The display panel 200 can be an LCD display panel 200 (liquid crystal display panel 200), or an OLED display panel 200 (organic light emitting diode display panel 200). In this embodiment, the OLED display panel 200 is preferably used. The OLED display panel 200 has high contrast, light weight, and high brightness. The display panel 200 has the advantages of being thin, having a wide viewing angle and having a fast response speed, and can be applied to high-end mobile phones, televisions or other display fields. The cross-section of the display panel 200 can be rectangular, circular, elliptical or other common shapes. Preferably, in this embodiment, the cross-section of the display panel 200 is rectangular; the electromagnetic shielding component 300 can be shielding glass, a transparent electromagnetic shielding film or other transparent electromagnetic protection material.

The bonding part 401 is connected, or the second bonding part 402 is integrally formed with the first bonding part 401, and the second bonding part covers the side of the electromagnetic shielding part 300 and the display panel 200, and the side is all the sides except the top and bottom surfaces, and is all the surfaces connecting the top and bottom surfaces; the second bonding part can cover all the side surfaces, or can cover part of the side surfaces; at the same time, if the cross-sectional shape of the electromagnetic shielding part 300 is different from the cross-sectional shape of the display panel, the cross-sectional part of the electromagnetic shielding part in contact with the display panel and the part of the cross-sectional part that is not in contact with each other is also the side surface, that is, the first bonding part can also cover the part of the cross-sectional part of the electromagnetic shielding part in contact with the display panel that is not overlapped. The electromagnetic shielding effect is further improved by the second bonding part 402. The elastic part 500 is made of elastic material, and the elastic part 500 can be a spring, a rubber block or other elastic material.

[0046] The display device provided in this embodiment uses the elastic member 500 to make the first fitting part 401 generate pressure on the inner wall of the shielding cavity 101, so that the first fitting part 401 is pressed against the inner wall of the shielding cavity 101 (to achieve seamless conductive connection), avoiding poor contact between the first fitting part 401 and the inner wall of the shielding cavity 101, and avoiding electromagnetic leakage caused by a gap between the first fitting part 401 and the inner wall of the shielding cavity 101. The connection stability between the first fitting part 401 and the inner wall of the shielding cavity 101 is improved, so that the first fitting part 401 forms a good overlap effect with the bottom of the receiving groove, thereby improving the reliability of electromagnetic shielding.

[0047] like Figure 1 As shown, in the display device provided by this embodiment, the orthographic projection of the first laminating portion 401 on the display panel 200 does not overlap with the display area, that is, the first laminating portion 401 is located directly below the frame of the display panel 200, and the first laminating portion 401 does not cover the display area of ​​the display panel 200, thereby preventing the first laminating portion 401 from covering the display area.

[0048] In the display device provided in this embodiment, the conductive foil 400 includes one or more of embossed tinned copper foil, silver foil, and composite conductive materials.

After the conductive foam 601 is subjected to the pressure provided by the elastic member 500, it is compressed and deformed, so that the first fitting portion 401 is tightly connected to the inner wall of the shielding cavity 101 through the conductive foam 601, so that the electromagnetic shielding layer and the shell form a low-impedance reliable electrical connection, thereby improving the electromagnetic shielding capability.

[0051] like Figure 2 As shown, the display device provided in this embodiment also includes a first conductive seal 602. The first conductive seal 602 can be a conductive sealing gasket, or a metal wire mesh. The conductive foam 601 forms a sealed connection with the bottom of the receiving groove through the first conductive seal 602 to avoid electromagnetic leakage and reduce the electromagnetic radiation of the display device itself.

[0052] like Figure 1 and Figure 2 As shown, the display device provided in this embodiment further includes a shock absorbing member 604, which is a rubber pad or a shock absorbing pad made of other elastic materials. The shock absorbing member 604 is arranged between the cover plate and the display panel 200, and the shock absorbing pad can be bonded to the substrate surface of the display panel 200 by gluing. On the one hand, the shock absorbing pad can limit the display panel 200, and on the other hand, the shock absorbing pad can also buffer the display panel 200 to prevent the display panel 200 from directly colliding with the inner wall of the receiving groove due to external impact. The initial elastic force of the elastic member 500 will also cause the display panel 200 to generate pressure on the shock absorbing member 604, increase the friction between the shock absorbing member 604 and the upper surface of the display panel 200, thereby increasing the resistance to the movement of the display panel 200, and thus reducing the movement of the display panel 200.

[0053] like Figure 1 As shown, the display device provided by this embodiment, the conductive shell 100 includes a conductive seat 103 and a conductive cover plate 104, the conductive seat 103 is provided with a receiving groove, the opening 102 is provided at the bottom of the conductive seat 103, the opening 102 is located directly below the receiving groove, and the opening 102 is connected to the receiving groove, the cross-sectional area of ​​the receiving groove is larger than the cross-sectional area of ​​the electromagnetic shielding component 300, the conductive cover plate 104 is fixedly connected to the top of the conductive shell 100, and the fixing method can be bolts, bonding or other common fixing methods. After the conductive cover plate 104 is fixedly connected to the conductive shell 100, the conductive cover plate 104 is covered on the receiving groove, and the conductive cover plate 104, the receiving groove and the electromagnetic shielding component 300 enclose a shielding cavity 101, and the display panel 200 is located in the shielding cavity 101.

[0054] like Figure 1 and Figure 2 As shown, the display device provided in this embodiment also includes a second conductive seal 603, which is located in the connecting gap between the conductive shell 100 and the conductive cover plate 104, and is used to fill the gap to avoid electromagnetic leakage. The second conductive seal 603 can be a metal wire mesh or a conductive sealing gasket. The conductive cover plate 104 is connected to the conductive shell 100 through the second conductive seal 603, further improving the sealing of the shielding cavity 101.

[0055] The display device provided in this embodiment has an installation process as follows:

[0056] First, the electromagnetic shielding component 300 is bonded to the display panel of the display panel 200 by optical glue, and then the first bonding portion 401 is bonded to the surface of the side of the electromagnetic shielding component 300 facing away from the display panel 200 by bonding tape, and then the second bonding portion 402 is enclosed to form a hollow cavity, and the hollow cavity is sleeved outside the electromagnetic shielding component 300 and the display panel 200, and the inner wall of the hollow cavity is evenly bonded to the side of the electromagnetic shielding component 300 and the outer side of the display panel 200, and the inner wall of the second bonding portion 402 is evenly bonded to the side of the electromagnetic shielding component 300 and the display panel 200 by bonding tape, so that the edge wrapping of the transparent shielding component and the display panel 200 by the conductive foil 400 is completed. The seal 602 is fitted with the bottom of the accommodating groove, the conductive foam 601 is fitted with the first conductive seal 602, and then the first fitting part 401 is placed on the conductive foam 601 with the side facing away from the electromagnetic shielding part 300, and then the elastic part 500 is inserted into the gap between the second fitting part 402 and the inner wall of the accommodating groove, so that the two ends of the elastic part 500 are abutted against the second fitting part 402, and the middle part of the elastic part 500 is abutted against the inner wall of the accommodating groove, and then the shock absorbing part 604 is pasted on the substrate surface of the display panel 200, the second conductive seal 603 is placed on the conductive shell 100, and then the conductive cover is placed on the second conductive seal 603, and then the conductive cover plate 104 is fixedly connected to the conductive shell 100 by bolts.
