MULTI-DISPLAY SYSTEM AND VIDEO DISPLAY DEVICE Russian patent published in 2020 - IPC G09F9/30 G09F9/40 

FIELD: image forming devices.

SUBSTANCE: invention relates to a multi-display system for displaying video information on a large screen by arranging a plurality of video display devices in a vertical direction and a transverse direction and a video display device. Disclosed invention consists in developing a technology which enables easy access to both the display surface and the rear surface of the video display device, and also improves the quality of video information. Each of the LED display tiles is imparted movement in the transverse direction by a rotation operation to adjust the crosswise position of the handle. Each of the light-emitting diode display tiles is imparted movement in the vertical direction by a rotation operation adjusting the vertical position of the handle. In the state where the mounting pin is inserted into the hole portion, the surface of the adjustment of the level difference of the element on the side of the setting pin sticks to the contact portion under the magnetic force of the magnet, whereby each of the LED display mats is attached to the supporting structure.

EFFECT: enabling easy access to both the display surface side and the rear side of the video display device rear side and improved quality of video information due to accurate adjustment of gaps in the transverse direction and vertical direction and the difference of levels in the direction back and forth on the display surfaces between the video display device and other video display devices adjacent thereto and fixing them in that state.
