Abstract
Reflective image display architecture embodiments are disclosed comprising a perforated continuous reflective sheet. The perforated continuous sheet comprises a coating that provides a threshold to particle movement. The coating may be designed to provide a passive or electro-active physical barrier. The coating improves bistability of the display.
Claims19
A reflective image display, comprising:
- a front electrode;
- a rear electrode, the front and the rear electrode forming a gap therebetween;
- a transparent medium disposed in the gap;
- a plurality of mobile electrophoretic particles dispersed in the transparent medium and movable within the gap;
- and
- a barrier interposed between the front electrode and the rear electrode, the barrier configured to permit movement of at least one electrophoretic particle from the front electrode to the rear electrode.
3 more elements
A method for displaying a reflective image, the method comprising:
- positioning at least one charged electrophoretic particle in a transparent medium disposed between a front electrode and a rear electrode;
- biasing the front electrode relative to the rear electrode with a first voltage to form an electromagnetic field therebetween thereby attracting the at least one charged electrophoretic particle to one of the front electrode or the rear electrode;
- and
- stimulating a barrier layer relative to one or more of the first or the second electrode to expedite movement of the at least one electrophoretic particle from the front electrode to the rear electrode.
1 more element
A non-transitory computer-readable storage device having a set of instructions to cause a processor to perform a process comprising:
- affecting movement of at least one charged electrophoretic particle in a transparent medium disposed between a front electrode and a rear electrode;
- biasing the front electrode relative to the rear electrode with a first voltage to form an electromagnetic field therebetween thereby attracting the at least one charged electrophoretic particle to one of the front electrode or the rear electrode;
- and
- stimulating a barrier layer relative to one or more of the first or the second electrode to expedite movement of the at least one electrophoretic particle from the front electrode to the rear electrode.
