[0027] With the continuous development of science and technology, display technology is increasingly widely used in work, life, production and other fields. Magnetism is generated with the generation of electricity, so in display products, electromagnetic compatibility issues are inevitable. Commonly, the electromagnetic compatibility of display products is solved by sticking a shielding film on the display cable, but this method can only shield part of the electromagnetic, resulting in poor electromagnetic compatibility performance of the display product, poor display effect of the display product, and may cause damage to some components in the display product. Therefore, it is particularly important to improve the electromagnetic compatibility performance of display products, so that the display products are not affected by electromagnetic interference in the surrounding environment and can work normally, while also avoiding electromagnetic interference to other electronic products in the surrounding environment.

[0028] See also Figure 1 and Figure 2 An embodiment of the present application provides a display component 100, which includes: a shell 110, a display screen 120 and a shielding film 130, wherein the shell 110 has a receiving cavity 111; the display screen 120 is arranged in the receiving cavity 111; the shielding film 130 is arranged on a side of the display screen 120 away from the shell 110 and is carried by the shell 110, and the shielding film 130 is electrically connected to the shell 110 so as to enclose the display screen 120 in the receiving cavity 111.

[0029] In the embodiment of the present application, the shielding film 130 has a high electromagnetic shielding function. The shielding film 130 is electrically connected to the housing 110 so that the display screen 120 is enclosed in the receiving cavity 111. In other words, the shielding film 130 encloses the receiving cavity 111 to form a closed chamber with the receiving cavity 111. When the display screen 120 is arranged in the receiving cavity 111, the electromagnetic waves generated by the display screen 120 during operation will be enclosed in the receiving cavity 111 and cannot be emitted, which can prevent the display screen 120 from causing electromagnetic interference to the surrounding electronic devices. Similarly, the electromagnetic waves generated by the outside world will also be blocked by the shielding film 130 and the housing 110 to prevent the electromagnetic waves from entering the receiving cavity 111 and causing electromagnetic interference to the display screen 120, so that the display component 100 has better electromagnetic compatibility, and then the display screen 120 can be prevented from being damaged by electromagnetic interference, which is conducive to improving the display effect of the display screen 120 and extending the service life of the display component 100.

[0030] See also Figure 3 and Figure 4 In some embodiments, the shielding film 130 includes a substrate layer 131 , a conductive layer 132 , and a shielding layer 133 that are stacked together, and the substrate layer 131 is disposed closer to the display screen 120 than the shielding layer 133 .

[0031] It can be understood that along the arrangement direction of the display screen 120 and the shielding film 130 , the substrate layer 131 , the conductive layer 132 and the shielding layer 133 are sequentially arranged.

[0032] In this embodiment, the shielding layer 133 is based on the substrate layer 131, and the substrate layer 131 is used to provide support for the conductive layer 132 and the shielding layer 133. The conductive layer 132 enables the shielding film 130 to have good conductivity, so as to improve the electrical connection stability between the shielding film 130 and the housing 110. Further, the shielding layer 133 can effectively prevent the penetration of electromagnetic waves. The substrate layer 131, the conductive layer 132 and the shielding layer 133 cooperate with each other to realize the electrical connection between the shielding film 130 and the housing 110, and form the receiving cavity 111 into a closed chamber to prevent electromagnetic waves outside the receiving cavity 111 from entering the receiving cavity 111, and to prevent electromagnetic waves inside the receiving cavity 111 from emitting from the receiving cavity 111, thereby preventing the display screen 120 from being interfered by external electromagnetic waves, and preventing the display screen 120 from interfering with external electromagnetic waves, so that the display component 100 has good electromagnetic compatibility.

[0033] Optionally, the substrate layer 131 is a transparent plastic layer, and the substrate layer 131 may be, but is not limited to, a polyethylene terephthalate (PET) layer, a polycarbonate (PC) layer, and a polymethyl methacrylate (PMMA) layer.

[0034] Optionally, the conductive layer 132 may be, but is not limited to, an indium tin oxide (ITO) layer and an aluminum zinc oxide (AZO) layer.

[0035] Optionally, the shielding layer 133 may be, but is not limited to, a nickel layer, a silver layer, and a copper layer.

[0036] Optionally, the thickness D of the shielding film 130 satisfies the range: 0.25mm≤D≤0.6mm. Specifically, the value of the thickness D of the shielding film 130 can be, but is not limited to, 0.25mm, 0.26mm, 0.28mm, 0.3mm, 0.32mm, 0.34mm, 0.36mm, 0.4mm, 0.43mm, 0.46mm, 0.47mm, 0.48mm, 0.5mm, 0.51mm, 0.52mm, 0.54mm, 0.55mm, 0.56mm, 0.58mm, 0.59mm and 0.6mm, etc. The shielding film 130 has good electromagnetic compatibility.

[0037] In some embodiments, the thickness D1 of the shielding layer 133 satisfies the range: 10 nm ≤ D1 ≤ 50 nm.

[0038] Specifically, the thickness D1 of the shielding layer 133 may be, but is not limited to, 10nm, 12nm, 14nm, 15nm, 18nm, 20nm, 22nm, 24nm, 25nm, 27nm, 28nm, 30nm, 32nm, 34nm, 35nm, 37nm, 40nm, 42nm, 44nm, 46nm, 48nm and 50nm, etc.

[0039] In this embodiment, when the thickness D1 of the shielding layer 133 satisfies the range of 10nm≤D1≤50nm, the thickness of the shielding layer 133 is within a reasonable range, so that the shielding layer 133 has a better performance in preventing electromagnetic waves from penetrating, and then the shielding film 130 has a better electromagnetic compatibility performance. In addition, it can also avoid the display component 100 being too thick due to the excessive thickness of the shielding layer 133, which is conducive to realizing a light and thin design of the display component 100.

[0040] In some embodiments, the thickness D2 of the conductive layer 132 satisfies the range: 50 nm ≤ D2 ≤ 200 nm.

[0041] Specifically, the thickness D2 of the conductive layer 132 may be, but is not limited to, 50 nm, 52 nm, 56 nm, 66 nm, 75 nm, 88 nm, 100 nm, 110 nm, 125 nm, 130 nm, 145 nm, 150 nm, 165 nm, 170 nm, 175 nm, 180 nm, 185 nm, 190 nm, 195 nm and 200 nm, etc.

[0042] In this embodiment, when the thickness D2 of the conductive layer 132 satisfies the range of 50nm≤D2≤200nm, the thickness of the conductive layer 132 is within a reasonable range, so that the conductive layer 132 has a sufficiently good conductivity, and then the shielding film 130 can be well electrically connected to the housing 110 to improve the electromagnetic shielding performance of the closed receiving cavity 111, so that the shielding film 130 has good electromagnetic compatibility. In addition, it can also avoid the display component 100 being too thick due to the excessive thickness of the conductive layer 132, which is conducive to realizing the light and thin design of the display component 100.

[0043] In some embodiments, the substrate layer 131 is a transparent member, the conductive layer 132 is a transparent member, and the shielding layer 133 is a transparent member.

[0044] In this embodiment, the substrate layer 131, the conductive layer 132 and the shielding layer 133 are transparent parts, so that the conductive film is a transparent part. When the substrate layer 131, the conductive layer 132 and the shielding layer 133 are stacked in sequence on the surface of the display screen 120 away from the housing 110, the shielding film 130 can be prevented from blocking the display screen 120, which is beneficial to improving the display effect of the display component 100.

[0045] Optionally, the light transmittance α of the shielding film 130 is in the range of 82%≤α≤95%. Specifically, the light transmittance α of the shielding film 130 may be, but is not limited to, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94% and 95%. The shielding film 130 has a good light transmission effect.

[0046] See also Figure 5 In some embodiments, the display assembly 100 further includes a conductive member 140 , and the conductive member 140 is disposed between the housing 110 and the shielding film 130 , and is used to electrically connect the shielding film 130 to the housing 110 .

[0047] In this embodiment, the conductive member 140 has good conductivity, and is disposed between the housing 110 and the shielding film 130 to improve the conductivity between the shielding film 130 and the housing 110, so that the receiving cavity 111 is enclosed into a closed chamber and the shielding film 130 and the housing 110 have good electrical connection performance. Accordingly, when the display screen 120 is disposed in the receiving cavity 111, the electromagnetic waves generated by the display screen 120 during operation will be enclosed in the receiving cavity 111 and cannot be emitted, thereby preventing the display screen 120 from causing electromagnetic interference to surrounding electronic devices. Similarly, electromagnetic waves generated from the outside will also be blocked by the shielding film 130 and the outer shell 110 to prevent the electromagnetic waves from the outside from entering the receiving cavity 111 and causing electromagnetic interference to the display screen 120, so that the display component 100 has better electromagnetic compatibility performance, and then the display screen 120 can be prevented from being damaged due to electromagnetic interference, which is beneficial to improving the display effect of the display screen 120 and extending the service life of the display component 100.

[0048] Optionally, the conductive member 140 is electrically connected to the conductive layer 132 of the shielding film 130 .

[0049] Optionally, in some embodiments, the conductive member 140 is a conductive foam, and the material of the conductive foam is relatively soft. When the conductive foam is disposed between the shell 110 and the shielding film 130, the material of the shell 110 and the shielding film 130 is relatively hard, and the conductive foam can better support the shell 110 and the shielding film 130 to enhance the point connection performance between the shell 110 and the shielding film 130.

[0050] In some embodiments, the display assembly 100 further includes an adhesive member 150 , which is disposed in the same layer as the conductive member 140 and spaced apart from each other. The adhesive member 150 is used to connect the housing 110 and the shielding film 130 .

[0051] In this embodiment, the adhesive member 150 and the conductive member 140 are disposed in the same layer, which is conducive to saving space in thickness of the display assembly 100, and then is conducive to realizing a miniaturized design of the display assembly 100. In addition, the adhesive is used to connect the housing 110 with the shielding film 130, which is conducive to enhancing the bonding performance between the housing 110 and the shielding film 130, and preventing the shielding film 130 from falling off from the housing 110 or being misaligned with the housing 110, thereby reducing the electromagnetic compatibility performance of the display assembly 100.

[0052] Optionally, the adhesive member 150 is a double-sided tape.

[0053] In some embodiments, the display assembly 100 further includes a touch screen 160 , and the touch screen 160 is disposed on a side of the shielding film 130 facing away from the display screen 120 .

[0054] It can be understood that in the display assembly 100 , the display screen 120 , the shielding film 130 , and the touch screen 160 are arranged in sequence.

[0055] In this embodiment, the display component 100 further includes a touch screen 160, and the touch screen 160 can receive touch information, so that the operator can touch the display component 100, so that the display component 100 has touch performance. Further, the touch screen 160 is arranged on the side of the shielding film 130 away from the display screen 120. In other words, the touch screen 160 and the display screen 120 are arranged on opposite sides of the shielding film 130. On the one hand, the shielding film 130 can shield the electromagnetic interference of the touch screen 160 on the display screen 120 to avoid interference with the display effect of the display screen 120; on the other hand, the shielding film 130 can shield the electromagnetic interference of the display screen 120 on the touch screen 160 to avoid damage to the touch performance of the touch screen 160. In this embodiment, the display component 100 has good electromagnetic compatibility, so that the display component 100 has good display performance and touch performance.

[0056] In some embodiments, the display component 100 also includes a first connecting layer 170 and a second connecting layer 180, wherein the first connecting layer 170 is disposed between the display screen 120 and the shielding film 130 to connect the display screen 120 and the shielding film 130; the second connecting layer 180 is disposed between the shielding film 130 and the touch screen 160 to connect the shielding film 130 and the touch screen 160.

[0057] It can be understood that in the display assembly 100 , the display screen 120 , the first connection layer 170 , the shielding film 130 , the second connection layer 180 and the touch screen 160 are stacked in sequence.

[0058] In this embodiment, the first connection layer 170 is used to connect the display screen 120 and the shielding film 130, so as to prevent the display screen 120 and the shielding film 130 from sliding relative to each other during use, which is beneficial to improving the structural stability of the display screen 120 and the shielding film 130 disposed on the display assembly 100. In addition, the second connection layer 180 is used to connect the shielding film 130 and the touch screen 160, so as to prevent the shielding film 130 and the touch screen 160 from sliding relative to each other during use, which is beneficial to improving the structural stability of the shielding film 130 and the touch screen 160 disposed on the display assembly 100. Furthermore, the relative positions of the display screen 120, the shielding film 130 and the touch screen 160 in the display component 100 are fixed, so that the relative positions of the shielding film 130 and the outer shell 110 are stable, which is beneficial to maintaining the stability of the closed chamber formed by the outer shell 110 and the shielding film 130, so that the shielding film 130 can shield the electromagnetic interference between the display screen 120 and the touch screen 160, and thus the display component 100 has better electromagnetic compatibility, display performance and touch performance.

[0059] Optionally, the first connection layer 170 is an optical adhesive layer, and the second connection layer 180 is an optical adhesive layer.

[0060] In some embodiments, the display assembly 100 further includes a third connection layer 190 , which is disposed between the display screen 120 and the housing 110 and is used to connect the display screen 120 to the housing 110 .

[0061] In this embodiment, the third connection layer 190 is disposed between the display screen 120 and the housing 110. On the one hand, the third connection layer 190 strengthens the connection performance between the display screen 120 and the housing 110, and then strengthens the structural stability of the display screen 120 disposed on the display assembly 100. In addition, the display screen 120 and the housing 110 are connected through the third connection layer 190. Compared with the solution in which the display screen 120 and the housing 110 are directly abutted, the third connection layer 190 provided in the present application can be used as a buffer layer to reduce the risk of the display screen 120 and the housing 110 colliding and breaking, which is conducive to extending the service life of the display assembly 100.

[0062] See also Figure 6 An embodiment of the present application further provides a display device 200, and the display device 200 includes: a display component 100 provided in the present application and a processor 210, wherein the processor 210 is electrically connected to the display component 100 and is used to control the display screen 120 to display.

In this embodiment, the processor 210 is electrically connected to the display component 100, specifically, the processor 210 is electrically connected to the display screen 120 to control the display screen 120 to display.
