[0074] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0075] Taking a television as an example, an adapter bracket is generally provided on the display body, and the base is fixedly connected to the adapter bracket by screws. During installation, a screwdriver needs to be used to fix the screws, which has low installation efficiency and inconvenient maintenance. The installation of the adapter bracket increases the cost of the television. To solve the above problems, the present application proposes a display device.

[0076] For ease of description and understanding, the state of the display device when placed upright for use is used as a reference, the vertical direction is the up and down direction, the direction facing the user is the front, the direction facing away from the user is the rear, and the width direction of the display device is the left and right direction.

[0077] Figure 1 A schematic diagram showing the structure of the front side of a display device according to some embodiments is shown; Figure 2 A schematic structural diagram of the back side of a display device according to some embodiments is shown.

[0078] See also Figure 1 and Figure 2 This embodiment provides a display device. The display device may include a display panel 10, and the display panel 10 is used to display images for users to watch. The display panel 10 may be a liquid crystal display panel 10.

[0079] In some embodiments, the display device may include a light source and an optical film (not shown in the figure). The light source, the optical film and the display panel 10 are arranged in sequence from the back to the front. The light emitted by the light source passes through the optical film and is projected onto the display panel 10. After passing through the display panel 10, the image information is displayed on the display panel 10. The display panel 10 is located in front of the optical film, and the light in the optical film is transmitted forward to the display panel 10. The liquid crystal molecules in the display panel 10 are deflected by the electric field stimulation, reducing the pass rate of the light emitted from the optical film to the display panel 10, and then the light is projected into filters of different colors to form an image.

[0080] In some embodiments, the light source is used to emit light. The light source and the optical film can be arranged in parallel. The light source can be located at the light incident side behind the optical film to emit light to the optical film.

[0081] In some embodiments, the display device may include a back plate 20. The back plate 20 is the main support member of the display device, and is disposed vertically on the back side of the display panel 10. A frame protruding forward is formed on the peripheral edge of the back plate 20. The frame is disposed circumferentially and extends around the edge of the back plate 20. The frame extends forward beyond the front side of the back plate 20, and the frame and the back plate 20 enclose a chamber with an opening on the front side for installing a light source and an optical film.

[0082] In some embodiments, the display device may include a back cover 30. The back cover 30 covers the back of the back plate 20, and the back of the back plate 20 and the back of the back plate 20 enclose a mounting cavity 300. A mainboard, a power board, and other driving components may be disposed in the mounting cavity 300. The mainboard, the power board, and other driving components are located within the enclosure of the back cover 30, so that they are protected by the back cover 30.

[0083] In some embodiments, the mainboard is mainly used to operate the control system of the display device and output relevant operation instructions accordingly. The mainboard has a large number of electronic components, which mainly transmit the operation instructions output by the mainboard to the corresponding operation terminal. The power board is separately set or integrated on the mainboard and fixed on the back of the backboard 20. It is mainly used to provide a driving voltage or a stable working voltage to the mainboard and keep the output current stable when the circuit on the mainboard is working.

[0084] In some embodiments, the display device may include a base 40. The display device is supported on a desktop or the ground through the base 40. The base 40 may include a base 400, which is disposed on the bottom side of the rear cover 30, and the base 400 contacts the desktop or the ground to play a supporting role. The base 40 may also include a leg 410, which is connected to the base 400, and the leg 410 extends vertically so as to be connected to the rear cover 30 or the back plate 20, so that the base 400 can support the back plate 20 or the rear cover 30.

[0085] In some embodiments, the seat body 400 can extend in the front-to-back direction to form a flat plate shape, thereby increasing the contact area with the desktop or the ground and being more stable when supported.

[0086] In some embodiments, two bases 40 may be provided at intervals along the width direction of the display device. By providing two bases 40 , the display device can be supported more stably and not easily tipped over.

[0087] Figure 3 shows a schematic diagram of the structure of a display device after a back cover is hidden according to some embodiments, Figure 4A schematic diagram of the back side of a display device after a back cover is hidden according to some embodiments is shown. Figure 5 An example is shown Figure 4 Sectional view along the AA direction, Figure 6 An example is shown Figure 5 A partial enlarged view of point B in the middle.

[0088] Continue to see Figures 3 to 11 In some embodiments, a fence 200 may be provided on the back of the back plate 20. The fence 200 and the back of the back plate 20 are combined to form a limiting channel 210, which extends in the vertical direction. The upper and lower ends of the limiting channel 210 are open to facilitate the insertion and connection of the legs 410. Among them, a avoidance hole may be opened at the bottom end of the rear cover 30, and the avoidance hole corresponds to the opening of the limiting channel 210. In this way, when the base 40 is installed, the legs 410 extend into the limiting channel 210 from the avoidance hole. The limiting channel 210 guides the legs 410 during the installation and removal stages. After the installation is completed, the limiting channel 210 surrounds the legs 410 therein, and limits the legs 410 in the circumferential direction.

[0089] In some embodiments, the back cover 30 may include a cover plate 310 and a bottom plate 320. The cover plate 310 and the back of the back plate 20 are arranged opposite to each other, the cover plate 310 extends in the vertical direction, one end of the bottom plate 320 is connected to the bottom of the cover plate 310, and the other end of the bottom plate 320 is connected to the bottom of the back plate 20, so that the bottom plate 320, the cover plate 310 and the back plate 20 are surrounded to form the above-mentioned installation cavity. Among them, the avoidance hole 330 is opened on the bottom plate 320, and the bottom plate 320 can extend in the horizontal direction.

[0090] In some embodiments, the back cover 30 may further include a side panel, one end of which is connected to the side and top of the cover plate 310, and the other end of which is connected to the back plate 20, so that the installation cavity is closed and the structure of the back cover 30 is more complete.

[0091] In some embodiments, the portion of the leg 410 extending into the limiting channel 210 can be snap-fitted to the inner wall of the limiting channel 210, thereby facilitating the fixing of the limiting leg 410. The snap-fit ​​connection method can make it more convenient to install and disassemble the base 40, and facilitate assembly and maintenance.

[0092] In some embodiments, a slot 411 may be provided on the side wall of the leg 410 extending into the limiting channel 210. The length direction of the slot 411 intersects with the vertical direction, and the length direction of the slot 411 may have a certain angle with the vertical direction, such as the length direction of the slot 411 may be perpendicular to the vertical direction, that is, extend in the horizontal direction.

[0093] In some embodiments, a buckle 211 is provided on the inner wall of the limiting channel 210 at a position corresponding to the slot 411, and the buckle 211 is engaged in the slot 411, thereby realizing a snap connection between the leg 410 and the inner wall of the limiting channel 210 to limit the vertical movement of the leg 410. By engaging the buckle 211 in the slot 411, the leg 410 is vertically limited after being extended into the limiting channel 210. At the same time, when disassembly is required, the leg 410 can be directly dragged downward to disengage the buckle 211 from the slot 411, which makes disassembly more convenient.

[0094] In some embodiments, when the length direction of the card slot 411 is perpendicular to the vertical direction, the card slot 411 can have a greater limiting effect on the buckle 211 in the vertical direction, the support leg 410 and the limiting channel 210 are more tightly engaged, and the connection is more stable.

[0095] In some embodiments, at least two buckles 211 may be arranged at intervals in the horizontal direction, and at least two buckles 211 may be inserted into the slots 411 to improve the connection strength between the legs 410 and the enclosure 200, so that the legs 410 are more tightly engaged in the limiting channel 210. Three, four or five buckles 211 may also be arranged. In this embodiment, two buckles 211 are arranged at intervals.

[0096] In some embodiments, the slot 411 may also be opened on the inner wall of the limiting channel 210 , and correspondingly, the buckle 211 is arranged on the portion of the leg 410 extending into the limiting channel 210 .

[0097] In some embodiments, the enclosure 200 may include a bottom wall 203. The bottom wall 203 is opposite to the back of the back plate 20 and extends in the vertical direction. The enclosure 200 may also include side walls 204 connected to both sides of the bottom wall 203, and the two side walls 204 are connected to the back of the back plate 20, and the bottom wall 203 and the two side walls 204 form a semi-enclosed structure with one end open. The enclosure 200 and the back of the back plate 20 are enclosed to form a limiting channel 210, and the upper and lower ends of the limiting channel 210 are open.

[0098] In some embodiments, the buckle 211 is disposed on the bottom wall 203 , so that the buckle 211 can be formed by the structure of the enclosure 200 , such as the bottom wall 203 of the enclosure 200 is stamped toward the back plate 20 , so that part of the structure protrudes toward the back plate 20 to form the buckle 211 .

[0099] In some embodiments, the buckle 211 can be disposed on the top of the bottom wall 203. In this way, when the leg 410 is inserted into the limiting channel 210 from the avoidance hole, the slot 411 on the leg 410 will finally engage with the buckle 211 to achieve a limiting connection between the two, thereby reducing the difficulty of installing the leg 410.

[0100] Figure 7The structure diagram of the backplane according to some embodiments is exemplarily shown. Figure 8 An example is shown Figure 7 A partial enlarged view of point C in the middle. Fig. 9 The schematic diagram of the structure of a base in a display device according to some embodiments is exemplarily shown.

[0101] Continue to see Figures 7 to 9 In some embodiments, the bottom wall 203 may be provided with two sides of the buckle 211 in the horizontal direction with a break 205, and the break 205 may extend to the top of the bottom wall. By providing the break 205, the part of the bottom wall 203 where the buckle 211 is located can have the ability of elastic deformation, and when it is connected with the side wall 204 of the leg 410, it can be slightly deformed to the rear side, so that the leg 410 can pass upward, and when the slot 411 moves to align with the buckle 211, the part of the bottom wall structure recovers the deformation forward, so that the buckle 211 is stuck in the slot 411, so that the leg 410 and the enclosure 200 are firmly connected.

[0102] In some embodiments, when two or more buckles 211 are provided, the two break openings 205 are located on both sides of all the buckles 211 .

[0103] In some embodiments, the buckle 211 may also be disposed at the bottom of the bottom wall, and correspondingly, the break 205 extends to the bottom end of the bottom wall.

[0104] In some embodiments, a plurality of structural reinforcement portions 250 may be provided along the vertical direction at the junction of the outer side surface of the side wall 204 of the enclosure and the back surface of the back plate 20, thereby enhancing the connection strength between the enclosure 200 and the back plate 20, thereby enhancing the stability of the support legs 410 installed in the limiting channel 210, and preventing the enclosure 200 from being separated from the back plate 20 due to the force of the support legs 410.

[0105] In some embodiments, the plurality of structural reinforcement parts 250 can be connected to form a reinforcing rib structure, or can be formed independently. The structural reinforcement part 250 itself can be a convex block structure connected to the junction of the outer side surface of the enclosure side wall 204 and the back surface of the back plate 20.

[0106] In some embodiments, a punching hole may be formed on the back plate 20 at a position corresponding to the enclosure 200. The two side walls 204 of the enclosure 200 are respectively formed by punching the two opposite hole walls of the punching hole. During molding, the back plate 20 may be punched from the front to the rear through a punching process, thereby forming the punching hole and the enclosure 200, so that the enclosure 200 and the back plate 20 are an integrated structure, the molding process is simpler, and the connection strength between the enclosure 200 and the back plate 20 is also higher.

[0107] In some embodiments, the back of the back plate 20 is stamped to form the enclosure 200 through a stamping process, which can make the enclosure 200 easier to form and have a greater structural strength. The back plate 20 can be made of galvanized steel plate, which has better structural strength.

[0108] In some embodiments, a light shielding member 240 may be provided at the inner side of the back plate 20 corresponding to the punching hole, and the light shielding member 240 is used to shield the punching hole to prevent foreign matter from entering and light leakage when the legs 410 are installed. The light shielding member 240 may be a black light shielding tape covering the punching hole.

[0109] In some embodiments, a partition 260 may be provided in the punching hole. The partition 260 separates the punching hole in the vertical direction to form an independent first punching hole 220 and a second punching hole 230. The partition 260 may be a part of the back plate. The first punching hole 220 and the second punching hole 230 are formed by punching two different parts of the back plate 20 in the vertical direction. The connecting part between the first punching hole 220 and the second punching hole 230 on the back plate 20 constitutes the partition 260.

[0110] In some embodiments, the enclosure 200 may include a first portion 201 and a second portion 202 spaced apart in the vertical direction. The first portion 201 and the second portion 202 both include corresponding bottom walls and side walls 204, so that the first portion 201 and the back of the back plate 20 enclose a first channel, and the second portion 202 and the back of the back plate 20 enclose a second channel. The first channel and the second channel constitute a limiting channel 210.

[0111] The first part 201 can be formed by stamping the hole wall of the first punching hole 220. The second part 202 can be formed by stamping the hole wall of the second punching hole 230. During molding, the back plate 20 can be stamped from the front to the back, so that the first punching hole 220 and the first part 201, as well as the second punching hole 230 and the second part 202 are formed at the same time. The first part 201, the second part 202 and the back plate 20 are integrally formed, the structural strength is higher, and the molding process is simpler.

[0112] By dividing the enclosure 200 into the first part 201 and the second part 202, when the installation starts, the first channel formed by the first part 201 first guides the legs 410, and the second channel can be longer than the first channel. The second channel plays a major role in connection and limiting, and the legs 410 extend into the first channel and the second channel from the avoidance hole in sequence. In this way, when the enclosure 200 is formed independently of the back plate 20, the length of the enclosure 200 can be saved, thereby reducing costs. Among them, the buckle 211 is set on the bottom wall of the second part 202, and the legs 410 will not engage with the buckle 211 until they extend into the second part 202.

[0113] In some embodiments, the first punching hole 220 and the second punching hole 230 are separated by a partition 260, and a large punching hole can be divided into two small first punching holes 220 and second punching holes 230, so that the partition 260 has a certain blocking effect on the support leg 410 extending into the inner side of the back plate 20. During assembly, if the support leg 410 is tilted forward at a certain angle to be inserted into the avoidance hole, it can be blocked by the partition 260, which plays a certain anti-misoperation role and prevents the assembler from operating incorrectly.

[0114] In some embodiments, to prevent the assembler from misoperating, after the leg 410 is inserted into the first channel, it extends from the first punching hole 220 into the inner side of the back plate 20. The vertical length of the first punching hole 220 can be limited to ensure that the assembler will not continue to extend into the first punching hole 220 even after inserting the leg 410 into the first channel at the maximum insertion angle. The maximum insertion angle refers to the maximum angle at which the assembler can tilt the leg 410 toward the front side after inserting the leg 410 into the avoidance hole 330. The insertion angle of the assembler is verified through multiple tests. In different scenarios, the maximum insertion angle can vary.

[0115] See also Fig.12 In some embodiments, the vertical length of the first punching hole 220 is set to L, and L is configured as: when the leg 410 is inserted into the first channel at the maximum insertion angle and the leg 410 abuts against the bottom wall of the first part 201, L≤H1 / tanα, wherein H1 is the length of the first channel in the front-to-back direction, and α is the maximum insertion angle of the leg 410.

[0116] It can be understood that, after the leg 410 is extended into the first channel, the leg 410 abuts against the bottom wall of the first part 201, and there is still a certain gap between the leg 410 and the end of the avoidance hole 330 away from the back plate 20, but limited by the bottom wall of the first part 201, the leg 410 can no longer tilt toward the front side, and the angle at which the leg 410 tilts toward the front side is its maximum insertion angle. In this scenario, by limiting L≤H1 / tanα, that is, when L=H1 / tanα, the front end of the leg 410 just abuts against the top of the first punching hole 220 and will not extend into the first punching hole 220. If the length of L is reduced, the front end of the leg 410 will exceed the top of the first punching hole 220 in the vertical direction, and will not extend into the first punching hole 220, thereby ensuring that in this scenario, the leg 410 will not extend from the first punching hole 220 into the inner side of the back plate 20.

[0117] See also Fig.13In some embodiments, the vertical length of the first punching hole 220 is set to L, and L is configured as: when the leg 410 is inserted into the first channel at the maximum insertion angle and the leg 410 abuts against the hole wall of the avoidance hole 330 on the side away from the back plate 20, L+L1≤H2 / tanα, wherein L1 is the distance from the bottom end of the first punching hole 220 to the bottom plate 320, H2 is the vertical distance from the end of the avoidance hole 330 away from the back plate 20 to the back plate 20, and α is the maximum insertion angle of the leg 410.

[0118] It can be understood that, after the leg 410 extends into the first channel, the leg 410 abuts against the hole wall of the avoidance hole 330 away from the back plate 20, and there is still a certain gap between the leg 410 and the bottom wall of the first part 201, but the leg 410 can no longer tilt forward due to the hole wall of the avoidance hole 330. At this time, the angle at which the leg 410 tilts toward the front side is its maximum insertion angle. In this scenario, by limiting L+L1≤H2 / tanα, that is, when L+L1=H2 / tanα, the front end of the leg 410 just abuts against the top of the first punching hole 220 and will not extend into the first punching hole 220. If the length of L or L1 is reduced, the front end of the leg 410 will exceed the top of the first punching hole 220 in the vertical direction, and will not extend into the first punching hole 220, thereby ensuring that in this scenario, the leg 410 will not extend from the first punching hole 220 into the inner side of the back plate 20.

[0119] In some embodiments, a first chamfer 415 can be formed on the side of the top end of the leg 410 facing the back side of the back panel 20 and the bottom wall of the enclosure 200. By forming the first chamfer 415, the top end of the leg 410 facing the back side of the back panel 20 and the bottom wall of the enclosure 200 can be more easily inserted, thereby improving assembly efficiency.

[0120] In some embodiments, a second chamfer 416 is formed on the side of the top of the leg 410 facing the side wall of the enclosure 200. By forming the second chamfer 416, the top of the leg 410 facing the side wall of the enclosure 200 is easier to extend into, and the first chamfer 415 makes it easier for the leg 410 to extend into the limiting channel 210, thereby improving assembly efficiency. The angles of the first chamfer 415 and the second chamfer 416 can be the same or different, and are set according to actual conditions.

[0121] In some embodiments, the shading member 240 covers the first punching hole 220 and the second punching hole 230 respectively. The shading member 240 is used to shield the first punching hole 220 and the second punching hole 230 to prevent foreign matter from entering and light leakage when the support leg 410 is installed.

[0122] In some embodiments, the leg 410 may include a support portion 412 extending vertically. One end of the support portion 412 is connected to the base body 400, and the support portion 412 may be perpendicular to the base body 400. The leg 410 may also include a limit portion 413 extending vertically, and the other end of the support portion 412 is connected to the limit portion 413, and the cross-sectional area of ​​the limit portion 413 is smaller than the cross-sectional area of ​​the support portion 412, so that the support portion 412 and the limit portion 413 form a stepped structure, and the limit portion 413 extends into the limit channel 210 and is engaged with the limit channel 210 through the buckle 211.

[0123] In some embodiments, the cross-sectional area of ​​the support portion 412 is larger than the cross-sectional area of ​​the limiting channel 210, and the bottom of the enclosure 200 is supported on the support portion 412, and the table surface at the top of the support portion 412 supports and limits the enclosure 200. When the buckle 211 is inserted into the slot 411, the top of the support portion 412 can just abut against the bottom of the enclosure 200.

[0124] In some embodiments, at least a portion of the back surface of the support portion 412 is tilted away from the back plate 20 to form a guide slope 414, which is connected to the inner edge of the avoidance hole. This can prevent the base 40 from being installed in the wrong direction when the legs 410 are inserted. Only when the base 40 is installed in the correct direction can the guide slope 414 finally connect with the inner edge of the avoidance hole. The bottom end of the guide slope 414 can extend to the seat body 400, and the top end of the guide slope 414 can extend to the middle and upper area of ​​the support portion 412.

[0125] In summary, in this embodiment, a barrier 200 is provided on the back side of the back plate 20 to form a limiting channel 210. During installation, the legs 410 of the base 40 extend from the avoidance holes into the limiting channel 210, and are fixed by snap-fitting the legs 410 and the inner walls of the limiting channel 210. During disassembly, the legs 410 can be directly pulled out with force. Compared with the existing display device, the adapter bracket can be eliminated, so that the installation and disassembly of the base 40 are more convenient, the working efficiency is higher, and the cost of the display device can also be reduced.
