SYSTEMS, DEVICES, AND METHODS FOR DRIVING AN ANALOG INTERFEROMETRIC MODULATOR UTILIZING DC COMMON WITH RESET

摘要

A display apparatus comprising an array of electromechanical display elements and a driver circuit coupled to the array is provided. The driver circuit is configured to apply a DC voltage to a first stationary electrode of the display element and adjust a bias voltage applied to a second stationary electrode of the display element from a first bias voltage to a second bias voltage before a reset period. The driver circuit is further configured to apply a first reset voltage to a movable electrode of the display element during the reset period, apply a write voltage to the movable electrode during a charging period to charge the movable electrode with a charge Q defined at least in part by the write voltage, and adjust the bias voltage applied to the second stationary electrode from the second bias voltage to a third bias voltage during a bias period.
