ABSTRACT:
A method for displaying multi-bit data words on a display including a plurality of pixel electrodes, a plurality of storage elements, a first voltage supply terminal, a second voltage supply terminal, a common electrode, and a plurality of multiplexers each selectively coupling an associated one of the pixel electrodes with one of the first voltage supply terminal and the second voltage supply terminal responsive to a value of a data bit stored in an associated one of said storage elements, includes the steps of sequentially writing each bit of the multi-bit data words to the storage elements, and asserting, while each bit is stored in the storage elements, a first predetermined voltage on the first voltage supply terminal, a second predetermined voltage on the second voltage supply terminal, and a third predetermined voltage on the common electrode, for a time dependent on the significance of the stored bit.
