Abstract
An electro-optic display device includes a display matrix of display pixels. Each display pixel may include two or more first sub-pixels and a second sub-pixel. Each first sub-pixel may have two or more display states and a color filter. The second sub-pixel may have two or more display states and a white filter. The first sub-pixels may be arranged in rows and columns in a repeating pattern, and each first sub-pixel may be horizontally adjacent and vertically adjacent to one or more second sub-pixels. In addition, a display controller may include a data switch, a color correction module, an image filtering module, a color linearization module, an image dithering module, and a saturation adjustment module. The modules may be configured to perform operations at first and second pixel resolutions.
