Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rotary display device, and more particularly, to a rotary display device that is attached to a pillar and that is provided to surround a pillar so as to generate a 360-degree panoramic image.
[0002]
[Prior art]
Light emitting diodes (hereinafter, referred to as “LEDs”) are used in conventional large display devices (often hundreds of thousands of LEDs are used). Higher resolution display devices require more LEDs. Increasing the number of LEDs not only increases their cost, but also increases the likelihood that the display will have faulty elements. To solve this problem, Taiwan Patent Application No. 85,202,605 and U.S. Pat. And Chinese Patent No. ZL962229136. In these patent applications, a plurality of rows of light emitting devices are mounted on a rotating body at equal distances or at equal angles. Each row of light emitting devices includes a number of light emitting sources. As the rotator rotates, the different light sources of each light emitting device are excited at different spatial locations. As a result of the afterimage of the image that occurs to the human eye, a virtual display is created on the rotating surface of the rotating body.
[0003]
By significantly reducing the number of LEDs required in the aforementioned applications, and thus reducing the likelihood of having a faulty element, the invention of each application is disclosed in Taiwan Patent No. 120,003 and US Patent No. 5,818. , 401 and Chinese Patent No. 96229136.
[0004]
From the above description, it can be understood that by dividing the spatiotemporal space and using the afterimage of the human eye, relatively few light emitting devices are required for the rotating body to form the virtual display. However, existing rotary display devices can only be used as stand-alone devices. Conventional flat large display devices are mounted on walls of large buildings to display images. If the rotating display is similarly mounted around a pillar in a building, its application can be extended widely.
