Abstract
Methods, apparatus, and systems for generating drive sequences for pulse width modulated displays are described. A pulse width modulated signal that includes a drive sequence of temporal segments that are activated and deactivated to produce a desired gray scale. The temporal segments can be non-binary, non-equally weighted. The drive sequence can also include at least two of the temporal segments are least significant bit segments and the other segments are higher order segments.
