    Abstract: The present invention provides four-particle electrophoretic displays with improved driving methods to achieve better color separation between adjacent pixel electrodes. The driving methods improve the color state performance when a first pixel is displaying a mixed state of a first highly-charged particle and a second lower-charged particle of the opposite polarity, while a neighboring pixel is displaying a state of a second highly-charged particle having the opposite polarity to the first highly-charged particle. The particles can be, for example, all reflective or one type of particle can be partially light transmissive.

  • Publication number: 20130085712
    Abstract: An inertial sensing input apparatus includes a motion sensing module, a state determination module, an attitude estimation module, a coordinate transformation module, a gravity elimination module, an integral operation module, a data storage module, a trajectory modification module and a trajectory removal module. When the inertial sensing input apparatus is in a moving time period, the coordinate transformation module transforms a relative acceleration measured by the motion sensing module to an absolute acceleration based on a rotational attitude estimated by the attitude estimation module. The integral operation module calculates a velocity and a displacement based on an absolute acceleration revised by the gravity elimination module and forwards them to the data storage module. When the Kth moving time period is detected by the state determination module, the trajectory modification module modifies a moving trajectory.
