of CL1. The grayscale-voltage selection circuits for high and low voltages are operated according to the M
signal level at the rise of CL1, and the grayscale voltages are output at the following rising edges of CL1.
To provide stable output operation of the buffer amplifier, the output is placed in the high-impedance state
in the high-level period of CL1.

Figure 6 Relationship between the M Signal and Data Input
Pin-by-Pin Inversion Drive
The HD66324T 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 HD66324Ts 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.
