Data conduction extension device for turnover light-emitting diode (LED) studio screen

Abstract

The invention discloses a data conduction extension device for a turnover light-emitting diode (LED) studio screen and relates to a turnover LED display screen. The data conduction extension device for the turnover LED studio screen is characterized by consisting of a rotor and a stator; the rotor and the stator are arranged between an upper layer LED triangular module and a lower layer LED triangular module, so that the upper layer LED triangular module and the lower layer LED triangular module synchronously rotate; the rotor is provided with a combined slip ring; the combined slip ring is connected with an output data line and is led out into an inner cavity of the lower layer LED triangular module; the stator is provided with an electric brush module at the inner side of a hollow sting; the electric brush module is connected with an input data line, is led out to the outside and is connected with peripheral equipment; the combined slip ring and the electric brush module are correspondingly contacted in the inner cavity of the hollow sting of the stator to form information conduction between a fixed object and a rotary object; externally input data information is transmitted to the inner cavity of the lower layer LED triangular module; and the combined slip ring is connected with LED light bars of the lower layer LED triangular module. According to the extension device disclosed by the invention, multi-way information transmission between the fixed object and the rotary object is realized and not only is the problem that a wire is wound solved but also the image playback quality of an ultrahigh LED digital studio screen can be improved through the image mosaicking technology.

Description

technical field [0001] The invention relates to the technical field of LED digital broadcasting. More specifically, it relates to flip-up LED displays. Background technique [0002] Existing flip-type LED display screens include LED three-side flip screens and LED double-side flip screens. The display body is composed of multiple LED triangular modules arranged vertically, and there are decorative frames around them. The upper end of the LED triangular modules It is connected with the inner panel of the decorative frame, the lower end is connected with the power drive device, and rotates according to the set rule. The LED triangular module is installed with multiple LED display modules on any surface of the aluminum alloy triangular tube. It is made of aluminum The length of the profile is limited. At present, the height of this type of advertising equipment is limited to less than 8 meters, which is far from meeting the market demand. [0003] Chinese patent CN2018534...

[0002] Existing flip-type LED display screens include LED three-side flip screens and LED double-side flip screens. The display body is composed of multiple LED triangular modules arranged vertically, and there are decorative frames around them. The upper end of the LED triangular modules It is connected with the inner panel of the decorative frame, the lower end is connected with the power drive device, and rotates according to the set rule. The LED triangular module is installed with multiple LED display modules on any surface of the aluminum alloy triangular tube. It is made of aluminum The length of the profile is limited. At present, the height of this type of advertising equipment is limited to within 8 meters, which is far from meeting the market demand

[0003] Chinese patent CN201853456.U discloses a "super-high LED double-sided billboard". The patent describes "the upper end cover and the lower end cover are fixedly connected by a connecting mechanism; the connecting mechanism is provided on the upper end cover. The connecting rod and the opening set in the middle of the lower end cover; the connecting rod is a hollow connecting rod", which realizes the function of connecting heights of this type of equipment, but it is only a connecting mechanism with a wire hole, and its data information is still Access from the upper port and extend from top to bottom through the hollow connecting rod; therefore, there are the following disadvantages: First, the higher the height, the more physical pixels of the display screen, when the physical pixels exceed a certain When the number is large, the image refresh frequency will be reduced, and it may even fail to work; second, as the number of physical pixels increases, the power supply current will increase, and the greater the current, the greater the line resistance, and the greater the voltage difference; the third is that fixed objects and The rotating objects are directly connected by wires. Once the machine loses control, the wires will be wound and the wires will be damaged.
