Collapsible rotatory demonstration LED lamp plate

Technical Field

The utility model relates to a video display field, especially a collapsible rotatory demonstration LED lamp plate.

Background

The rotating LED display screen is also called as a rotating array LED screen, a motor with constant rotating speed drives one or more rows of LEDs to rotate, and meanwhile, the control circuit synchronously controls the lighting state of the LEDs, so that the display content of the LEDs is changed once when the motor rotates by a certain angle, and the unique determined display content exists at any position when the motor rotates. The content displayed at each position is redisplayed after 50 mm. By utilizing the physiological characteristic of 'persistence of vision', that when human eyes observe an object, the visual image does not disappear immediately after the object leaves, and the image still stays in the human vision for a short time (about 80 mm), people feel that the content displayed at each position of the linear array LED in the 360-degree range of the rotation of the motor exists at the same time, so that the image and the characters are displayed on the rotating plane of the linear array LED.

At present, a rotary LED display screen is often used for naked eye stereoscopic image advertisement.
