US-12628298-B2 - LED display device with highly effective installation

Abstract

The invention presents an LED display device featuring a highly efficient installation method. It consists of display screens arranged in a matrix, with adjacent screens connected via a rapid assembly. This assembly includes a motor screw structure affixed to one screen and a nut structure fixed to the adjacent screen. The motor screw structure incorporates a deceleration motor and a screw fixed on the screen, while the nut structure comprises a nut fixed on the screen via a mounting plate. During assembly, power is applied only after alignment, allowing the deceleration motor to rotate the screw. The nut then adjusts the distance between screens until installation requirements are met, enhancing installation efficiency.

Description

TECHNICAL FIELD The invention relates to the technical field of LED display equipment, in particular to an LED display device with a highly effective installation. BACKGROUND ART The LED display device is an electronic display device composed of LED lattices, it changes the screen display content forms such as text, animation, pictures, and video by turning on and off the red and green lights, thereby realizing the transformation between different forms of various information presentation modes, and it can be used indoors and outdoors, which has incomparable advantages over other display devices. With the advantages of high brightness intensity, low power consumption, low voltage demand, small and portable size, long service life, stable impact resistance, and strong resistance to external interference, it has developed rapidly and is widely used in various fields. At the same time, with the development of scientific and technological information, the progress of video technology has been promoted, and the screen display of video has been widely used in outdoor advertising, public transportation, publicity exhibitions, and other fields. In order to increase the publicity effect, multiple display screens need to be assembled together to realize the video display of the same screen. The existing multiple display screens are generally fixed to a specific position of the same installation frame by manual operation, this fixation method has the following defects: (1) Low installation efficiency, the installation speed of general conventional LED display equipment is about 1 m2/37 minutes; (2) The installation accuracy should be strictly controlled. Once a large error appears, it will cause some display screens to exceed the installation frame, resulting in unstable installation; (3) After the installation is completed, the distance between the adjacent display screens cannot be adjusted according to the needs of customers, and the use is not flexible. SUMMARY In order to solve the above problems, the invention provides an LED display device with a highly effective installation, which connects two adjacent display screens through a fast assembly, during the assembly, the power supply is turned on only after alignment, and the deceleration motor can drive the screw to rotate, the distance between the two display screens can be shortened with the nut until the installation requirements are met, which improves the installation efficiency.
