Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a mask fastener, connector and display module. Background Technology

[0002] A display module typically includes a back cover, a backlight panel, a front cover, and connectors. The connectors are mounted on the backlight panel, and the back cover, backlight panel, and front cover are fixed together. The connectors can be located in the middle of the display module or on one of its longer sides. For display modules requiring curved displays, the back cover, backlight panel, and front cover must remain in close contact with each other when the curvature and direction of the curve change to ensure optimal display quality.

[0003] Due to the connector configuration, there are no fixing points between the lamp board and the mask in the display module and the back cover at the connector. For display modules with the connector located in the middle, when the display module is curved in a concave arc, some gaps may easily appear between the mask and the lamp board in the middle position, resulting in poor fit and affecting the display effect of the display module. Utility Model Content

[0004] This application provides a mask fastener, a connector, and a display module to solve the technical problem in the related art where gaps easily appear between the mask and the light panel in the middle position, resulting in poor fitting and affecting the display effect of the display module.

[0005] To address the aforementioned issues, this application provides a display module comprising a rear shell, a lamp plate disposed on one side of the rear shell, a face shield disposed on the side of the lamp plate facing away from the rear shell, a connector disposed on the side of the lamp plate facing the rear shell, and a face shield fixing member.

[0006] The mask fastener is located on the side of the lamp panel facing the rear shell, and the mask fastener is used to cooperate with fasteners to fix the lamp panel and the mask together.

[0007] In some embodiments, the mask fastener is located in the area covered by the connector;

[0008] The mask fastener has a plurality of fastening portions, and the fastening portions have connecting holes, through which the mask fastener engages with a fastener.

[0009] In some embodiments, a plurality of the fixing parts form at least two sets of combined fixing parts, each set of combined fixing parts including at least two fixing parts, and adjacent sets of combined fixing parts are connected by reinforcing ribs.

[0010] In some embodiments, the reinforcing ribs and each group of the combined fixing parts form a triangular structure.

[0011] In some embodiments, the at least two sets of combined fixing parts are arranged along a first direction, and the fixing parts in each set of combined fixing parts are arranged along a second direction, wherein the first direction and the second direction are perpendicular.

[0012] The combined fixing parts arranged at the ends include three fixing parts, with the middle fixing part having an extension on the side opposite to the reinforcing rib, the extension extending along the first direction.

[0013] In some embodiments, at least two of the plurality of fixing portions have positioning protrusions formed on them.

[0014] The lamp plate has positioning holes that mate with the positioning protrusions.

[0015] In some embodiments, the connector includes:

[0016] Pin header;

[0017] A plurality of pins are arranged on the pin holder, one end of the pins forming a plug-in end and the other end forming a connection end. The connection end is connected to the lamp board, and the pins form a receiving space on the side of the pin holder facing the connection end. The receiving space is used to receive the mask fixing component.

[0018] This application also provides a mask fastener, which is used in a display module to connect the mask and the light panel;

[0019] The mask fastener has a plurality of fastening portions, and the fastening portions have connecting holes for engaging with fasteners.

[0020] The plurality of fixing parts form at least two sets of combined fixing parts, each set of combined fixing parts including at least two fixing parts, and adjacent sets of combined fixing parts are connected by reinforcing ribs.

[0021] In some embodiments, at least two of the plurality of fixing portions have positioning protrusions formed on them, the positioning protrusions being used to engage with positioning holes on the lamp plate to position the relative positions of the mask fixing member and the lamp plate.

[0022] This application also provides a connector for use in a display module to mate with any of the mask fixing components described above;

[0023] The connector includes:

[0024] Pin header;

[0025] A pin header is arranged on the pin header seat. One end of the pin header forms a plug-in end and the other end forms a connection end. The connection end is used to connect with the lamp board. The pin header forms a receiving space on the side of the pin header seat facing the connection end. The receiving space is used to receive the mask fixing component.

[0026] The beneficial effects of the embodiments of this application are as follows: The display module provided by this application can fix the lamp board and the mask at the connector by setting a mask fixing member on the side of the lamp board facing the rear shell. For display modules with the connector located in the middle position, when the display module is curved in a concave arc, a gap appears between the mask and the lamp board in the middle position, which ensures the fitting effect between the mask and the lamp board in the display module, thereby ensuring the display effect of the display module.

[0027] When one end of the fixing part in the face mask fastener has an extension, it facilitates the staff or assembly robot to hold the face mask fastener in the designated position during the assembly of the display module.

[0028] When a positioning protrusion is formed on the fixing part of the mask fastener, and the positioning protrusion mates with the positioning hole on the lamp plate, the mask fastener can be quickly installed in place. At the same time, the mate between the positioning protrusion and the positioning hole can be used to restrict the relative movement between the mask fastener and the lamp plate.

[0043] Please see Figures 1 to 3 and Figure 5 This application provides a display module, which includes a back cover 10, a lamp board 20, a face mask 30, a connector 40, and a face mask fixing member 50. The lamp board 20 is disposed on one side of the back cover 10, the face mask 30 is disposed on the side of the lamp board 20 facing away from the back cover 10, the connector 40 is disposed on the side of the lamp board 20 facing the back cover 10, and the face mask fixing member 50 is disposed on the side of the lamp board 20 facing the back cover 10. The face mask fixing member 50 is used to cooperate with a fastener 60 to fix the lamp board 20 and the face mask 30 together.

[0044] It should be noted that, as Figure 3As shown, in the display module, the back cover 10 has several fixing points 12 on one side for mounting the lamp panel 20. Fasteners 60 pass through the faceplate 30 and the lamp panel 20 in sequence and are fixed at the fixing points 12, thereby fixing the lamp panel 20 and the faceplate 30 to the back cover 10 together. Since the connector 40 needs to connect to other external devices to transmit display information to the display module and to power the display module, the back cover 10 has an clearance opening 11 at the connector 40. Therefore, the faceplate 30 and the lamp panel 20 in the display module cannot be fixed to the back cover 10 at the connector 40, and there is also a lack of fixed connection between the lamp panel 20 and the faceplate 30. Thus, when the display module is bent into a concave arc, the lamp panel 20 and the faceplate 30 are prone to misfitting. This application achieves a fixed connection between the light panel 20 and the mask 30 by setting a mask fixing member 50 at the connector 40, so that the fastener 60 passes through the mask 30 and the light panel 20 in sequence and is fixed on the mask fixing member 50. When the display module is bent into a concave arc, the fastener 60 can pull the mask 30 towards the light panel 20, thereby effectively ensuring the fit between the mask 30 and the light panel 20.

[0045] In the display module, the mask fixing member 50 is disposed on the side of the lamp plate 20 facing the rear shell 10. For example, in some embodiments, the mask fixing member 50 may be located in the area covered by the connector 40. The area covered by the connector 40 refers to the orthographic projection area of ​​the connector 40 on the side of the lamp plate 20 facing the rear shell 10. Thus, when the fastener 60 passes through the mask 30 and the lamp plate 20 at the connector 40, the mask fixing member 50 can provide a fixing point 12 for the end of the fastener 60 passing through the lamp plate 20, thereby achieving a fixed connection between the mask 30 and the lamp plate 20.

[0046] Please refer to the following: Figure 4 The connector 40 is located on the side of the lamp board 20 facing the rear housing 10. It can be understood that the connector 40 generally includes a male and a female connector; the connector being located on the side of the lamp board facing the rear housing indicates that the male end of the connector is connected to the PCB board of the lamp board 20. For example... Figure 4As shown, the male end of the connector 40 generally includes a pin header 41 and pins 42 arranged on the pin header 41. The end of the pins 42 that connects to the lamp board 20 is generally arranged in two rows to facilitate connection with the lamp board 20. The mask fixing member 50 can be disposed between the two rows of pins 42. In some embodiments, the connector 40 in the display module may include a pin header 41 and pins 42 arranged on the pin header 41. One end of the pin 42 forms a plug-in end 421, and the other end forms a connection end 422. The connection end 422 connects to the lamp board 20. At the same time, the pins 42 form a receiving space 43 on the side of the pin header 41 facing the connection end 422, and the receiving space 43 is used to receive the mask fixing member 50. It can be understood that the plug-in end 421 of the pin 42 is located on the side of the pin header 41 for mating with the female connector, and the connection end 422 of the pin 42 is located on the side of the pin header 41 facing the lamp board 20. When the connecting ends 422 of the pin header 42 are arranged in two rows, the accommodating space 43 is the space enclosed by the two rows of pin headers 42 and the pin header seat 41. It should be noted that since the mask fixing member 50 needs to cooperate with the fastener 60, the mask fixing member 50 needs to have a certain thickness along the axial direction of the fastener 60. Correspondingly, after the connector 40 is connected to the lamp board 20, the distance between the lamp board 20 and the pin header seat 41 needs to be sufficient to accommodate the mask fixing member 50. The distance between the lamp board 20 and the pin header seat 41 is determined by the length of the connecting ends 422 of the pin header 42. In this embodiment, the specific length of the connecting ends 422 of the pin header 42 is not limited; it can be set according to the thickness of the mask fixing member 50. It should be noted that to avoid the mask fixing member 50 affecting the electrical connection between the connector 40 and the lamp board 20, the mask fixing member 50 is made of insulating material, such as plastic.

[0047] Since the face mask fastener 50 provides a fixing point 12 for the end of the fastener 60 that passes through the lamp panel 20, to ensure the fixing effect of the fastener 60 and the face mask fastener 50 on the lamp panel 20 and the face mask 30, it can be understood that the surface of the face mask fastener 50 facing the lamp panel 20 can be in close contact with the lamp panel 20. The specific setting method of the face mask fastener 50 on the side of the lamp panel 20 facing the rear shell 10 can be direct placement, adhesive connection, or one of them having a positioning hole and the other having a positioning protrusion 54, with the positioning hole and positioning protrusion 54 cooperating, but it is not limited to these methods.

[0048] The specific mating method between the face mask fastener 50 and the fastener 60 depends on the structure of the fastener 60. For example, the fastener 60 can be selected from standard fasteners such as screws and bolts, or it can be a non-standard part. When the fastener 60 is a screw or bolt, the face mask fastener 50 can be provided with a bottom hole for mating with the screw or a threaded hole for mating with the bolt. When the fastener 60 is a non-standard part, for example, Figure 6As shown, when the fastener 60 is a fixing pin with a circumferentially formed snap-fit ​​protrusion 61, the mask fixing member 50 can have a mating hole with a snap-fit ​​groove. In some embodiments, the mask fixing member 50 has a plurality of fixing portions 51, and the fixing portions 51 have connecting holes 52, through which the mask fixing member 50 mates with the fastener 60. Depending on the structure of the fastener 60, the connecting hole 52 can be a bottom hole, a threaded hole, or a mating hole with a snap-fit ​​groove, but is not limited thereto. The fixing portion 51 can be a cylindrical solid, a rectangular block solid, or a hemispherical solid, but is not limited thereto; in this embodiment, a cylindrical solid is used as an example for illustration.

[0049] Please refer to the following: Figure 7 and Figure 8 In some embodiments, the plurality of fixing parts 51 can form at least two sets of combined fixing parts 51a, each set of combined fixing parts 51a including at least two fixing parts 51, and adjacent sets of combined fixing parts 51a are connected by reinforcing ribs 53.

[0050] The combined fixing parts 51a in the mask fixing member 50 can be arranged along a first direction, and the fixing parts 51 in each group of combined fixing parts 51a can be arranged along a second direction, with the first and second directions perpendicular to each other. The specific number of combined fixing parts 51a in the mask fixing member 50 and the specific number of fixing parts within each group of combined fixing parts 51a are not limited; they can be set according to the specific coverage area of ​​the connector 40 on the lamp panel 20. Furthermore, the number of fixing parts in multiple groups of combined fixing parts 51a in the mask fixing member 50 can be the same or different. Figure 8 As shown, in some embodiments, the mask fastener 50 includes two sets of combined fastening portions 51a, each set of combined fastening portions 51a having three fastening portions. For example... Figure 7 As shown, in some embodiments, the mask fastener 50 includes at least three sets of combined fastening parts 51a. The combined fastening parts 51a at both ends each include three fastening interiors, and the combined fastening parts 51a in the middle each include two fastening parts.

[0051] In the mask fastener 50, adjacent sets of combined fastening parts 51a are connected by reinforcing ribs 53, thereby connecting the sets of combined fastening parts 51a into a whole. For example... Figure 7 and Figure 8 As shown, in some embodiments, the reinforcing rib 53 and each set of fixing parts 51a can form a triangular structure, thereby enhancing the overall stability of the mask fixing member 50. When the mask fixing member 50 is placed into the receiving space 43 of the connector 40, bending of the mask fixing member 50 can be avoided, facilitating installation and positioning.

[0052] like Figure 7 and Figure 8As shown, in some embodiments, the combined fixing portions 51a arranged at the ends of the mask fixing member 50 include three fixing portions 51. The middle fixing portion 51 has an extension portion 55 formed on the side opposite to the reinforcing rib 53, and the extension portion 55 extends along the arrangement direction of the combined fixing portions 51a. By forming the extension portion 55 in the mask fixing, it is convenient for workers or assembly robots to hold the mask fixing member 50 during the display module assembly process, so as to install the mask fixing member 50 into the designated position. It should be noted that the extension portion 55 is a structural feature on the mask fixing member 50 for facilitating assembly. When the lamp plate 20 is assembled onto the back shell 10 and the connector 40 is inserted into the corresponding clearance opening 11 on the back shell 10, the extension portion 55 may interfere with the back shell 10. Therefore, after the mask fixing member 50 is assembled in place, the part of the extension portion 55 that may affect the assembly can be cut off according to the specific fit.

[0053] like Figure 8 As shown, in some embodiments, at least two of the fixing portions 51 have positioning protrusions 54 formed on them. It is understood that the lamp plate 20 in the display module has positioning holes that mate with the positioning protrusions 54. For example, the positioning protrusions 54 on the fixing portions 51 can be arranged coaxially with the connecting holes 52. By forming positioning protrusions 54 on at least two of the fixing portions 51, and having the positioning protrusions 54 mate with the positioning holes on the lamp plate 20, the mask fixing member 50 can be quickly installed in place, while the relative movement between the mask fixing member 50 and the lamp plate 20 can be limited by the engagement of the positioning protrusions 54 and the positioning holes.

[0054] like Figure 7 and Figure 8 As shown, in some embodiments, this application also provides a face mask fastener 50, which is applied in a display module to connect the face mask 30 and the lamp panel 20. The face mask fastener 50 has a plurality of fastening portions 51, and each fastening portion 51 has a connecting hole 52 for engaging with a fastener 60. The plurality of fastening portions 51 form at least two sets of combined fastening portions 51a, each set of combined fastening portions 51a including at least two fastening portions 51, and adjacent sets of combined fastening portions 51a are connected by reinforcing ribs 53.

[0055] The explanation of the face mask fixing member 50 in this embodiment is the same as that in the above-described display module embodiment, and will not be repeated here.

[0056] like Figure 4As shown, in some embodiments, this application also provides a connector 40, which is used in a display module to mate with a face mask fastener 50. The connector 40 includes a pin header 41 and pins 42. The pins 42 are arranged on the pin header 41, with one end forming a plug-in end 421 and the other end forming a connection end 422. The connection end 422 is used to connect to the lamp board 20, and the pins 42 form a receiving space 43 on the side of the pin header 41 facing the connection end 422, the receiving space 43 being used to receive the face mask fastener 50.

[0057] The explanation of connector 40 in this embodiment is the same as that of mask fixing member 50 in the above-mentioned display module embodiment, and will not be repeated here.

[0058] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
