Abstract :
The idea of cross pairing of select and data voltages in line-by-line addressing is extended for multi-line addressing; to display a large number of gray scales with a small number of time intervals as compared to successive approximation technique. The method is illustrated by selecting two rows at a time with waveforms based on Hadamard matrix.
