improving the screen ratio of the display screen and further reducing the black border of the display screen.
[0062] In the embodiment of the present disclosure, by providing a colloid wrapping the flexible circuit board, the flexible circuit board can be protected, so that the display screen connected to the flexible circuit board can work normally.
[0063] In some embodiments, the colloid is a hard glue after curing.
[0064] In the embodiment of the present disclosure, by setting the colloid to be a cured hard glue, the high strength and high reliability of the hard glue can be used to ensure the strength of the colloid, thereby improving the protection effect of the flexible circuit board.
[0065] In some embodiments, the display screen is mounted in a receiving cavity formed by the frame;
[0066] The colloid is in contact with the side wall of the frame or is spaced apart from the side wall.
[0067] The frame has four side surfaces and a bottom surface, forming the housing cavity. The display screen is mounted within the housing cavity, with one side of the display screen corresponding to a side of the frame. Each side of the frame is provided with a colloid to protect the flexible printed circuit board from collision or compression by the frame. The display screen can also be displayed through the upper opening of the housing cavity, allowing it to properly display information such as application interfaces or video data.
[0068] The frame can be a plastic frame and / or a metal frame coated with an insulating layer, etc. The frame can be an inner frame or outer frame of an electronic device, etc., and can be a component structure other than a display module.
[0069] In the disclosed embodiments, the colloid wrapping prevents direct contact between the flexible circuit board and the frame. Therefore, even if the colloid were placed in contact with the sidewalls of the frame, it would not affect the flexible circuit board. Therefore, the colloid wrapping can reduce the distance between the flexible circuit board and the frame, thereby shortening the distance between the display screen and the sidewalls of the frame, thereby increasing the screen-to-body ratio of the display screen within the housing.
[0070] In some embodiments, the bottom surface of the frame is provided with a glue point, and the glue point bonds the glue point to the bottom surface of the frame;
[0071] and / or,
[0072] A glue point is provided on the side surface of the frame body, and the glue point is used to bond the colloid to the side surface of the frame body.
[0073] In the embodiment of the present disclosure, the bottom surface and / or side surface of the frame may be provided with adhesive for bonding the colloid to the bottom surface of the frame, or bonding the colloid to the side surface of the frame.
[0074] In the embodiment of the present disclosure, the colloid is bonded to the frame by setting a glue spot, which is simple to operate, and the glue spot is only set on the side and / or bottom of the frame, which is convenient for separating the frame and the colloid during subsequent disassembly, thereby facilitating inspection and / or maintenance of the display module.
[0075] In some embodiments, the display screen is no longer mounted on top of the frame, but is instead flush with the top of the frame's sidewalls, with the screen supported solely by the colloid. This way, once the frame's sidewalls meet strength requirements, there's no need for an additional platform for the display screen, allowing the frame's thickness to be reduced, further reducing the width of the display module's overall black border area.
[0076] In some embodiments, the display module further includes:
[0077] The bracket is arranged in the accommodating cavity and is fixed to the bottom surface of the display screen and / or to the colloid.
[0078] The bottom surface of the display screen is the opposite side of the display surface of the display screen. For example, the bracket can be fixed to the bottom surface of the display screen by bonding or other methods.
[0079] In the disclosed embodiment, the bracket is secured to the bottom surface of the display screen, providing support and protection for the display screen. Furthermore, the bracket supports the display screen, eliminating the need for an additional platform within the frame to support the display screen. This further reduces the thickness of the frame and the width of the black border area of the display module.
[0080] In the embodiment of the present disclosure, by fixing the bracket and the colloid, the assembly of the display module is facilitated and the stability of the display module is further improved.
[0081] In the disclosed embodiment, the gap between the bracket, the flexible circuit board and the display screen may be wrapped with colloid and solidified, thereby integrating the bracket, the flexible circuit board and the display screen, facilitating the transportation and assembly of the display module.
[0082] In some embodiments, the bracket can be fixed in the accommodating cavity, and there are various specific fixing methods. For example, the bracket can be fixed in the accommodating cavity by screws, pins and / or nuts.
[0083] In some embodiments, the bracket may be a plastic frame.
[0084] The height of the bracket in the direction away from the back of the display screen can be slightly lower than the height of the frame, so that a step-like height difference is formed between the bracket and the frame. The display screen is mounted on the top surface of the bracket, and the side edge of the display screen rests on the side edge of the frame, further reducing the visual effect of the border of the display module.
[0085] In some embodiments, the bracket includes a support column and a base, the support column is fixed to the base, and the support column is fixed to the bottom surface of the display screen and / or to the colloid;
[0086] One side of the base is fixed to the colloid, and the other side is fixed to the bottom surface of the frame.
[0087] In the disclosed embodiment, the bracket may include a support column and a base. The support column is fixed to the base to support and secure the display screen. One side of the base is fixed to the colloid, and the other side is fixed to the bottom surface of the frame to enhance the stability of the bracket. For example, the bracket may be an L-shaped bracket. The support column may be positioned at the edge of the display screen near the frame. While providing support, it can also separate the flexible printed circuit board from the frame, thereby protecting the flexible printed circuit board.
[0088] In the disclosed embodiment, the other surface of the base fixed to the bottom surface of the frame can be the opposite surface of the surface of the base fixed to the colloid. For example, the first surface of the base of the bracket is fixed to the colloid, and the second surface is fixed to the bottom surface of the frame. The first surface and the second surface are two opposite surfaces on the base.
[0089] In some embodiments, the support pillars may be fixed to the colloid, thereby further improving the overall stability of the display module.
[0090] In some embodiments, the top of the support column is fixed to the bottom of the display screen through the colloid.
[0091] In the disclosed embodiment, the support column and the display screen are fixed by colloid, which can improve the bonding strength between the support column and the display screen and further improve the stability of the display module.
[0092] In some embodiments, the base is provided with a glue injection hole for injecting the colloid before curing.
[0093] In the disclosed embodiment, a glue injection hole is provided in the base of the bracket, through which a colloid to be cured can be injected. After the colloid cures, the bracket, colloid, flexible circuit board, and display screen are integrated, increasing the stability of the display module while facilitating its transportation and assembly.
[0094] In some embodiments, the bracket is bonded to the bottom surface of the frame;
[0095] and / or,
[0096] The bracket is bonded to the side surface of the frame.
[0097] In the embodiment of the present disclosure, by setting the bracket in the accommodating cavity and bonding the bracket to the frame, the bracket, colloid, frame, flexible circuit board and display screen are integrated, so that the display screen and the flexible circuit board are more stable, the protection effect is better, and the transportation and assembly of the display module are facilitated.
[0098] In some embodiments, a glue injection hole is provided on the bottom or side surface of the frame; wherein the glue injection hole is used to inject the glue before curing.
[0099] In the disclosed embodiment, a glue injection hole is provided on the frame, through which a glue to be cured can be injected. After the glue is cured, the frame, glue, flexible circuit board, and display screen are integrated, which increases the stability of the display module and facilitates its transportation and assembly.
[0100] The present disclosure provides a method for installing a display module. Figure 2A flow chart of a method for installing a display module provided in an embodiment of the present disclosure. Figure 2 As shown, the installation method of the display module includes:
[0101] Step 110: Establishing electrical connections between the edges of the flexible circuit board and the display screen;
[0102] Step 120: forming a colloid that wraps the flexible circuit board, and the colloid adheres the display screen and the flexible circuit board.
[0103] In the embodiment of the present disclosure, an electrical connection may be established at the edge of the flexible circuit board and the display screen by connecting through a physical line such as a wire that can transmit an electrical signal.
[0104] The display screen is used to display images and colors. Specifically, the display screen can be a liquid crystal display (LCD) or an organic light emitting diode (OLED) display screen.
[0105] The flexible circuit board can be a highly reliable and flexible printed circuit. By embedding circuit designs on a thin, flexible plastic sheet, a large number of precision components can be packed into a narrow and confined space, thus forming a flexible circuit. This circuit can be bent and folded at will, and is lightweight, compact, has excellent heat dissipation, and is easy to install. In the disclosed embodiment, the flexible circuit board is electrically connected to the edge of a display screen, and the various circuit components on the flexible circuit board can drive the display screen to display images.
[0106] The colloid has a certain strength and reliability, and is used to protect the flexible circuit board and support the display screen and the flexible circuit board. Exemplarily, the colloid can be any colloid with a certain supporting force. Exemplarily, the colloid can include but is not limited to structural adhesive. The flexible circuit board is small in size and light in weight. The part not connected to the display screen is relatively weak and easily damaged by collisions. In addition, during the transportation, assembly and / or use of the display module, the flexible circuit board may bend to varying degrees due to its own characteristics, thereby causing collisions with other components in the display module, causing damage or even destruction of the circuit elements in the flexible circuit board, thereby affecting the display of the display screen. Therefore, in the embodiment of the present disclosure, by providing a colloid layer, it is possible to reduce the damage to the flexible circuit board during transportation, assembly and / or use. At the same time, the colloid can support and fix the flexible circuit board and the display screen, thereby reducing the width of the frame supporting the display screen, or eliminating the need for the frame to support the display screen, thereby reducing the black border area caused by the space required for the display screen and the frame to avoid the flexible circuit board, thereby improving the screen ratio of the display screen and further reducing the black border of the display screen.
[0107] In the disclosed embodiment, the size of the colloid can be adjusted based on the size of the portion of the flexible circuit board not connected to the display, ensuring that the colloid's size and strength are sufficient to support the display. This allows the colloid to be wrapped only on the portion of the flexible circuit board that requires protection, providing targeted protection and reducing the cost of the wrapping process.
[0108] In the embodiment of the present disclosure, by wrapping the colloid on the flexible circuit board, the flexible circuit board can be protected, so that the display screen connected to the flexible circuit board can work normally.
[0109] In some embodiments, forming a colloid that wraps the flexible circuit board, and bonding the display screen and the flexible circuit board with the colloid, includes:
[0110] bending the flexible circuit board;
[0111] A colloid is formed to wrap the bent flexible circuit board.
[0112] In the disclosed embodiment, the bendability of the flexible circuit board can be utilized to bend the flexible circuit board and then form a colloid that wraps the flexible circuit board. This can further reduce the space occupied by the flexible circuit board, thereby reducing the space occupied by the entire display module and improving the applicability of the display module.
[0113] In some embodiments, the method further comprises:
[0114] After the flexible circuit board is electrically connected to the edge of the display screen, a fluid colloid is injected through the glue injection hole on the frame;
[0115] The colloid is obtained by solidification.
[0116] In the embodiment of the present disclosure, by injecting a fluid colloid into the glue filling hole on the frame, wrapping the flexible circuit board and solidifying the colloid, the display screen, the flexible circuit board and the colloid can be integrated, so that the display screen and the flexible circuit board are completely fitted together and will not fall off, thereby reducing the occurrence of poor contact and improving safety of use.
[0117] In the embodiment of the present disclosure, the frame can be heated to a preset temperature to accelerate the curing of the colloid. Specifically, the preset temperature should be lower than the tolerable temperature of the display module to reduce possible damage to the display module caused by the temperature.
[0118] By wrapping the flexible circuit board with colloid, the entry of dust and / or water and other substances that may affect the normal operation of the display module can be reduced, thereby improving the reliability of the display module.
[0119] The high strength and reliability of the colloid can reduce damage to the display module caused by internal collisions, as well as damage to the display module caused by collisions with other components outside the display module, during transportation, assembly, and / or use of the display module, further improving safety. In some embodiments, the colloid is formed to wrap around the flexible circuit board, and the colloid adheres the display screen and the flexible circuit board, including:
[0120] Placing the flexible circuit board in a mold and placing the display screen outside the mold;
[0121] The fluid colloid is injected through the injection hole on the mold.
[0122] The mold may be provided with a plurality of glue injection holes to facilitate injection of the colloid.
[0123] The specific size of the mold matches the size of the display module, which facilitates the placement of the display module.
[0124] After the colloid is solidified, the mold is opened and the display screen is taken out of the mold.
[0125] For example, a display screen may have multiple flexible circuit boards at the same time. In this way, the outer sides of multiple flexible circuit boards can be formed into a colloid at one time, thereby improving the production efficiency of the display module.
[0126] For example, the colloids of multiple flexible circuit boards may be connected into a whole, or the colloids of different flexible circuit boards may be separately arranged.
[0127] In the embodiment of the present disclosure, the mold can be heated to a preset temperature to accelerate the curing of the colloid. Specifically, the preset temperature should be lower than the tolerable temperature of the display module to reduce possible damage to the display module caused by the temperature.
[0128] In some embodiments, the method further comprises:
[0129] placing a bracket in the frame;
[0130] bonding the frame and the bracket;
[0131] The forming of the colloid wrapping the flexible circuit board, wherein the colloid adheres the display screen and the flexible circuit board, comprises:
[0132] After the frame and the bracket are bonded together, the colloid wrapping the flexible circuit board is formed, and the colloid bonds the display screen and the flexible circuit board together.
[0133] For example, the frame and bracket are fixed relative to each other through adhesive bonding, screws, or latches. Once fixed relative to each other, the frame and bracket form a single unit. The display module is assembled into the frame and mounted on the bracket. A fluid colloid material is then injected through the glue injection holes and solidifies to form a gel, completing the installation of the display module.
[0134] In the embodiment of the present disclosure, a bracket can be set in the frame, and then a fluid colloid can be injected through the glue injection hole on the frame. After the colloid is solidified, the bracket, the colloid and the display screen are integrated with the flexible circuit board, which facilitates the transportation and assembly of the display module. At the same time, by introducing the bracket, the display screen can be better supported and protected.
[0135] In some embodiments, the method further comprises:
[0136] Adhere the colloid to the bottom surface of the frame by dispensing glue;
[0137] and / or,
[0138] The colloid is bonded to the side surface of the frame by dispensing glue.
[0139] In the embodiment of the present disclosure, the colloid may be bonded to the bottom surface of the frame by adhesive and / or the colloid may be bonded to the side surface of the frame by adhesive.
[0140] In some embodiments, the method further comprises:
[0141] Bonding the bracket to the bottom surface of the frame by dispensing glue;
[0142] and / or,
[0143] The bracket is bonded to the side surface of the frame by dispensing glue.
[0144] In the embodiment of the present disclosure, by bonding the bracket to the frame, the bracket, the frame, the colloid, the display screen and the flexible circuit board are integrated, which can provide better support and protection for the display screen.
[0145] The structural diagram of the design scheme of the mobile phone screen in the related art is as follows Figure 3 As shown, it includes a screen 11, a back glue 12 and a middle frame 13. The middle frame here can be one of the aforementioned frames. Figure 3 It can be seen that the current size of the bottom black border is composed of three parts: the black border of the screen itself (B), the safety gap between the screen and the middle frame (C), and the glue width between the screen and the middle frame (D), that is, the black border of the whole machine A=B+C+D.
[0146] This structure may have the following problems: 1. If the black border (B) of the screen itself is further reduced, the cost of the screen will increase significantly, and there is not much room for compression on the screen end, and it has reached a bottleneck.
[0147] 2. Continuing to reduce the gap between the screen CG and the middle frame glue point width (D) will result in poor reliability and increase the risk of the screen debonding.
[0148] Therefore, based on this, the present disclosure also proposes a design solution to reduce the black border of the mobile phone screen and protect the screen safety. Figure 4 The figure shows a structural diagram of a design scheme for reducing the black border of a mobile phone screen and protecting the screen safety provided by an embodiment of the present disclosure. Figure 1 .Depend on Figure 4 It can be seen that the structure includes a screen 11, adhesive backing 12, a middle frame 13 and a filling structural adhesive 14. A new type of filling structural adhesive is used in the embodiment of the present disclosure. A simple mold is used to allow the structural adhesive to completely fill the flexible circuit board (FPC) area at the bottom of the screen circumference (the entire screen circle can also be filled). After the structural adhesive solidifies, it forms a plastic bracket that firmly integrates the screen to form a new display module. This also provides good protection for the screen unit during transportation and assembly. The whole machine is assembled by gluing the display module and the middle frame together through adhesive backing or glue. This solution eliminates the adhesive width between the screen glass and the middle frame. The black edge A of the whole machine consists of two parts: the black edge B of the screen itself and the safety gap C from the FPC to the middle frame. This greatly reduces the black edge of the screen and increases the screen-to-body ratio of the whole machine. The screen is a type of the aforementioned display screen, the structural adhesive is a type of the aforementioned colloid, and the middle frame is a type of the aforementioned frame.
[0149] like Figure 5 The figure shows a structural diagram of a design scheme for reducing the black border of a mobile phone screen and protecting the screen safety provided by an embodiment of the present disclosure. Figure 2 .Depend on Figure 5 As can be seen, the structure includes a screen 11, adhesive backing 12, a middle frame 13, filler structural adhesive 14, and a screen protection plastic bracket 15. The inclusion of the screen protection bracket in the disclosed embodiment facilitates the formation of the display module and improves the yield rate during transportation and assembly. The screen protection plastic bracket is a variant of the aforementioned bracket.
[0150] The design solution provided by the present disclosure, which reduces the black border of the mobile phone screen and protects the screen safety, has the following features:
[0151] 1. Compared with the conventional solution, this solution eliminates the glue dot area where the screen glass step and the middle frame overlap, greatly reducing the black edge of the screen.
[0152] 2. This solution does not damage the integrity of the middle frame, ensuring the strength of the middle frame and greatly improving the reliability and strength of the entire device.
