Electrophoretic display device and method for driving same

A method for driving an electrophoretic display device, wherein the electrophoretic display device comprises a first substrate, a second substrate opposite to the first substrate, a first electrode disposed on the first substrate, a second electrode disposed on the second substrate, a plurality of charged particles disposed in between the first and second substrates, and a sensor, comprising:

• sensing or detecting a usage status of the electrophoretic display device or one or more environmental parameters associated with a surrounding environment of the electrophoretic display device;
• and
• in accordance with the usage status or the one or more environmental parameters sensed or detected, generating either an electric field to cause the plurality of charged particles to move imagewise toward and to contact with at least one of the first and second electrodes or another electric field to cause the plurality of charged particles to move non-imagewise and substantially away from the first and second electrodes so as to form a substantially non-imagewise bistable state.
