Abstract
An electrophoretic display panel for displaying a picture has a pixel having an electrophorectic medium having first and second charged particles, the first charged particles having a first optical property, the second charged particles having a second optical property different from the first optical property, and an optical state depending on positions of the particles. Furthermore, particle movement apparatus is arranged to enable a picture movement of the first and the second particles to their respective position for displaying the picture, and particles movement decoupling apparatus is arranged to provide unequal abilities of the first and the second particles to move for substantially decoupling the picture movement of the first particles from the picture movement of the second particles.
