Patent ID: 8487855

Claim:
A system to drive a matrix display using wavelets based addressing technique to reduce a number of time intervals for DC free operation, to reduce hardware of data drivers and to lower a supply voltage of display drivers, said system comprising: a voltage level generator to provide predetermined voltages based on wavelets, wherein the wavelets are chosen based on gray shade data bits to form a wavelet matrix, a row voltage selector to select a group of voltages from the voltage level generator as input voltages to a plurality of row drivers, wherein the selected group of voltages depend on select vector which is a column in the wavelet matrix; a column voltage selector to select a group of voltages from the voltage level generator as input voltages to a plurality of column drivers, the selected group of voltages depend on the select vector; and a controller to generate control signals to drive the matrix display using wavelets based on a predetermined addressing technique, thereby reducing the number of time intervals for DC free operation, reducing hardware of data drivers and lowering the supply voltage of display drivers; wherein the row voltage selector and the column voltage selector select the group of voltages applied to the row drivers and the column drivers.
