HD66750/1
54
The HD66750/1 incorporates a voltage-follower operational amplifier for each of V1 to V5 to reduce
current flowing through the internal bleeder-resistors, which generate different liquid-crystal drive voltages.
Thus, potential difference between V
LCD
and V1 must be 0.1 V or higher, and that between V4 and GND
must be 1.4 V or higher. Note that the OPOFF pin must be grounded when using the operational amplifiers.
Place a capacitor of about 0.47
μ
F (B characteristics) between each internal operational amplifier (V1OUT
to V5OUT outputs) and GND and stabilize the output level of the operational amplifier. Adjust the
capacitance value of the stabilized capacitor after the LCD panel has been mounted and the screen quality
has been confirmed.
