Abstract
Successive approximation technique (SAT) has select voltages
of row waveforms paired up with data voltages of column waveforms to achieve
the maximum selection ratio. Cross pairing of select and data voltages without
compromising the selection ratio generates more rms voltages as compared to
SAT. Grayscales can be displayed with less number of voltages in the addressing
waveforms and less number of time intervals in a cycle as compared to SAT
by cross pairing of select voltages with data voltages. Better brightness
uniformity among pixels that are driven to same grayscale can be achieved
by cross pairing because the width of the select pulses increases due to less
number of time intervals in a cycle as compared to SAT. About 50% reduction
in number voltages in row waveforms and column waveforms in addition to a
50% reduction in number of time intervals in a cycle can be achieved as compared
to SAT by cross pairing select and data voltages.
