Actuated mirror array driving circuit having a DAC

摘要

A circuit for driving a number of actuated mirrors in a column in an actuated mirror array includes a sequential circuit for generating a sequential signal, a corresponding number of latches and a corresponding number of digital-analog converters, wherein a data signal is latched in sequence in each of the latches and each of the data signals latched in the latches is simultaneously provided to an analog-digital converter which converts the data signal into any one of many different gradation values over a given range.
