METHOD AND APPARATUS FOR STORING COMPRESSED DATA FOR SUBSEQUENT PRESENTATION ON AN ACTIVE ADDRESSED DISPLAY

摘要

An electronic device (55) for driving an active-addressed display (100) comprises a data port (505) for receiving image data and compression circuitry (530) coupled to the data port (505) for generating compressed data by compressing the image data using a method in which the image data is two-dimensionally transformed utilizing a plurality of orthonormal, i.e., orthogonal and normalized, functions. The electronic device (500) further comprises transforming circuitry (515) coupled to the compressing circuitry (530) for performing a one-dimensional transformation of the compressed data using the orthonormal functions to generate a set of column values. Column drivers (565) coupled to the transforming circuitry (515) and the active-addressed display (100) drive columns of the active-addressed display (100) with analog voltages corresponding to the set of column values.
