Abstract
Novel addressing schemes for controlling electronically addressable displays include a scheme for rear-addressing displays, which allows for in-plane switching of the display material. Other schemes include a rear-addressing scheme which uses a retroreflecting surface to enable greater viewing angle and contrast. Another scheme includes an electrode structure that facilitates manufacture and control of a color display. Another electrode structure facilitates addressing a display using an electrostatic stylus. Methods of using the disclosed electrode structures are also disclosed. Another scheme includes devices combining display materials with silicon transistor addressing structures.
Claims21
A display comprising:
- an electrophoretic display medium comprising a polymeric matrix defining a plurality of voids wherein at least one void contains an electrophoretic fluid;
- at least one electrode disposed adjacent to the electrophoretic display medium for addressing the electrophoretic display medium;
- at least one conductor for applying an addressing voltage to the at least one electrode;
- and
- a substrate disposed between the at least one electrode and the at least one conductor, the substrate defining at least one via therethrough for providing electrical communication between the at least one electrode and the at least one conductor.
A display comprising:
- an electrophoretic display medium;
- and
- an active-matrix-addressing backplane disposed adjacent to the electrophoretic display medium, the active-matrix-addressing backplane comprising:
- at least one electrode for addressing the electrophoretic display medium;
- at least one nonlinear element for applying an addressing voltage to the at least one electrode;
- and
- a substrate disposed between the at least one electrode and the at least one nonlinear element, the substrate defining at least one via for providing electrical communication between the at least one electrode and the at least one nonlinear element.
