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 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)

Note:

*1. This mono LCM is driven by a color LCD driver.

Every three dots are being driven by R G B segment driver.

*2. The above is based on:

- 4R4G4B setting, each dot will be driven by 4bit; LC[7:6]=0:1, DC[4]=1

- Mirror Y direction; LC[2]=0

- Normal X direction; LC[1]=1

- Color Mapping as BGR; LC[5]=0
