本文介紹一低價位360度環場彩色LED顯示系統。不像傳統LED顯示，此彩色LED顯示系統只用一排高亮度三基色LED，利用視覺暫留的原理，以精密控制旋轉機構時空雙重多工方式來實現彩色360∘環場顯示功能，其快速的影像掃描頻率（26畫面每秒）與旋轉速度（516.8 rpm）使鮮艷明亮的影像能穩定地從任何角度都可欣賞。

This paper is to introduce a low-cost 360-degree surround color light-emitting diode display system. Unlike conventional light-emitting diode display, the 360-degree surround color light-emitting diode display system employs both rotating scan scheme and a precision control in combination of time and space to provide three same screen displays with only one column of tricolor (Red, Green, Blue) light-emitting diodes. The frequency of image scan (26 frames/sec) and the speed of rotation (516.8rpm) are high enough to be indistinguishable by human eyes, hence display appears to be constantly illuminated and the brilliant color image can be seen from any view of angle.
