Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a display apparatus. Background Art

[0002] A display device typically includes a panel, a source driver board (S-board), and a backlight module. The S-board is connected to the panel via a chip-on-film (COF) to provide the panel with a driving circuit. In the prior art, a bracket is required to secure the S-board to the backplane to ensure that the S-board and COF remain in the correct position and prevent damage from vibration or drops. The assembly between the bracket and the backplane typically involves the following two scenarios:

[0003] 1. The S-board is clamped and fixed on the inclined surface on the ground side of the backplane. Since the backplane is provided with a clamping structure, this requires more structural characteristics of the backplane. That is, while ensuring the normal use of the backplane, the bracket can be stably fixed on the backplane and facilitate the installation of the S-board. Due to the structural requirements of the backplane, this bracket fixing method results in a low degree of universality for different types of backplanes.

[0004] 2. The bracket is bonded to the back panel through an adhesive structure. If the adhesive strength of the adhesive structure is too high, it will be difficult to disassemble the adhesive structure during product maintenance, resulting in inconvenience in maintenance. If the adhesive strength of the adhesive structure is average, the bracket will easily fall off. In addition, the adhesive structure is difficult to clean. After the maintenance is completed, the adhesive structure needs to be rearranged, and the original adhesive structure cannot be reused. Utility Model Content

[0005] In order to solve the above technical problems or at least partially solve the above technical problems, this application provides the following technical solutions:

[0006] An embodiment of the present application provides a display device, comprising: a display panel configured to display an image;

[0007] a source driving board connected to the display panel and configured to drive the display panel;

[0008] A backplane, located on one side of the display panel, wherein the backplane comprises:

[0009] motherboard; and

[0010] A side plate connected to one side of the main plate;

[0011] The side plate and the main plate surface enclose a receiving space, and the receiving space is located on a side of the back plate away from the display panel;

[0012] A bracket, comprising:

[0013] a fixing portion configured to mount the source driving board, at least a portion of the source driving board being located in the accommodation space; and

[0014] A connecting portion is connected to the fixing portion and fixed to the side plate.

[0015] The display device provided by the present application has a bracket arranged on the side panel, and there is no need to arrange a matching structure for the bracket on the main board, thereby reducing the design structure requirements for the main board, making the main board design more flexible, and making the overall structure of the back panel more reasonable, so that the back panel has higher mechanical strength and a more reasonable installation space for accommodating the source component, that is, ensuring the support, fixation and protection of the source component by the back panel, and improving the space utilization on the back panel.

[0016] In some embodiments, wherein, a first connecting structure is provided on the side plate;

[0017] The connecting portion is provided with a slot and a second connecting structure;

[0018] The side plate is inserted into the slot, and the first connecting structure is connected to the second connecting structure so that the bracket is fixed on the side plate.

[0019] In the above technical solution, the setting of the slot increases the connection area between the connecting part and the side plate, thereby ensuring the connection strength between the bracket and the side plate. At the same time, through the cooperation of the first connecting structure and the second connecting structure, the bracket is more firmly fixed on the side plate.

[0020] In some embodiments, the first connecting structure is a first protrusion, the second connecting structure is a matching groove, and the first protrusion is inserted into the matching groove.

[0021] In the above technical solution, the structure of the first protrusion and the matching groove is simple and the space occupied is small, thereby improving the space utilization of the product; in addition, the friction and mechanical interference between the first protrusion and the groove wall of the matching groove can prevent the relative movement of the bracket, ensuring the reliability of the bracket fixation.

[0022] In some embodiments, the first connecting structure is a slot, and the second connecting structure is a buckle, and the buckle is snapped into the slot.

[0023] In the above technical solution, you only need to align the buckle with the slot and push it gently to achieve a firm fixation, which greatly saves the installation time of the bracket. In addition, after the buckle is inserted into the slot, it will be tightly combined with the slot to form a firm connection. This connection method can withstand a certain amount of tension, pressure and torque, ensuring that the bracket will not easily loosen or fall off during use.

[0024] In some embodiments, the side plate is further provided with a second protrusion, and the second protrusion extends along the first direction in which the side plate is inserted into the slot;

[0025] The second protrusion presses against a side surface of the connecting portion arranged along the first direction.

[0026] In the above technical solution, the second protrusion serves to limit the connection portion, thereby preventing the connection portion from shaking relative to the side plate, thereby ensuring the reliability of the bracket fixation.

[0027] In some embodiments, the number of the second protrusions is two, and the two second protrusions are arranged on both sides of the first connecting structure.

[0028] In the above technical solution, a mounting position is formed between the two second protrusions, which facilitates the accurate installation of the connecting part. At the same time, the two second protrusions can further limit the connecting part, thereby further ensuring the reliability of the bracket fixation.

[0029] In some embodiments, the fixing portion includes a support plate and a pressing piece, the support plate is connected to the connecting portion, the support plate extends in a second direction away from the connecting portion, a clamping groove is formed between the support plate and the pressing piece, and the source driving board is clamped in the clamping groove;

[0030] In a third direction perpendicular to the second direction, the width of the support plate is greater than the width of the pressing sheet.

[0031] In the above technical solution, the width requirement for the support plate is such that the support plate has a larger support area, so that the support plate and the pressing sheet cooperate better to fix the source driving board.

[0032] In some embodiments, the mainboard has a groove that is recessed in a direction away from the display panel, the groove forms a boss on a side of the mainboard facing away from the display panel, and the side surface of the boss and the side panel enclose the accommodation space;

[0033] The plastic frame of the display device is connected to the side plate.

[0034] In the above technical solution, there is no need to limit the inclination of the side of the boss to ensure that the accommodation space is large enough to accommodate the bracket. At the same time, in addition to installing the bracket, the side panel can also be connected to the rubber frame, thereby reducing the design structure requirements of the main board, making the main board design more flexible, and making the overall structure of the back panel more reasonable.

[0035] In some embodiments, the back plate further comprises a connecting plate, the connecting plate being connected to one side of the main plate and being located on a side of the back plate adjacent to the display panel, and the connecting plate and the side plate being connected to the same side of the main plate, the connecting plate and the main plate being an integrated structure;

[0036] The plastic frame of the display device is connected to the connecting plate.

[0037] In the above technical solution, the design structure requirements for the mainboard are reduced, making the mainboard design more flexible, thereby making the overall structure of the backplane more reasonable, so that the backplane has higher mechanical strength and a more reasonable installation space to accommodate the source components, that is, ensuring the support, fixation and protection of the source components by the backplane, and improving the space utilization on the backplane.

[0038] In some embodiments, the main board and the side board are an integrated structure.

[0039] In the above technical solution, on the one hand, the connection strength between the main board and the side board is guaranteed, so that the back board has higher mechanical strength and the reliability of the back board is improved. On the other hand, the back board can be made by an integrated molding process, which improves the production efficiency of the back board and thus reduces the production cost of the back board.

[0063] The term "exemplary" is used herein to mean "serving as an example, embodiment, or illustration." Any embodiment described as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0064] In the description of this application, the technical terms "first", "second", "third", etc. are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary and secondary relationship of the indicated technical features.

[0065] In the description of this application, the orientations or positional relationships indicated by technical terms such as "upper", "lower", "inside", "outside", "front", "back", "left", "right", "top", and "bottom" are orientations or positional relationships based on the working state of this application.

For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0067] In the description of the present application, “a plurality of” means two or more (including two), unless otherwise clearly and specifically defined.

[0068] In the description of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, and other dimensions of the integrated device shown in the drawings are merely illustrative and do not constitute any limitation on this application.

[0069] like Figures 1 to 11 As shown, the display device provided in the embodiment of the present application includes: a display panel 10, a source driver board 20, a backplane 30, and a bracket 40. It should be noted that the display device can be a display device such as a liquid crystal display, a liquid crystal display, an liquid crystal television, or a mobile terminal such as a mobile phone, a tablet computer, or a smart photo album.

[0070] The display panel 10 is located on the front side of the display device. The front side of the display panel 10 serves as the display surface, which converts electrical signals into image information to display images. Specifically, the display panel 10 has a plurality of pixel units arranged in an array. Each pixel unit can independently control the transmittance and color of light incident on it by the backlight module, so that the light transmitted by all pixel units constitutes the displayed image. It is understood that the display panel 10 does not emit light itself and relies on the light source provided by the backlight module to achieve brightness display. The backlight module can convert point or linear light sources into a high-brightness and uniform surface light source through the optical film assembly 70. That is, the backlight module can emit light evenly across the entire light-emitting surface, providing the display panel 10 with sufficient brightness and uniform distribution of light, so that the display panel 10 can properly display images. Taking a rectangular display panel 10 as an example, the display panel 10 includes a top side, a bottom side, a left side, and a right side. The top side and the bottom side are opposite, and the left side and the right side are opposite. The top side is connected to one end of the left side and one side of the right side, respectively, and the bottom side is connected to the other end of the left side and the other end of the right side, respectively. The display panel 10 may be a liquid crystal display (HCD) panel 10 , ie, a liquid crystal display using a light emitting diode (HED) as a backlight source.

[0071] The source driver board 20, also referred to as the S-board (S-board for short), is the signal control board for the display panel 10. The source driver board 20 is disposed on the ground side of the display panel 10 and is electrically connected to the display panel 10 via a chip-on-film (COF) 60, providing a drive signal to the display panel 10 to drive the display panel 10. The COF 60 has a U-shaped structure and is disposed around the backplane 30. One end of the COF 60 is electrically connected to the source driver board 20, and the other end is electrically connected to the display panel 10. The source driver board 20 is fixed to the ground side of the backplane 30 via a fixing bracket 40.

[0072] The back plate 30 is disposed on the non-display surface of the display panel 10 and is made of aluminum, iron, aluminum alloy, or iron alloy. The back plate 30 supports and bears loads, supporting and securing the edges of components such as the display panel 10. The back plate 30 also dissipates heat for the light source.

[0073] In a specific embodiment of the present application, the backplate 30 is a component of the backlight module. In addition to the backplate 30, the backlight module also includes an optical film assembly 70 (the optical film assembly 70 includes components such as a backlight plate, a reflector, a light guide plate, and an optical film), a plastic frame 50, and a light source (not shown). The optical film assembly 70 adjusts the light generated by the light source. The edge of the optical film assembly 70 abuts the edge of the backplate 30, that is, the edge of the optical film assembly 70 can be supported by the backplate 30. Its shape and size are adapted to the shape and size of the display device. The plastic frame 50 provides a stable mounting frame for the display panel 10, ensuring that the display panel 10 will not shift or loosen during use. For example, in a liquid crystal display, the plastic frame 50 fixes the display panel 10 in a suitable position by connecting with the backplate 30, the front frame, and other components to prevent the display panel 10 from being damaged by vibration or collision during transportation and use. In addition, the plastic frame 50 can also provide support for the light source, light guide plate, reflector, diffuser, etc., to ensure the brightness uniformity and stability of the backlight module. Backlight modules are divided into direct-lit backlight modules and edge-lit backlight modules according to their structural form.

[0074] like Figures 1 to 11 As shown, in a specific embodiment of the present application, the backplane 30 includes: a main board 31 and a side board 32 .

[0075] The mainboard 31 mainly supports and bears other components of the backlight module.

[0076] The side panel 32 is connected to one side of the main board 31. Specifically, the side panel 32 is disposed on the ground side of the main board 31 and extends away from the display panel 10. That is, the side panel 32 is located on the backlight side of the main board 31. The side panel 32 and the main board 31 define a storage space, which is located on the side of the back panel 30 facing away from the display panel 10.

[0077] The bracket 40 includes a fixing portion 41 and a connecting portion 42 .

[0078] The fixing portion 41 is configured to mount the source driving board 20 , and at least a portion of the source driving board 20 is located in the accommodation space.

[0079] The connecting portion 42 is connected to the fixing portion 41 and fixed on the side plate 32 .

[0080] In the prior art, the source driver board 20 is used to provide a driving circuit for the display panel 10. It is an important assembly part of the display device. It is usually necessary to fix the source driver board 20 to the backlight side of the back panel 30 through a bracket 40. Since the bracket 40 is fixed on the back panel 30, this requires more requirements on the structural characteristics of the back panel 30, that is, while ensuring the normal use of the back panel 30, the bracket 40 can be stably fixed on the back panel 30 and facilitate the installation of the source driver board 20; due to the structural requirements for the back panel 30, this type of fixing method of the bracket 40 results in a low degree of universality of the bracket 40 for different types of back panels 30. In the display device provided by the present application, the bracket 40 is arranged on the side panel 32, and there is no need to arrange a matching structure for the bracket 40 on the main board 31, thereby reducing the design structure requirements for the main board 31, making the design of the main board 31 more flexible, and making the overall structure of the back panel 30 more reasonable, so that the back panel 30 has higher mechanical strength and a more reasonable installation space for accommodating the source components, that is, ensuring the support, fixation and protection of the source components by the back panel 30, and improving the space utilization on the back panel 30.

[0081] like Figures 1 to 11 As shown, in one embodiment of the present application, a first connecting structure 321 is provided on the side plate 32 .

[0082] The connecting portion 42 is provided with a slot 421 and a second connecting structure 422 .

[0083] The side plate 32 is inserted into the slot 421 , and the first connecting structure 321 is connected to the second connecting structure 422 , so that the bracket 40 is fixed on the side plate 32 .

[0084] There are generally two ways to fix the bracket: 1. The bracket is fixed on the backplane through the connecting structure. Since the connecting structure is arranged on the backplane, this requires more requirements on the structural characteristics of the backplane, that is, while ensuring the normal use of the backplane, the bracket can be stably fixed on the backplane and facilitate the installation of the source driver board. Due to the structural requirements of the backplane, this type of bracket fixing method leads to a low degree of universality of the bracket for different types of backplanes; 2. The bracket is bonded to the backplane through an adhesive structure. If the adhesive strength of the adhesive structure is large, the adhesive structure is difficult to disassemble during maintenance, resulting in inconvenience in maintenance. If the adhesive strength of the adhesive structure is average, the bracket is easy to fall off. In addition, the adhesive structure is difficult to clean. After the maintenance is completed, the adhesive structure needs to be rearranged, and the original adhesive structure cannot be reused.

[0085] In the embodiment provided by the present application, the first connecting structure 321 is arranged on the side panel 32, which reduces the design structural requirements for the main board 31, makes the design of the main board 31 more flexible, and thus makes the overall structure of the back panel 30 more reasonable, so that the back panel 30 has higher mechanical strength and more reasonable installation space for accommodating source components (source components refer to: components that enable the backlight module to realize its function), that is, ensures that the back panel 30 supports, fixes and protects the source components, and improves the space utilization on the back panel 30.

[0086] In addition, the first connecting structure 321 and the second connecting structure 422 have simple structures, are easy to assemble and disassemble, and can be reused, thereby improving the versatility of the bracket 40.

[0087] In addition, the setting of the slot 421 increases the connection area between the connecting portion 42 and the side panel 32, thereby ensuring the connection strength between the bracket 40 and the side panel 32. At the same time, through the cooperation between the first connecting structure 321 and the second connecting structure 422, the bracket 40 is more firmly fixed on the side panel 32.

[0088] like Figures 1 to 7 As shown, in one embodiment of the present application, the first connection structure 321 is a first protrusion, and the second connection structure 422 is a matching groove, and the first protrusion is inserted into the matching groove.

[0089] In the above technical solution, the structure of the first protrusion and the matching groove is simple and the space occupied is small, thereby improving the space utilization of the product; in addition, the friction and mechanical interference between the first protrusion and the groove wall of the matching groove can prevent the relative movement of the bracket 40, ensuring the reliability of the fixation of the bracket 40.

[0090] like Figures 8 to 10 As shown, in one embodiment of the present application, the first connection structure 321 is a slot, and the second connection structure 422 is a buckle, which is snapped into the slot.

[0091] In the above technical solution, you only need to align the buckle with the slot and push it gently to achieve a firm fixation, which greatly saves the installation time of the bracket 40. In addition, after the buckle is inserted into the slot, it will be tightly combined with the slot to form a firm connection. This connection method can withstand a certain amount of tension, pressure and torque, ensuring that the bracket 40 will not easily loosen or fall off during use.

[0092] Those skilled in the art should understand that, in addition to the above structures, any structures other than the above structures may be used for the first connecting structure 321 and the second connecting structure 422 as long as they can meet the requirements of simple structure and easy assembly and disassembly, and they are not listed here one by one.

[0093] like Figure 7 As shown, in one embodiment of the present application, a second protrusion 322 is further provided on the side plate 32 , and the second protrusion 322 extends along the first direction F1 in which the side plate 32 is inserted into the slot 421 .

[0094] The second protrusion 322 presses against a side surface of the connecting portion 42 arranged along the first direction F1 .

[0095] In order to facilitate the disassembly and assembly of the first connecting structure 321 and the second connecting structure 422, there is a clearance fit between the first connecting structure 321 and the second connecting structure 422, which causes the bracket 40 to shake relative to the side plate 32, increasing the probability of the source driving board 20 installed on the bracket 40 being damaged as the product vibrates. In the above technical solution, the second protrusion 322 works together with the first connecting structure 321 or the second connecting structure 422 to make part of the first connecting structure 321 or the second connecting structure 422 tightly attached. At the same time, since the second protrusion 322 is tightly attached to one side of the connecting portion 42, that is, the second protrusion 322 and the first connecting structure 321 or the second connecting structure 422 jointly clamp part of the connecting portion 42, thereby fixing the bracket 40 relative to the side plate 32, preventing the connecting portion 42 from shaking relative to the side plate 32, thereby ensuring the reliability of the fixation of the bracket 40.

[0096] In a specific embodiment of the present application, the number of the second protrusions 322 is two, and the two second protrusions 322 are arranged on both sides of the first connection structure 321 .

[0097] In the above technical solution, an installation position is formed between the two second protrusions 322, which facilitates the accurate installation of the connecting part 42. At the same time, the two second protrusions 322 can further limit the connecting part 42, thereby further ensuring the reliability of the fixation of the bracket 40.

[0098] like Figure 6 and Figure 10As shown, in one embodiment of the present application, the fixing portion 41 includes a support plate 411 and a pressing piece 412. The support plate 411 is connected to the connecting portion 42. The support plate 411 extends along a second direction F2 away from the connecting portion 42. A snap-fit ​​groove is formed between the support plate 411 and the pressing piece 412, and the source driving board 20 is snapped into the snap-fit ​​groove.

[0099] The free end of the pressing piece 412 (the end where the pressing piece 412 is connected to the support plate 411 is the connecting end, and the end of the pressing piece 412 opposite the connecting end is the free end) is tilted upward to form a guide flange 414, and a guide gap is formed between the guide flange 414 and the support plate 411. During assembly, the source driver board 20 is slid through the guide flange 414 into the guide gap between the pressing piece 412 and the support plate 411, and then inserted into the engaging slot through the guide gap, so that the source driver board 20 is engaged in the engaging slot. In a specific embodiment of the present application, in the second direction F2, the length of the source driving board 20 is H1; in the second direction F2, the length from one end of the source driving board 20 to the position where the source driving board 20 and the pressing piece 412 are pressed is H2; the source driving board 20 and the fixing portion 41 satisfy the following relationship: H2≤(2 / 3)H1. The above-mentioned limitation on the pressing position between the pressing piece 412 and the source driving board 20 can ensure that the pressing piece 412 effectively presses and fixes the source driving board 20.

[0100] like Figure 6 As shown, in the third direction F3 perpendicular to the second direction F2 , the width D1 of the support plate 411 is greater than the width D2 of the pressing piece 412 .

[0101] In the above technical solution, the width requirement for the support plate 411 enables the support plate 411 to have a larger supporting area, so that the support plate 411 and the pressing piece 412 cooperate better to fix the source driving board 20 .

[0102] like Figure 3 and Figure 6 As shown, in another embodiment of the present application, a support platform 413 is provided at one end of the support plate 411 connected to the connecting portion 42. The support platform 413 and the pressing piece 412 are located on the same plate surface of the support plate 411. A placement area for accommodating the source drive board 20 is formed between the pressing piece 412 and the support platform 413. The shape and size of the placement area are adapted to the source drive board 20. Specifically, after the product is assembled, one end of the source drive board 20 along the third direction F3 is inserted into the slot 421, and the other end of the source drive board 20 along the third direction F3 rests on the support platform 413, thereby achieving a snap-fit ​​fit between the source drive board 20 and the support plate 411, further ensuring the assembly stability of the source drive board 20. In another specific embodiment of the present application, a support groove is provided on the support platform 413, and the other end of the source drive board 20 along the third direction is inserted into the support groove.

[0103] like Figure 10 As shown, in another specific embodiment of the present application, in the third direction F3, the widths of the support plate 411, the pressing piece 412 and the connecting portion 42 are the same. Even if the width of the bracket 40 in the third direction is uniformly set, the bracket 40 of this structure is relatively easy to process and manufacture.

[0104] like Figure 6 and Figure 10 As shown, in one embodiment of the present application, the connecting portion 42 includes two connecting pieces 423 , the interval between the two connecting pieces 423 forms a slot 421 , and the widths of the two connecting pieces 423 in the third direction are the same or different.

[0105] Those skilled in the art should understand that the above structural requirements for the bracket 40 can be freely combined according to specific needs.

[0106] like Figure 5 、 Figure 9 and Figure 11 As shown, in one embodiment of the present application, the main board 31 and the side board 32 are an integrated structure. That is, the side board 32 is formed by bending the side edge of the main board 31.

[0107] In the above technical solution, on the one hand, the connection strength between the main board 31 and the side board 32 is guaranteed, so that the back board 30 has higher mechanical strength and the reliability of the back board 30 is improved. On the other hand, the back board 30 can be made by an integrated molding process, which improves the production efficiency of the back board 30 and thus reduces the production cost of the back board 30.

[0108] The following structural drawings specifically illustrate several embodiments of the back plate 30 .

[0109] Example 1

[0110] like Figures 1 to 3 As shown, in one embodiment of the present application, the main board 31 has a groove 311 that is recessed in a direction away from the display panel 10. The groove 311 forms a boss 312 on the side of the main board 31 facing away from the display panel 10. The side of the boss 312 and the side panel 32 form an accommodating space.

[0111] The display device's plastic frame 50 is connected to the side panel 32 .

[0112] In another specific embodiment of the present application, the fixing portion 41 is arranged obliquely relative to the connecting portion 42 , and in the first direction F1 , the height of the fixing portion 41 does not exceed the height of the boss 312 .

[0113] In the above technical solution, there is no need to limit the inclination of the side of the boss 312 to ensure that the accommodation space is large enough to accommodate the bracket 40. At the same time, in addition to installing the bracket 40, the side panel 32 can also be connected to the plastic frame 50, thereby reducing the design and structural requirements of the main board 31, making the design of the main board 31 more flexible, and making the overall structure of the back panel 30 more reasonable.

[0114] Example 2

[0115] like Figure 11 As shown, the back panel 30 also includes a connecting plate 33, which is connected to one side of the main board 31 and is located on the side of the back panel 30 adjacent to the display panel 10, and the connecting plate 33 and the side plate 32 are connected to the same side of the main board 31, and the connecting plate 33 and the main board 31 are an integrated structure.

[0116] The plastic frame 50 of the display device is connected to the connecting plate 33 .

[0117] In another specific embodiment of the present application, the main board 31 and the side board 32 are an integrated structure, that is, the connecting board 33 and the side board 32 are formed by bending the side edges of the main board 31 in two opposite directions.

[0118] In the above technical solution, the design structure requirements for the main board 31 are reduced, making the design of the main board 31 more flexible, thereby making the overall structure of the back panel 30 more reasonable, so that the back panel 30 has higher mechanical strength and a more reasonable installation space to accommodate the source components, that is, ensuring the support, fixation and protection of the source components by the back panel 30, and improving the space utilization on the back panel 30.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
