Image display medium driving device, image display apparatus, driving program, and computer-readable medium
A image display medium driving device includes a voltage application unit that applies a voltage between a pair of substrates, at least one of which is transparent, of an image display medium including plural types of particles which are sealed between the pair of substrates, are attached to the substrates, and start to be separated from the substrates at different times when a predetermined voltage is applied and a control unit that controls the voltage application unit such that a time when the voltage is applied between the pair of substrates varies depending on image information.
1. An image display medium driving device comprising:
a voltage application unit that applies a voltage between a pair of substrates, at least one of which is transparent, of an image display medium which displays an image on the basis of image information and includes a first and second type of particles that are sealed between the pair of substrates, have different colors, and have different adhesive forces for maintaining attachment to the substrates; and
a control unit that controls the voltage application unit and is configured to apply a voltage level between the pair of substrates for a first duration to separate the first type of particles from one of the substrates on the basis of the image information, apply the voltage level between the pair of substrates for a second duration to separate the second type of particles from the one substrate on the basis of the image information, and wherein the second duration is greater than the first duration.
2. The image display medium driving device according to claim 1 ,
wherein at least some of the first type of particles are separated from the substrate on the basis of the image information.
3. The image display medium driving device according to claim 1 ,
wherein at least some of a second type of particles are separated from the one substrate and the control unit is further configured to reverse the polarity and apply the voltage level until at least some of the first type of particles are separated from a second substrate of the pair of substrates on the basis of the image information.
4. An image display apparatus comprising:
the image display medium; and
the image display medium driving device according to claim 1 .
