M Signal and Data Input
This example shows the relationship between the data input, M signal, and output level, with dot-by-
dot inversion and frame inversion. The HD66325A driver must hold the M signal during the high-level
period 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 falling 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.
