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.
