Description

Technical Field

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

[0002] In the field of display device technology, taking televisions as an example, with the gradual improvement of optical and structural technologies, more and more ultra-thin LCD TVs are being designed. As television screen sizes increase, the thickness decreases significantly, but the overall mechanical strength of the device also decreases. The back cover of a television is typically made of plastic, and during storage and transportation, localized stress on the back cover can easily lead to inward or outward deformation defects. During operation, large-screen LCD TVs generate a lot of heat due to their high power consumption. The heat source near the power board and motherboard on the back cover is relatively high, making inward deformation more likely. While the temperature is slightly lower at the main gate, residual injection stress can still be released, leading to outward deformation. These inward and outward deformation defects in the back cover cause the LCD TV to fail to meet factory requirements. Utility Model Content

[0003] Therefore, it is necessary to provide a display device that can effectively prevent the back cover from deforming into concave or convex shapes, addressing the shortcomings of existing technologies.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] For ease of description and understanding, the display device is used upright as a reference, with the vertical direction referring to the up and down direction. Figure 1 or Figure 2 As shown by the Z-arrow in the image; the direction facing the user is front, the direction away from the user is back, and the width direction of the display device is the left-right direction, as shown in the image. Figure 1 or Figure 2 As indicated by the X arrow in the diagram. The front side is the side of the display device that displays image information, and the side facing away from the front is the back side. In this application, the front side refers to the front panel.

[0032] See Figure 1 and Figure 2 This embodiment provides a display device, including a back plate 10, which has a front side and a back side disposed opposite to each other. The front side of the back plate 10 is also the front side surface of the back plate 10, and the back side of the back plate 10 is also the rear side surface of the back plate 10.

[0033] For example, the backplate 10 may be a structure made of a metallic material, such as iron, copper, or aluminum alloy. By using a metallic backplate 10, the structural strength of the backplate 10 is maintained while allowing for a thinner design, thus enabling the display device to be designed more slenderly. Of course, the backplate 10 may also be made of a non-metallic material, and structural strength requirements may be met, for example, by increasing the thickness of the backplate 10 itself.

[0034] For example, the display device also includes a display panel. The display panel is mounted on the front of the back panel 10.

[0035] For example, the display device also includes a rear housing 20. The rear housing 20 is mounted on the back side of the back panel 10. A cavity 30 is formed between the rear housing 20 and the back panel 10. Optionally, the periphery of the rear housing 20 protrudes toward and connects to the back panel 10, or a first frame connects the periphery of the rear housing 20 and the back side of the back panel 10. In this way, a gap is provided between the rear housing 20 and the back panel 10, forming the cavity 30.

[0036] The display device includes, but is not limited to, a television or a computer monitor. The following explanation will use a television as an example.

[0037] For example, the display device also includes a light source and an optical film assembly. The back panel 10, the light source, the optical film assembly, and the display panel are arranged sequentially from back to front. The light emitted by the light source is projected onto the display panel after passing through the optical film assembly, and image information is displayed on the display panel after being processed by the display panel. The front side of the display panel is the display surface.

[0038] The back panel 10 serves as the main support for the display device. When the display device is in normal use, the back panel 10 is positioned vertically. A second frame protruding forward is formed along the peripheral edge of the back panel 10. The second frame is circumferentially arranged and extends around the edge of the back panel 10. The second frame protrudes forward from the front side of the back panel 10, and the second frame and the back panel 10 together form a mounting cavity with a front opening for mounting the backlight and optical film assembly. The display panel is fixed to the front end of the second frame.

[0039] The light source is used to emit light. The light source and the optical film group are arranged in parallel. The light source is located on the light-incident side behind the optical film group so as to emit light toward the optical film group. The optical film group is located in front of the backlight so that after the light passes through the optical film group, uniform white light is obtained on the light-emitting side in front of the optical film group.

[0040] Optionally, the backlight source is, for example, an LED light panel, which is attached to the bottom surface of the mounting cavity and emits white light towards the optical film assembly. The backlight source and the optical film assembly are spaced apart along the light emission direction of the light source, forming a light mixing distance. Alternatively, the backlight source and the optical film assembly can be attached to each other along the light emission direction of the light source.

[0041] The optical film assembly is positioned in front of the backlight and spaced apart from it to improve the uniformity and brightness of the light source. Optionally, the optical film assembly includes a diffuser plate and multiple films arranged sequentially. The multiple films may include brightness enhancement plates and multiple prism sheets, or the multiple films may include multiple prism sheets.

[0042] The display panel is located in front of the optical film group. The light from the optical film group is transmitted forward to the display panel. The liquid crystal molecules in the display panel are deflected by the electric field, reducing the transmittance of the light emitted from the optical film group into the liquid crystal panel, and thus projecting the light into filters of different colors to form an image.

[0043] The rear cover 20 is located on the rear side of the back plate 10, and the chamber 30 is formed between the front side of the rear cover 20 and the rear side of the back plate 10. The main board, power board and other driving components are disposed in the chamber 30.

[0044] For example, the display device also includes a motherboard, a power board, and other driving components. The motherboard, power board, and other driving components are all, for example, housed within the cavity 30. The motherboard, power board, and other driving components are located within the enclosure of the rear housing 20 to protect the components within the rear housing 20.

[0045] Please see Figure 3 , Figure 4 and Figure 6 For example, the rear cover 20 is provided with heat dissipation holes 21. The heat generated by the motherboard and power board during operation can be dissipated outward through the heat dissipation holes 21, which has a good heat dissipation effect and can avoid the temperature from being too high and affecting the electrical performance.

[0046] The motherboard is used to perform calculations on the control system of the display device and output relevant operation instructions. The motherboard has numerous electronic components, primarily responsible for transmitting the operation instructions output by the motherboard to the corresponding operating terminals.

[0047] The power supply board is either separately mounted or integrated onto the motherboard and fixed to the back of the backplate 10. The power supply board is electrically connected to the motherboard to provide drive voltage or a stable operating voltage to the motherboard and to maintain a stable output current when the circuits on the motherboard are operating.

[0048] Optionally, other driving components include speakers and power strips, which can be set and adjusted according to actual needs and are not limited here. The speakers are located on the back of the back panel 10 and are mainly used to produce corresponding sounds in conjunction with the interface displayed on the display panel. The power strip has multiple different types of interfaces for connecting external devices to receive or output signals to them. For example, the power strip is integrated on the motherboard. Other driving components can be remote control modules or voice modules, etc.

[0049] As mentioned in the background art, the back cover 20 in the related technology has the problem of inward and outward deformation during storage and transportation or during the operation of the whole machine. Especially when the size of the LCD TV is larger, such as larger than 100 inches or even larger than 150 inches, the back cover 20 is prone to inward and outward deformation.

[0050] In this embodiment, the concave deformation refers to the deformation of the rear shell 20 in the direction closer to the back plate 10; the convex deformation refers to the deformation of the rear shell 20 in the direction away from the back plate 10.

[0051] To reduce the concave-convex deformation of the rear shell 20, for example, the rigidity of the rear shell 20 can be increased to prevent such deformation. Specifically, during molding, the rear shell 20 is filled with filler materials, including but not limited to glass fiber or mineral powder, in the polymer material. These filler materials can increase the rigidity of the rear shell 20. However, the low compatibility between the filler materials and the polymer materials makes injection molding difficult.

[0052] Furthermore, to improve the difficulties in injection molding, plasticizers need to be added to the polymer material. The mechanism of plasticizers is to weaken the van der Waals forces between polymer chains, thereby improving material flowability and aiding filling. However, the reduction in the forces between polymer chains leads to a decrease in the material strength of the back shell 20, which in turn makes the heat dissipation holes 21 of the back shell 20 prone to impact cracking defects. Therefore, the back shell 20, made of a material with high rigidity and reduced strength, still needs to be reinforced through structural design to prevent impact cracking defects at the heat dissipation holes 21 of the back shell 20, but this leads to complex assembly and machine vibration problems.

[0053] Therefore, in order to solve the deformation problem of the rear shell 20, for example, please refer to Figure 2 and Figure 5 The display device in this embodiment includes a frame 40. The frame 40 is disposed within the cavity 30. The rear shell 20 has a mounting portion 22 facing the back plate 10, and the frame 40 is mounted on the mounting portion 22.

[0054] The width of the rear shell 20 is greater than its length in the vertical direction, therefore, the rear shell 20 is prone to deformation defects in the width direction. For example, the frame 40 is elongated and extends along the width direction of the rear shell 20.

[0055] Optionally, the shape of the frame 40 is adapted to the shape of the rear shell 20, and the frame 40 is installed against the inner wall of the rear shell 20 to provide better resistance to deformation. Specifically, when the inner wall of the rear shell 20 is flat, the frame 40 is straight; when the inner wall of the rear shell 20 is curved, the frame 40 is correspondingly curved and has the same curvature as the inner wall of the rear shell 20.

[0056] For example, both the motherboard and power board are offset from the frame 40 along the thickness direction of the rear shell 20. Specifically, the motherboard and power board are completely offset from the frame 40 along the thickness direction of the rear shell 20. That is, the motherboard and power board do not overlap with the frame 40 along the thickness direction of the rear shell 20. In this way, the frame 40 is arranged compactly and reasonably within the cavity 30, without interfering with the motherboard and power board, and without increasing the thickness of the television device due to overlap with the motherboard and power board along the thickness direction of the rear shell 20.

[0057] The aforementioned display device has a mounting part 22 on the part of the back cover 20 facing the back plate 10. The frame 40 is mounted on the back cover 20 through the mounting part 22 and is elongated and extends along the width direction of the back cover 20. This increases the rigidity of the back cover 20 and prevents the back cover 20 from deforming into concave or convex shapes during storage, transportation and use.

[0058] Since the rigidity of the rear shell 20 can be enhanced by the frame 40, the deformation problem can be solved. Therefore, the rear shell 20 can be made of a material with moderate rigidity and high strength, resulting in relatively high structural strength at the heat dissipation hole 21 and preventing impact cracking defects.

[0059] Optionally, the material of the back cover 20 may include, but is not limited to, resin or PC. Furthermore, no fillers such as glass fiber or mineral powder, nor plasticizers, are added during the injection molding of the back cover 20. Therefore, the material of the back cover 20 has high strength, effectively preventing impact deformation and cracking defects at the heat dissipation holes 21.

[0060] Please see Figure 5 For example, the mounting part 22 is provided with a slot 221, and the frame 40 is snapped and fixed in the slot 221. In this way, the frame 40 can be quickly installed into the rear shell 20, which facilitates the assembly operation.

[0061] Of course, as some alternative solutions, the frame 40 can also be fixed to the mounting part 22 by various methods such as bonding, riveting, and screwing, which are not limited here.

[0062] To improve the stability of the frame 40, the mounting part 22 is not limited to one, but can be multiple and arranged at intervals along the extension direction of the frame 40. All mounting parts 22 are connected to the frame 40, so that the frame 40 is stably mounted on the rear shell 20.

[0063] Optionally, the mounting part 22 and the rear shell 20 are integrally injection molded. This allows the mounting part 22 to be integrally formed with the rear shell 20, resulting in higher production efficiency and lower costs. Of course, the mounting part 22 can also be fixed to the rear shell 20 by various methods, including but not limited to bonding, riveting, and screwing, without specific limitations.

[0064] It should be noted that the number of skeletons 40 is, for example, one or more. Among them, multiple can be, for example, two, three, four or any other arbitrary number.

[0065] Please refer to Figure 7 When there is only one skeleton 40, the number of skeletons 40 is small, which can save the cost of the device and improve the assembly efficiency.

[0066] Please refer to Figures 3 to 5 When multiple frames 40 are used, the deformation resistance of the rear shell 20 can be improved compared to a single frame. Optionally, multiple frames 40 are arranged sequentially at intervals along the vertical direction of the rear shell 20. Specifically, multiple frames 40 are arranged at equal intervals along the vertical direction of the rear shell 20, which makes the deformation resistance of various parts of the rear shell 20 more balanced.

[0067] Based on the aforementioned embodiments, in order to satisfy the installation and fixation of multiple skeletons 40 on the rear shell 20, the rear shell 20 is provided with one or more mounting parts 22 corresponding to each skeleton 40, thereby enabling multiple skeletons 40 to be installed and fixed to the rear shell 20.

[0068] Understandably, in order not to affect the heat dissipation of the heat dissipation hole 21, and to avoid overlapping and interfering with the power board and motherboard along the thickness direction of the rear shell 20, for example, when each frame 40 is installed and fixed on the rear shell 20, it is ensured that the heat dissipation hole 21, power board and motherboard, etc. are all staggered with each frame 40 along the thickness direction of the rear shell 20.

[0069] The width of the rear shell 20 is W, and the length of the skeleton 40 is L.

[0070] For example, L / W ≥ 40%, and / or L / W ≤ 80%. Specifically, L / W includes, but is not limited to, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, or 80%. When L / W is less than 40%, the rear shell 20 has weak resistance to deformation and is prone to deformation; when L / W is greater than 80%, material is wasted and costs are high.

[0071] Please see Figure 2 and Figure 5 For example, the frame 40 is provided with a buckle 41. Specifically, the buckle 41 is provided on the side of the frame 40 facing the back plate 10 and protrudes towards the back plate 10. The back plate 10 is provided with a snap-fit ​​portion 11. The snap-fit ​​portion 11 is provided on the side of the back plate 10 facing the rear shell 20. The buckle 41 and the snap-fit ​​portion 11 snap together. In this way, the frame 40 and the back plate 10 are connected by the snap-fit ​​portion 41 and the snap-fit ​​portion 11, which can effectively suppress the outward deformation of the rear shell 20.

[0072] In order to connect with the buckle 41, the snap-fit ​​part 11 may include, but is not limited to, snap-fit ​​holes or snap-fit ​​blocks protruding toward the rear housing 20, as long as they can achieve snap-fit ​​connection with the buckle 41.

[0073] It should be noted that the number of each of the buckle 41 and the snap-fit ​​part 11 can be flexibly adjusted and set according to actual needs, such as one or more, and the number can be the same or the same, without limitation here.

[0074] For example, the latch 41 and the latching part 11 are each one and they latch into each other.

[0075] In order to ensure that the frame 40 and the back plate 10 are connected at multiple locations and the assembly is stable, for example, there are multiple buckles 41 arranged at intervals along the extension direction of the frame 40, and multiple snap-fit ​​parts 11 arranged at intervals along the width direction of the back plate 10.

[0076] Specifically, when the number of latches 41 and the number of engaging parts 11 are different, for example, when the number of latches 41 is greater than the number of engaging parts 11, at least some of the latches 41 are engaged with each of the multiple engaging parts 11 in a one-to-one manner. At least some of the latches 41 abut against the back of the back plate 10, for example. In this way, on the one hand, the latches 41 are engaged with the engaging parts 11 to connect the frame 40 and the back plate 10, which can effectively prevent the rear shell 20 from bulging outward; on the other hand, the latches 41 also abut against the back of the back plate 10, which can effectively prevent the rear shell 20 from bulging inward. In addition, compared with the method of connecting the rear shell 20 and the back plate 10 using multiple screws, the assembly efficiency is greatly improved by simply aligning and engaging each of the first latches 41 on the frame 40 with the engaging parts 11 on the back plate 10.

[0077] Of course, as some optional solutions, the number of buckles 41 and snap-fit ​​parts 11 can be the same. When the number of buckles 41 and snap-fit ​​parts 11 is the same, each buckle 41 and each snap-fit ​​part 11 are respectively snap-fitted. In this way, the connection between the frame 40 and the back plate 10 can be realized, and the back shell 20 can be effectively prevented from bulging outward deformation. In order to prevent the back shell 20 from bulging inward deformation, the frame 40 is further provided with an abutment part, which is provided on the side of the frame 40 facing the back plate 10. For example, there are one or more abutment parts, and the abutment parts abut against the back plate 10. In this way, the abutment parts abut against the back plate 10, which can effectively prevent the back shell 20 from bulging inward deformation.

[0078] It should be noted that the height of the buckle 41 protruding from the outside of the frame 40 can be flexibly adjusted and set according to the distance between the back shell 20 and the back plate 10 and the outer diameter of the frame 40, so as to ensure that the back shell 20 can be properly installed on the back plate 10 and can be engaged with the snap-fit ​​part 11 and abut against the back plate 10.

[0079] Based on the aforementioned embodiments, all the clips 41 are, for example, injection molded onto the frame 40. Of course, the clips 41 can also be fixed to the frame 40 by, for example, adhesive bonding or fasteners such as screws and pins. This is not limited here, and can be flexibly adjusted and set according to actual needs.

[0080] Based on the aforementioned embodiments, the latch 41 is made of a soft material, including but not limited to soft rubber or soft plastic. Thus, the contact between the soft material latch 41 and the hard material backplate 10 is not a hard contact; the soft material acts as an elastic buffer, absorbing resonance signals, effectively preventing sound quality loss, and reducing machine vibration noise and resonance noise generated by the host audio signal.

[0081] Furthermore, the Shore hardness of the snap fastener 41 is ≥70°. Optionally, the Shore hardness of the snap fastener 41 is, for example, 70°, 72°, 73°, 75°, 76°, 78°, 80°, or 85°. In this way, the high Shore hardness of the snap fastener 41 can ensure the stability of the snap-fit ​​part 11 when connected, and provide a greater stable support effect when it abuts against the back plate 10 to prevent the rear shell 20 from concave deformation.

[0082] For example, the Shore hardness of the latch 41 is ≤85°. Thus, when the Shore hardness of the latch 41 is greater than 85°, the hardness of the latch 41 is too large, which will lead to defects such as machine vibration noise and resonance noise defects generated with the host audio signal.

[0083] For example, the skeleton 40 includes a rigid body and a soft covering layer. The soft covering layer is wrapped around the outer wall of the rigid body. In this way, the rigid body can ensure the structural strength of the skeleton 40, while the soft covering layer can prevent the skeleton 40 from making hard contact with the rear shell 20, which would cause noise defects and thus reduce noise.

[0084] Optionally, the rigid body may include, but is not limited to, a metal wire. The metal wire may be, for example, a steel wire or a copper wire.

[0085] Alternatively, the soft wrapping layer and the buckle 41 can be individually formed on the rigid body, or they can be integrally co-extruded on the rigid body, for example.

[0086] Optionally, the material of the soft covering layer includes, but is not limited to, soft rubber such as PVC and TPE.

[0087] In one specific embodiment, the materials of the soft wrapping layer and the buckle 41 are, for example, soft rubber such as PVC or TPE. The rigid body, the soft wrapping layer and the buckle 41 are co-extruded in two colors. The soft rubber wrapping layer is wrapped around the outside of the rigid body and is integrally connected with the buckle 41.

[0088] As display devices become larger, the size of the back cover 20 also increases accordingly. For back covers 20 of 100 inches and above, when one-piece injection molding is chosen, on the one hand, an injection molding machine of more than 2,000 tons is required, and injection molding resources are scarce; on the other hand, the number of mold gates is more than 40, making heating system wiring difficult, mold temperature uniformity low, injection molding process adjustment difficult, and yield rate low.

[0089] Please see Figure 3 , Figure 4 and Figure 7 Based on this, the rear shell 20 in this embodiment includes, for example, at least two separate shells 201. The at least two separate shells 201 are arranged sequentially along the width direction. That is, the rear shell 20 is divided into at least two separate shells 201 arranged along the width direction, and each separate shell 201 is processed and formed separately. Compared to using a single injection molding method for the entire rear shell 20, this reduces processing difficulty and increases yield.

[0090] Based on the aforementioned embodiments, at least two separate shells 201 are each provided with a mounting part 22 and are connected to the frame 40. In this way, the frame 40 can connect at least two separate shells 201 together, solving the problem of left and right swaying caused by gravity and providing better anti-torsion effect.
