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.

Abstract: A plurality of X electrodes and a plurality of Y electrodes arranged on a support substrate of the tactile sense presentation device are divided into M groups (here, M?2, M=4 in FIG. 14). When a presentation content of a tactile sense transits from the N-th frame to the (N+1)-th frame, the tactile sense presentation device, first, sets electrodes belonging to a group 1 to a floating state for a predetermined time and then, connects each electrode to an AC voltage signal source or the ground so as to present a tactile sense in the (N+1)-th frame. The tactile sense presentation device sequentially performs this operation for each group, and, when the operation of a group M ends, a transition between frames ends, and the movement of the target area that is an area in which a texture sense is presented is completed. There is no case where all the electrodes are in the floating state together, and there is no interruption of the texture sense.

Abstract: A display device has a data-holding circuit with a capacitance and a display portion with a plurality of pixel electrodes, formed on a first carrier substrate. In the display device, a second carrier substrate disposed opposite the first carrier substrate is placed above the display portion, but the opposing substrate is not present above the area in which the data-holding circuit is disposed.

The display data of all the pixels is sent serially to the liquid crystal module without high-speed transfer for each frame time interval, and size can be reduced because the controller IC and interface circuit are formed on the same substrate as the display device substrate.
