It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0049] Currently, existing display devices, such as televisions and computer monitors, especially televisions, are constantly evolving towards thinner and seamless wall-mounted designs. How to reduce the overall thickness of televisions without increasing costs has always been a goal pursued by those skilled in the art.

[0050] Especially with current frameless or thin-bezel TVs, the screen coverage is relatively high. For these TVs, due to the limited installation space at the bezel, functional modules 1 such as speakers, power supplies, and chassis can only be installed in the mounting cavity formed between the back panel 2 and the housing 4 (see Figures 1 to 4). The current common practice for these TVs is to fully cover the back panel 2 with light strips 4, and then stack the functional modules 1 such as speakers, power supplies, and chassis with the light strips 2 in the thickness direction of the TV. Correspondingly, the thickness of the entire unit is the thickness of the backlight module, plus the maximum thickness of the speaker, power supply, or chassis, plus the safety distance reserved for the entire unit, plus the thickness of the back shell; the maximum thickness of the speaker, power supply, or chassis directly constitutes part of the thickness of the entire unit.

[0051] Referring to Figures 5 to 9, this application provides a display device 100, which includes a housing 10, a backlight module 20, a display panel, and a functional module 30. The backlight module 20 is installed inside the housing 10; the functional module 30 is installed inside the housing 10, and the projection of the functional module 30 and the lamp strip 21 of the backlight module 20 onto the display panel is offset.

[0052] It should be noted that the specific implementation form of the functional module 30 is not limited, and it can be a speaker, power supply, mechanism, multi-in-one module, etc., which are not limited here.

[0053] The functional module 30 and the light strip 21 are offset from each other on the display panel. Specifically, the functional module 30 can be installed on the upper side, lower side, left side, right side, etc. of the light strip 21. There is no limitation here, as long as it does not overlap with the light strip 21 in the thickness direction of the display device 100.

[0054] It should be emphasized that, in the present invention, a split box can be used to separate one or more components such as the motherboard, power supply, and speakers from the mounting cavity of the display device 100 and make a split box, thereby reducing the thickness of the whole machine. However, due to the increase in the number of connecting cables, split box structural components and other components, the cost will also increase to a certain extent. In this embodiment, the functional module 30 is still installed in the housing 10, so there is no increase in cost.

[0055] In this embodiment, the functional module 30 and the light strip 21 are projected onto the display panel in a staggered manner. That is, the functional module 30 and the light strip 21, which originally overlapped in the thickness direction, are dispersed so that they no longer overlap in the thickness direction of the display device 100, thereby making the thickness of the display device 100 smaller.

[0056] At this moment, assuming that the functional module 30 does not protrude from the light strip 21 in the thickness direction, the thickness of the whole device is equal to the thickness of the module plus the gap and safety distance between the back shell 12 and the back plate 22, plus the thickness of the back shell 12. Compared with the existing solution, the functional module 30 no longer affects the maximum thickness of the whole device, thereby greatly reducing the thickness of the whole device. Taking the OD25 direct-lit whole device as an example, the thickness of the whole device arranged with the traditional solution is about 63mm to 65mm, while the thickness of the whole device arranged with this solution is within 50mm. At the same time, the cost of the two is comparable, and the thickness of the display device 100 can be reduced without increasing the cost.

[0057] Specifically, please refer to Figure 6. In a further embodiment, the backlight module 20 includes a back plate 22. Taking the length or width direction of the display panel as the first direction, the back plate 22 includes a plurality of mounting portions arranged sequentially along the first direction. The plurality of mounting portions include a light strip mounting portion 23 and a device mounting portion 24. The light strip mounting portion 23 is used for mounting the light strip 21. The device mounting portion 24 defines a device mounting cavity between itself and the housing 10 for mounting the functional module 30. Along the first direction and in the direction away from the light strip mounting portion 23, the size of the device mounting cavity in the thickness direction of the backlight module 20 is gradually increased.

[0058] It should be noted that the light strip 21 is installed on the light strip mounting part 23 and can provide a backlight source for the backlight module 20. The first direction is overlapped or parallel to the display panel. Taking the thickness direction as the front-to-back direction as an example, the first direction can be left-to-right or up-to-down, which is not limited here.

[0059] In this 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. This allows the depth of the device mounting cavity to gradually increase in the direction away from the lamp strip mounting portion 23. Compared to the solution without increasing the depth, the device mounting cavity has a larger space, can accommodate more functional modules 30, and makes the thickness of the display device 100 smaller.

[0060] Specifically, taking the first direction as the vertical direction, and taking the device mounting part 24 as being located above the light strip mounting part 23 as an example, the depth of the device mounting cavity increases as it goes up, thus making its space larger and able to accommodate more functional modules 30.

[0061] It should be emphasized that the device mounting cavity is arranged to gradually increase in size along the thickness direction of the backlight module 20. Taking the first direction as the width direction of the display panel, i.e., the vertical direction, and taking the device mounting part 24 as being above the lamp strip mounting part 23 as an example, the device mounting part 24 can be formed by tilting the entire device mounting part 24 upward toward the display side of the backlight module 20. Specifically, the device mounting part 24 can be a straight plate, a curved plate, or a multi-segment plate, etc., without limitation. Similarly, when the device mounting part 24 is located below the lamp strip mounting part 23, the device mounting part 24 is tilted downward toward the display side of the backlight module 20, thereby making the size of the device mounting cavity gradually increase in the thickness direction of the backlight module 20. By analogy, the device mounting part 24 can also be located on the left or right side of the lamp strip mounting part 23.

[0062] It is understood that the larger the size of the light strip mounting part 23, the smaller the corresponding volume of the device mounting cavity. Conversely, the smaller the size of the light strip mounting part 23, the larger the corresponding volume of the device mounting cavity can be. Therefore, in one embodiment, the projected area of ​​the back plate 22 in the thickness direction of the display device 100 is A, and the projected area of ​​the light strip mounting part 23 in the thickness direction of the display device 100 is a, wherein 20% ≤ a / A ≤ 60%.

[0063] In this embodiment, a / A is greater than or equal to 20%, ensuring that at least 20% of the area can be used to install the light strip 21, providing sufficient light source for the backlight module 20 and ensuring the display effect of the display device 100. Meanwhile, a / A is less than or equal to 60%, ensuring that there is enough area on the back plate 22 for the device mounting part 24 to be installed, forming a device mounting cavity of sufficient size, which can accommodate a sufficient number of functional modules 30, thereby reducing the overall thickness of the display module.

[0064] It should be emphasized that the LEDs included in the light strip 21 can have their chips mounted upright or upside down, and no limitation is made here.

[0065] Specifically, since the area ratio of the light strip mounting part 23 on the back plate 22 in this application is smaller than that of the existing light strip mounting part 23, the volume of the device mounting cavity can be larger. Correspondingly, the number of light strips 21 installed will inevitably be reduced. Therefore, in order to ensure the display effect of the display device 100, in a further embodiment, the light strip 21 is provided with LED lights, and the LED chips of the LED lights are flip-chip configured.

[0066] It should be noted that LEDs with upright LED chips have poor light emission and a small diffusion angle because the pins, packages and other components on the outside of the LED chip block the light. In this application, by flipping the LED chip, the diffusion angle of the LED is made larger. Compared with the current upright solution, fewer LED strips 21 can be used to achieve the same or better display effect.

[0067] In a further embodiment, the shape and angle design of the refractive and reflective surfaces of the lens can be optimized by improving the lens design and manufacturing process, so that the light can be opened at a larger angle while ensuring its uniformity. This allows for the use of fewer light strips 21 to achieve the same or better display effect, reduces the area ratio of the light strip mounting part 23, and reduces the overall thickness of the display device 100.

[0068] It is understood that the device mounting part 24 may be provided as one or multiple. Since the light emitted by the light strip 21 on the light strip mounting part 23 diffuses in all directions, in one embodiment, at least two device mounting parts 24 are provided. At least two device mounting parts 24 are respectively provided at both ends of the light strip mounting part 23 in the first direction. With this arrangement, at least two device mounting parts 24 are provided, thereby forming at least two device mounting cavities in the display device 100. Compared with a single device mounting cavity, it can form more device mounting cavities, thereby providing more space in the area other than the light board mounting part 23 to install the functional module 30, and making the thickness of the display device 100 smaller.

[0069] Specifically, it should be emphasized that at least two device mounting portions 24 are provided. They can be provided in two locations, for example, on the upper and lower sides of the light strip mounting portion 23, or on the left and right sides of the light strip mounting portion 23. They can also be provided in three locations, for example, on the upper and lower sides of the light strip mounting portion 23 and on one of the left and right sides, or on the left and right sides of the light strip mounting portion 23 and on one of the upper and lower sides. Of course, the device mounting portions 24 can also be provided in four locations, on the upper, lower, left, and right sides of the light strip mounting portion 23, respectively. This is not limited here.

[0070] Furthermore, in one embodiment, the first direction is the vertical direction; the two device mounting portions 24 include a first device mounting portion 24 located above the light strip mounting portion 23 and a second device mounting portion 24 located below the light strip mounting portion 23, the first device mounting portion 24 and the housing 10 define a first device mounting cavity 25, and the second device mounting portion 24 and the housing 10 define a second device mounting cavity 26; the functional module 30 includes a speaker, a power supply, and a mechanism, the power supply and the mechanism being mounted in the second device mounting cavity 26.

[0071] In the technical solution of this embodiment, the power supply and the mechanism are installed in the second device mounting cavity 26, which is close to the bottom of the display device 100. On the one hand, the heat dissipation holes near the bottom can directly exchange heat with the heat dissipation holes at the bottom, which improves the heat dissipation effect of the power supply and the mechanism. On the other hand, it is convenient for the user to operate them.

[0072] At this time, the size of the display device 100 is less than or equal to the critical size, and the speaker is installed in the first device mounting cavity 25.

[0073] In 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 relatively small. Considering the size of the space inside the second mounting cavity, if the speaker is to be installed inside the second mounting cavity after the power supply and other components are installed, the second mounting cavity will need to be made relatively large, which will increase the overall thickness of the display device 100 to a certain extent. Therefore, installing the speaker inside the first mounting cavity can further reduce the overall thickness of the display device 100.

[0074] On the other hand, since the speaker is installed in the first device mounting cavity 25, which is above the light strip mounting part 23 and also above the entire display device 100, the display device 100 is usually placed on a cabinet or table during daily use. At this time, since the distance between the speaker and the bottom of the display device 100 is relatively far, the sound emitted by the speaker is not easily reflected by objects such as cabinets or tables, making the sound quality and timbre of the sound emitted by the display device 100 better.

[0075] In another embodiment, the size of the display device 100 is larger than the critical size, and the speaker is installed in the second device mounting cavity 26. In the technical solution of this embodiment, the size of the display device 100 is larger than the critical size. At this time, the size of the display device 100 is relatively large, and the size of the second device mounting cavity 26 can also be made relatively large without affecting the thickness of the whole machine. After the power supply, mechanism and other components are installed, the speaker can also be installed without affecting the thickness of the whole machine.

[0076] Furthermore, at this time, the speaker is installed in the second device mounting cavity 26, which is close to the bottom of the display device 100. During daily use, it is close to the cabinet or table, so that the sound emitted by the speaker can be reflected by the cabinet or table. The reflected sound waves are superimposed with the sound waves emitted by the speaker, making the volume of the display device 100 louder.

[0077] It should be emphasized that the choice of the critical size is not limited and can be any size, such as 30 inches, 35 inches, 40 inches, etc., without limitation. In a further embodiment, the critical size is 45 inches to 55 inches. It can be understood that when the critical size is 55 inches, if our display device 100 is larger than 55 inches, it is generally placed in a relatively large room. At this time, installing the speaker in the second device mounting cavity 26 can increase the volume of the sound emitted by the display device 100 and give the user a better experience. When the size of the display device 100 is less than or equal to 45 inches, the display device 100 is generally placed in a relatively small room. At this time, it is not necessary to increase the volume of the speaker. The speaker is installed in the first device mounting cavity 25, thereby avoiding the reflection of its emitted sound waves, which would affect the timbre and sound quality.

[0078] 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., and is not limited here.

[0079] In other embodiments, the first direction is the length direction of the display panel, that is, the left and right direction when the display panel is hung on the wall; two device mounting parts 24 and the housing 10 define two third device mounting cavities; the functional module 30 includes at least two speakers, and the at least two speakers are respectively disposed in the two third device mounting cavities.

[0080] In this embodiment, the two speakers are respectively located in the two third device mounting cavities, that is, placed on the left and right sides of the display device 100. Generally speaking, there are usually no items placed on the left and right sides of a TV. Therefore, the reflection of the sound emitted by the speakers by external objects can be reduced to the greatest extent, and as much sound as possible can reach the user's ears directly after being emitted from the speakers, so that the sound quality and timbre of the sound emitted by the display device 100 are better.

[0081] It should be emphasized that, as shown in Figures 8 and 9, the functional module 30 is installed in the device mounting cavity, which can be installed on the housing 10 or on the device mounting part 24, and is not limited here.

[0082] It should be noted that if some functional modules 30 are installed in the housing 10 and some functional modules 30 are installed in the device mounting part 24, the functional modules 30 will be staggered or partially overlapped in the thickness direction of the display device 100, thereby hindering the flow of heat dissipation airflow and affecting the heat dissipation effect of the display device 100.

[0083] In a further embodiment, the functional module 30 is mounted on the device mounting portion 24. This arrangement forms a smooth heat dissipation channel between the functional module 30 and the housing 10, allowing the heat-exchanged gas to be smoothly discharged to the outside of the display device 100. Furthermore, since the functional module 30, which originally partially overlapped with the light strip 21, no longer overlaps with the functional module 30, the obstruction to the heat dissipation airflow is reduced to a certain extent, making the heat dissipation airflow smoother and improving the heat dissipation effect of the display device 100.

[0084] It is understood that the backlight module 20 may have one light strip mounting part 23 or may have multiple light strip mounting parts 23, and no limitation is made here.

[0085] Taking the two commonly used light strip mounting parts 23 as an example, please refer to Figure 7. When multiple light strip mounting parts 23 are provided, compared with a single light strip mounting part 23, the number of bends of the back plate 22 will increase, resulting in a decrease in its strength. Furthermore, the light strips 21 on multiple light strip mounting parts 23 will have poor uniformity.

[0086] Therefore, referring to Figure 6, in one embodiment, the back plate 22 is provided with only one light strip mounting part 23, and the housing 10 includes a rear shell 12 and a middle frame 11 disposed on the periphery of the rear shell 12, and the device mounting part 24 extends to be connected to the middle frame 11.

[0087] In the technical solution of this embodiment, since the back plate 22 is provided with only one light strip mounting part 23, the back plate 22 has fewer bends and higher strength. Furthermore, compared with the solution of multiple light strip mounting parts 23, the device mounting part 24 extends to connect with the middle frame 11, thereby forming a larger device mounting cavity. When the functional module 30 is installed in the device mounting cavity, more space can be left for heat dissipation airflow to pass through, thereby making its heat dissipation effect better.

[0088] Furthermore, the distance between the light strip mounting portion 23 and the housing 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. It also cannot be too small, otherwise the space left for heat dissipation airflow will be too small, affecting the overall heat dissipation of the display device 100. Therefore, in one embodiment, the distance between the light strip mounting portion 23 and the housing 10 in the thickness direction of the display device 100 is b, where 5mm ≤ b ≤ 30mm.

[0089] In the technical solution of this embodiment, b is less than or equal to 30mm, thereby ensuring the thickness of the whole machine. Furthermore, since some of the functional modules 30 installed on the lamp strip mounting part 23 are moved into the device mounting cavity, the heat dissipation effect of the display device 100 can be better when the value of b is smaller or the same as the existing value. When b is greater than or equal to 5mm, it ensures that there is enough space for the heat dissipation airflow to pass through, thus ensuring the heat dissipation effect of the display device 100 as a whole.

[0090] Furthermore, the functional module 30 includes one or more of the following: speaker, power supply, mechanism, and multi-function module. It is understood that the overall size of the speaker, power supply, mechanism, and multi-function module is relatively large. When they are installed in the light strip mounting part 23, they will greatly affect the overall thickness of the display device 100. Therefore, when they are installed in a staggered manner with the light strip 21, the overall thickness of the display device 100 can be greatly reduced.

[0091] The specific implementation of the display device 100 is not limited, and it can be a monitor, a television, etc. The technical solution provided in this application has the best effect when used on a television. Therefore, in one embodiment, the display device 100 includes a television.

[0092] The display device 100 provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
