DISPLAY DEVICE AND ELECTRONIC EQUIPMENT USING THE SAME |
摘要 |
PROBLEM TO BE SOLVED: To provide an active matrix type electrophoretic display device which is smaller in writing frequency. SOLUTION: The electrophoretic display device which displays video by using an n-bit digital video signal has each pixel divided into a plurality of subpixels, which each have a one-bit memory circuit. An electrophoretic element can omit cyclic refreshing operation which is normally necessary since a state of writing which is completed once is stable and an image is held with a digital video signal held in the memory circuit when a still picture display is made.
