[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a display device 100 is provided, including a display frame 1, a display screen 2, and a light-shielding structure 3; the display frame 1 is connected to the front end of the holographic device's housing 200; the housing 200 is equipped with a backlight assembly, which includes a top backlight panel 201, a bottom backlight panel 202, and two side backlight panels 203 arranged in a ring; the display screen 2 is connected to the display frame; the light-shielding structure 3 is connected to the display frame 1 or the housing 200. The front end of the light-shielding structure 3 abuts against the outer edge of the display screen 2, and the rear end of the light-shielding structure 3 extends into the interior of the backlight assembly. The light-shielding structure 3 includes a top light-shielding strip 31, a bottom light-shielding strip 32, and two side light-shielding strips 33 arranged in a ring shape. The top light-shielding strip 31 is arranged to cross the front end of the top backlight panel 201. The bottom light-shielding strip 32 is arranged to cross the front end of the bottom backlight panel 202. The two side light-shielding strips 33 are arranged to cross the front ends of the two side backlight panels 203 respectively.

[0041] The front end of the light-shielding structure 3 abuts against the outer edge of the display screen 2. The rear end of the top light-shielding strip 31 is located inside the top backlight panel 201 and intersects with the front end of the top backlight panel 201. It can block the light from the top backlight panel 201, preventing the light from the front end of the top backlight panel 201 near the display device 100 from being projected onto the display device 100, thus avoiding light from causing flooding on the top of the display device 100 and affecting the three-dimensional display effect of the holographic device. The rear end of the bottom light-shielding strip 32 is located inside the bottom backlight panel 202 and intersects with the front end of the bottom backlight panel 202. It can block the light from the bottom backlight panel 202, preventing the light from flooding on the bottom backlight panel 202. The backlight panel 202 near the front of the display device 100 projects light onto the display device 100, preventing the bottom of the display device 100 from glare and thus avoiding affecting the three-dimensional display effect of the holographic device. Two side light-shielding strips 33 are located inside the two side backlight panels 203 and are respectively intersected with the front of the two side backlight panels 203. These strips block the light from the two side backlight panels 203, preventing light from the front of the display device 100 from being projected onto the display device 100, thus preventing glare on the two sides of the display device 100 and thus avoiding affecting the three-dimensional display effect of the holographic device. The light-shielding structure 3 blocks the light from the back panel assembly near the front of the display device 100, preventing light from being projected onto the display device 100 and preventing glare at the edges of the display device 100, ensuring the three-dimensional display effect of the holographic device.

[0042] In some other related technologies, the display screen 2 of the display device 100 can also be connected to the housing 200 by double-sided adhesive. This can easily lead to gaps between the display screen 2 and the housing 200, causing light to leak out from the gaps, resulting in light leakage, reduced 3D effect, and negatively impacting user experience. In this embodiment, the front end of the light-shielding structure 3 abuts against the outer edge of the display screen 2, and the rear end extends inside the backlight assembly. The top light-shielding strip 31 is intersected with the front end of the top backlight panel 201; the bottom light-shielding strip 32 is intersected with the front end of the bottom backlight panel 202; and the two side light-shielding strips 33 are intersected with the front ends of the two side backlight panels 203, respectively. These measures block the gaps between the display screen 2 and the housing 200, preventing light leakage, ensuring 3D effect, and improving user experience.

[0043] In one embodiment, the top light-shielding strip 31, one side light-shielding strip 33, the bottom light-shielding strip 32, and another side light-shielding strip 33 are sequentially connected to form a light-shielding ring.

[0044] The light-shielding ring can block the light from the backlight assembly in the circumferential direction, ensuring that there are no light leakage gaps in the light-shielding structure 3 in the circumferential direction. This prevents the light from the top light-shielding strip 31, the bottom light-shielding strip 32, and the two side light-shielding strips 33 near the front of the display device 100 from being projected onto the display device 100, thus avoiding the light causing the edges of the display device 100 to glare and preventing the three-dimensional display effect of the holographic device.

[0045] As an alternative implementation, the top light-shielding strip 31, one of the side light-shielding strips 33, the bottom light-shielding strip 32, and the other side light-shielding strip 33 can be formed separately, which can facilitate individual connection and disassembly.

[0046] In one embodiment, the light-shielding structure 3 further includes a connecting portion 34 protruding outwards. At least one connecting portion 34 is provided on the top light-shielding strip 31, the bottom light-shielding strip 32, and the two side light-shielding strips 33. The connecting portion 34 is connected to the display frame or the cabin 200.

[0047] The connecting portion 34, which protrudes outward, facilitates the connection of the top light-shielding strip 31, the bottom light-shielding strip 32, and the two side light-shielding strips 33 to the corresponding positions of the display frame, or facilitates the connection of the top light-shielding strip 31, the bottom light-shielding strip 32, and the two side light-shielding strips 33 to the corresponding positions of the cabin 200.

[0048] In a specific implementation, the connecting portion 34, which protrudes outward, can be sheet-like, taking up little space and facilitating connection.

[0049] In one embodiment, the top light-shielding strip 31 is arranged parallel to the top backlight panel 201, the bottom light-shielding strip 32 is arranged parallel to the bottom backlight panel 202, and the side light-shielding strip 33 is arranged parallel to the side backlight panel 203.

[0050] The parallel arrangement facilitates installation and disassembly, does not take up too much space inside the cabin 200, enhances aesthetics, and does not affect the reflection of other light inside the cabin 200.

[0051] As an alternative implementation, the top light-shielding strip 31 and the top backlight panel 201 may also have a small included angle.

[0052] In one embodiment, the top light-shielding strip 31, the bottom light-shielding strip 32, and the two side light-shielding strips 33 are all arranged perpendicularly to the corresponding connecting portion 34.

[0053] The vertically positioned connecting part 34 facilitates connection and occupies less space.

[0054] In one embodiment, the connecting part 34 is provided with a first connecting hole 35, and the display frame or the cabin 200 is provided with a corresponding second connecting hole. The first connecting hole 35 and the second connecting hole are detachably connected by fasteners.

[0055] The first connecting hole 35 and the second connecting hole are detachably connected by fasteners, which facilitates the detachable connection of the connecting part 34 and the display frame or housing 200, and facilitates the maintenance of the display device 100.

[0056] In a specific implementation, the fastener includes a screw and a nut, with the screw passing through the first connecting hole 35 and the second connecting hole and being detachably connected to the nut.

[0057] In one embodiment, the connecting portion 34 is provided with a clearance hole 36, which is used to avoid the connecting structure on the display frame 1.

[0058] The clearance hole 36 avoids the connection structure on the display frame 1, which facilitates the connection or disassembly between the display device 100 and the housing 200, or facilitates the connection or disassembly between the various components of the display device 100.

[0059] In one embodiment, the connecting portion 34 is correspondingly disposed at the front end of the top light-shielding strip 31, the bottom light-shielding strip 32, and the two side light-shielding strips 33.

[0060] The connecting part 34 is located at the front end, which can ensure that the top light-shielding strip 31 has sufficient length to block the top backlight panel 201; the bottom light-shielding strip 32 has sufficient length to block the bottom backlight panel 202; and the rear ends of the two side light-shielding strips 33 have sufficient length to block the two side backlight panels 203 respectively.
