The HD66717’s internal operational amplifiers have a reduced drive current to save current consumption;
when the internal operational amplifiers cannot fully drive the LCD panel used, an appropriate capacitors
must be inserted between each output of V1OUT to V5OUT and V
CC
to stabilize the operational amplifier
output (Figure 33). Especially, the capacitors for V1OUT and V4OUT must be inserted when 1/26 duty
or 1/34 duty drives.
