Abstract
A digital micro-mirror device (20) for imaging applications, having an array (21) of mirror elements for forming the image, and having data loading circuitry (22, 23) for loading data for addressing the mirror elements. The data loading circuitry (22, 23) has a row of shift registers (23), which receive data and pass the data to latches (22). Each output of the shift registers (23) is connected to a number of latches (22). For loading a row of data, the row is divided into portions, and the shift registers (23) receive the row of data in sequential portions. It delivers each portion to a different set of latches, each set comprised of a latch from each shift register output. Each set of latches holds its portion of the row of data on bit-lines while the remaining portions of the row are input to the shift registers (23) and passed to other sets of latches (22).
