The front case 11 and the rear case 12 are connected and then together enclose a receiving space in which the above components (e.g., backlight module, display panel 20, motherboard, power panel, etc.) can be disposed.

In some embodiments, the light guiding structure 30 includes a first housing 31, and the first housing 31 is connected to the housing 10. It is understood that the first housing 31 is the housing 10 of the light guiding structure 30, and is mainly used for carrying other components of the light guiding structure 30. Wherein the first housing 31 may be connected to the front case 11 and the rear case 12.

Alternatively, the shape of the first housing 31 may be square, rectangular, or other irregular shape.

Then, the width direction Y of the housing 10 may be the longitudinal direction of the first housing 31, the thickness direction X of the housing 10 may be the width direction of the first housing 31, and the height direction Z of the housing 10 may be the thickness direction of the first housing 31.

Referring to fig. 3, in some embodiments, the light guiding structure 30 includes a circuit board 32, the circuit board 32 is disposed in the first housing 31, and a light sensing remote control head 32a is disposed on the circuit board 32 for receiving an external remote control signal.

In some embodiments, the light guide structure 30 includes a light guide 33, and the light guide 33 is configured to transmit external light irradiated onto the light-sensitive remote control head 32 a.

In the related art, in order to achieve the external appearance of the display device 100, the design of the light guiding structure 30 is generally designed to be as hidden as possible, for example, the light guiding structure 30 is disposed in the interior or at the bottom of the housing 10. When the light guiding structure 30 is disposed at the bottom of the housing 10, the light receiving angle of the light guiding structure 30 is limited, and the light sensing performance of the light guiding structure 30 is affected because the front side 10a of the housing 10 is higher than the front side 10a of the light guiding structure 30, and the light guiding structure 30 blocks the upper part of the light from entering the light guiding structure 30.

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

Referring to fig. 3 to 5, in some embodiments, the first housing 31 includes a flange portion 312, the flange portion 312 is connected to the main body portion 311 and protrudes from the first outer edge surface 311a, and the light guide 33 is disposed on the flange portion 312.

By providing the first housing 31 to include the main body portion 311 and the flange portion 312, the flange portion 312 is provided to protrude from the first outer edge surface 311a of the main body portion 311, and the light guide 33 is provided on the flange portion 312. In this way, the space at the light sensing position is lengthened by the protruding flange portion 312, so that the light guide member 33 is also protruded forwards, the extending distance of the light guide member 33 is increased, the shielding of the casing 10 to the first casing 31 is reduced, more light is made to be incident on the light guide member 33, the light receiving angle of the light guide member 33 is increased, the overall light receiving angle of the display device 100 is increased, and further the light sensing performance of the light guide structure 30 is improved.

As can be seen from fig. 4, according to the embodiment of the present application, the first angle β1 based on the arc surface 312b of the flange 312 is larger than the second angle α based on the first outer edge surface 311a, so that the light incident angle can be increased by lengthening the first housing 31 on the premise that the distance between the light-sensitive remote control head and the front side 10a of the housing 10 is unchanged, and the light-sensitive performance can be further improved.

Alternatively, the light guide 33 may be made of a transparent material such as a transparent PC (Polycarbonate) material or a transparent ABS (Acrylonitrile Butadiene Styrene, acrylonitrile-styrene-butadiene copolymer) material. The light guide 33 and the first housing 31 may be made of transparent materials, or the first housing 31 may be made of non-transparent materials.

Further, the light guide 33 may be integrally provided with the first housing 31, for example, when the two are of different materials, the light guide 33 may be integrally injection-molded with the first housing 31 by double-shot injection molding. Or the light guide 33 may be provided separately from the first housing 31.

With continued reference to fig. 3, in some embodiments, the flange portion 312 has a mounting hole 312a thereon, and the light guide 33 is at least partially disposed in the mounting hole 312 a. By providing the mounting hole 312a on the flange portion 312, the light guide member 33 is provided in the mounting hole 312a, that is, the light guide member 33 can be independently provided with respect to the flange portion 312, so that the light guide member 33 is modularized, the disassembly and replacement of the light guide member 33 are facilitated, and when the light guide member 33 needs to be replaced, only the light guide member 33 needs to be replaced, and the whole first housing 31 does not need to be replaced, thereby being more beneficial to reducing the maintenance cost.

Referring to fig. 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 providing the light guide 33 along the thickness direction X of the housing 10 in correspondence with the light-sensitive remote control head, the light passing through the light guide 33 can be made to illuminate the light-sensitive remote control head 32a in the shortest path, and the optical path loss can be reduced.

Referring to fig. 5 and 6, in some embodiments, the flange portion 312 has an arcuate surface 312b facing the front side 10a, and a bending direction of the arcuate surface 312b is set along the width direction Y of the housing 10.

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, that is, the flange portion 312 is closer to the front side 10a of the housing 10, it is not advantageous to meet the requirement that the first housing 31 is disposed as far back as possible to realize a hidden design to ensure the appearance effect, and therefore, by setting the surface of the extending flange portion 312 facing the front side 10a as an arc surface 312b curved in the horizontal direction, the abrupt appearance caused by the structural corner angle can be reduced, and the overall appearance is smoother. Meanwhile, the arrangement of the arc-shaped surface 312b can optimize the incident and refractive paths of light, enlarge the signal receiving angle, reduce the signal blind area, adapt to remote control operations of different angles and improve the remote control performance of the light guide structure 30.

It should be noted that the surface of the light guide 33 facing the front side 10a may be adapted to the shape of the curved surface 312b, that is, the surface of the light guide 33 facing the front side 10a may be provided in an arc shape.

In the present application, the first housing 31 is provided with the light guide member 33 at the light sensing position, the light guide member 33 refracts and reflects the light to the upper surface of the light sensing head, so as to realize the light sensing of the light sensing head, and the flange portion 312 of the first housing 31 extends out of the first outer edge surface 311a of the main body portion 311, so that the light guide member 33 can extend forward, and the light guide member 33 for light sensing can extend to provide a light receiving angle, compared with the surface of which the front end of the first housing 31 is flush in the related art, the shielding of the housing 10 is reduced, and the light receiving angle becomes larger, thereby being beneficial to improving the light sensing performance.

It will be appreciated that the longer the portion of the first housing 31 extending forward, the greater the distance the light guide 33 extends, the greater the light-sensing angle is, which is more beneficial to the light-sensing performance, but is contrary to the requirement of the first housing 31 for ensuring the appearance effect, i.e. not beneficial to the satisfaction of the appearance requirement. Based on this, in order to satisfy both the performance and the appearance requirements of the first housing 31, in connection with fig. 7, in some embodiments, the maximum distance from the arcuate surface 312b to the first outer edge surface 311a in the thickness direction X of the housing 10 is L, and L satisfies that L is 4mm. Alternatively, L may satisfy L≤3.5 mm, L≤3 mm, or L≤2 mm, for example, L may be 2mm, 3mm, 4mm, or the like.

If the maximum distance from the arcuate surface 312b to the first outer edge surface 311a in the thickness direction X of the housing 10, that is, if the protruding length of the flange portion 312 is too large, the longer the light guide 33 is, the less the front side 10a of the housing 10 blocks the first housing 31, and the larger the light receiving angle of the light guide 33, the better the improvement effect on the light sensation performance. However, the first housing 31 is positioned more forward than the front side 10a of the housing 10, so that the first housing 31 is disposed more prominently, which is disadvantageous for the hidden design of the first housing 31, affects the overall appearance effect of the display device 100, and may cause a problem that the structural strength of the flange portion 312 is reduced due to excessive extension.

Therefore, by controlling the extension length within a reasonable range, the light receiving angle of the first housing 31 can be improved, and meanwhile, the first housing 31 is not too protruding, so that the appearance requirement of the light guide structure 30 is met, and the best balance point for realizing the light receiving angle and the appearance effect of the light guide structure 30 is achieved.

Referring to fig. 7 and 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 312 d.

By disposing the light guide 33 adjacent to the first side 312c or the second side 312d of the flange portion 312, i.e., disposing the light guide 33 non-centrally, the offset arrangement is more advantageous for laterally receiving the infrared signal of the remote control on the basis that the front end of the flange portion 312 is the arcuate surface 312 b. Compared with the centering design, the light can deviate a certain angle and can receive incident light with a larger angle, thereby being beneficial to expanding the remote control receiving range and improving the remote control performance of the light guide structure 30.

The front side 10a of the flange portion 312 is configured as an arc surface 312b, and the light guide 33 is disposed closer to the side surface, which is more favorable for receiving the infrared signal of the remote controller, as shown in fig. 8, the simulated light ray trend is schematically shown, the normal O1 is perpendicular to the tangent O2 of the arc surface, and the normal is offset by a certain angle from the vertical O3, so that the light ray with a larger incident angle (the included angle between the incident light ray O4 and the normal O1) can be received compared with the plane, thereby being capable of receiving a larger range of signals and improving the sensitivity of remote control.

Referring to fig. 9 and 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, and the inner peripheral surface 31b surrounds the inner bottom surface 31a to form the accommodation chamber 310.

By providing the accommodating cavity 310 on the first housing 31 and disposing the circuit board 32 in the accommodating cavity 310, embedded protection of the circuit board 32 can be achieved by using the accommodating cavity 310, and vertical space can be saved, and the overall thickness of the first housing 31 can be reduced.

Wherein, the mounting hole 312a may be connected to the accommodating cavity 310, a portion of the light guide 33 may be embedded in the mounting hole 312a, and another portion may extend into the accommodating cavity 310.

With continued reference to fig. 9 and 10, in some embodiments, a limiting insert 313 and a limiting buckle 314 are disposed in the accommodating cavity 310 at intervals along the thickness direction X of the housing 10, and the limiting insert 313 and the limiting buckle 314 abut against the surface of the circuit board 32 for fixing the circuit board 32.

Optionally, the bottom of the limiting plug 313 is connected to the inner bottom 31a of the accommodating cavity 310, and the peripheral side of the limiting plug 313 is connected to the inner peripheral surface 31b of the accommodating cavity 310, so as to ensure the stability of the limiting plug 313, thereby ensuring the stability of limiting the circuit board 32. The limiting buckle 314 is of a suspended structure, specifically, the bottom of the limiting buckle 314 is connected with the inner bottom surface 31a of the accommodating cavity 310, and the peripheral side of the limiting buckle 314 is not contacted with the inner peripheral surface 31b, so that the limiting buckle 314 has elasticity, and the limiting buckle 314 can be elastically deformed, so that the circuit board 32 can be conveniently mounted and dismounted.

It can be appreciated that the limiting plug 313 is also in the form of a buckle, and the main difference is that the bottom and the peripheral side of the limiting plug 313 are connected with the wall surface of the accommodating cavity 310, so that the structure is more stable and is not easy to deform.

Referring to fig. 9, in some embodiments, a limiting post 315 is further disposed in the accommodating cavity 310, and the limiting post 315 extends along the height direction Z of the housing 10 (the thickness direction of the first housing 31) to support the circuit board 32.

In an example, the limiting post 315 is directly protruding on the inner bottom surface 31a of the accommodating cavity 310, the peripheral side of the limiting post 315 does not contact the inner peripheral surface 31b of the accommodating cavity 310, and the top end of the limiting post 315 is used for supporting the circuit board 32.

In another example, the limit post 315 protrudes from the inner bottom surface 31a of the accommodating cavity 310, a step 315a is formed on the limit post 315, and the lower end and the peripheral side of the circuit board 32 are abutted against the step 315a. By the abutment of the step 315a against the lower end and the peripheral side of the circuit board 32, not only the circuit board 32 can be carried, but also the peripheral side of the circuit board 32 can be restrained.

Optionally, the number of the limiting columns 315 may be multiple, and the plurality of limiting columns 315 are disposed on the inner peripheral surface 31b along the circumferential direction of the accommodating cavity 310 at intervals, and the plurality of limiting columns 315 are utilized to limit the circumferential side of the circuit board 32, so that the movement of the circuit board 32 in the horizontal direction can be limited, thereby being more beneficial to the stability of fixing the circuit board 32.

Wherein, the upper end of the spacing post 315 may further be provided with an inclined guiding slope 315b, which plays a guiding role when the circuit board 32 is placed on the spacing post 315, so as to facilitate placement of the circuit board 32.

When the circuit board 32 is mounted, one end of the circuit board 32 needs to be inserted into the accommodating cavity 310, the end of the circuit board 32 is inserted under the limit insert tongue 313 in an inclined manner, and then the circuit board 32 is pressed downwards, so that the circuit board 32 is supported on the limit post 315, and the limit buckle 314 is elastically deformed, and finally is clamped at the other end of the circuit board 32.

Referring to fig. 11, in some embodiments, the first housing 31 has an outer bottom surface 31c facing away from the housing 10 in the height direction Z of the housing 10, and the receiving cavity 310 is recessed toward the outer bottom surface 31c to form a protrusion 316 on the outer bottom surface 31 c. Wherein the boss 316 has a flange portion 312, i.e., the flange portion 312 is located on the boss 316.

The accommodating cavity 310 is concavely arranged towards the outer bottom surface 31c to form a protruding portion 316 on the outer bottom surface 31c, that is, the protruding portion 316 is formed only at the position on the outer bottom surface 31c corresponding to the accommodating cavity 310, so that the thickness of the whole first housing 31 is uniform, which would result in an excessively large overall volume of the first housing 31 and be unfavorable for the hidden design of the light guiding structure 30 installed behind the housing 10. Therefore, by concavely providing the accommodating cavity 310 with the protruding portion 316, the accommodating cavity 310 can be utilized to embed the circuit board 32 to realize the protection effect on the circuit board 32, and meanwhile, the volume of the whole light guiding structure 30 can be reduced, which is more beneficial to the appearance effect of the light guiding structure 30 mounted on the housing 10.

In addition, the accommodating cavity 310 is concavely formed toward the outer bottom surface 31c to form a protrusion 316 on the outer bottom surface 31c, and since the circuit board 32 is disposed in the accommodating cavity 310, the remote control receiving head is disposed on the circuit board 32, and the flange 312 is formed on the protrusion 316 to better correspond to the remote control receiving head on the circuit board 32, so that the structural layout is more reasonable.

The outer bottom surface 31c is an outer bottom surface 31c opposite to the inner bottom surface 31a of the housing cavity 310 in the height direction Z of the casing 10, and the outer bottom surface 31c is a surface of the first casing 31 facing the table top, for example, when the display device 100 is placed on the table top.

With continued reference to fig. 11, in some embodiments, the boss 316 includes a first portion 316a, the first portion 316a extending along the width direction Y of the housing 10, i.e., the first portion 316a may extend along the length direction of the first housing 31, thus enabling the receiving cavity 310 to have more space in that direction for accommodating a larger size circuit board 32.

In some embodiments, the boss 316 includes a second portion 316b, the second portion 316b being connected to a side of the first portion 316a proximate the front side 10a, the second portion 316b having a dimension in the width direction Y of the housing 10 that is less than the dimension of the first portion 316 a. Wherein the second portion 316b has a flange portion 312, i.e. the flange portion 312 has a second portion 316b, in particular the flange portion 312 is located on a side of the second portion 316b that is closer to the front side 10 a.

By dividing the boss 316 into two parts, the second part 316b is connected to the side of the first part 316a near the front side 10a, and the size of the second part 316b in the width direction Y of the housing 10 is smaller than that of the first part 316a, so that the boss 316 is approximately in a shape of a "convex" shape, and thus, after the first housing 31 is mounted on the housing 10, the second part 316b with a small size is disposed closer to a user while ensuring the arrangement and performance of the circuit board 32, and the exposed volume of the first housing 31 can be visually reduced, thereby being more beneficial to the appearance improvement.

In addition, the protruding portion 316 is divided into two portions with different sizes, so that the mechanical performance can be optimized, the first portion 316a can provide main support when the circuit board 32 adapted to the accommodating cavity 310 is mounted, and the protruding flange portion 312 is formed on the second portion 316b with a smaller size, so that the protruding flange portion 312 can improve the light sensation and reduce the influence of protruding on the appearance. Meanwhile, the protruding portion 316 with the structural form is convenient for demoulding of an injection mould in the forming process, and the manufacturing yield is improved.

In some embodiments, a first connection structure is provided on the housing 10, the first connection structure being configured to be adapted to connect light guiding structures 30 having different functions. That is, the display device 100 provided by the present application can be compatible with light guiding structures 30 of different functions.

In this example, the boss 316 of the first housing 31 may also include a first portion 316a and a second portion 316b. And the circuit board 32 may be "convex" shaped to fit into the receiving cavity 310.
