Abstract
An active-matrix electronic display including a switching circuit for each pixel to control the optical state of the display. The switching circuit includes at least one diode and at least one load impedance for each circuit. The front plane electrode of the display may be unpatterned over a significant portion of the display. The display architecture is especially useful for bi-stable display media that require active matrix addressing, for example electrophoretic displays, and for applications using diodes based on organic semiconductors and/or printed diodes.
