A DND chip is disclosed. In one aspect, the chip includes a 2D DND array of DND elements logically arranged in rows and columns, and a DND driver architecture for actuating the DND elements. The DND driver has a set of first drive lines along the rows and a set of second drive lines along the columns, a set of first line drivers for each biasing one line from the set of first drive lines and a set of second line drivers for each biasing a line from the set of second drive lines. A plurality of second line drivers are spatially grouped together to serve a block of DND elements, and that plurality of second line drivers are spatially covered substantially completely by at least some DND elements of the block of DND elements. A holographic visualization system including the DND chip is provided.
