Abstract
A digital micro-mirror device (20) for imaging applications, having an array (21) of mirror elements for forming the image and data loading circuitry (22, 23, 24) for loading data for addressing the mirror elements. The data loading circuitry (22, 23, 24) has a row of shift registers (24), which receive one row of data at a time, which they deliver to latches (23). The latches (23) hold the data on bit-lines, which run down columns of the array (21). The row to be loaded is selected with a row decoder (25). A block load circuit (22), comprised of a shift register (35) and logic gates (33) divides each row of memory cells into blocks (31) and ensures that each block of a row of memory cells is sequentially loaded.
