Abstract:
A display device comprising an array of liquid crystal pixels, each pixel comprising a thin film transistor switching device and a liquid crystal cell, the array being arranged in rows and columns, wherein each row of pixels shares a row conductor, which connects to the gates of the thin film transistors of the pixels in the row, and wherein each column of pixels shares a column conductor to which pixel drive signals are provided, wherein row driver circuitry provides row address signals for controlling the switching of the transistors of the pixels of the row, and column address circuitry provides the pixel drive signals, wherein the row address signals comprise a plurality of voltage levels, and wherein the column address circuitry comprises circuitry for generating representations of at least some of the row address voltage levels, and wherein the row address circuitry comprises a conversion circuit for converting the representations into the row address levels.
