4. Function Specifications

4.1 Adjusting the Display Contrast

- This LCD module equipped with latest digital contrast adjustment function.

- Its display contrast could be adjusted by MCU command. (please see the command tables for

details)

- It is recommended to provide a contrast adjustment interface for end-user, where the best

display result could meet the individual preference in mass production.

4.2 Application circuit (Example)

NOTE: 8080 mode (Default setting), please refer to UC1611 datasheet for details.

4.3 Resetting the LCD module

The LCD module should be initialized by 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)
