Abstract

The invention relates to a rotary multi-linear array high definition LED flat and stereoscopic display which comprises an LED linear array structure and a rotary cylinder display substrate which can rotate at a uniform speed, and a double linear array LED or an LED linear array set in different turning radius is arranged on the rotary cylinder display substrate. A double linear array structure is adopted on the linear array with the same turning radius. LEDs of every two linear arrays are staggered by a unit to display corresponding interlaced information at the same time respectively; LED linear arrays are arranged in different turning radius to realize stereo display; and a rotary encoder is adopted to provide line-scanning signals. The invention has the advantages that the rotary multi-linear array high definition LED flat and stereoscopic display can improve the definition remarkably and realize stereo display; a plurality of channels can be played within 360 degrees; the problem of display asynchronization can not produced under the conditions that the rotary speed of a motor is affected by power frequency or other factors; and the drive proposal is simple and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of LED line array structures and stereoscopic displays, in particular to a multi-line array high-definition LED plane and stereoscopic display based on rotation. Background technique [0002] At present, large-scale indoor and outdoor advertising and video playback systems are mainly LED surface array structures. Due to the huge screen, the number of LEDs required is very large, which makes the structure complex, expensive, and consumes a lot of electricity; and due to the discrete characteristics of LEDs and the installation process The limitation makes it difficult to further improve the brightness uniformity and resolution of the picture. As we all know, most monitors obtain images by row-column scanning, as long as the scanning time of an image is less than the persistence time of human vision, there will be no flickering. Using the line scanning formed by the uniform rotation of the cylindrical rotatin...
