Abstract
A dual display is disclosed, including a first substrate and a second substrate comprising a plurality of pixels, wherein each pixel comprises a plurality of subpixels. The first substrate comprises a reflective region and a transmissive region for each subpixel, and a first color fluid is movable by an electric field on the reflective region and the transmissive region of a first subpixel, wherein when the first color fluid covers the transmissive region, the dual display provides a first viewing side at the first substrate side under a transmissive mode, and when the first color fluid covers the reflective region or covers the reflective region and the transmissive region, the dual display provides a second viewing side at the second substrate side under a reflective mode.
