Rotary type LED display screen

Abstract

The invention relates to the technical field of LED display screens, and discloses a rotary LED display screen, which includes an LED rotary column display screen, a rectangular circuit board, a rotating shaft and a stepping motor, and the LED rotary column display screen is arranged in the center of the rectangular circuit board position, the stepper motor is connected to the lower part of the rectangular circuit board through the rotating shaft, an LED driver module is packaged on one side of the rectangular circuit board, and a second microcontroller and a second wireless transceiver are packaged on the other side of the rectangular circuit board. One side of the motor is provided with a first microcontroller and a first wireless transceiver connected to each other, the first wireless transceiver is wirelessly connected to the second wireless transceiver, the second wireless transceiver is connected to the second microcontroller, and the second wireless transceiver is connected to the second microcontroller. The second microcontroller is connected with the LED driving module, and the LED driving module is connected with the LED rotating column display. The invention adopts a rectangular circuit board, and when the circuit board is laid out, it is convenient to ensure that the rotating shaft is directly facing the center of gravity of the rectangular circuit board, so as to avoid rotation during rotation and make the rotation more stable.

Description

technical field [0001] The present invention relates to the technical field of LED display screens, and more specifically relates to a rotating LED display screen. Background technique [0002] LED displays have been widely used in public places such as advertisements, stations, banks, shopping malls, etc. It has the advantages of low power consumption, long life, and good colors. The light-emitting devices of the existing LED display screens mainly use LED flat panel modules. This type of display screen mainly has two problems that need to be improved: firstly, the entire display screen is composed of LED modules, with a large number of components and high cost; in addition, due to The display screen is a plane, and LED pixels have certain viewing angle restrictions, so that the visible range of the display screen is limited to a certain range on the front, and the information release of the display screen is subject to certain space restrictions in the application.

AI Technical Summary

Problems solved by technology

If the center of gravity of the rotation is not on the shaft, it will vibrate violently during high-speed rotation, and under the huge centrifugal force, the whole system will be disassembled, causing safety hazards

Disc-shaped circuit boards are generally used in the prior art. However, due to the packaging and weight of electronic devices, the center of gravity of the disc circuit board is unevenly distributed, which is difficult to adjust.
