Patent ID: 7940257

Claim:
A method for processing a data signal in a LCD driver system, comprising the steps of: providing data to a SEG decoder; providing an array signal to the SEG decoder; SEG decoding the data and the array signal, comprising the substeps of: performing an inverse operation on the array signal; performing an XOR operation on the inversed array signal and the data; and level selecting a decoded signal as a function of the output of the XOR operation; break-before-make processing the decoded signal; level shifting the to break before make-processed signal; level selecting the level-shifted signal; and sending the level-selected signal to a display panel; wherein in using said XOR operation, the SEG decoder comprises of a signal processor, a decoder circuit and a level control selector; wherein the signal processor comprises three identical 2-to-1 multiplexer and three identical phase inverters; wherein the decoder contains three identical XOR gates; and wherein the level control selector comprises XOR gates, three NAND gates and also a phase inverter.
