[0002] A liquid crystal display (LCD) is an active-matrix liquid crystal display driven by thin-film transistors. It primarily uses electrical current to stimulate liquid crystal molecules to create dots, lines, and surfaces, which, in conjunction with backlighting, form the image. LCD screens offer superior brightness, wider viewing angles, and better color reproduction compared to traditional LCD panels. LCD screens are commonly used in airports, shopping malls, hotels, high-speed rail, subways, cinemas, exhibitions, and office buildings. Currently, LCD screens are frequently used in video conferencing. The demand for LCD screens in meeting scenarios is gradually increasing, but their orientation and positioning capabilities often become technical bottlenecks.

The support column 7 is provided with multiple slots corresponding to the arc-shaped locking rod 6, which are used to fix the mounting block 5. A torsion spring is sleeved on the pin 9. The two ends of the torsion spring are respectively abutted by the arc-shaped locking rod 6 and the mounting block 5, which provide a certain torsional support for the arc-shaped locking rod 6. A first limiting block 21 is fixedly connected to the end of the support column 7 near the mounting block 5, and a second limiting block 22 is fixedly connected to the end of the support column 7 away from the mounting block 5, which limits the position of the support column 7.

[0023] In this embodiment, the horizontal adjustment structure includes a mounting plate 10 and a rotating rod 11. The mounting plate 10 has a through-hole corresponding to the support column 7. The rotating rod 11 is rotatably inserted into the through-hole. A slider 23 is fixedly connected to the top of the through-hole to limit the position of the support column 7.
