— Methods to reduce the power dissipation and supply voltage of LCD drivers for several line‐by‐line addressing techniques ( viz. , addressing based on Hadamard matrices, diagonal matrices, and wavelets) are proposed, based on the analysis and estimation of power dissipation in the drivers. Power dissipation, supply voltage, number of time intervals required to address the display, and maximum number of voltage levels in the addressing waveforms of these techniques are compared with that of the Successive Approximation Technique.
