Holographic visualisation system comprising a high data refresh rate DND driver array

摘要

A DND chip comprises 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 architecture comprising a set of first drive lines (scan lines SL) along the rows of DND elements and a set of second drive lines (local pixel lines LPL) along the columns of DND elements; a set of first line drivers (scan line drivers SLD) for each biasing one line from the set of first drive lines and a set of second line drivers (pixel line drivers PLD) for each biasing a line from the set of second drive lines. A plurality of second line drivers (pixel line drivers PLD) 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 comprising such a DND chip is also provided.
