Description

Technical Field

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

[0002] LED display is a flat panel display, composed of small LED module panels, used to display text, images, videos and other information. LED electronic display integrates microelectronics technology, computer technology and information processing, and has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation. LED display is widely used in commercial media, cultural performance market, sports stadiums, information dissemination, news release, securities trading, etc., and can meet the needs of different environments.

[0003] During the use of the gantry display screen, it needs to be assembled and spliced. However, the manual assembly and splicing process consumes a long time, increases the burden on the staff, and reduces the overall work efficiency.

[0004] The patent document with publication number CN105204571B discloses a bracket-type display screen, comprising a display screen and a chassis, and also comprising a bracket assembly, wherein the bracket assembly comprises a hardware seat and a multifunctional bracket, wherein the hardware seat is located at the back of the chassis, and the two are connected by threads, and the multifunctional bracket is located at the center of the hardware seat, and the two are rotatably connected. The angle between the two supporting seats of the multifunctional bracket installed on the back of the chassis of this bracket-type display screen can be infinitely changed, which is convenient for transportation, and the bracket as a whole can be rotated to any angle through bearings. When in use, it is only necessary to adjust the angle between the overall bracket and the two supporting seats according to actual needs. When hanging on the wall, it can be completed by directly installing the screws. The long slot hole in the center of the hardware sheet can be conveniently fine-tuned during installation to ensure the level of the display screen. When standing on the desktop, it is only necessary to adjust the angle and tighten the rotating handle to complete it. When installing at other multi-angles, after adjusting the angle, tighten the rotating handle, and then install the screws, and the two can be completed by cooperating with each other.

[0005] The above patent document still has the following deficiencies in practical application: the manual method of fixing and installing the display screen is rather cumbersome, and consumes much time and energy, making the device inconvenient. Based on this, a gantry display screen is proposed. Utility Model Content
