The following description is presented to enable any person skilled in the art to make and use the disclosure. In the following description, for the purpose of explanation, details are set forth. It is apparent to those skilled in the art that the disclosure can be practiced without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of the disclosure. Therefore, the disclosure is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed.

[0031] As shown in FIG. 1, the display device 1 provided by the embodiments of the disclosure can effectively prevent the optical component 20 from being deformed or damaged when it expands due to heat, thereby ensuring the light output quality of the display device 1 and the display visual effect of the display device. The use of the display device can be determined according to actual needs, which can be used as a complete machine or a display component with display function, such as a television, a display, a computer, a mobile phone, a tablet computer, etc. The embodiments of the disclosure do not limit this.

[0032] Here, the display device 1 comprises a back plate 10, an optical component 20 and a display panel 30. The back plate 10 has a bottom wall 11 and a side wall 12 arranged around the bottom wall 11, and the bottom wall 11 and the side wall 12 enclose a mounting cavity for mounting other components or devices. The optical component 20 is arranged on the bottom wall 11 so that the optical component 20 is located in the mounting cavity of the back plate 10. The display panel 30 is arranged on the side of the optical component 20 away from the bottom wall 11, and the optical component 20 is provided with a fixing member 70, and the display panel 30 is directly fixed to the optical component 20 by the fixing member 70, so that the bottom wall 11 can support the display panel 30 through the optical component 20 and the fixing member 70.

[0033] In this way, the back plate 10 does not need to be provided with a folding edge portion for supporting the display panel 30 and a separation protection member for separating the folding edge portion and the optical component 20, but the display panel 30 is supported by the bottom wall 11 and the optical component 20, which can simplify the structure of the back plate 10, thereby reducing the manufacturing difficulty and cost of the back plate and the whole machine.

[0034] The structure of the optical component 20 can be determined according to actual needs, and can include one or more types of, for example, a diffusion plate, an optical film, etc., which are not limited in the embodiments of the present disclosure.

[0035] In some embodiments, the display device 1 can further comprise an elastic buffer 40 arranged between the peripheral side of the optical component 20 and the side wall 12 of the back plate 10 to form a buffer separation between the optical component 20 and the side wall 12 of the back plate 10. When the display device 1 emits light, the optical component 20 expands due to the heat absorbed from the light source, and the surface size of the optical component 20 increases so that the peripheral side surface of the optical component 20 gradually approaches the side wall 12 of the back plate 10; in this process, the peripheral side surface of the optical component 20 first presses the elastic buffer 40 to elastically deform and compress the elastic buffer 40, and the elastic compression of the elastic buffer 40 releases a certain space on the peripheral side of the optical component 20, so that the optical component 20 can safely expand along the released space, avoiding the optical component 20 from being deformed or even damaged due to space compression, and ensuring that the optical component 20 remains flat and intact, thereby ensuring the light emission quality of the display device 1 and the display visual effect of the display device.

[0036] The material of the elastic buffer 40 can be determined according to actual needs, which is not limited in the embodiments of the present disclosure. In some embodiments, the elastic buffer 40 can be a foam member or a rubber member; these materials have better elasticity, so that the elastic buffer 40 can be compressed and deformed to a greater extent, thereby providing sufficient expansion space for the optical component 20.

[0037] The shape of the bottom wall 11 can be determined according to actual needs, and embodiments of the present disclosure do not limit the same. In some embodiments, the bottom wall 11 can include a lower wall portion 111, an inclined wall portion 112, and an upper wall portion 113 connected in sequence. The inclined wall portion 112 is arranged obliquely around the edge of the lower wall portion 111, and the inclined wall portion 112 and the lower wall portion 111 are obliquely angled. The upper wall portion 113 is arranged obliquely around the edge of the inclined wall portion 112 away from the lower wall portion 111, and the inclined wall portion 112 and the upper wall portion 113 are also obliquely angled. The side wall 12 is arranged around the edge of the upper wall portion 113 away from the inclined wall portion 112, the optical component 20 is arranged on the upper wall portion 113, and the optical component 20 is arranged opposite the lower wall portion 111, and the display panel 30 can be arranged on the side surface of the optical component 20 away from the upper wall portion 113. In some examples, the lower wall portion 111 and the upper wall portion 113 can be arranged in parallel; in other examples, the lower wall portion 111 and the upper wall portion 113 can be arranged obliquely. When the display device 1 further includes the elastic buffer 40, the elastic buffer 40 can be arranged on the upper wall portion 113.

[0038] The shape of the side wall 12 can be determined according to actual needs, and embodiments of the present disclosure do not limit the same. In some embodiments, the side wall 12 can include an outer side wall portion 121 and a bent wall portion 122 connected in sequence. The outer side wall portion 121 is connected at one end to the bottom wall 11, and the bent wall portion 122 is formed at the edge of the outer side wall portion 121 away from the bottom wall 11; the bent wall portion 122 extends toward the bottom wall 11, and the bent wall portion 122 and the bottom wall 11 are arranged in a spaced manner to form a gap region. The bent wall portion 122 can be arranged around the display panel 30, and a fitting gap is formed between the bent wall portion 122 and the display panel 30. By arranging the side wall 12 of the back plate 10 as above, the structure and manufacturing process of the back plate 10 can be simplified, and the manufacturing difficulty and cost of the back plate 10 can be reduced. When the display device 1 further includes the elastic buffer 40, the edge portion of the elastic buffer 40 can be embedded in the gap region between the bent wall portion 122 and the bottom wall 11.

[0039] In some embodiments, the display device 1 can further include a reflective sheet 50. The optical component 20 and the reflective sheet 50 are arranged in sequence on the bottom wall 11, and the reflective sheet 50 and the bottom wall 11 are arranged in abutment. In this way, the optical component 20 is located on the side of the reflective sheet 50 away from the bottom wall 11. The reflective sheet 50 can reflect the light rays irradiated toward the bottom wall 11, so that the light rays are reflected to the optical component 20, and then emitted forward after passing through the optical component 20, thereby improving the light emitting efficiency and light utilization rate of the display device 1.

[0040] In some examples, the optical component 20 can have a main light-transmitting portion 21 and an edge light-transmitting portion 22 surrounding the main light-transmitting portion 21. Here, the main light-transmitting portion 21 and the reflective sheet 50 coincide in position, i.e., the main light-transmitting portion 21 and the reflective sheet 50 coincide in orthographic projection on the plane where the reflective sheet 50 is located; and the edge light-transmitting portion 22 is located outside the range where the reflective sheet 50 is located, and the edge light-transmitting portion 22 and the bottom wall 11 are oppositely spaced, i.e., the edge light-transmitting portion 22 and the reflective sheet 50 do not overlap in orthographic projection on the plane where the reflective sheet 50 is located. The elastic buffer 40 is arranged between the edge light-transmitting portion 22 and the side wall 12, and the edge light-transmitting portion 22 and the elastic buffer 40 are in contact and interact when the optical component 20 is heated and expands.

[0041] For example, the display device 1 can include an adhesive layer 60 having a ring structure, and the edge light-transmitting portion 22 of the optical component 20 and the bottom wall 11 of the back plate 10 are fixedly bonded by the adhesive layer 60. In this way, a reliable bonding relationship between the edge light-transmitting portion 22 and the bottom wall 11 can be formed, and the degree of thermal expansion of the optical component 20 can be reduced to a certain extent by the bonding force, and the optical component 20 can be prevented from arching when the optical component 20 is about to arch, thereby better ensuring the flatness of the optical component 20.

[0042] The material of the adhesive layer 60 can be determined according to actual needs, and various transparent optical adhesives can be used, which are not limited in the embodiments of the present disclosure. For example, the adhesive layer 60 can be a reflective adhesive layer. In this way, the adhesive layer 60 has a better reflection effect on light, and when the light passes through the edge light-transmitting portion 22 and shines on the adhesive layer 60, the adhesive layer 60 can reflect the light, so that the light is reflected to the optical component 20 and then outwards, thereby improving the light-emitting efficiency and light utilization of the display device 1.

[0043] The number of the elastic buffers 40 arranged in the display device 1 can be determined according to actual needs, which is not limited in the embodiments of the present disclosure. In some embodiments, the display device 1 can include a plurality of elastic buffers 40, and the plurality of elastic buffers 40 are sequentially arranged along the circumference of the optical component 20. In this way, the plurality of elastic buffers 40 can form a surrounding barrier between the circumferential side of the optical component 20 and the side wall 12 of the back plate 10, so that each side surface of the optical component 20 along the circumference is provided with an elastic buffer 40; when the optical component 20 is heated and expands, the elastic buffer 40 can be elastically deformed and compressed under the expansion force of the optical component 20, thereby providing an expansion space for the optical component 20, so as to avoid arching and deformation of the optical component 20 and even damage, and to ensure the structural safety of the optical component 20 and the backlight quality of the display device 1.

[0044] In some embodiments, the fixing member 70 can be arranged at the edge of the optical component 20. The material of the fixing member 70 can be determined according to actual needs, and various transparent optical adhesives can be used, and the embodiments of the present disclosure are not limited in this regard. In some embodiments, the fixing member 70 can be an adhesive tape used to adhesively fix the optical component 20 and the display panel 30. In this way, a reliable adhesively fixed relationship between the display panel 30 and the optical component 20 can be achieved, thereby ensuring the structural reliability of the display device.

[0045] The display device provided by the embodiments of the present disclosure is described in detail above, and specific examples are applied herein to describe the principles and implementation manners of the present disclosure. The above description of the embodiments is only used to help understand the method of the present disclosure and its core idea; meanwhile, for those skilled in the art, the specific implementation manners and application ranges will be changed according to the idea of the present disclosure. In summary, the content of the description should not be understood as a limitation of the present disclosure.
