4. Function Specifications

4.1 Adjusting the Display Contrast

VDD

A Variable-Resistor must be connected to the

LCD module for providing a reference to V0.

Adjusting the VR will result the change of

LCD display contrast.

The recommended value of VR is 25k to 50k

VOUT

VSS

4.2 Resetting the LCD module

The LCD module should be initialized by hardware reset, using /RST terminal.

While turning on the VDD and VSS power supply, maintain /RST terminal at LOW level. After the

power supply stabilized, release the reset terminal (/RST=HIGH)
