<P>PROBLEM TO BE SOLVED: To prevent contents displayed on a display screen from being easily imaged intact by an imaging means. <P>SOLUTION: When no light enters the front side of an electrophoresis display (YES in step S102), all the pixels of the electrophoresis display become white (step S103). Accordingly, when the front side of the electrophoresis display is placed on the contact glass of a copying machine in order to copy the content displayed on the electrophoresis display, the whole content displayed on the electrophoresis display is erased, so that it is possible to prevent easily copying of the content displayed on the electrophoresis display by the copying machine. <P>COPYRIGHT: (C)2010,JPO&INPIT |
