Pin-by-Pin Inversion Drive
The HD66325A can generate 64-level positive-polarity and negative-polarity grayscale voltages with
respect to the inverted reference voltage for individual adjacent odd and even output pins. In addition,
the liquid-crystal alternate current drive can be controlled by switching the polarity of the M signal.
(See the Pin Functions section.)
In this way, when HD66325As are arranged on either the upper or lower side of a TFT LCD panel, a
dot inversion drive can be performed in which grayscale voltages of different polarity are applied to
individual adjacent dots by switching the M signal on each CL1 clock, reducing the crosstalk which
adversely affects image quality, and so achieving a high-quality display.

When the M signal switches on each CL1n clock, the following n-raster-row inversion drive can be
used on each horizontal dot and vertical n-raster-row.
