Display content on mobile device by movement

Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty -fifth of a second on the retina.

By leveraging persistence of vision principle, there are many inventions on displaying image by moving lighting rod or other display devices. Below is a list of related patents. E6%A3%92&hl=en&sa=X&ei=_gW4UrCiC4fMsQTYy4KoBw&ved=0CDcQ6AEwAA

However, the prior arts have some limitations

1. Each mobile device has different screen display size. In the prior art, the display size is fixed.

2. Size of display content may be two large or two small. In the prior arts, they only can display certain size of image. This invention presents a method/system of display image/text on mobile device by movement:

1. Display size is calculated dynamically.

2. Display area is adjust dynamically
