The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details.

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0025] like Figure 1 As shown, the embodiment of the present application provides a display device 1, which can effectively prevent the optical component 20 from being deformed or broken when it is heated and expanded, thereby ensuring the light output quality of the display device 1 and the display effect of the display device. The purpose of the display device can be determined according to actual needs, and can be used as a whole machine with display function such as a television, a monitor, a computer, a mobile phone, a tablet or a display component thereof, and the embodiment of the present application does not limit this.

[0026] Here, the display device 1 includes 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 a side of the optical component 20 away from the bottom wall 11, and a fixing member 70 is provided on the optical component 20. 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.

[0027] In this way, there is no need to set a folded edge portion for supporting the display panel 30 and an isolation protective piece for isolating the folded edge portion and the optical component 20 on the back panel 10. Instead, the display panel 30 is supported by the bottom wall 11 and the optical component 20. This can simplify the structure of the back panel 10, thereby reducing the difficulty and cost of manufacturing the back panel and the entire machine.

[0028] The structure of the optical component 20 can be determined according to actual needs, and may include one or more types such as a diffuser plate, an optical film, etc., which is not limited in the embodiment of the present application.

[0029] In some embodiments, the display device 1 may further include an elastic buffer 40, which is disposed between the periphery of the optical component 20 and the side wall 12 of the back plate 10 to form a buffer isolation 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 absorbs heat from the light source and expands, and the surface size of the optical component 20 increases so that the periphery surface of the optical component 20 gradually approaches the side wall 12 of the back plate 10; in this process, the periphery surface of the optical component 20 first squeezes the elastic buffer 40, so that the elastic buffer 40 is elastically deformed and compressed, and a certain space is released on the periphery of the optical component 20 by the elastic compression of the elastic buffer 40, so that the optical component 20 can expand safely along the released space, so as to avoid the optical component 20 from being arched, deformed or even damaged due to space compression, and ensure that the optical component 20 remains flat and intact, thereby ensuring the light output quality of the display device 1 and the display visual effect of the display device.

[0030] The material of the elastic buffer 40 can be determined according to actual needs, and the embodiment of the present application does not limit this. In some embodiments, the elastic buffer 40 can be a foam member or a rubber member; these materials have good elasticity, so that the elastic buffer 40 can be compressed and deformed to a large extent, thereby providing a relatively sufficient expansion space for the optical component 20.

[0031] The shape and structure of the bottom wall 11 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the bottom wall 11 may 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 inclined around the edge of the lower wall portion 111, and the inclined wall portion 112 and the lower wall portion 111 are inclined at an angle. The upper wall portion 113 is inclined 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 inclined at an angle. 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 and the lower wall portion 111 are relatively spaced, and the display panel 30 can be arranged on a side surface of the optical component 20 away from the upper wall portion 113. In some examples, the lower wall 111 and the upper wall 113 may be arranged in parallel; in other examples, the lower wall 111 and the upper wall 113 may be arranged obliquely. When the display device 1 further includes an elastic buffer 40 , the elastic buffer 40 may be arranged on the upper wall 113 .

[0032] The shape structure of the side wall 12 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the side wall 12 may include an outer wall portion 121 and a bent wall portion 122 connected in sequence. One end of the outer wall portion 121 is connected to the bottom wall 11, and the bent wall portion 122 is formed on the edge of one end of the outer 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 spaced to form a gap area. The bent wall portion 122 can be arranged around the display panel 30, and a matching 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 also includes an elastic buffer 40, the edge of the elastic buffer 40 can be embedded in the gap area between the bent wall portion 122 and the bottom wall 11.

[0033] In some embodiments, the display device 1 may further include a reflective sheet 50. The optical component 20 and the reflective sheet 50 are sequentially stacked on the bottom wall 11, and the reflective sheet 50 and the bottom wall 11 are arranged in close contact. In this way, the optical component 20 is specifically located on the side of the reflective sheet 50 away from the bottom wall 11. The reflective sheet 50 can reflect the light irradiated to the bottom wall 11, so that this part of the light is reflected to the optical component 20, and then passes through the optical component 20 and then emits forward, thereby improving the luminous efficiency and light utilization rate of the display device 1.

[0034] In some examples, the optical component 20 may have a main light-transmitting portion 21 and an edge light-transmitting portion 22 surrounding the main light-transmitting portion 21. Here, the positions of the main light-transmitting portion 21 and the reflective sheet 50 coincide, that is, the orthographic projection of the main light-transmitting portion 21 on the plane where the reflective sheet 50 is located coincides with the reflective sheet 50; while 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 relatively spaced, that is, the orthographic projection of the edge light-transmitting portion 22 on the plane where the reflective sheet 50 is located does not overlap with the reflective sheet 50. The elastic buffer 40 is disposed between the edge light-transmitting portion 22 and the side wall 12. When the optical component 20 expands due to heat, the edge light-transmitting portion 22 and the elastic buffer 40 contact and interact with each other.

[0035] Exemplarily, the display device 1 may include an adhesive layer 60 having an annular structure, and the edge light-transmitting portion 22 of the optical component 20 and the bottom wall 11 of the back plate 10 are bonded and fixed by the adhesive layer 60. In this way, a reliable bonding and fixing relationship can be formed between the edge light-transmitting portion 22 and the bottom wall 11, and the degree of thermal expansion of the optical component 20 can be reduced to a certain extent by using the adhesive force, and the optical component 20 can be prevented from arching when the optical component 20 is about to be deformed, thereby better ensuring the flatness of the optical component 20.

[0036] The material of the adhesive layer 60 can be determined according to actual needs, and various types of transparent optical adhesives can be used, which is not limited in the embodiments of the present application. Exemplarily, the adhesive layer 60 can be a reflective adhesive layer. In this way, the adhesive layer 60 has a better reflection effect on light; when the light passes through the edge light-transmitting portion 22 and irradiates the adhesive layer 60, the adhesive layer 60 can reflect this part of the light, so that this part of the light is reflected onto the optical component 20, and then passes through the optical component 20 and then emits forward, thereby improving the luminous efficiency and light utilization rate of the display device 1.

[0037] The number of elastic buffers 40 provided in the display device 1 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the display device 1 may 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 an enclosing barrier between the circumference 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 its 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, providing expansion space for the optical component 20, thereby avoiding the optical component 20 from arching, deforming, or even being damaged, and ensuring the structural safety of the optical component 20 and the backlight quality of the display device 1.

[0038] In some embodiments, the fixing member 70 may be disposed at the edge of the optical component 20. The material of the fixing member 70 may be determined according to actual needs, and various types of transparent optical adhesives may be used, which are not limited in the embodiments of the present application; in some embodiments, the fixing member 70 may be an adhesive tape, which is used to bond and fix the optical component 20 and the display panel 30. In this way, a reliable bonding and fixing relationship can be established between the display panel 30 and the optical component 20, thereby ensuring the structural reliability of the display device.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea.
