    (POV显示器)
    藉由快速切换指示灯的开关,利用视觉暂留的原理
    原因是由视神经的反应速度造成的,其时值什么二十四分之一秒。
    在空中不存在的大画面64x16的点阵上,摇出文字

    物体在快速运动时,当看到的影像消失后,
    人眼仍能继续保留其影像,约0.1-0.4秒左右的图像,
    这种现象被称为视觉暂留现象

    What is POV Display:
    A class of display device described as "POV" is one that composes an image by displaying one spatial portion at a time in rapid succession (for example, one column of pixels every few milliseconds). A 2 dimensional POV display is often accomplished by means of rapidly moving a single row of LEDs along a linear or circular path. The effect is that the image is perceived as a whole by the viewer as long as the entire path is completed during the visual persistence time of the human eye. A further effect is often to give the illusion of the image floating in mid-air.
