[0044] The detachable connection between the pressure plate 4 and the display frame 1 can fix the included angle of the display screen 3, preventing the display screen 3 from warping and further enhancing the installation and fixing effect of the display screen 3. Furthermore, the detachable connection between the pressure plate 4 and the two adjacent frame edges of the display frame 1 facilitates the disassembly of the display screen 3, reducing the overall disassembly and assembly difficulty of the display device 100, thereby improving the efficiency of disassembly and assembly of the display device 100 and facilitating the disassembly and assembly of the display device 100. In addition, by fixing the display screen 3 with the fixed pressure frame 2, the connection stability of the display device 100 can be guaranteed, avoiding connection failure over time and preventing the display screen 3 from falling off due to connection failure.

[0045] The shape of the display frame 1 matches the shape of the display screen 3 and the cabin 200.

[0046] In one embodiment, the pressure plate 4 has a first connecting hole at both ends, and the display frame 1 has a second connecting hole at the position of the two adjacent frame sides near the included angle. The first connecting hole and the second connecting hole are detachably connected by a first fastener.

[0047] The first connecting hole and the second connecting hole are detachably connected by the first fastener, which facilitates the detachable connection of the pressure plate 4 and the display frame 1, so as to facilitate the removal of the pressure plate 4 for maintenance of the display screen 3.

[0048] In a specific implementation, the first fastener includes a screw and a nut, with the screw passing through a first connecting hole and a second connecting hole and being detachably connected to the nut.

[0049] In one embodiment, the display device 100 further includes a first elastic pad sandwiched between the pressure plate 4 and the display frame 1.

[0050] By setting the first elastic pad, a buffer can be provided between the pressure plate 4 and the display frame 1, protecting the pressure plate 4 and the display frame 1 and preventing damage caused by excessive force.

[0051] In a specific implementation, the first elastic pad is provided with a through hole, and the first fastener can pass through the first elastic pad when connecting the first connecting hole and the second connecting hole, which can both fix the first elastic pad and facilitate the connection of the first fastener.

[0052] In one embodiment, the first elastic pad is a sheet-like structure that matches the shape of the pressure plate 4 and is sandwiched between the pressure plate 4 and the display screen 3.

[0053] The pressure plate 4 and the display screen 3 are also buffered and protected by a first elastic pad to prevent damage to the display screen 3.

[0054] In a further embodiment, the pressure plate 4 and the first elastic pad are connected to each corner of the display frame 1.

[0055] In one embodiment, the fixed frame 2 includes an annular frame 21 and a connecting part 22; the shape of the annular frame 21 matches the shape of the display frame 1, and the display screen 3 is fixedly clamped between the annular frame 21 and the display frame 1; the connecting part 22 protrudes from the outer periphery of the annular frame 21, and at least one connecting part 22 is provided on the frame side of each annular frame 21, and the connecting part 22 is detachably connected to the display frame 1.

[0056] The annular frame 21 cooperates with the display frame 1 to clamp and fix the outer edge of the display screen 3, and fixes the display screen 3 in all directions in the circumferential direction. The connecting part 22 is used to detachably connect the annular frame 21 and the display frame 1, which facilitates the installation of the display screen 3 and the disassembly and maintenance of the display screen 3.

[0057] In one embodiment, the connecting part 22 is provided with a third connecting hole, and the display frame 1 is provided with a corresponding fourth connecting hole. The third connecting hole and the fourth connecting hole are detachably connected by a second fastener.

[0058] The third and fourth connecting holes are detachably connected by a second fastener, which facilitates the detachable connection of the ring frame 21 to the display frame 1, so as to facilitate the disassembly of the ring frame 21 for maintenance of the display screen 3.

[0059] In a specific implementation, the second fastener includes a screw and a nut, with the screw passing through the first connecting hole and the second connecting hole and being detachably connected to the nut.

[0060] In one embodiment, the display device 100 further includes a second elastic pad sandwiched between the connecting portion 22 and the display frame 1.

[0061] By setting the second elastic pad, a buffer can be provided between the display frame 1 and the connecting part 22, protecting the connecting part 22 and the display frame 1 and preventing damage caused by excessive force.

[0062] In one embodiment, the display device 100 further includes a light-shielding structure 5 connected to the display frame 1 or the housing 200, and the fixing frame 2 is disposed between the light-shielding structure 5 and the display frame 1; the housing 200 is provided with a backlight assembly inside, the backlight assembly including a top backlight plate, a bottom backlight plate and two side backlight plates arranged in a ring; the rear end of the light-shielding structure 5 extends into the backlight assembly, the light-shielding structure 5 including a top light-shielding strip, a bottom light-shielding strip and two side light-shielding strips arranged in a ring; the top light-shielding strip is arranged to cross the front end of the top backlight plate; the bottom light-shielding strip is arranged to cross the front end of the bottom backlight plate, and the two side light-shielding strips are respectively arranged to cross the front end of the two side backlight plates.

[0063] The front end of the light-shielding structure 5 abuts against the outer edge of the display screen 3. The rear end of the top light-shielding strip is located inside the top backlight panel and intersects with the front end of the top backlight panel, which can block the light from the top backlight panel and prevent the light from the front end of the top backlight panel near the display device 100 from being projected onto the display device 100, thus avoiding the light causing the top of the display device 100 to flood and affecting the three-dimensional display effect of the holographic device. The rear end of the bottom light-shielding strip is located inside the bottom backlight panel and intersects with the front end of the bottom backlight panel, which can block the light from the bottom backlight panel and prevent the bottom backlight from flooding. Light from the front of the backlight panel near the display device 100 is projected 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 are located inside the two side backlight panels and are intersected with the front of the two side backlight panels, blocking the light from the two side backlight panels to prevent 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 5 blocks the light from the front of the backlight panel near 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.

[0064] In some other related technologies, the display screen 3 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 3 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 5 abuts against the outer edge of the display screen 3, and the rear end extends inside the backlight assembly. The top light-shielding strip intersects with the front end of the top backlight panel; the bottom light-shielding strip intersects with the front end of the bottom backlight panel; and the two side light-shielding strips intersect with the front ends of the two side backlight panels respectively. This blocks the gaps between the display screen 3 and the housing 200, preventing light leakage, ensuring 3D effect, and improving user experience.

[0065] In one embodiment, the top light-shielding strip, one of the side light-shielding strips, the bottom light-shielding strip, and another side light-shielding strip are sequentially connected to form a light-shielding ring.

[0066] 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 5 in the circumferential direction. This prevents the light from the top light-shielding strip, bottom light-shielding strip and two side light-shielding strips from being projected onto the display device 100 near the front end of the display device 100, and avoids the light causing the edges of the display device 100 to glare, thus avoiding the three-dimensional display effect of the holographic device.

[0067] In a specific implementation, the light-shielding ring can be fitted around the outer periphery of the annular frame 21 to improve the connection stability and convenience between the two.

[0068] As an alternative implementation, the top light-shielding strip, one of the side light-shielding strips, the bottom light-shielding strip, and the other side light-shielding strip can be formed separately, which can facilitate individual connection and disassembly.

[0069] In one embodiment, the light-shielding structure 5 further includes a connecting ear protruding outwards. At least one connecting ear is provided on the top light-shielding strip, the bottom light-shielding strip, and the two side light-shielding strips. The connecting ear is connected to the display frame 1 or the cabin 200.

[0070] The connecting ears protruding outwards facilitate the connection of the top light-shielding strip, the bottom light-shielding strip, and the two side light-shielding strips to the corresponding positions of the display frame 1, or facilitate the connection of the top light-shielding strip, the bottom light-shielding strip, and the two side light-shielding strips to the corresponding positions of the cabin 200.

[0071] In a specific implementation, the connecting ear protruding outwards can be sheet-like, taking up little space and facilitating connection. The connecting ear and the connecting part 22 are offset from each other.

[0072] In one embodiment, the top light-shielding strip is arranged parallel to the top backlight panel, the bottom light-shielding strip is arranged parallel to the bottom backlight panel, and the side light-shielding strip is arranged parallel to the side backlight panel.

[0073] 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.

[0074] As an alternative implementation, the top light-shielding strip and the top backlight panel may also have a small included angle.

[0075] In one embodiment, the top light-shielding strip, the bottom light-shielding strip, and the two side light-shielding strips are all arranged perpendicularly to the corresponding connecting ears.

[0076] The vertically positioned connectors facilitate connection and take up less space.

[0077] In one embodiment, the connecting ear is provided with a fifth connecting hole, and the display frame 1 or the cabin 200 is provided with a corresponding sixth connecting hole. The fifth connecting hole and the sixth connecting hole are detachably connected by a third fastener.

[0078] The fifth and sixth connection holes are detachably connected by the third fastener, which facilitates the detachable connection of the connection ear to the display frame 1 or the housing 200, and facilitates the maintenance of the display device 100.

[0079] In a specific embodiment, the third fastener includes a screw and a nut, with the screw passing through the fifth and sixth connecting holes and detachably connected to the nut. A third elastic pad is provided between the connecting ear and the display frame 1, or between the connecting ear and the housing 200.

[0080] In one embodiment, the connecting ear is provided with a clearance hole, which is used to avoid the connecting structure on the display frame 1.

[0081] The clearance hole avoids the connecting structure on the display frame 1, which facilitates the connection or disassembly between the display device 100 and the housing 200, or the connection or disassembly between the various components of the display device 100. Preferably, the clearance hole is used to avoid the connecting part 22.

[0082] In one embodiment, the connecting ear is disposed at the front end of the top light-shielding strip, the bottom light-shielding strip, and the two side light-shielding strips.

[0083] The connecting ears are located at the front end, ensuring that the top light-shielding strip has sufficient length to block the top backlight panel; the bottom light-shielding strip has sufficient length to block the bottom backlight panel; and the rear ends of the two side light-shielding strips have sufficient length to block the two side backlight panels respectively.

[0084] In one embodiment, the light-shielding structure 5 is made of acrylic material.

[0085] The material cost is relatively low and it is easy to mold.

[0086] According to an embodiment of the present invention, another aspect provides a holographic device, including the aforementioned display device 100.
