Abstract: A display system may include a memory external to a pixel that stores a first digital data value, a memory internal to the pixel that stores a second digital data signal, where a combination of the first digital data signal and the second digital data signal may indicate a target gray level assigned to the pixel for a particular image frame. The pixel may be driven for a first duration of time according to the first digital data signal and for a second duration of time according to the second digital data signal.

Abstract: A device may include an electronic display to display image frames. The display may include illuminators that generate light and mirrors that selectively direct the light to pixel locations based bitplanes that set the arrangement of the mirrors. Additionally, the device may include duty cycle balancing circuitry that generates and provides duty cycle balancing signals to the electronic display. In response to the duty cycle balancing signals, the electronic display is implements balancing on bitplanes during at least a first portion of off periods during the image frames and implements balancing off bitplanes during at least a second portion of the off periods such that, in the aggregate, a ratio of respective on times of the mirrors to respective off times of the mirrors is balanced across the image frames during the off periods.

Abstract: A pixel circuit for an electronic display may include a memory to store a digital data signal indicative of a value within a data range. The pixel circuit may also include a light-emitting diode to emit light based at least in part on the digital data signal. The pixel circuit may also include an initialization transistor to initialize the pixel circuit before the light-emitting diode emits light and a driving transistor to activate based at least in part on the digital data signal.
