In-plane electrophoretics is attracting increasing attention, because it can provide bright color and/or transparent displays in combination with ultralow power consumption. Besides display applications, this enables novel applications such as smart windows, electronic skins, electronic wallpaper, and digital signage (as a replacement for color-printed paper signs). This chapter gives an overview of the developments in the field for nonmatrix, passive-matrix, as well as active-matrix devices. The latest concepts for grayscale and multicolor are also presented.
