Abstract:
A display device based on an electro-optical material, the display device operating in response to an information signal, and comprising:analog drive circuits arranged in a two-dimensional array of rows and columns;an analog sampling circuit that derives the analog samples from the information signal; anda sample distribution circuit that receives the analog samples from the analog sampling circuit and distributes the analog samples to the analog drive circuits, the sample distribution circuit including:input gates corresponding to the drive circuits;column busses corresponding to the columns of the array through which the analog samples are distributed column-wise to the analog drive circuits, the analog drive circuits being connected to the column busses by the input gates, anda row selector having outputs corresponding to the rows of the array, each of the outputs being connected to control the input gates in one of the rows, the row selector opening the input gates in the rows sequentially to perform a row-wise selection of the analog samples on the column busses.
