Patent ID: 6876349

Claim:
A matrix display device comprising: a matrix of picture elements at crossings of selection electrodes that select rows of picture elements, and column electrodes that provide date, a row driver that is configured to provide selection signals to the selection electrodes, a column driver that is configured to provide data signals to the column electrodes, and a charge redistribution digital to analog converter that is configured to convert a multi-bit digital data signal into an analog signal on at least one of the column electrodes, wherein the digital to analog converter includes a capacitance of one or more column electrodes, and the digital to analog converter is configured to apply a binary voltage signal corresponding to each bit of the multi-bit digital data signal to at least a sub-electrode of the one or more column electrodes, the sub-electrode of the one or more column electrodes forming at least one of the crossings of selection electrodes and column electrodes.
