Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a wall-embedded LED display screen for a conference room. Background Art

[0002] In conference rooms, LED displays are usually embedded in the wall to facilitate participants to view and share information. Traditional embedded displays are cumbersome to install and are prone to falling off or falling.

[0003] A Chinese patent discloses an embedded conference LCD screen (authorization announcement number CN214796590U). This patent technology facilitates the installation and removal of the LCD screen through the rotating function of the rotating plate and the slide structure on the back of the rotating plate. The clamping plate structure allows the LCD screen to be fixed on the rotating plate, and the bottom of the LCD screen is fixed by fixing the position of the rotating plate. The top of the LCD screen is fixed by the fixed clamp and movable clamp structure under the connecting frame, and the stability of the LCD screen installation is increased by double fixation from top to bottom; however, it has certain disadvantages: it mainly fixes the screen by the elastic force of the spring and the sliding spring, so the stability is not enough. After the installation of the screen is completed, the rotating plate and the movable clamp are both attached to the display surface of the screen, which causes occlusion and affects the viewing effect.
