Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a door-type sliding matrix screen. Background Art

[0002] With the continuous advancement of science and technology and the improvement of people's living standards, the demand for display technology is also increasing. Although traditional fixed display screens can meet basic display needs, they are unable to cope with the need to display larger areas and higher resolution dynamic images in some special occasions, such as exhibitions and large-scale events. In order to solve this problem, matrix display technology has developed rapidly in recent years. Matrix display technology combines multiple independent display units into a whole to achieve high-resolution and large-area dynamic image display. However, the existing splicing methods between multiple display screens are all fixed, which is troublesome to install and disassemble, and the fixing effect in the display screen is poor.

[0003] A Chinese patent discloses a sliding door LED display box structure (authorization announcement number CN211047590U). This patented technology can splice four groups of small LED displays into a long strip display by sliding splicing, which can reduce the cost of the LED display while ensuring the display effect; the protective frame adopts an integral type, which has a very good fixing effect on the display;

[0004] However, it has certain disadvantages: when installing, it is necessary to push the spliced ​​display screen into the inside of the protective frame. Due to the large friction between the protective frame and the spliced ​​display screen, it takes a lot of effort to push it during installation, which is time-consuming and labor-intensive, and increases the labor intensity of the staff.
