Abstract
A dual display is disclosed, including a first electrowetting display device and a second electrowetting display device, and a reflection transmission switching device therebetween, wherein the first electrowetting display device and the second electrowetting display device have a function of displaying images and can be switched to a transmissive mode. The invention further provides a dual display, comprising a first substrate, a second substrate opposite the first substrate, a first patterned electrode and a second patterned electrode disposed on the first substrate, a reflective layer disposed on the first patterned electrode, a first patterned hydrophobic layer over the first patterned electrode, a second patterned hydrophobic layer over the second patterned electrode, a wall defining a pixel of the dual display, a first non-polar liquid disposed on the first patterned hydrophobic layer, and a second non-polar liquid disposed on the second patterned hydrophobic layer.
