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)
