Description

Technical Field

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

[0002] With the upgrading of consumer demand and the continuous development of technology, display devices such as televisions and monitors are becoming increasingly intelligent. In particular, in the television field, remote receiving devices that can perform remote voice recognition and interaction have been widely used.

[0003] Existing display devices typically include a housing, a display screen, and a light guide structure. The display screen is fixed to the housing, and the light guide structure includes a first housing and a circuit board disposed on the first housing. The circuit board can receive or transmit signals through the first housing, thereby controlling the operation of the display device.

[0004] In the prior art, in order to improve the appearance of the display device, the light guide structure is usually placed inside the housing or at the bottom. This arrangement limits the light receiving angle of the light guide structure and affects its light-sensing performance. Utility Model Content

[0005] This application discloses a display device that can increase the light receiving angle of the light guide structure and improve the light-sensing performance of the light guide structure.

[0006] To achieve the above objectives, embodiments of this application disclose a display device, including:

[0007] case;

[0008] A display panel, disposed within an accommodating space formed by the housing, the display panel having a front side; and...

[0009] A light guide structure, wherein the light guide structure is disposed at the bottom of the housing, the light guide structure comprising:

[0010] A first housing, the first housing being connected to the housing;

[0011] A circuit board, disposed within the first housing, is equipped with a light-sensitive remote control head for receiving external remote control signals; and...

[0012] A light guide, the light guide being configured to transmit external light that is incident on the light-sensing remote control head;

[0013] The first housing includes:

[0014] The main body portion has a first outer edge surface facing the front side;

[0015] A flange portion is connected to the main body portion and extends out of the first outer edge surface, and the light guide is disposed on the flange portion.

[0016] By configuring the first housing to include a main body and a flange, with the flange extending beyond the first outer edge of the main body, and a light guide component disposed on the flange, the extended flange lengthens the space at the light-sensing area, causing the light guide component to extend further forward. This increases the extension distance of the light guide component, reduces the obstruction of the light guide structure by the housing, and allows more light to enter the light guide component. Consequently, the light receiving angle of the light guide component increases, thereby increasing the overall light receiving angle of the display device and improving the light-sensing performance of the light guide structure.

[0017] As an alternative implementation, the flange has an arcuate surface facing the front side, the curvature of which is set along the width direction of the housing.

[0018] Since the flange of the first housing extends beyond the first outer edge of the main body, meaning the flange is closer to the front, it is not conducive to meeting the requirement of placing the first housing as far back as possible to achieve a concealed design and ensure a good appearance. Therefore, by making the surface of the protruding flange facing the front a horizontally curved arc, the abruptness of the appearance caused by the structural sharp angles can be reduced, resulting in a smoother overall appearance. At the same time, the arc surface can optimize the path of light incidence and refraction, expand the signal reception angle, reduce the signal blind zone, adapt to remote control operation at different angles, and improve the remote control performance of the light guide structure.

[0019] As an optional implementation, the maximum distance from the arcuate surface to the first outer edge surface along the thickness direction of the shell is L, where L satisfies: L≤4mm; and / or,

[0020] The flange portion has a first side and a second side along the width direction of the housing, and the light guide is disposed near the front side or the second side.

[0021] If the maximum distance from the curved surface along the thickness direction of the housing to the first outer edge, i.e., the extension length of the flange, is too large, the longer the light guide extends, the less the front side of the housing obstructs the first housing, the larger the light-gathering angle of the light guide, and the better the effect on improving light-sensing performance. However, if the first housing is positioned further forward relative to the front side of the housing, the first housing will be more prominent, which is not conducive to the concealed design of the first housing, affects the overall appearance of the display device, and excessive extension may lead to a decrease in the structural strength of the flange.

[0022] Therefore, by controlling the extension length within a reasonable range, the light-gathering angle of the light guide structure can be improved without making the light guide structure too prominent. This helps to meet the appearance requirements of the light guide structure and achieve the best balance between the light-gathering angle and the appearance effect.

[0023] By positioning the light guide near the first or second side of the flange, that is, by setting the light guide off-center, and given that the front end of the flange is curved, this offset positioning is more conducive to receiving infrared signals from the remote control from the side. Compared to a centered design, the light can be offset at a certain angle, allowing for the reception of incident light from a wider angle. This, in turn, helps to expand the remote control reception range and improve the remote control performance of the light guide structure.

[0024] As an optional implementation, the first housing has a receiving cavity, and the circuit board is disposed in the receiving cavity;

[0025] The first housing has an outer bottom surface that is away from the housing along the height direction of the housing, and the accommodating cavity is recessed toward the outer bottom surface to form a protrusion on the outer bottom surface, the protrusion having the flange portion.

[0026] By providing a receiving cavity on the first housing and placing the circuit board in the receiving cavity, the recessed receiving cavity can be used to achieve embedded protection of the circuit board, and can save vertical space and reduce the overall thickness of the first housing.

[0027] The accommodating cavity is recessed towards the outer bottom surface to form a protrusion on the outer bottom surface. That is, the protrusion is formed only on the outer bottom surface at the location corresponding to the accommodating cavity. This avoids the entire first housing having a uniform thickness, which would result in an excessively large overall volume of the first housing, hindering the concealed design of the light guide structure mounted behind the housing. Therefore, by using the recessed accommodating cavity to form the protrusion, the circuit board can be embedded within the accommodating cavity to provide protection, while the overall volume of the light guide structure is reduced, improving the aesthetic appearance of the light guide structure mounted on the housing.

[0028] In addition, the cavity is recessed towards the outer bottom surface to form a protrusion on the outer bottom surface. Since the circuit board is located in the cavity and the remote control receiver is located on the circuit board, the flange is formed on the protrusion to better correspond with the remote control receiver located on the circuit board, thus making the structural layout more reasonable.

[0029] As an optional implementation, the protrusion includes:

[0030] The first part extends along the width direction of the housing;

[0031] The second part is connected to one side of the first part close to the front side. The size of the second part in the width direction of the housing is smaller than that of the first part, and the second part has the flange portion.

[0032] By dividing the raised part into two parts, the second part is connected to one side of the first part close to the front side. The size of the second part in the width direction of the housing is smaller than that of the first part, so that the raised part is roughly in a "convex" shape. In this way, after the first housing is installed on the housing, while ensuring the arrangement and performance of the circuit board, the smaller-sized second part is closer to the user's setting, and can visually reduce the exposed volume of the first housing, thus being more conducive to improving the appearance.

[0033] In addition, by dividing the raised part into two parts with different sizes, the optimization of mechanical properties can be achieved. When installing and adapting the circuit board to the accommodation cavity, the first part can provide the main support. Forming the flange portion on the second part with a smaller size can make the protruding flange portion improve the light sense while reducing the impact on the appearance due to the protrusion. At the same time, in the molding process of the raised part with this structural form, it is convenient for the injection mold to demold, improving the manufacturing yield.

[0034] As an optional implementation manner, a first sound pickup hole and a second sound pickup hole are provided on the surface of the first part facing the front side. The first sound pickup hole and the second sound pickup hole are arranged on both sides of the second part along the width direction of the housing.

[0035] Due to the different physical properties of light waves and sound waves, under the same occlusion condition, the degree of influence on sound waves is smaller. Therefore, in this application, the raised part is divided into the first part and the second part to form a "convex" shape, and the flange portion protruding forward is provided on the second part. On the premise of improving the light sense performance and the appearance effect, the sound pickup holes are arranged on the first part which is more backward than the light sense position. Without affecting the sound transmission, the space on the first housing can be more reasonably utilized, making the layout of the sound pickup holes more reasonable. In addition, by arranging the first sound pickup hole and the second sound pickup hole on both sides of the second part, a certain distance can be maintained between the two sound pickup holes, reducing the phase interference phenomenon in the sound pickup process through the two sound pickup holes, thereby improving the sound pickup effect.

[0036] As an optional implementation manner, the flange portion has a mounting hole, and at least part of the light guide member is disposed in the mounting hole; and / or,

[0037] The light guide member is arranged corresponding to the light-sensing remote control head in the thickness direction of the housing.

[0038] By providing mounting holes on the flange, the light guide can be placed in the mounting holes, which means that the light guide can be set independently relative to the flange. This modularizes the light guide and makes it easier to disassemble and replace it. When the light guide needs to be replaced, only the light guide needs to be replaced, without replacing the entire first housing, which helps to reduce maintenance costs.

[0039] By aligning the light guide along the thickness of the housing with the light-sensitive remote control head, the light passing through the light guide can illuminate the light-sensitive remote control head via the shortest path, thereby reducing optical path loss.

[0040] As an optional implementation, the housing is provided with a first connection structure, which is configured to connect light guide structures with different functions.

[0041] By providing a first connection structure on the housing, the first connection structure is configured to be suitable for connecting light guide structures with different functions. That is, the first connection structure on the housing for connecting with the light guide structure is set as a universal structure. Even light guide structures with different functions can be adapted to the housing without intermediate adapters or housing replacements. This reduces design or usage costs by utilizing a standardized first connection structure.

[0042] As an alternative implementation, the housing includes:

[0043] Front housing, the front housing having a mounting groove;

[0044] A rear shell connected to the front shell, a first shell connected between the front shell and the rear shell, and at least a portion of the first shell being accommodated in the mounting groove.

[0045] By connecting the front and rear shells to the first shell respectively, the connection of the first shell can be made more stable. Furthermore, by providing a mounting groove on the front shell and accommodating at least a portion of the first shell in the mounting groove, the portion of the first shell exposed outside the front and rear shells in the height direction of the shell is reduced, allowing the first shell to present a hidden design, which is more conducive to improving the overall appearance of the display device.

[0046] As an optional implementation, the first housing has first engaging portions on both sides along the width direction of the housing, and the mounting groove has two second engaging portions, with one of the first engaging portions engaging with one of the second engaging portions to limit the position of the first housing in the thickness direction of the housing; and / or,

[0047] The first housing has a receiving cavity, the circuit board is disposed in the receiving cavity, the first housing has an inner bottom surface and an inner peripheral surface, the inner peripheral surface surrounds the inner bottom surface to form the receiving cavity;

[0048] A first limiting protrusion is provided on the inner circumferential surface, and a first limiting groove communicating with the accommodating cavity is provided on the first limiting groove. The first limiting groove and the first limiting protrusion are correspondingly arranged along the thickness direction of the housing. A second limiting protrusion is provided in the mounting groove. The first limiting groove is configured to allow the second limiting protrusion to extend into it, so that the first limiting protrusion overlaps with the second limiting protrusion to limit the position of the first housing in the height direction of the housing; and / or,

[0049] The front side of the first housing is provided with a forward-extending latch, and the front housing is provided with a slot and a guide groove that communicate with the mounting groove. The guide groove extends along the thickness direction of the housing and communicates with the slot. The guide groove is configured to guide the latch to extend into the slot. The latch and the slot cooperate to restrict the position of the first housing in the height direction of the housing.

[0050] The first and second engaging parts are connected to restrict the movement of the first housing in the thickness direction. The first engaging parts are provided on both sides of the first housing, so that the engaging positions of the first housing are symmetrically distributed, which is more conducive to the reliability of the connection of the first housing.

[0051] By using the first limiting protrusion and the second limiting protrusion to restrict the movement of the first housing in the height direction, the second limiting protrusion can be inserted into the first limiting groove for alignment during the installation of the first housing. This avoids blind connection and affects assembly efficiency. In other words, the second limiting groove enables visualization of the alignment of the first limiting protrusion and the second limiting protrusion, making it easier to achieve their mutual cooperation and thus improving assembly efficiency.

[0052] By engaging the first and second engaging parts, the movement of the first housing along its width and height can be restricted. Furthermore, the guide groove communicating with the slot guides the tongue as it extends into the slot, ensuring a consistent movement trajectory and improving installation accuracy. The guide groove also aligns the tongue before installation, preventing misalignment and repeated installations that would otherwise require precise connection to the slot, thus improving assembly efficiency.

[0053] By using the limiting connections at different positions, the first housing is limited from different directions. Such a multi-level limiting connection can strengthen the connection stability between the first housing and the front housing, especially avoiding scenarios where the light guide structure is prone to failure due to vibration during transportation or use.

[0054] Compared with the prior art, the beneficial effects of this application are:

[0055] The display device provided in this application comprises a first housing including a main body and a flange, with the flange extending beyond the first outer edge of the main body, and a light guide disposed on the flange. This extended flange lengthens the space at the light-sensing area, causing the light guide to extend further forward, increasing its extension distance, reducing the housing's obstruction of the light guide structure, and allowing more light to enter the light guide. This increases the light-receiving angle of the light guide, thereby increasing the overall light-receiving angle of the display device and ultimately improving the light-sensing performance of the light guide structure.

[0081] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0082] This application discloses a display device 100, which includes, but is not limited to, electronic display products such as televisions, computer monitors, and liquid crystal display panels 20, and can be widely used in places such as homes, offices, conference halls, exhibition halls, stations, hospitals, or shopping malls.

[0083] See Figure 1In some embodiments, the display device 100 includes a housing 10. With reference to the display device 100 in its usage state, the direction facing the user is the front side 10a, and the direction away from the user is the rear side; the front-rear direction is the thickness direction X of the housing 10. The left-right direction from one side of the housing 10 to the other is the width direction Y of the housing 10. The vertical direction from the top to the bottom of the housing 10 is the up-down direction, which is the height direction Z of the housing 10.

[0084] In some embodiments, the display device 100 includes a display panel 20 disposed within an accommodating space (not shown) formed by the housing 10. The display panel has a front side 10a and is used to display image information for viewing by a user. It is understood that the front side 10a refers to the side facing the user.

[0085] In some embodiments, the display device 100 includes a light guide structure 30. The light guide structure 30 is disposed at the bottom of the housing 10 and is used to receive external remote control signals so that the user can control the operation of the display device 100 via remote control. That is, the user can remotely interact with the display device 100 through the light guide structure 30, thereby realizing the control of the display device 100.

[0086] In some embodiments, the display device 100 may further include a back plate (not shown), which is located behind the display panel 20. The back plate is the main support structure of the display device 100. The back plate is connected to the housing 10 to support the display screen, and encloses a mounting space between the two for the installation of the display panel 20.

[0087] In some embodiments, the display device 100 further includes a backlight module (not shown), which is disposed on the rear side of the display panel 20, between the back panel and the display panel 20. The backlight module may include a lamp plate, a reflector, a diffuser, and an optical film assembly arranged sequentially from back to front. The display panel 20 is located in front of the optical film assembly. The light emitted by the lamp plate is reflected by the reflector and then passes through the diffuser and the optical film assembly in sequence before reaching the display panel 20. The liquid crystal molecules in the front panel are deflected by the electric field, reducing the transmittance of light emitted from the optical film assembly into the liquid crystal panel. This causes the light to be projected onto filters of different colors to form an image, thereby displaying image information on the display panel 20.

[0088] The optical film assembly may include multiple films. These films may include brightness enhancement films and multiple prism sheets, or multiple films may include multiple prism sheets.

[0089] In some embodiments, the housing 10 is further provided with a motherboard, a power board, a sound component, and electronic components. The motherboard is mainly used to perform calculations on the control system of the display device 100 and output relevant operation commands accordingly. The light guide structure 30 can be electrically connected to the motherboard.

[0090] The power supply board is integrated on the motherboard and is mainly used to provide the motherboard with drive voltage or stable operating voltage and to keep the output current of the circuits on the motherboard stable when they are working.

[0091] The sound component can be located on the back, left and right sides or front 10a of the motherboard, and is mainly used to produce corresponding sounds in conjunction with the interface displayed on the display panel 20.

[0092] Electronic components are connected to the back of the motherboard. The motherboard has a large number of electronic components, which mainly transmit the operation commands output by the motherboard to the corresponding operation terminals.

[0093] See Figures 2 to 4 In some embodiments, the housing 10 may include a front housing 11 and a rear housing 12, with the rear housing 12 connected to the front housing 11. The front housing 11 and the rear housing 12, when connected, together enclose a space for accommodating the aforementioned components (e.g., backlight module, display panel 20, motherboard, power board, etc.).

[0094] In some embodiments, the light guide structure 30 includes a first housing 31, which is connected to the housing 10. It is understood that the first housing 31 is the housing 10 of the light guide structure 30, primarily used to support other components of the light guide structure 30. The first housing 31 may be connected to the front housing 11 and the rear housing 12.

[0095] Optionally, the shape of the first housing 31 can be square, rectangular, or other irregular shapes. Taking a rectangle as an example, the first housing 31 can extend along the width direction Y of the housing 10. Then, the width direction Y of the housing 10 can be the length direction of the first housing 31, the thickness direction X of the housing 10 can be the width direction of the first housing 31, and the height direction Z of the housing 10 can also be the thickness direction of the first housing 31.

[0096] Combination Figure 3 In some embodiments, the light guide structure 30 includes a circuit board 32 disposed inside the first housing 31. The circuit board 32 is provided with a light-sensing remote control head 32a for receiving external remote control signals.

[0097] In some embodiments, the light guide structure 30 includes a light guide 33, which is configured to transmit external light that is incident on the light-sensing remote control head 32a.

[0098] In related technologies, to improve the appearance of the display device 100, the design requirement for the light guide structure 30 is usually to be as concealed as possible. For example, the light guide structure 30 is placed inside or at the bottom of the housing 10. When the light guide structure 30 is placed at the bottom of the housing 10, its position relative to the front side 10a of the housing 10 is also as far back as possible to minimize its impact on the appearance. However, since the front side 10a of the housing 10 is higher than the front side 10a of the light guide structure 30, this arrangement blocks some of the light from the upper side from entering the light guide structure 30, thus limiting the light receiving angle of the light guide structure 30 and affecting its light-sensing performance.

[0099] Based on the above, in some embodiments, the first housing 31 includes a main body 311 having a first outer edge surface 311a facing the front side 10a.

[0100] Combination Figures 3 to 5 In some embodiments, the first housing 31 includes a flange portion 312, which is connected to the main body portion 311 and extends out of the first outer edge surface 311a, and the light guide 33 is disposed on the flange portion 312.

[0101] By configuring the first housing 31 to include a main body 311 and a flange 312, with the flange 312 extending beyond the first outer edge 311a of the main body 311, and the light guide 33 disposed on the flange 312, the extended flange 312 lengthens the space at the light-sensing area, causing the light guide 33 to extend further forward, increasing the extension distance of the light guide 33, reducing the obstruction of the first housing 31 by the housing 10, and allowing more light to enter the light guide 33. This increases the light receiving angle of the light guide 33, thereby increasing the overall light receiving angle of the display device 100, and ultimately improving the light-sensing performance of the light guide structure 30.

[0102] Combination Figure 4 As can be seen, by adopting the solution of this application, the first angle β1 based on the arc surface 312b of the flange portion 312 is greater than the second angle α based on the first outer edge surface 311a. Under the premise that the distance between the light-sensing remote control head and the front side 10a of the housing 10 remains unchanged, the light incident angle can be increased by lengthening the first housing 31, thereby improving the light-sensing performance.

[0103] Optionally, the light guide 33 can be made of transparent materials such as transparent PC (Polycarbonate) or transparent ABS (Acrylonitrile Butadiene Styrene). The light guide 33 and the first housing 31 can both be made of transparent materials, or the first housing 31 can be made of a non-transparent material.

[0104] Furthermore, the light guide 33 can be integrally formed with the first housing 31. For example, when the two are made of different materials, the light guide 33 and the first housing 31 can be integrally injection molded by two-color injection molding. Alternatively, the light guide 33 can be separately formed from the first housing 31.

[0105] Continue reading Figure 3 In some embodiments, the flange portion 312 has a mounting hole 312a, and the light guide 33 is at least partially disposed in the mounting hole 312a. By providing a mounting hole 312a on the flange portion 312, the light guide 33 is disposed in the mounting hole 312a, that is, the light guide 33 can be disposed independently relative to the flange portion 312, making the light guide 33 modular and more conducive to the disassembly and replacement of the light guide 33. When it is necessary to replace the light guide 33, only the light guide 33 needs to be replaced, without replacing the entire first housing 31, thereby further reducing maintenance costs.

[0106] Combination Figure 4 In some embodiments, the light guide 33 is disposed along the thickness direction X of the housing 10 corresponding to the light-sensing remote control head. By disposing the light guide 33 along the thickness direction X of the housing 10 corresponding to the light-sensing remote control head, the light passing through the light guide 33 can illuminate the light-sensing remote control head 32a with the shortest path, thereby reducing optical path loss.

[0107] Combination Figure 5 and Figure 6 In some embodiments, the flange portion 312 has an arcuate surface 312b facing the front side 10a, and the curvature direction of the arcuate surface 312b is set along the width direction Y of the housing 10.

[0108] Since the flange portion 312 of the first housing 31 extends beyond the first outer edge surface 311a of the main body portion 311, that is, the flange portion 312 is closer to the front side 10a of the housing 10, it is not conducive to meeting the requirement of setting the first housing 31 as far back as possible to achieve a hidden design and ensure the appearance effect. Therefore, by setting the surface of the protruding flange portion 312 facing the front side 10a as a horizontally curved arc surface 312b, the abruptness of the appearance caused by the structural corners can be reduced, thereby making the overall appearance smoother. At the same time, the setting of the arc surface 312b can optimize the path of light incidence and refraction, expand the signal receiving angle, reduce the signal blind zone, adapt to remote control operation at different angles, and improve the remote control performance of the light guide structure 30.

[0109] It should be noted that the surface of the light guide 33 facing the front side 10a can be adapted to the shape of the arc surface 312b, that is, the surface of the light guide 33 facing the front side 10a can also be arc-shaped.

[0110] In this application, a light guide 33 is provided at the light-sensing position in the first housing 31. The light guide 33 refracts and reflects light to guide the light sensor head, thereby enabling the light sensor head to sense light. Since the flange portion 312 of the first housing 31 extends out of the first outer edge surface 311a of the main body portion 311, this structural design allows the light guide 33 to extend forward. The extension of the light guide 33 used for sensing can provide a light receiving angle. Compared with related technologies, the front end of the first housing 31 is a flat surface, which reduces the obstruction of the housing 10 and increases the light receiving angle, thereby improving the light sensing performance.

[0111] It is understandable that the longer the forward-extending portion of the first housing 31, the greater the extension distance of the light guide 33, and the greater the improvement in the light sensing angle, which is more beneficial to the light sensing performance. However, this contradicts the requirement of keeping the first housing 31 as concealed as possible to ensure aesthetic appeal, meaning it is not conducive to meeting aesthetic requirements. Therefore, in order to balance the performance and aesthetic requirements of the first housing 31, combined with... Figure 7 In some embodiments, the maximum distance from the arcuate surface 312b along the thickness direction X of the housing 10 to the first outer edge surface 311a is L, where L satisfies: L≤4mm. Optionally, L can satisfy L≤3.5mm, L≤3mm, or L≤2mm, for example, L can be 2mm, 3mm, or 4mm, etc.

[0112] If the maximum distance from the arcuate surface 312b along the thickness direction X of the housing 10 to the first outer edge surface 311a, i.e., the extension length of the flange portion 312, is too large, the longer the light guide 33 extends, the less the front side 10a of the housing 10 blocks the first housing 31, the larger the light-gathering angle of the light guide 33, and the better the effect on improving the light-sensing performance. However, the position of the first housing 31 relative to the front side 10a of the housing 10 is further forward, making the first housing 31 more prominent, which is not conducive to the concealed design of the first housing 31, affects the overall appearance of the display device 100, and excessive extension may lead to a decrease in the structural strength of the flange portion 312.

[0113] Therefore, by controlling the extension length within a reasonable range, the light-receiving angle of the first housing 31 can be improved without making the first housing 31 too protruding, which helps to meet the appearance requirements of the light guide structure 30 and achieve the best balance between the light-receiving angle and appearance of the light guide structure 30.

[0114] Combination Figure 7 and Figure 8 In some embodiments, the flange portion 312 has a first side 312c and a second side 312d along the width direction Y of the housing 10, and the light guide 33 is disposed near the first side 312c or the second side 312d.

[0115] By positioning the light guide 33 close to either the first side 312c or the second side 312d of the flange portion 312—that is, by positioning the light guide 33 off-center—it is more advantageous to receive infrared signals from the remote control from the side, given that the front end of the flange portion 312 is an arc-shaped surface 312b. Compared to a centered design, the light can be offset by a certain angle, allowing for the reception of incident light from a wider angle, thereby expanding the remote control reception range and improving the remote control performance of the light guide structure 30.

[0116] The front side 10a of the flange portion 312 is configured as an arc-shaped surface 312b, and the light guide 33 is positioned closer to the side, which is more conducive to receiving infrared signals from the remote control from the side. Figure 8 As shown in the diagram, the normal O1 is perpendicular to the tangent O2 on the arc surface. The normal is offset by a certain angle from the vertical line O3. Therefore, compared to a plane, it can receive light rays with a larger incident angle (the angle between the incident light ray O4 and the normal O1), thereby receiving a wider range of signals and improving the sensitivity of remote control.

[0117] See Figure 9 and Figure 10 In some embodiments, the first housing 31 has a receiving cavity 310, and the circuit board 32 is disposed in the receiving cavity 310. Specifically, the first housing 31 has an inner bottom surface 31a and an inner peripheral surface 31b, with the inner peripheral surface 31b surrounding the inner bottom surface 31a to form the receiving cavity 310.

[0118] By providing a receiving cavity 310 on the first housing 31 and placing the circuit board 32 in the receiving cavity 310, the recessed receiving cavity 310 can be used to achieve embedded protection of the circuit board 32, and can save vertical space and reduce the overall thickness of the first housing 31.

[0119] The mounting hole 312a can be connected to the accommodating cavity 310, and a part of the light guide 33 can be embedded in the mounting hole 312a, while the other part can extend into the accommodating cavity 310.

[0120] Continue reading Figure 9 and Figure 10 In some embodiments, the accommodating cavity 310 is provided with a limiting tongue 313 and a limiting buckle 314 spaced apart along the thickness direction X of the housing 10. The limiting tongue 313 and the limiting buckle 314 abut against the surface of the circuit board 32 to fix the circuit board 32.

[0121] Optionally, the bottom of the limiting tongue 313 is connected to the inner bottom surface 31a of the receiving cavity 310, and the periphery of the limiting tongue 313 is connected to the inner peripheral surface 31b of the receiving cavity 310 to ensure the stability of the limiting tongue 313, thereby ensuring the stability of the circuit board 32. The limiting buckle 314 is a suspended structure. Specifically, the bottom of the limiting buckle 314 is connected to the inner bottom surface 31a of the receiving cavity 310, and the periphery of the limiting buckle 314 does not contact the inner peripheral surface 31b, so that the limiting buckle 314 is elastic, thereby allowing the limiting buckle 314 to undergo elastic deformation, so as to facilitate the installation and removal of the circuit board 32.

[0122] Understandably, the limiting tongue 313 is also a snap-fit ​​type. The main difference is that the bottom and periphery of the limiting tongue 313 are connected to the wall of the receiving cavity 310, making the structure more stable and less prone to deformation.

[0123] Combination Figure 9 In some embodiments, a limiting post 315 is also provided in the accommodating cavity 310, and the limiting post 315 extends along the height direction Z (thickness direction of the first housing 31) of the housing 10 to support the circuit board 32.

[0124] In one example, the limiting post 315 protrudes directly onto the inner bottom surface 31a of the accommodating cavity 310, and the periphery of the limiting post 315 does not contact the inner peripheral surface 31b of the accommodating cavity 310. The top end of the limiting post 315 supports the circuit board 32.

[0125] In another example, the limiting post 315 protrudes from the inner bottom surface 31a of the accommodating cavity 310, and a step 315a is formed on the limiting post 315. The lower end and periphery of the circuit board 32 abut against the step 315a. By abutting the lower end and periphery of the circuit board 32 through the step 315a, the circuit board 32 can not only be supported, but also its periphery can be limited.

[0126] Optionally, there can be multiple limiting posts 315. Multiple limiting posts 315 are arranged at intervals along the circumference of the accommodating cavity 310 on the inner circumferential surface 31b. By using multiple limiting posts 315 to limit the circumference of the circuit board 32, the movement of the circuit board 32 in the horizontal direction can be restricted, which is more conducive to the stability of the circuit board 32.

[0127] The upper end of the limiting post 315 may also be provided with an inclined guide slope 315b, which plays a guiding role when the circuit board 32 is placed on the limiting post 315, so as to facilitate the placement of the circuit board 32.

[0128] When installing the circuit board 32, one end of the circuit board 32 needs to be inserted into the receiving cavity 310. The end of the circuit board 32 is inserted under the limiting tongue 313 in an inclined manner. Then, the circuit board 32 is pressed down so that the circuit board 32 is supported on the limiting post 315 and the limiting buckle 314 is elastically deformed and finally locked onto the other end of the circuit board 32.

[0129] See Figure 11 In some embodiments, the first housing 31 has an outer bottom surface 31c that is opposite to the housing 10 along the height direction Z, and the accommodating cavity 310 is recessed toward the outer bottom surface 31c to form a protrusion 316 on the outer bottom surface 31c. The protrusion 316 has a flange 312, that is, the flange 312 is located on the protrusion 316.

[0130] The accommodating cavity 310 is recessed towards the outer bottom surface 31c to form a protrusion 316 on the outer bottom surface 31c. That is, the protrusion 316 is formed only on the outer bottom surface 31c at the position corresponding to the location where the accommodating cavity 310 is formed. In this way, it is possible to avoid the entire first housing 31 having a uniform thickness. If the thickness were uniform, the overall volume of the first housing 31 would be too large, which would be detrimental to the concealed design of the light guide structure 30 installed behind the housing 10. Therefore, by forming the protrusion 316 by recessing the accommodating cavity 310, the circuit board 32 can be embedded in the accommodating cavity 310 to achieve the protection of the circuit board 32, while also reducing the overall volume of the light guide structure 30, which is more conducive to the appearance of the light guide structure 30 installed on the housing 10.

[0131] Furthermore, the accommodating cavity 310 is recessed towards the outer bottom surface 31c to form a protrusion 316 on the outer bottom surface 31c. Since the circuit board 32 is located in the accommodating cavity 310 and the remote control receiver is located on the circuit board 32, the flange 312 is formed on the protrusion 316 to better correspond with the remote control receiver located on the circuit board 32, thus making the structural layout more reasonable.

[0132] It should be noted that the outer bottom surface 31c refers to the outer bottom surface 31c that is opposite to the inner bottom surface 31a of the accommodating cavity 310 along the height direction Z of the housing 10. Taking the display device 100 placed on the table as an example, the outer bottom surface 31c is the surface of the first housing 31 facing the table.

[0133] Continue to combine Figure 11 In some embodiments, the protrusion 316 includes a first portion 316a that extends along the width direction Y of the housing 10. That is, the first portion 316a can extend along the length direction of the first housing 31, so that the accommodating cavity 310 can have a larger space in this direction to accommodate a larger circuit board 32.

[0134] In some embodiments, the protrusion 316 includes a second part 316b which is connected to a side of the first part 316a close to the front side 10a, and the dimension of the second part 316b in the width direction Y of the housing 10 is smaller than that of the first part 316a. Wherein, the second part 316b has a flange portion 312, that is, the flange portion 312 is on the second part 316b. Specifically, the flange portion 312 is located on a side of the second part 316b close to the front side 10a.

[0135] By dividing the protrusion 316 into two parts, with the second part 316b connected to a side of the first part 316a close to the front side 10a and the dimension of the second part 316b in the width direction Y of the housing 10 being smaller than that of the first part 316a, the protrusion 316 generally presents a "convex" shape. In this way, after the first housing 31 is mounted on the housing 10, while ensuring the arrangement and performance of the circuit board 32, the smaller-sized second part 316b is closer to the user setting, which can visually reduce the exposed volume of the first housing 31, thus being more conducive to the appearance improvement.

[0136] In addition, by dividing the protrusion 316 into two parts with different dimensions, the optimization of mechanical properties can be achieved. When installing and fitting the circuit board 32 in the accommodating cavity 310, the first part 316a can provide the main support. Forming the flange portion 312 on the smaller-sized second part 316b can enable the protruding flange portion 312 to enhance the light sense while reducing the impact on the appearance due to the protrusion. At the same time, in the molding process of the protrusion 316 with this structural form, it is convenient for the injection mold to demold, improving the manufacturing yield.

[0137] In some embodiments, a first connection structure is provided on the housing 10, and the first connection structure is configured to be suitable for connecting light guide structures 30 with different functions. That is, the display device 100 provided in this application can be compatible with light guide structures 30 with different functions.

[0138] It should be noted that the first housings 31 of the above light guide structures 30 with different functions can have the same shape and size, and the second connection structures for cooperating with the first connection structure are also the same, while the circuit boards 32 provided on the first housings 31 can be of different specifications and models to have different functions.

[0139] By providing a first connection structure on the housing 10, the first connection structure is configured to be suitable for connecting light guide structures 30 with different functions. That is, the first connection structure on the housing 10 for connecting with the light guide structure 30 is set as a universal structure. Even if the light guide structure 30 has different functions, it can be adapted to the housing 10 without intermediate adapters or replacement of the housing 10. Thus, the standardized first connection structure can be used to reduce design or usage costs.

[0140] Optionally, the first connection structure can be a buckle, a slot 113, a limiting step 315a, etc., for connecting the light guide structure 30, as long as the first connection structure can be adapted to the light guide structure 30 with different functions.

[0141] In one example, see the above-mentioned Figures 2 to 11 The light guide structure 30 shown can be a circuit board 32 that enables WiFi functionality. The circuit board 32 can be square, and the square circuit board 32 can be set only in part of the receiving cavity 310.

[0142] See another example. Figures 12 to 14 The light guide structure 30 shown can be connected to the front housing 11 and the rear housing 12 in the same way. The circuit board 32 can be adapted to the accommodating cavity 310. This circuit board 32 can be any type of circuit board designed to perform sound pickup. In this example, the protrusion 316 of the first housing 31 can also include a first portion 316a and a second portion 316b. Furthermore, the circuit board 32 can be U-shaped to fit into the accommodating cavity 310.

[0143] Accordingly, the accommodating cavity 310 is provided with limiting tongues 313, limiting buckles 314, limiting posts 315 and other structures for connecting the circuit board 32, which are spaced apart along the thickness direction X of the housing 10. For details, please refer to the above description of this part, and will not be repeated here.

[0144] Combination Figure 13 and Figure 14 In some embodiments, a first pickup hole 316a1 and a second pickup hole 316a2 are provided on the front-facing surface of the first part 316a, and the first pickup hole 316a1 and the second pickup hole 316a2 are respectively disposed on both sides of the second part 316b along the width direction Y of the housing 10.

[0145] Due to the different physical properties of light waves and sound waves, when similarly blocked, the degree of influence on sound waves is smaller. Therefore, in this application, the protruding part is formed by a first part 316a and a second part 316b into a "convex" shape, and the flange part 312 protruding forward is arranged on the second part 316b. On the premise of improving the light-sensing performance and the appearance effect, the sound pickup holes are arranged on the first part 316a which is more backward than the light-sensing position. Without affecting the sound transmission, the space on the first housing 31 can be more reasonably utilized, making the layout of the sound pickup holes more reasonable.

[0146] In addition, by arranging the first sound pickup hole 316a1 and the second sound pickup hole 316a2 on both sides of the second part 316b respectively, a certain distance can be maintained between the two sound pickup holes, reducing the phase interference phenomenon in the process of picking up sound through the two sound pickup holes, thereby improving the sound pickup effect.

[0147] It can be understood that sound pickup elements are respectively arranged on the circuit board corresponding to the first sound pickup hole 316a1 and the second sound pickup hole 316a2 to ensure the best sound pickup effect.

[0148] Optionally, the number of the first sound pickup holes 316a1 can be one, two or more, and correspondingly, the number of the second sound pickup holes 316a2 can also be one, two or more.

[0149] In order to realize the connection between the light guide structure 30 and the housing 10, the connection structure will be introduced below by taking the light guide structure of a circuit board 32 with WiFi function as an example.

[0150] See Figure 15 , in some embodiments, the front housing 11 has an installation groove 110, the first housing 31 is connected between the front housing 11 and the rear housing 12, and at least part of the first housing 31 is accommodated in the installation groove 110.

[0151] By using the front housing 11 and the rear housing 12 to be respectively connected to the first housing 31, the connection of the first housing 31 can be made more stable. And, by setting the installation groove 110 on the front housing 11 and accommodating at least part of the first housing 31 in the installation groove 110, in the height direction Z of the housing 10, the part of the first housing 31 exposed outside the front housing 11 and the rear housing 12 is reduced, and the first housing 31 can present a hidden design, which is more conducive to improving the appearance effect of the entire display device 100.

[0152] Please refer to Figures 15 to 17In some embodiments, the first housing 31 is provided with first engaging portions 317 on both sides along the width direction Y of the housing 10, and two second engaging portions 111 are provided in the mounting groove 110. One first engaging portion 317 engages with one second engaging portion 111 to limit the position of the first housing 31 in the thickness direction X of the housing 10.

[0153] The first engaging portion 317 and the second engaging portion 111 are engaged to restrict the movement of the first housing 31 in the thickness direction X of the housing 10. The first engaging portion 317 is provided on both sides of the first housing 31, so that the engaging positions of the first housing 31 are symmetrically distributed, which is more conducive to the reliability of the connection of the first housing 31.

[0154] Optionally, the first engaging portion 317 may include a cantilever arm 317a and a hook 317b connected to the cantilever arm 317a. One end of the cantilever arm 317a is connected to the first housing 31, and the other end of the cantilever arm 317a extends along the thickness direction X (width direction of the first housing 31) of the housing 10. The hook 317b is disposed at the other end of the cantilever arm 317a, and there is a gap between the cantilever arm 317a and the first housing 31 in the length direction of the first housing 31. The protruding direction of the hook 317b is consistent with the opening direction of the receiving cavity 310.

[0155] The cantilever arm 317a allows the first engaging portion 317 to be elastic, making it easier for the hook 317b to engage with the second engaging portion 111 on the housing 10. Correspondingly, the second engaging portion 111 on the front housing 11 is a bayonet.

[0156] Optionally, the first engaging portion 317 may be formed by extending outward from the side of the housing 10 in the width direction Y (length direction of the first housing 31), or the first engaging portion 317 may extend into the interior of the first housing 31, and the side of the first engaging portion 317 may form part of the side of the first housing 31, that is, the side of the first engaging portion 317 may be aligned with the side of the first housing 31.

[0157] Preferably, the first engaging portion 317 extends into the interior of the first housing 31, and the side of the first engaging portion 317 is aligned with the side of the first housing 31. With this arrangement, the size of the first housing 31 is not excessively increased while still achieving the engaging connection between the first engaging portion 317 and the second engaging portion 111, which is more conducive to the miniaturization of the first housing 31.

[0158] Combination Figures 15 to 17In some embodiments, a first limiting protrusion 318 is provided on the inner peripheral surface 31b, and a first limiting groove 318a is provided on the first housing 31 to communicate with the accommodating cavity 310. The first limiting groove 318a and the first limiting protrusion 318 are correspondingly arranged along the thickness direction X of the housing 10. A second limiting protrusion is provided in the mounting groove 110. The first limiting groove 318a is configured to allow the second limiting protrusion to extend into it so that the first limiting protrusion 318 overlaps with the second limiting protrusion to limit the position of the first housing 31 in the height direction Z of the housing 10.

[0159] By using the first limiting protrusion 318 and the second limiting protrusion to restrict the movement of the first housing 31 in the height direction Z of the housing 10, the second limiting protrusion can be inserted into the first limiting groove 318a for alignment during the installation of the first housing 31. This avoids blind connection and affects assembly efficiency. In other words, the second limiting groove enables visualization of the alignment of the first limiting protrusion 318 and the second limiting protrusion, making it easier to achieve their mutual cooperation. This facilitates the installation and alignment of the first limiting protrusion 318 and the second limiting protrusion, avoids assembly errors caused by blind connection, and thus helps improve assembly efficiency.

[0160] Optionally, the first limiting protrusion 318 may include two, and the two first limiting protrusions 318 are arranged along the width direction Y of the housing 10. The first limiting protrusion 318 is arranged near the opening of the receiving cavity 310 in the height direction Z of the housing 10 (the thickness direction of the first housing 31), and the first limiting groove 318a is arranged corresponding to the first limiting protrusion 318 in the thickness direction X of the housing 10 (the width direction of the first housing 31), and the first limiting groove 318a communicates with the receiving cavity 310.

[0161] Based on the above description, when the first housing 31 is installed on the housing 10, the first housing 31 is aligned with the installation position on the front housing 11, the second limiting protrusion of the front housing 11 is inserted into the first limiting groove 318a on the first housing 31, and then the first housing 31 is pushed forward so that the first limiting protrusion 318a on the first housing 31 and the second limiting protrusion on the front housing 11 overlap in the height direction Z of the housing 10. The latch 319 on the first housing 31 moves along the guide groove 114 until the latch 319 extends into the latch groove 113 on the front housing 11, and the first limiting protrusion 318a of the first housing 31 engages with the second limiting protrusion on the front housing 11, thereby completing the installation of the first housing 31 and the front housing 11.

[0162] Combination Figure 15 and Figure 16In some embodiments, the front side 10a of the first housing 31 is provided with a forward-extending latch 319, and the front housing 11 is provided with a slot 113 and a guide groove 114 communicating with the mounting groove 110. The guide groove 114 extends along the thickness direction X of the housing 10 and communicates with the slot 113. The guide groove 114 is configured to guide the latch 319 into the slot 113. The latch 319 and the slot 113 are engaged to limit the position of the first housing 31 in the height direction Z of the housing 10.

[0163] The first engaging part 317 and the second engaging part 111 are connected to restrict the movement of the first housing 31 along the width direction Y and the height direction of the housing 10. The guide groove 114, which communicates with the slot 113, guides the tongue 319 into the slot 113, ensuring that the movement trajectory of the tongue 319 is consistent and improving the accuracy of installation. The guide groove 114 can also align the tongue 319 before installation, avoiding the situation where the tongue 319 is misaligned and cannot be accurately connected to the slot 113, thus requiring repeated installation and improving assembly efficiency.

[0164] In addition, the latch 319 on the first housing 31 engages with the corresponding slot 113 on the housing 10 to facilitate the installation and removal of the first housing 31 on the housing 10. The slot 113 and the latch 319 have simple structures and are easy to form in different materials, thereby enabling the installation of the first housing 31 on the housing 10 to be compatible with different circuit boards 32.

[0165] Optionally, there can be multiple latches 319, which are spaced apart along the length of the first housing 31. Correspondingly, there are also multiple slots 113 on the housing 10, each corresponding to one of the latches 319. The guide groove 114 extends along the thickness direction X (front-back direction) of the housing 10. Thus, after the connection part of the guide member is aligned, the first housing 31 can be pushed forward along the thickness direction X of the housing 10, and the latches 319 extend into the slots 113 under the guidance of the guide groove 114.

[0166] It should be noted that the first engaging portion 317, the first limiting protrusion 318, the first limiting groove 318a, and the latch 319 on the first housing 31 can be arranged in any combination. That is, they can be arranged individually, in pairs, or all three can be arranged simultaneously. Preferably, the first housing 31 is provided with the first engaging portion 317, the first limiting protrusion 318, the first limiting groove 318a, and the latch 319, which are respectively connected to the corresponding components on the front housing 11. Through the limiting connection at different positions, the first housing 31 is limited from different directions. Such a multi-level limiting connection can strengthen the stability of the connection between the first housing 31 and the front housing 11, especially avoiding the scenario where the light guide structure 30 is prone to failure due to vibration during transportation or use.

[0167] It is worth noting that, in order to enable the display device 100 to be compatible with light guide structures 30 with different functions, the first connecting structure on the housing 10 is adapted to connect light guide structures 30 with different functions. In this case, the first connecting structure may include the second engaging portion 111, the second limiting protrusion, and the latch 319 described above. Correspondingly, the second connecting structure may include the first engaging portion 317, the first limiting protrusion 318, the first limiting groove 318a, and the latch 319 disposed on the first housing 31. Specifically, the first housing 31 of different light guide structures 30 is provided with the first engaging portion 317, the first limiting protrusion 318, the first limiting groove 318a, and the latch 319 respectively connected to the second engaging portion 111, the second limiting protrusion, and the latch 319. Thus, even light guide structures 30 with different functions can be directly adapted and installed on the housing 10 by using a first housing 31 with the same first connecting structure and external dimensions, and by combining it with circuit boards 32 with different functions, without the need for an adapter structure or replacement of the housing 10.

[0168] It is understood that the second engaging portion 111, the second limiting protrusion, the slot 113, and the guide groove 114 described above are all disposed in the mounting groove 110, and a portion of the first housing 31 is accommodated in the mounting groove 110. The guide groove 114 is disposed on the bottom wall of the mounting groove 110, and the slot 113 is disposed on the side wall of the mounting groove 110, with the slot 113 located at the end of the guide groove 114 extending in the direction of extension.

[0169] Optionally, the mounting groove 110 is semi-enclosed, meaning that the mounting groove 110 not only has an opening in the vertical direction, but also an opening on one side in the front-rear direction, i.e., one side of the mounting groove 110 extends through the edge of the front housing 11. In this way, it is convenient for the first housing 31 to be connected to the various connecting structures on the front housing 11 in a pushing manner.

[0170] The following is a brief description of the installation process of the first housing 31 on the housing 10 in the display device 100 of this application:

[0171] The circuit board 32 is installed in the receiving cavity 310 of the first housing 31, and then the first housing 31 is snapped onto the housing 10 so that it can receive external remote control signals from outside the housing 10. Specifically, the front end of the first housing 31 is provided with a latch 319, the two sides are provided with first engaging portions 317, and the inner peripheral surface 31b of the receiving cavity 310 is provided with a first limiting protrusion 318. The bottom surface of the front housing 11 is provided with a mounting groove 110. The side wall of the mounting groove 110 near the front end is provided with a slot 113, and the bottom wall is provided with a guide groove 114, a second engaging portion 111, and a second limiting protrusion. After the first limiting protrusion 318 and the second limiting protrusion are aligned, the guide groove 114 is pushed to the side wall. The guide component is gradually accommodated in the mounting groove 110. The first limiting protrusion 318 and the second limiting protrusion overlap each other. The latch 319 can extend into the slot 113 along the guide groove 114. The first engaging part 317 engages with the second engaging part 111, so that the first housing 31 engages with the front housing 11. Then, the rear housing 12 is engaged with the part exposed outside the accommodating cavity 310, thereby realizing the installation of the first housing 31 with the front housing 11 and the rear housing 12. When it is necessary to disassemble the first housing 31, the rear housing 12 is disengaged from the front housing 11 and the first housing 31. The first engaging part 317 and the second engaging part 111 are separated, and the first housing 31 is moved to the rear, so that the first limiting protrusion 318 and the second limiting protrusion, the latch 319 and the slot 113 are all separated, thereby separating the first housing 31 and the front housing 11.
