Cross pairing of select and data voltages to display grayscales in liquid crystal displays
No full textRestricted Access.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 voltage
