[0043] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by any person skilled in the art without creative effort belong to the scope of protection of the present application.

[0044] In the description of the present application, it needs to be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0045] "A and / or B" includes the following three combinations: only A, only B, and a combination of A and B.

[0046] The use of "adapted to" or "configured to" in the present application means open and inclusive language that does not exclude devices adapted to or configured to perform additional tasks or steps. In addition, the use of "based on" means open and inclusive, because the process, step, calculation or other action "based on" one or more stated conditions or values can be based on additional conditions or values beyond those stated in practice.

[0047] In the present application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described as "exemplary" in the present application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the present application. In the following description, for the purposes of explanation, numerous details are set forth. It should be appreciated that one of ordinary skill in the art will realize that the present application can be practiced without the use of these specific details. In other instances, well known structures and processes are not elaborated in order not to obscure the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0048] At present, the existing display devices, such as televisions, computer displays and the like, especially televisions, are developing towards thinness and seamless wall pasting. How to reduce the thickness of the television without increasing the cost has been the goal pursued by the technical personnel in the field.

[0049] Especially for the current frameless or thin-frame televisions, the screen fullness rate is high. For this part of the television, due to the small installation space at the frame, the function module 1 such as the sound box, the power supply and the core can only be installed in the installation cavity formed between the back plate 2 and the shell 4. Please refer to Figures 1 to 4 The conventional method for this part of the television is generally to fully pave the light bar 4 on the back plate 2, and then to stack the function module 1 such as the sound box, the power supply and the core with the light bar 2 in the thickness direction of the television. At this time, the thickness value of the whole machine is the maximum value of the thickness of the backlight module, the thickness of the sound box or the power supply or the core, the safety distance reserved by the whole machine and the thickness of the rear shell; the maximum value of the thickness of the sound box or the power supply or the core directly constitutes a part of the thickness of the whole machine.

[0050] For this, please refer to Figures 5 to 9 The display device 100 provided by the present application comprises a shell 10, a backlight module 20, a display panel and a function module 30. The backlight module 20 is installed in the shell 10. The function module 30 is installed in the shell 10, and the function module 30 and the light bar 21 of the backlight module 20 are arranged in a staggered manner in the projection of the display panel.

[0051] It should be noted that the specific implementation form of the function module 30 is not limited, which can be a sound box, a power supply, a core, a multi-in-one module and the like, which is not limited here.

[0052] The function module 30 and the light bar 21 are arranged in a staggered manner in the projection of the display panel. Specifically, the function module 30 can be installed on the upper side, the lower side, the left side or the right side of the light bar 21, which is not limited here, as long as the function module 30 and the light bar 21 do not overlap in the thickness direction of the display device 100.

[0053] It should be emphasized that in the prior art, one or more components such as the main board, the power supply and the sound box can be separated from the installation cavity of the display device 100 and made into a split box to reduce the thickness of the whole machine. However, due to the increase in the number of various components such as the connection cable and the split box structure, the cost will also increase. In the present embodiment, the function module 30 is still installed in the shell 10, so that the cost will not increase.

[0054] The function module 30 and the lamp strip 21 are arranged in a staggered manner on the display panel, that is, the function module 30 and the lamp strip 21 originally overlapping in the thickness direction are dispersed, so that the function module 30 and the lamp strip 21 no longer overlap in the thickness direction of the display device 100, and the thickness of the display device 100 can be smaller.

[0055] At this moment, if the function module 30 does not protrude the lamp strip 21 in the thickness direction, the thickness of the whole machine is equal to the thickness of the module, plus the gap and safety distance between the rear shell 12 and the back plate 22, plus the thickness of the rear shell 12. Compared with the existing scheme, the function module 30 no longer affects the maximum thickness of the whole machine, thereby greatly reducing the thickness of the whole machine. For example, the straight-down type whole machine of OD25, the thickness of the whole machine arranged by the traditional scheme is about 63mm-65mm, and the thickness of the whole machine arranged by the present scheme is less than 50mm. The cost of the two is equivalent, and the thickness of the display device 100 can be reduced without increasing the cost.

[0056] Specifically, please refer to Figure 6 In a further embodiment, the backlight module 20 includes a back plate 22, the length direction or the width direction of the display panel is a first direction, the back plate 22 includes a plurality of mounting portions arranged in sequence along the first direction, the plurality of mounting portions include a lamp strip mounting portion 23 and a device mounting portion 24, the lamp strip mounting portion 23 is used for mounting the lamp strip 21, and the device mounting portion 24 and the shell 10 define a device mounting cavity used for mounting the function module 30; along the first direction and in the direction away from the lamp strip mounting portion 23, the size of the device mounting cavity in the thickness direction of the backlight module 20 is gradually increased.

[0057] It should be noted that the lamp strip 21 is mounted on the lamp strip mounting portion 23, which can provide a backlight source for the backlight module 20, and the first direction is arranged in overlap or parallel with the display panel. For example, the front and back directions in the thickness direction, the first direction can be left and right directions, or up and down directions, which are not limited here.

[0058] In the present embodiment, along the first direction and in the direction away from the lamp strip mounting portion 23, the size of the device mounting cavity in the thickness direction of the backlight module 20 is gradually increased, so that the depth of the device mounting cavity can be gradually increased in the direction away from the lamp strip mounting portion 23. Compared with the scheme without increasing, the space of the device mounting cavity is larger, and more function modules 30 can be accommodated, so that the thickness of the display device 100 is smaller.

[0059] Specifically, taking the case that the first direction is the up-down direction and the device mounting portion 24 is located above the light bar mounting portion 23, the depth of the device mounting cavity is larger from top to bottom, so that the space is larger and the number of functional modules 30 that can be accommodated is larger.

[0060] It should be emphasized that the size of the device mounting cavity in the thickness direction of the backlight module 20 gradually increases. Taking the case that the first direction is the width direction of the display panel, i.e., the up-down direction, and the device mounting portion 24 is located above the light bar mounting portion 23, the device mounting portion 24 can be inclined in the upward direction to form the display side of the backlight module 20. Specifically, the device mounting portion 24 can be a straight plate, a curved plate, or a multi-segment plate, etc. The same applies when the device mounting portion 24 is located below the light bar mounting portion 23. The device mounting portion 24 is inclined in the downward direction to the display side of the backlight module 20, so that the size of the device mounting cavity in the thickness direction of the backlight module 20 gradually increases. Similarly, the device mounting portion 24 can also be arranged on the left and right sides of the light bar mounting portion 23.

[0061] It can be understood that the larger the size of the light bar mounting portion 23, the smaller the volume of the device mounting cavity, and the smaller the size of the light bar mounting portion 23, the larger the volume of the device mounting cavity. Therefore, in an embodiment, the projection area of the back plate 22 in the thickness direction of the display device 100 is A, and the projection area of the light bar mounting portion 23 in the thickness direction of the display device 100 is a, wherein 20%≤a / A≤60%.

[0062] In the scheme of the present embodiment, a / A is greater than or equal to 20%, so that at least 20% of the area can be arranged with light bars 21 to provide sufficient light sources for the backlight module 20 and ensure the display effect of the display device 100. And a / A is less than or equal to 60%, so that the back plate 22 has enough area for the device mounting portion 24 to be arranged, and a device mounting cavity of sufficient size is formed to accommodate a sufficient number of functional modules 30 in the device mounting cavity, thereby reducing the overall thickness of the display module.

[0063] It should be emphasized that the LED lights included in the light bar 21 can be arranged in a forward direction or in a reverse direction, without limitation.

[0064] Specifically, since the area ratio of the lamp strip mounting portion 23 on the back plate 22 in the present application is smaller than that of the existing lamp strip mounting portion 23, the volume of the device mounting cavity can be larger, which will inevitably reduce the number of lamp strips 21 installed. Therefore, in order to ensure the display effect of the display device 100, in a further embodiment, the lamp strip 21 is provided with an LED lamp, and the LED chip of the LED lamp is flip-chip mounted.

[0065] It should be noted that the LED chip of the LED lamp mounted in a normal way will shield light due to the pins and other parts on the outside, resulting in poor light output and small diffusion angle. In the present application, the LED chip is flip-chip mounted, so that the diffusion angle of the LED lamp is larger, and compared with the current normal mounting scheme, fewer lamp strips 21 can be used to achieve the same or better display effect.

[0066] In a further embodiment, the design and manufacturing process of the lens can be improved, and the shape and angle of the refractive surface and the reflective surface of the lens can be optimized to allow light to be opened at a larger angle while ensuring uniformity, so that fewer lamp strips 21 can be used to achieve the same or better display effect, compress the area ratio of the lamp strip mounting portion 23, and reduce the overall thickness of the display device 100.

[0067] It can be understood that the device mounting portion 24 can be provided with only one or multiple. Since the light emitted by the lamp strip 21 on the lamp strip mounting portion 23 is diffused in all directions, in an embodiment, the device mounting portion 24 is provided with at least two, and the at least two device mounting portions 24 are arranged at the two ends of the lamp strip mounting portion 23 in the first direction. In this way, the device mounting portion 24 is provided with at least two, so that at least two device mounting cavities can be formed in the display device 100. Compared with the single device mounting cavity scheme, more device mounting cavities can be formed, so that the area other than the lamp strip mounting portion 23 has more space for installing the functional module 30, and the thickness of the display device 100 is smaller.

[0068] Specifically, it is emphasized that the device mounting portion 24 is provided with at least two, which can be provided with two, for example, provided on the upper and lower sides of the lamp strip mounting portion 23, or provided on the left and right sides of the lamp strip mounting portion 23, or provided with three, for example, provided on the upper and lower sides of the lamp strip mounting portion 23 and one side of the left and right sides, or provided on the left and right sides of the lamp strip mounting portion 23 and one side of the upper and lower sides, of course, the device mounting portion 24 can also be provided with four, provided on the upper, lower, left and right sides of the lamp strip mounting portion 23, which is not limited here.

[0069] Further, in an embodiment, the first direction is the up-down direction; the two device mounting portions 24 include a first device mounting portion 24 located above the lamp strip mounting portion 23 and a second device mounting portion 24 located below the lamp strip mounting portion 23, the first device mounting portion 24 and the shell 10 define a first device mounting cavity 25, and the second device mounting portion 24 and the shell 10 define a second device mounting cavity 26; the functional module 30 includes a sound box, a power supply, and a movement, and the power supply and the movement are installed in the second device mounting cavity 26.

[0070] Corresponding to the technical solution in this embodiment, the power supply and the movement are installed in the second device mounting cavity 26, that is, close to the bottom position of the display device 100, on the one hand, it is close to the bottom heat dissipation hole and can directly exchange heat with the bottom heat dissipation hole, the heat dissipation effect of the power supply and the movement is better, on the other hand, it is convenient for users to operate.

[0071] And at this time, the size of the display device 100 is less than or equal to the critical size, and the sound box is installed in the first device mounting cavity 25.

[0072] Corresponding to this embodiment, since the size of the display device 100 is less than or equal to the critical size, the overall size of the display device 100 is smaller at this time, on the one hand, considering the size of the space in the second mounting cavity, after installing the power supply and the movement and other components, if the sound box is also installed in the second mounting cavity, the second mounting cavity must be made larger at this time, which will increase the overall thickness of the display device 100 to a certain extent, therefore, installing the sound box in the first mounting cavity can further reduce the overall thickness of the display device 100.

[0073] On the other hand, since the sound box is installed in the first device mounting cavity 25, it is above the lamp strip mounting portion 23 and above the whole display device 100. In daily use, the display device 100 is generally placed on a cabinet or a table. At this time, since the sound box is far away from the bottom of the display device 100, the sound emitted by the sound box is not easily reflected by the cabinet or the table, so that the sound quality and tone of the sound emitted by the display device 100 are better.

[0074] In another embodiment, the size of the display device 100 is greater than the critical size, and the sound box is installed in the second device mounting cavity 26. In this embodiment, the size of the display device 100 is greater than the critical size. At this time, the size of the corresponding display device 100 is large, and the size of the second device mounting cavity 26 can also be large without affecting the thickness of the whole machine. After the power supply, the core and other components are installed, the sound box can be installed without affecting the thickness of the whole machine.

[0075] In addition, at this time, the sound box is installed in the second device mounting cavity 26, which is close to the bottom of the display device 100. In daily use, it is close to the cabinet or the table, so that the sound emitted by the sound box can be reflected by the cabinet or the table. The reflected sound wave is superimposed on the sound wave emitted by the sound box, so that the volume of the sound emitted by the display device 100 is larger.

[0076] It should be emphasized that the selection of the critical size is not limited and can be any size, such as 30 inches, 35 inches, 40 inches, etc. In further embodiments, the critical size is 45 inches to 55 inches. It can be understood that when the critical size is 55 inches, if the display device 100 is greater than 55 inches, it is generally placed in a room with a large space. At this time, the sound box is installed in the second device mounting cavity 26, which can increase the volume of the sound emitted by the display device 100, giving users a better experience. When the size of the display device 100 is less than or equal to 45 inches, the sound box is installed in the first device mounting cavity 25, so that the sound emitted by the sound box is not reflected, which affects the tone and sound quality of the sound.

[0077] Specifically, in this embodiment, the critical size can be any value between 45 inches and 55 inches, such as 45 inches, 50 inches, 55 inches, etc. without limitation.

[0078] In other embodiments, the first direction is the length direction of the display panel, i.e. the left-right direction when the display panel is hung on a wall; two third device mounting cavities are defined between the two device mounting portions 24 and the shell 10; and the functional module 30 includes at least two sound boxes, and the at least two sound boxes are arranged in the two third device mounting cavities.

[0079] In this embodiment, the two sound boxes are arranged in the two third device mounting cavities, i.e. placed on the left and right sides of the display device 100. Generally, no objects are placed on the left and right sides of a television, so that the reflection of sound emitted by the sound boxes caused by external objects can be reduced to the greatest extent, and as much sound as possible can be emitted from the sound boxes directly to the ears of the user, so that the sound quality and timbre of the sound emitted by the display device 100 are better.

[0080] It should be noted that the functional module 30 is mounted in the device mounting cavity, which can be mounted on the shell 10 or the device mounting portion 24, and is not limited herein. Figure 8 9 The functional module 30 is mounted in the device mounting cavity, which can be mounted on the shell 10 or the device mounting portion 24, and is not limited herein.

[0081] It should be noted that if part of the functional module 30 is mounted on the shell 10 and part of the functional module 30 is mounted on the device mounting portion 24, the functional module 30 will be staggered or partially overlapped in the thickness direction of the display device 100, thereby hindering the flow of heat dissipation air flow and affecting the heat dissipation effect of the display device 100.

[0082] In further embodiments, the functional module 30 is mounted on the device mounting portion 24. In this way, a smooth heat dissipation channel can be formed between the functional module 30 and the shell 10, so that the heat-exchanged gas can be smoothly discharged to the outside of the display device 100. Moreover, since part of the functional module 30 originally overlaps the light bar 21, it no longer overlaps the functional module 30 at this time, which can reduce the hindering effect of the heat dissipation air flow to a certain extent, make the heat dissipation air flow run more smoothly, and improve the heat dissipation effect of the display device 100.

[0083] It can be understood that the backlight module 20 can have one light bar mounting portion 23 or multiple light bar mounting portions 23, which is not limited herein.

[0084] Taking the two light bar mounting portions 23 commonly seen at present as an example, please refer to Figure 7 ​When multiple lamp strip mounting portions 23 are provided, compared with a single lamp strip mounting portion 23, the number of bending of the back plate 22 is increased, which leads to the reduction of the strength, and the problem of poor uniformity caused by the lamp strip 21 on the multiple lamp strip mounting portions 23;

[0085] Therefore, please refer to Figure 6 In an embodiment, the back plate 22 is provided with only one lamp strip mounting portion 23, and the shell 10 includes a rear shell 12 and a middle frame 11 provided on the side of the rear shell 12, and the device mounting portion 24 extends to be connected with the middle frame 11.

[0086] Corresponding to the technical solution in the embodiment, since the back plate 22 is provided with only one lamp strip mounting portion 23, the number of bending of the back plate 22 is small, and the strength is high. Compared with the scheme of multiple lamp strip mounting portions 23, the device mounting portion 24 extends to be connected with the middle frame 11, so that a larger device mounting cavity can be formed. When the functional module 30 is installed in the device mounting cavity, more space is left for the heat dissipation airflow to pass through, so that the heat dissipation effect is better.

[0087] Further, the distance between the lamp strip mounting portion 23 and the shell 10 in the thickness direction of the display device 100 cannot be too large, otherwise it will affect the overall thickness of the display device 100, and cannot be too small. If it is too small, the space left for the heat dissipation airflow to pass through is too small, which affects the overall heat dissipation of the display device 100. Therefore, in an embodiment, the distance between the lamp strip mounting portion 23 and the shell 10 in the thickness direction of the display device 100 is b, and 5mm≤b≤30mm.

[0088] In the technical solution of the embodiment, b is less than or equal to 30mm, so as to ensure the overall thickness. Since part of the functional module 30 installed on the lamp strip mounting portion 23 is moved to the device mounting cavity, when the value of b is smaller than or equal to the existing value, the heat dissipation effect of the display device 100 can be better, and when b is greater than or equal to 5mm, enough space is ensured for the heat dissipation airflow to pass through, so as to ensure the heat dissipation effect of the overall display device 100.

[0089] Further, the functional module 30 includes one or more of a sound box, a power supply, a movement, and an all-in-one module. It can be understood that the overall size of the sound box, the power supply, the movement, and the all-in-one module is relatively large. When they are installed on the lamp strip mounting portion 23, the overall thickness of the display device 100 will be greatly affected. Therefore, when they are installed in a staggered manner with the lamp strip 21, the overall thickness of the display device 100 can be greatly reduced.

[0090] The specific implementation form of the display device 100 is not limited, and can be a display, a television, or the like. The technical solution provided in the present application is best used on a television, and therefore, in an embodiment, the display device 100 includes a television.

[0091] The display device 100 provided in the embodiments of the present application is described in detail above, and specific examples are applied herein to describe the principles and implementation manners of the present application. The above description of the embodiments is only used to help understand the method of the present application and the core idea thereof. Meanwhile, for those skilled in the art, the specific implementation manners and application ranges will be changed according to the idea of the present application. In summary, the content of the specification should not be understood as a limitation on the present application.
