发明名称 IMAGE DISPLAY DEVICE WITH MEMORY
摘要 An image display device having improved image retention capability by analyzing the mechanism behind the creation of an unwanted electric field applied to an element after a power supply is turned off, and devising a drive method and so forth for compensating for the same, is provided. Electrophoretic particles contain three types of charged particles, C (cyan), M (magenta), and Y (yellow) that are mutually different in color and threshold voltage for starting electrophoresis. When the threshold voltages of C (cyan), M (magenta) and Y (yellow) are respectively Vth3, Vth2, and Vth3, these satisfy the relationship |Vth3| < |Vth2| < |Vth1|. Further, a voltage application unit applies a voltage (VE) different from a reference potential during the final period of image update period. The voltage (VE) is a compensation voltage that suppresses the movement of charged particles.
