Reflective electrophoretic display with laterally adjacent color cells using an absorbing panel |
摘要 |
An ambient light reflective color electrophoretic display is comprised of a plurality of color pixels; each comprised of at least two electrophoretic cells. Each cell is comprised of a suspension of charged, white or colored light-scattering pigment particles in a light-transmissive fluid. Each cell is also comprised of a light-transmissive front window, at least one non-obstructing counter electrode, at least one non-obstructing collecting electrode, a light-absorbing panel, and a color filter medium. The cells of different colors are in a laterally adjacent relationship to each other and the charged pigment particles are responsive to the electrodes. The filter medium in each cell can be a light-transmissive color filter element. Alternatively, the pigment suspension fluid itself or the pigment particles themselves can be colored and serve as the filter medium.
