Abstract
The disclosure describes various aspects of backplanes, including unit cells, architectures, and operations. In an aspect, a backplane unit cell is described that includes first and second switches, a storage element, a comparator, a source (e.g., a current or voltage source), where the source generates a drive signal to control light emission of a selected one of the light emitting elements in a display, and where the drive signal is based on a power signal selected by the second switch. In another aspect, a device is described that includes a backplane configured in an active matrix topology including multiple data columns and multiple row selects; and a set of electrical contacts associated with the active matrix topology and configured to electrically couple the backplane with the display, the display having multiple light emitting elements configured in a passive matrix topology. Methods of operation of the backplane are also described.
