摘要

An electronic display may include a memory formed in an active area of the electronic display or formed in integrated circuitry of the electronic display that is outside of the active area. The memory may store a digital data signal indicative of a value within a data range. The electronic display may include a driver disposed in the active area, where the driver may generate one or more analog electrical signals in response to the digital data signal. The electronic display may also include a light-modulating device disposed on the active area, where the light-modulating device may emit light based at least in part on the one or more analog electrical signals.
