ABSTRACT:
A data communication receiver (605) receives and stores a set of image data and displays images associated therewith on a display (600') having rows divided into first and second segments (705, 710). The data communication receiver (605) comprises a database (635) for storing a set of orthonormal functions and row drivers (650) coupled to the database (635) for driving the first segment (705) of the display (600') with first voltages associated with a first subset of orthonormal functions and driving the second segment (710) of the display (600') with second voltages associated with a remaining function included in the set of orthonormal functions during a first plurality of sequential time slots. The row drivers (650) also drive the first segment (705) with the second voltages associated with the remaining function and drive the second segment (710) with the first voltages associated with the first subset of orthonormal functions during a second plurality of sequential time slots.
