A low-power two-line inversion method for driving LCD panels

摘要

A new two-line based inversion driving method is introduced for low-power consumption of display driver ICs. Eliminating the correlation between the chopper stabilization and the polarity of LCD, we can reduce power consumption without noticeable degradation of display quality. Applying the proposed scheme to 17″ LCD applications, we achieved 12% power saving in DDI with white patterns and 27% with black patterns.
