The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram of a television according to an embodiment of the present application; FIG. 2 is a schematic diagram showing a comparison of the front-to-back variation of the second back plate portion of the television of FIG. 1; FIG. 3 is a right side view of the television set of FIG. 1; fig. 4 is a left side view of the television set of fig. 1.

In an embodiment, the television set provided by the present application includes a television main body, the television main body includes a display screen 103 and a back plate disposed on a back side of the display screen 103, and a plurality of backlight sources 104 are fixed on an inner wall of the back plate;

the back plate comprises a first back plate part 101 close to the top side and a second back plate part 102 close to the ground side; and the second back plate portion 102 is recessed towards the display screen 103 with respect to the first back plate portion 101 such that the distance between the second back plate portion 102 and the display screen 103 is smaller than the distance between the first back plate portion 101 and the display screen 103.

As shown in fig. 1, the television includes a television body and a base 111 supporting the television body. In the present application, the whole of the upper portion of the base 111 is defined as a tv main body. The television body comprises a display screen 103 and a back panel arranged on the back.

In the prior art, the back plate is an integral rectangular plate covering the back side of the display screen 103. In this application, however, the back plate comprises two parts: a first backplate portion 101 and a second backplate portion 102, both of which are generally rectangular, and the second backplate portion 102 is recessed inwardly with respect to the first backplate portion 101 so that the distance of the second backplate portion 102 from the display screen 103 is smaller than the distance of the first backplate portion 101 from the display screen 103.

In this configuration, since the second back plate portion 102 is recessed inward, the entire thickness of the second back plate portion 102 is smaller than that of the conventional design after various hardware components are mounted on the outside. Therefore, the structural design of the television can obviously reduce the overall thickness of the television and improve the experience of users.

As shown in fig. 1, a rear case 110 is provided outside the second back plate 102 and is mounted and closed. As shown in fig. 4, the television set includes a front case 112 and a display screen 103.

As shown in fig. 3, two speakers 107, a power supply board 105, a tcon board 108, a soc board 109, a main board 106, and other hardware structures are mounted on the outer side of the second back plate portion 102.

In the above structure, further improvements can be made. For example, the inner side of the back plate is covered with the same-shaped reflection sheet.

Referring to fig. 5, fig. 5 is a schematic view illustrating an installation position of each backlight 104 of the television set in fig. 3. In the above configuration, as shown in fig. 5, two backlights 104 are provided inside the first back plate portion 101, and one backlight 104 is provided inside the second back plate portion 102.

The distance from the backlight 104 on the second back plate 102 to the backlight of the display screen 103 was 15 mm. The backlight 104 on the first back plate portion 101 is at a distance of 35mm from the backlight of the display screen 103.

It should be noted that, in the above embodiment, a hybrid OD scheme (OD refers to a backlight distance) is adopted, an OD thickness of a region on the top side of the display backplane (i.e. the first backplane portion 101) is 35mm, an OD thickness of a region on the bottom side of the display backplane (i.e. the second backplane portion 102) is 15mm (excluding the rear housing 110, a light mixing distance inside the backplane, the backplane is irregular, the top side is thick, and the ground side is thin), an internal structure of the backplane is adjusted according to a contour shape of the backplane, and in order to ensure that the hybrid OD scheme can provide the backlight 104 with a uniform state the same as that of a single OD scheme in the prior art, an optical scheme is adjusted accordingly: the OD35 area adopts two reflective LED light bars 1 x 13 and 1 x 10, and the OD15 area adopts an optical scheme of the 1 x 13 reflective LED light bars; meanwhile, by compressing the thickness of the ground side module area, space is provided for installing components such as the power panel 105, the loudspeaker 107, the soc board 109, the main board 106, the tcon board 108 and the like, and the actual thickness of the whole machine is reduced.

Referring to fig. 6 and 7, fig. 6 is a schematic structural diagram of a television set in the prior art; fig. 7 is a right side view of the television set of fig. 6.

In this prior art, a single OD scheme is used, i.e. the backlight distance is OD30, i.e. the backlight distance is 30 mm. To explain this, the backlight distance refers to the distance from the backlight 104 to the display screen 103 in front of it. Since the backlight 104 is disposed on the inner side wall of the back plate, the distance between the back plate and the display screen 103 determines the OD distance. In this prior art, since a single OD scheme is adopted, that is, the distance from the top side and the bottom side of the back plate (corresponding to the first and second back plate portions 102 of the present invention) to the display screen 103 is the same. In this case, as shown in fig. 7, when various hardware is disposed on the outer sidewall of the ground-side back plate, the entire thickness thereof becomes larger.

The comparison between the thickness in the prior art and the thickness in the present application can be referred to fig. 8, and fig. 8 is a schematic diagram illustrating the comparison between the thickness of the tv set in fig. 1 and the thickness of the tv set in fig. 6.

In the present application, as shown in fig. 8, since a hybrid OD scheme, i.e., a scheme of OD35 and OD15 is adopted, this is explained: OD35, i.e. the distance of the backlight 104 from the display screen 103 on the first back plate part 101 towards the sky side, was 35 mm; OD15, i.e. on the second back plate part 102 on the ground side, the distance of the backlight 104 from the display screen 103 was 15 mm. Of course, this design of the hybrid backlight scheme can be implemented because the distance from the display screen 103 to the back plane as a whole is different in this application. Specifically, since the second back plate portion is once recessed with respect to the first back plate portion 101, the distance between the second back plate portion 102 and the display screen 103 is smaller than the distance between the first back plate portion 101 and the display screen 103.

As shown in fig. 8, when installed, the single OD solution adopted in the prior art has a thickness of 45mm on the top side and 78mm on the bottom side, and the overall thickness of the tv is 78 mm. In the present invention, the thickness of the television set is 50mm on the top side and 58mm on the bottom side, and thus the overall thickness of the television set is 58 mm. Obviously, the whole thickness of the television is reduced by 20mm by adopting the scheme of the invention.

That is, in the present application, a hybrid OD manner is adopted, a single OD30 scheme is changed into an OD35+ OD15 scheme (a light mixing distance refers to a light mixing distance of a light bar inside a backplane, and portions except the backplane, such as a rear case 110, components and the like), a thickness of a module ground region is compressed (where the module refers to a backplane, a reflector, a diffuser plate, a membrane and the like, which are all conventionally regular in shape, a plane structure and uniform placement of the light bar, a hybrid OD backplane and a reflector both adopt a step profile, and a light bar placement manner is changed), a module structure platform is reconstructed, although a local thickness is increased (45mm is increased to 50mm), an actual thickness of the whole machine is greatly reduced, and for a middle and low-end display product of OD30, the maximum whole machine thickness is expected to be reduced by 20mm, and a wall-hanging.

Referring to fig. 9 and 10, fig. 9 is an assembly view of the back housing 110 of the tv set of fig. 7; fig. 10 is an assembled view of the rear housing 110 of fig. 3, as viewed from the ground.

In the above embodiments, further designs may be made. For example, the television body further includes a power supply board 105, a main board 106, and a speaker 107, and the power supply board 105, the main board 106, and the speaker 107 are provided on an outer wall of the second back plate portion 102.

As shown in fig. 3, a speaker 107, a power supply board 105, a tocn board, a main board 106, and the like are arranged in line outside the second back plate portion 102 on the ground side. In contrast, as shown in fig. 7, in the conventional technique, the back plate on the ground side is in a chevron shape, the main board 106 and the power supply board 105 are disposed away from the bottom end, and the speaker 107 is located on the left and right.

Further, the rear housing 110 is covered on the outer side of the second back plate portion 102, and the power supply board 105, the main board 106 and the speaker 107 are located in a cavity surrounded by the rear housing 110 and the second back plate portion 102.

In the above embodiment, the rear case 110 may be specifically designed. For example, referring to fig. 10, the second back plate portion 102 extends from one side edge of the tv body to the other side edge, and is substantially rectangular; the rear housing 110 extends from one side edge of the television body to the other side edge and is generally rectangular. On the basis, the rear shell 110 is in a straight-line structure, and can adopt a left-right split structure.

Correspondingly, as shown in fig. 9, the rear housing 110 in the prior art is divided into an upper part and a lower part, and the upper part is small and the lower part is large.

In the above structure, as shown in fig. 3, the power supply board 105 is close to the bottom end of the tv body, and the power supply terminal port is led out from the bottom of the tv body; the main board 106 is close to the bottom end of the television body, and the signal connecting terminal port is led out from the bottom of the television body.

In the above technical solution, the layout of the hybrid OD scheme: by compressing the thickness of the local area of the ground side module, space is provided for installing hardware such as the main board 106, the power board 105, the speaker 107, and the like. Due to the limitation of a structural scheme, most external signal wires such as a power wire and an HDMI (high-definition multimedia interface) can adopt a side-out scheme or a back-out scheme, and when a user hangs a television for use, the phenomena of difficult terminal plugging, disordered wire outlet and the like exist, so that the user experience is seriously influenced; due to the structural advantage of the hybrid OD scheme, the power lines, the HDMI and other external signal lines can be uniformly plugged and unplugged on the ground (in the arrangement mode, the power panel 105, the mainboard 106 and the like are closer to the ground of the whole machine, and the terminal ports are more easily output from the ground), so that the terminal plugging and unplugging are facilitated, the outgoing line of the product is attractive, and the product experience of a user is greatly improved.

In addition, the hybrid OD solution splits the rear housing 110 into two halves, making the mold smaller and reducing the cost. The rear case 110 of the hybrid OD scheme employs a straight-line-shaped small rear case 110, and when the split rear case 110 scheme is employed, the rear case can be split into two parts with regular outline. However, in the single OD solution in the prior art, as shown in fig. 9, although the rear housing 110 originally has a split structure, it is a special-shaped split structure, so that the manufacturing cost is very high. And the mixed OD can ensure that two separated structures are more regular, the structure is simple, the processing difficulty of the die is lower, and the forming precision is easy to guarantee, so that the cost of the part is reduced.
