Problems solved by technology

Because this method uses a control rod through the center point to control the movement mechanism, the movement mode is also limited, and high-resolution transparent display cannot be realized.
[0004] Patent CN200510033694.X also announced a display mode in which a motor drives rollers or gears, then drives a transmission belt or chain, and then drives the movement of display components. Viewers on both sides can see images, but because the LED line array is single-sided, two The image seen by the side viewer is reversed

Abstract

The invention discloses a transparent LED display device. The LED display screen comprises an annular transparent strip, a plurality of rollers in contact with the annular transparent strip, a plurality of LED linear arrays arranged on the annular transparent strip, a driving device, a rotating speed controller electrically connected with the driving device, and a video controller electrically connected with the LED linear arrays. The driving device is connected with a roller, the annular transparent strip is tensioned by the roller, and the LED linear array at least comprises a row of LED lamp bead linear arrays. According to the invention, the LED linear array is arranged on the annular transparent strip, and the LED linear array can display dynamic content through the rotation of the annular transparent strip, so that transparent display is realized, and a better display effect is provided for a user. The invention further provides a naked eye 3D display device.

Description

technical field [0001] The invention relates to an LED display device, in particular to a transparent LED display device and a naked-eye 3D display device. Background technique [0002] Transparent LED display devices have attracted more and more attention in recent years. There are two main implementation methods: the first is to use transparent LED display screens. In fact, the principle of this transparent LED screen is the same as that of ordinary LED screens. , but some improvements have been made to the SMD manufacturing process of the LED light bar, the lamp bead packaging, and the control system. In addition, the hollow design is adopted to reduce the obstruction of the structural components to the line of sight and improve the permeability. There is an irreconcilable contradiction between the clarity and permeability of this transparent device, and it is generally only suitable for some large-scale display devices viewed from a distance. [0003] The second is to u...
