IPC: G02F1/17
Filed: 2008-06-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a display device which is capable of reducing the power consumption while preventing the degradation of display.  <P>SOLUTION: The display device includes a display panel 30 having an electrophoretic element, and a driving control means 40 controlling display on the display panel 30.

When a display magnification is small, the degradation of display can be prevented by shortening the refresh time interval because the degradation of display is apt to occur due to the reduction in contrast of lines constituting an image. Meanwhile, a high display magnification, the degradation of display is difficult to occur because the lines constituting the image are thick, and therefore, the power consumption can be reduced by extending the refresh time interval. The power consumption can be minimized within a range wherein display quality can be maintained, since the refresh time interval is changed in accordance with display contents.  <P>COPYRIGHT: (C)2010,JPO&INPIT
