The force borne by the hemisphere block is converted into the air pressure of compressed air, the hemisphere block is designed to not affect splicing of the first display screen and the second display screen at different angles, and meanwhile before the first display screen makes contact with the second display screen, two rubber strips on the back face of the first display screen are matched with two rubber strips on the back face of the second display screen; and the buffering protection effect is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a splicable liquid crystal display screen. Background Art

[0002] In the market, there is an LCD display solution called Video Wall. Video Wall can seamlessly splice multiple LCD screens together to form a huge display. This technology is often used in shopping malls, control rooms, conference rooms, studios and other occasions where large-size images are required. Usually, Video Wall uses special brackets and frames to connect multiple LCD screens together. There are usually very narrow borders between these screens so that seamless splicing can be achieved when splicing. At the same time, equipped with professional splicing controllers and software, the contents of multiple screens can be displayed synchronously and visually present a seamless and continuous image.

[0003] The prior art provides a splicable liquid crystal display screen (Announcement No.: CN212005037U), which includes a sub-screen, a spliced ​​screen, and a fixed bracket fixedly connected to the sub-screen and the spliced ​​screen respectively. A universal wheel is arranged at the bottom of the fixed bracket of the spliced ​​screen, and a support plate is fixedly connected to the bottom of the sub-screen. A rotating rod connected to the sub-screen for rotation is penetrated in the support plate. The rotating rod and the adjacent fixed bracket are fixedly connected with a gear, and a spring is fixedly connected to the bottom of the gear on the rotating rod. The utility model drives the rotation of the rotating wheel and the rotating rod by rotating the handle, and realizes the movement of the toothed plate on the spliced ​​screen through the meshing transmission of the gear and the toothed plate, realizes the mobile docking of the spliced ​​screen and the sub-screen, and makes it easier to realize the angle splicing of the spliced ​​screen and the sub-screen.

[0004] But the device still has the following defects:

[0005] When the device is in use, the device uses two display screens to be close together for splicing. During the close process, a collision will occur between the two display screens, which is easy to cause damage to the display screens. Therefore, we need to propose a splicable LCD display screen.
