Dual display

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 first non-polar liquid disposed on the first patterned hydrophobic layer;
• and
• a second non-polar liquid disposed on the second patterned hydrophobic layer wherein a side of the first substrate provides a first display device facing a first viewing side and a side of the second substrate provides a second display facing a second viewing side.

A dual display, comprising:

• a first display device and a second display device;
• and
• a reflection transmission switching device between the first display device and the second display device, wherein when the first and second display device and the reflection transmission switching device are switched to a transmissive mode, the entire dual display is transparent;
• when the reflection transmission switching device is switched to a reflective mode, the first and second display devices can display different images, and
• when the reflection transmission switching device is switched to a transflective mode, the first and second display devices can be presented as a transmissive display and a reflective display respectively, wherein the first display device faces a first viewing side and the second display device faces a second viewing side.
