FD Signal
The FD signal is the field determination signal; a field is determined by the state of this signal at the
rising edge of the OE signal. This signal synchronizes the internal controllers with TV signals.
The order of outputting signals is determined at the fourth rising edge of the OE signal after the rising or
falling edge of the FD signal in double-rate sequential drive mode, while it is determined at the third
rising edge in single-rate sequential drive mode; herein after, as long as the FD signal is not changed,
signals will be output in the determined order at most every 12 pulses of the OE signal in double-rate
sequential drive mode, while at most every 6 pulses in single-rate sequential drive mode.
The FD signal should usually be high in the first field and low in the second field. In some modes,
however, it should be high in both fields, but low for at least one-pulse time period of the OE signal
during the horizontal scanning period.
The order of outputting signals and the timing of inputting the FD signal vary depending on the mode.
For more details, refer to the appropriate timing charts.
