5. Function specifications

5.1 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.

5.2 Basic Setting

To drive the LCD module correctly and provide normally display, please use the following setting

- ADC = 1 (reverse)

- SHL select = 0 (normal)

- LCD Bias Select = 1/9

- Initial Display Line = 0

- Entire Display ON/OFF = OFF (normal)

- Reverse Display ON/OFF = OFF (normal)

- Set Power Control Set:

voltage follower = ON, voltage converter = ON, voltage regulator = ON

- Built-in OSC = ON

- Display ON/OFF = ON

Note:

*1. These setting/commands should issue the LCD module while start up.

*2. See the Display Commands section for details.

5.3 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)
