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)
