HD66773R
Interlaced Drive
The HD66773R supports interlaced drive, which divide one frame into n fields and then drive to prevent
flickers.
To determine the number of fields (n: value set in the FLD bits), check the display quality on the actual
liquid crystal panel. The following table shows the gate selection for each number of fields, 1 to 3. The
figure illustrates the output waveforms of the 3-field interlaced drive.
