<p>PURPOSE:To attain a precise input without giving unnatural feelings due to the difference between a display part and an input part at the time of input by writing information in a display medium itself so as to input it. CONSTITUTION:A drive layer 503 composed of a display layer 502 and a resistance heating body is sandwiched by protection layers 501. A current is caused to flow at a designated position on the drive layer 503 where a pattern is cut in a segment-like shape, and the drive layer 503 composed of the resistance heating body heats and rapidly cools the display layer 502. Consequently the hue of a part 504 is changed and information is displayed. Since the display medium applying an optical recording material has a recording action, it needs not current to flow in the drive layer 503 if the same information is continuously recorded. However, if the displayed information is erased, said medium is heated lower than at display.</p> |
