Pin-by-pin Inversion Drive
With regard to the inversion standard voltage for individual adjacent odd and even output pins, the
HD66350T can generate 256-level positive-polarity and negative-polarity grayscale voltages. In
addition, the liquid-crystal alternating-current drive can be controlled by switching the polarity of the
M signal. (See the Pin Functions section.)
In this way, when HD66350Ts are arranged on either the upper or lower side of a TFT LCD panel, a
dot inversion drive can be used in which grayscale voltages of different polarities are applied to
individual adjacent dots by switching the M signal on each CL1 clock, reducing the crosstalk which
adversely affects image quality, and thus achieving a high-quality display.

Figure 7 Dot Inversion Drive
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.
