Liquid Crystal Display Voltage Generator
When External Power Supply and Internal Operational Amplifiers are Used
To supply LCD drive voltage directly from the external power supply without using the internal booster,
circuits should be connected as shown in figure 36. Here, contrast can be adjusted by software through the
CT bits of the contrast adjustment register.
The HD66732 incorporates a voltage-follower operational amplifier for each V1 to V5 to reduce current
flowing through the internal bleeder-resistors, which generate different levels of liquid-crystal drive
voltages. Thus, the potential difference between V
LCD
and V1 must be 0.1 V or higher, and ones between
V4 and GND between V2 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 0.1
μ
F to 0.5
μ
F between each internal
operational amplifier V1OUT to V5OUT output and GND and stabilize the output level of the operational
amplifier.
