Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] Display modules typically include key components such as LCD panels, printed circuit board assemblies (PCBAssembly, PCBa), and backlight modules. The PCBa has connectors, and the backlight module contains LED strips, which are connected to connectors on the PCBa via flexible circuit boards.

[0003] Display modules can be divided into two types based on the shape of the PCBa: bent display modules and flattened display modules. In flattened display modules, the PCBa is flattened and fixed to the bottom side of the display panel, and the width of the bottom bezel of the display module is limited by the width of the PCBa. Utility Model Content

[0004] This application provides a display device to solve the technical problem of how to reduce the width of the bezel of the display device.

[0005] To achieve the above objectives, according to a first aspect of this application, a display device is provided, comprising:

[0006] A backlight module, including a backlight body and a first flexible circuit board connected to the backlight body;

[0007] A printed circuit board is disposed on one side of the backlight body;

[0009] The first flexible circuit board is disposed on the side of the backlight body away from the light-emitting surface of the backlight module, and part of the first flexible circuit board overlaps with the backlight body. The end of the first flexible circuit board away from the backlight body is connected to the connector.

[0010] Optionally, both the printed circuit board and the connector extend along a first direction.

[0011] Optionally, the first flexible circuit board includes an extension and a connector connected together, the extension being located on the side of the printed circuit board near the backlight body, and the connector being connected to the connector.

[0012] Optionally, the length of the extension in the second direction is greater than the length of the printed circuit board in the second direction, and the second direction is perpendicular to the first direction.

[0013] Optionally, the extension length of the extension is greater than the length of the extension in the second direction.

[0015] Optionally, the connector has an engagement opening at one end near the extension, and the connector head at the other end away from the extension is located within the engagement opening.

[0016] Optionally, the backlight body includes a back plate and a light strip disposed in the back plate. The back plate has a slot near the edge of the printed circuit board, and the first flexible circuit board passes through the slot and is connected to the light strip.

[0017] Optionally, a support member is provided at the edge of the backlight body, the support member extends in a direction away from the backlight body, and the support member is connected to the printed circuit board.

[0018] Optionally, the display device further includes:

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0045] To achieve the above objectives, according to the first aspect of this application, such as Figures 1 to 7 As shown, Figure 1 This is a top view of a display device 1 provided in an exemplary embodiment of this disclosure. Figure 1 One side surface of the display surface of the display device 1 is shown. Figure 2 This is a bottom view of a display device 1 provided in an exemplary embodiment of this disclosure. Figure 2 The side surface of the display device 1 facing away from the display surface is shown. This application provides a display device 1, including a backlight module 10, a printed circuit board 20, and a connector 30. The backlight module 10 includes a backlight body 11 and a first flexible circuit board 12 connected to the backlight body 11; the printed circuit board 20 is disposed on one side of the backlight body 11; the connector 30 is disposed on the printed circuit board 20; wherein, the first flexible circuit board 12 is disposed on the side of the backlight body 11 facing away from the light-emitting surface 10a of the backlight module 10, and a portion of the first flexible circuit board 12 overlaps with the backlight body 11, and the end of the first flexible circuit board 12 away from the backlight body 11 is connected to the connector 30.

[0046] The display device 1 can be a liquid crystal display device, and the backlight module 10 is used to provide a backlight for the liquid crystal panel, etc.

[0047] like Figure 2 , Figure 3 and Figure 7 As shown, the backlight module 10 includes a backlight body 11 and a first flexible circuit board 12 connected to the backlight body 11. The backlight module 10 has a light-emitting surface 10a, which can be used to provide a planar light source. The first flexible circuit board 12 is used to connect to a connector 30, and power and other supplies are input to the backlight body 11 through the connector 30.

[0048] The printed circuit board 20 is equipped with components, including connectors 30, chips, resistors, capacitors, etc. The printed circuit board 20 is used to carry the components and realize the electrical connection between the components to ensure the circuit function.

[0049] like Figure 3 and Figure 7 As shown, the printed circuit board 20 is disposed on one side of the backlight body 11, which means that the printed circuit board 20 does not overlap with the light-emitting surface 10a of the backlight module 10, i.e., the display device 1 is in a flattened form.

[0050] like Figure 3 and Figure 4 As shown, connector 30 is disposed on printed circuit board 20. Connector 30 can be fixed to printed circuit board 20 by means of soldering or other methods, and connector 30 is electrically connected to printed circuit board 20. The circuit formed by printed circuit board 20 and components can input power signals such as power to backlight body 11 through connector 30 and first flexible circuit board 12 to drive backlight body 11 to emit light.

[0051] like Figure 7 As shown, the first flexible circuit board 12 is disposed on the side of the backlight body 11 away from the light-emitting surface 10a of the backlight module 10, and a portion of the first flexible circuit board 12 overlaps with the backlight body 11. This arrangement reduces the area of ​​the first flexible circuit board 12 extending out of the backlight body 11 and overlapping with the printed circuit board 20, thereby preventing the first flexible circuit board 12 from occupying excessive component layout space on the printed circuit board 20. This arrangement also reduces the size of the printed circuit board 20, thereby reducing the width of the bezel of the display device 1.

[0052] In some embodiments, such as Figure 7 As shown, the backlight body 11 includes a back plate 112. The back plate 112 includes a base plate 1121 and side plates 1122 disposed around the base plate 1121. The side plates 1122 and the base plate 1121 together form an accommodating space. A light source assembly can be disposed within the accommodating space of the back plate 112.

[0053] In some embodiments, the material of the back plate 112 may be stainless steel, iron, aluminum or other metal materials.

[0054] like Figure 7 As shown, the light source assembly may include a reflective sheet 115, a light guide plate 114, and an optical film 116 stacked in sequence.

[0055] In some embodiments, such as Figure 7As shown, a light strip 113 is also provided within the accommodating space, and the light strip 113 is disposed on one side wall of the light guide plate 114. The light strip 113 includes LED beads 1132, which can be LEDs or the like. The light emitted from the LED beads 1132 is incident on the side wall of the light guide plate 114, and is conducted through the light guide plate 114 to the entire plane of the light guide plate 114, thereby forming a planar light source.

[0056] In some embodiments, the light guide plate 114 may be made of a transparent polymer material, such as polymethyl methacrylate (PMMA) or polycarbonate (PC).

[0057] like Figure 7 As shown, the reflector 115 is disposed on the side of the light guide plate 114 near the base plate 1121. The reflector 115 is mainly used to reflect the light emitted from the bottom of the light guide plate 114 back into the light guide plate 114, so that it can be concentrated and emitted from the front of the light guide plate 114, reducing light loss and increasing the light source efficiency of the backlight module 10.

[0058] In some embodiments, a reflective strip (not shown in the figure) is provided on the other side wall of the light guide plate 114 that is not provided with the light strip 113. The reflective strip is used to reflect the light emitted from the side of the light guide plate 114, so that it can be concentrated and projected from the front, further reducing light loss and increasing the light source efficiency of the backlight module 10.

[0059] like Figure 7 As shown, an optical film 116 is disposed on the side of the light guide plate 114 facing away from the base plate 1121. The optical film 116 may include diffuser sheets, prism sheets, etc., stacked sequentially. The diffuser sheet is used to diffusely reflect the light emitted from the light guide plate 114, so that the light is evenly distributed on the light-emitting surface 10a, effectively homogenizing the light. The prism sheet is disposed on the side of the diffuser sheet away from the light guide plate 114. The prism sheet corrects the direction of the light through the principle of light refraction and reflection, concentrating the scattered light towards the front, thereby improving the brightness of the backlight module 10.

[0060] like Figure 7 As shown, the light-emitting surface 10a of the backlight module 10 refers to the side surface of the optical film 116 facing away from the base plate 1121. The light-emitting surface 10a of the backlight module 10 is correspondingly arranged to the display area of ​​the liquid crystal panel, which means that the backlight module 10 can provide a planar light source for at least the entire display area of ​​the liquid crystal panel.

[0061] In some embodiments, the backlight module 10 further includes a middle frame (not shown in the figure), which is disposed in the receiving cavity and is disposed corresponding to the edge of the back plate 112. The middle frame is used to fix the light source assembly of the backlight module 10, ensure the structural stability of the backlight module 10, and also play a certain role in light shielding and protection.

[0062] In some embodiments, the material of the middle frame can be plastic or the like. The middle frame can be integrally formed by injection molding. Specifically, the plastic raw material is heated and melted, then injected into a specific mold cavity, cooled and solidified within the mold, forming the middle frame in one step.

[0063] The mid-frame may include a connecting plate and a support plate connected to the connecting plate. The connecting plate may be engaged with the side plate 1122 of the back plate 112, but is not limited thereto. The support plate may extend into the receiving space of the back plate 112, and a limiting structure may be provided on the support plate to position the optical film 116 and prevent the optical film 116 from moving within the receiving space of the back plate 112.

[0064] like Figure 7 As shown, the backlight body 11 may further include an adhesive portion 117, which is double-sided adhesive. The adhesive portion 117 is disposed around the edge of the backlight body 11, and is used to bond and fix the edge of the optical film 116 to the mid-frame. The side surface of the adhesive portion 117 facing away from the base plate 1121 is used to bond with the liquid crystal panel, etc. The adhesive portion 117 is a light-shielding tape or the like, and can shield the edge of the backlight body 11 from light, preventing light leakage from the edge of the backlight body 11.

[0065] Optionally, such as Figure 3 As shown, both the printed circuit board 20 and the connector 30 extend along the first direction D1.

[0066] The printed circuit board 20 extends along the first direction D1, meaning that the printed circuit board 20 has a long side and a short side, with the long side extending in the first direction D1. The connector 30 extends along the first direction D1, meaning that the connector 30 has a long side and a short side, with the long side extending in the first direction D1.

[0067] like Figure 3 and Figure 7 As shown, the printed circuit board 20 is disposed on one side of the backlight body 11, and the first direction D1 can be the same as the extension direction of the outline of the backlight body 11, thereby avoiding increasing the bezel width of the display device 1.

[0068] Optionally, such as Figure 3 and Figure 7 As shown, the first flexible circuit board 12 includes an extension 121 and a connector 122 connected to each other. The extension 121 is located on the side of the printed circuit board 20 near the backlight body 11, and the connector 122 is connected to the connector 30.

[0069] like Figure 3 and Figure 7As shown, the extension 121 is located on the side of the printed circuit board 20 near the backlight body 11. That is to say, the extension 121 is disposed on the back side of the backlight body 11 and overlaps with the backlight body 11. With the above arrangement, the overlap between the extension 121 and the printed circuit board 20 can be further avoided, so that the extension 121 occupies the layout space of the components on the printed circuit board 20.

[0070] In some embodiments, such as Figure 3 and Figure 7 As shown, one end of connector 122 is connected to connector 30, and the other end is connected to extension 121. Connector 122 and connector 30 are detachably connected, and connector 122 can be inserted into connector 30.

[0071] Optionally, such as Figure 3 As shown, the length s1 of the extension 121 in the second direction D2 is greater than the length s2 of the printed circuit board 20 in the second direction D2, and the second direction D2 is perpendicular to the first direction D1. Here, the length s1 of the extension 121 in the second direction D2 refers to the dimension of the outline of the extension 121 in the second direction D2. The length s2 of the printed circuit board 20 in the second direction D2 refers to the width of the printed circuit board 20. Since the printed circuit board 20 is disposed on one side of the backlight body 11, the width of the printed circuit board 20 affects the width of the bezel of the display device 1. The wider the printed circuit board 20, the wider the bezel of the display device 1.

[0072] In related technologies, the extension 121 overlaps with the printed circuit board 20. When the length s1 of the extension 121 in the second direction D2 is greater than the length s2 of the printed circuit board 20 in the second direction D2, the extension 121 will extend beyond the printed circuit board 20 in the second direction D2 and be suspended. This makes the extension 121 susceptible to damage from external forces. To protect the extension 121, the size of the printed circuit board 20 in the second direction D2 must be increased to support the extension 121 and prevent it from being suspended. This increases the size of the printed circuit board 20 in the second direction D2, thus increasing the bezel of the display device 1.

[0073] In this application, such as Figure 3 As shown, by setting the extension 121 to overlap with the backlight body 11, the length s1 of the extension 121 in the second direction D2 will not affect the length s2 of the printed circuit board 20 in the second direction D2. That is to say, the length s2 of the printed circuit board 20 in the second direction D2 can be smaller than the length s1 of the extension 121 in the second direction D2, thereby reducing the bezel width of the display device 1.

[0074] It should be understood that the length s1 of the extension 121 in the second direction D2 cannot be too small. Since the connector 122 needs to be connected to the connector 30, when the length s1 of the extension 121 in the second direction D2 is too small, the extension 121 will have limited space for movement, which is not conducive to personnel operating the connector 122, and it is also not easy to realize the insertion of the connector 122 and the connector 30.

[0075] Optionally, such as Figure 3 As shown, the extension length s3 of the extension 121 is greater than the length s1 of the extension 121 in the second direction D2. The extension length s3 of the extension 121 refers to the length of the central axis of the extension 121. The central axis is the line connecting all the midpoints of the extension 121 in the width direction, which is perpendicular to the extension direction of the extension 121. The extension length s3 of the extension 121 is... Figure 3 The length of the U-shaped dashed line in the middle.

[0076] For example, when the extension 121 is rectangular, the central axis is the line connecting the midpoints of the two shorter sides of the rectangle, and the length of the central axis is the length of the longer side of the rectangle. When the extension 121 is U-shaped, all the midpoints of the extension 121 in the width direction are located on the central axis, and the central axis of the extension 121 is also U-shaped. The extension 121 can also be other shapes, and this application does not limit this.

[0077] In some embodiments, to increase the mobility of the connector 122 and make it easier for personnel to connect the connector 122 to the connector 30, the extension 121 may extend in at least two directions. For example, the extension direction of the extension 121 may be a broken line, a curve, etc.

[0078] Optionally, such as Figure 3 As shown, the extension 121 is U-shaped, with one end of the extension 121 connected to the backlight body 11 and the other end of the extension 121 connected to the connector 122.

[0079] In some embodiments, the extension 121 is U-shaped. This configuration allows the extension 121 to extend in two directions, connected by an arc. Since the arc connection is less prone to tearing under external force, the risk of breakage of the extension 121 due to improper operation is reduced.

[0080] like Figure 4 and Figure 6 As shown, one end of the extension 121 is connected to the backlight body 11. Specifically, one end of the extension 121 can be connected to the light strip 113 to provide power to the light strip 113 so as to drive the light strip 113 to light up.

[0081] Optionally, the connector 30 is provided with a snap-fit ​​opening 30a at one end near the extension 121, and the connector head 122 is located in the snap-fit ​​opening 30a at the other end away from the extension 121.

[0082] In some embodiments, such as Figure 6 As shown, the connector 122 includes multiple connection terminals 1221, and the connector 30 includes multiple signal terminals. One connection terminal 1221 is electrically connected to one signal terminal, thereby realizing signal transmission.

[0083] like Figure 4 As shown, the connector 122 can be inserted into the snap-fit ​​opening 30a. The connection terminal 1221 is located on the side surface of the connector 122 closest to the printed circuit board 20. The connection terminal 1221 overlaps with the signal terminal, and the side surface of the connection terminal 1221 closest to the signal terminal contacts the side surface of the signal terminal closest to the connection terminal 1221 to form a conductive connection. Closing the snap-fit ​​opening 30a locks the connector 122 and the connector 30 together.

[0084] It should be noted that the snap-fit ​​opening 30a can be opened to separate the connector 122 from the connector 30. Figure 5 The diagram shows the state when the connector 122 is separated from the connector 30. The engagement opening 30a can be closed to lock the connector 122 and the connector 30 together, thus achieving an electrical connection between the connector 122 and the connector 30. Figure 3 The diagram shows the state when the connector 122 is locked to the connector 30.

[0085] Optionally, the backlight body 11 includes a back plate 112 and a light strip 113 disposed in the back plate 112. The back plate 112 has a slot 112a near the edge of the printed circuit board 20. The first flexible circuit board 12 passes through the slot 112a and is connected to the light strip 113.

[0086] In some embodiments, the light strip 113 includes a third flexible circuit board 1131 and a plurality of LED beads 1132, which can be soldered onto the third flexible circuit board 1131. The LED beads 1132 can be LEDs, etc.

[0087] In some embodiments, such as Figure 6 As shown, the third flexible circuit board 1131 is integrally formed with the first flexible circuit board 12. This means that the third flexible circuit board 1131 and the first flexible circuit board 12 are made of the same material and are continuously formed. This arrangement simplifies the processing technology of the third flexible circuit board 1131 and the first flexible circuit board 12.

[0088] Specifically, one end of the extension 121 is connected to the third flexible circuit board 1131, and the other end is connected to the connector 122.

[0089] In other embodiments, the third flexible circuit board 1131 and the first flexible circuit board 12 are separately disposed. That is to say, the third flexible circuit board 1131 and the first flexible circuit board 12 are formed separately and then connected by means of welding or the like.

[0090] Please see Figures 4 to 6 When not plugged in, the first flexible circuit board 12 extends toward the printed circuit board 20. During assembly, the first flexible circuit board 12 is bent toward the side closer to the back plate 112 until it overlaps with the back plate 112, and then the connector 122 is plugged into the connector 30.

[0091] Optionally, such as Figure 2 As shown, a support member 13 is provided on the edge of the backlight body 11. The support member 13 extends in a direction away from the backlight body 11 and is connected to the printed circuit board 20.

[0092] The support member 13 extends away from the backlight body 11 and overlaps with the printed circuit board 20. The support member 13 is connected to the printed circuit board 20 to support and fix the printed circuit board 20.

[0093] In some embodiments, the support member 13 is detachably connected to the printed circuit board 20. For example, the printed circuit board 20 may have screw holes, and the support member 13 may have corresponding screw holes, with the printed circuit board 20 and the support member 13 screwed together.

[0094] In some embodiments, such as Figure 2 As shown, the support member 13 can be integrally formed with the back plate 112. Specifically, the support member 13 can be formed from a portion of the material at the edge of the base plate 1121 through stamping and bending processes, so that the support member 13 extends in a direction away from the back plate 112 to overlap with the printed circuit board 20. With the above arrangement, the manufacturing process of the support member 13 can be simplified, and the cost of the display device 1 can be reduced.

[0095] Optionally, such as Figure 1 and Figure 7 As shown, the display device 1 also includes a display panel 40 and a second flexible circuit board 50. The display panel 40 is disposed on one side of the light-emitting surface 10a of the backlight module 10. The second flexible circuit board 50 connects the display panel 40 and the printed circuit board 20. The connector 30 is disposed on the side of the printed circuit board 20 away from the light-emitting surface 10a of the backlight module 10, and the second flexible circuit board 50 is located on the surface of the printed circuit board 20 away from the connector 30.

[0096] The display panel 40 can be an LCD panel, which is a non-self-emissive panel and requires a backlight source provided by the backlight module 10.

[0097] The display panel 40 includes a display area and a non-display area disposed around the display area. The display area may have multiple sub-pixels, which may include red sub-pixels, green sub-pixels, and blue sub-pixels, thereby achieving color display. The non-display area may have driving circuits, such as gate driving circuits, which can provide driving signals to the sub-pixels.

[0098] like Figure 7 As shown, the display panel 40 includes a first substrate 41 and a second substrate 42 facing each other, and a liquid crystal layer (not shown) disposed between the first substrate 41 and the second substrate 42. The first substrate 41 is disposed on the side of the second substrate 42 away from the backlight module 10. A first polarizer 43 is disposed on the surface of the first substrate 41 away from the second substrate 42, and a second polarizer 44 is disposed on the surface of the second substrate 42 away from the first substrate 41.

[0099] Light emitted from the backlight module 10 enters the display panel 40. The liquid crystal molecules in the liquid crystal layer of the display panel 40 are deflected under the action of the electric field. The light transmittance of liquid crystal molecules with different deflection angles is different, thereby controlling the light transmittance of the display panel 40 and realizing the control of the brightness of the displayed image.

[0100] like Figure 1 As shown, the second flexible circuit board 50 connects the display panel 40 and the printed circuit board 20. For example, the second flexible circuit board 50 is bonded to the display panel 40 and to the printed circuit board 20.

[0101] like Figure 1 , Figure 2 and Figure 7 As shown, connector 30 is disposed on the side of printed circuit board 20 opposite to the light-emitting surface 10a of backlight module 10, and second flexible circuit board 50 is located on the side surface of printed circuit board 20 opposite to connector 30. That is to say, connector 30 and second flexible circuit board 50 are disposed on different surfaces of printed circuit board 20. Taking the light-emitting surface 10a of backlight module 10 as the front and the side surface opposite to the light-emitting surface 10a of backlight module 10 as the back, connector 30 is located on the back of printed circuit board 20, and second flexible circuit board 50 is located on the front of printed circuit board 20.

[0102] The circuit formed by the printed circuit board 20 and the components is electrically connected to the display panel 40 through the second flexible circuit board 50, providing drive signals to the display panel 40 to drive the display panel 40 to display.

[0103] In some embodiments, such as Figure 1As shown, the display panel 40 is also provided with a driver chip 45. The driver chip 45 can be disposed on the surface of the second substrate 42 near the first substrate 41, and the driver chip 45 can be bonded to the second substrate 42.

[0104] It should be noted that the display area of ​​the display panel 40 can display images, while the non-display area cannot. The bezel of the display device 1 refers to the width from the boundary of the display area to the boundary of the display device 1. Since the printed circuit board 20 is located on one side of the backlight body 11, the bezel width on the side of the display device 1 where the printed circuit board 20 is located is greater than the bezel width on the other three sides. For example... Figure 1 As shown, the display device 1 includes four bezels, wherein the left, top, and right bezels do not have printed circuit boards 20, while the bottom bezel has a printed circuit board 20. The width of the left bezel and the width of the right bezel are both dimensions in the first direction D1, and the width of the top bezel and the width of the bottom bezel are both dimensions in the second direction D2.

[0105] like Figure 1 As shown, the width of the bottom bezel is greater than the width of any other side bezel. By reducing the length s2 of the printed circuit board 20 in the second direction D2, the width of the bottom bezel of the display device 1 can be reduced.

[0106] In this embodiment, the display device 1 can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.
