Abstract
A display comprises an encapsulated display media addressed by an organic-based field effect transistor. The display media comprises a plurality of particles and a fluid. The field effect transistor comprises an organic semiconductor.
Claims55
A display comprising:
- an encapsulated display medium comprising a plurality of capsules each of which comprises at least one particle and a fluid, the display medium having a first surface and an opposed second surface, the display providing an image for viewing via one of the first and second surfaces;
- and
- an organic-based field effect transistor comprising an organic semiconductor, the organic-based field effect transistor disposed on the second surface of the display medium so as to be capable of addressing the display medium.
A display comprising:
- an encapsulated display medium comprising a plurality of capsules each of which comprises at least one particle and a fluid, the display medium having a first surface and an opposed second surface, the display providing an image for viewing via one of the first and second surfaces;
- an organic-based field effect transistor comprising an organic semiconductor, the organic-based field effect transistor disposed adjacent the second surface of the display medium so as to be capable of addressing the display medium;
- and
- a barrier layer disposed between the encapsulated display medium and the organic-based field effect transistor.
