[0002] LCD liquid crystal display, the structure of LCD is to place a liquid crystal box between two parallel glass substrates, TFT is set on the lower substrate glass, and color filter is set on the upper substrate glass. The rotation direction of the liquid crystal molecules is controlled by changing the signal and voltage on the TFT, thereby controlling whether the polarized light of each pixel is emitted or not to achieve the display purpose. LCD has replaced CRT and become the mainstream. The price has also dropped a lot and has been fully popularized.

[0003] After searching, it was found that a Chinese patent with publication number CN219841323U discloses an LCD screen that is easy to install. The technical point is: it solves the problem that the position of the screen cannot be changed at will after installation and fixation, and it needs to be installed with the help of external tools. The installation operation will be relatively cumbersome, which greatly increases the difficulty of installation.
