Notes:
1) CONTRAST data
The CONTRAST data is adjustable, and used as reference data for other adjustment items, which is not
memorized in the EEPROM.
2) BRIGHT and COM AMP data
The BRIGHT and COM AMP adjustments are made by using the same 2-screen IC register(SA22h B7-2: common
reverse output amplitude).
Therefore, adjusting one of the data will change the other one.

1) CONTRAST data
The CONTRAST data is adjustable, and used as reference data for other adjustment items, which is not
memorized in the EEPROM.
2) SUB BRI R and SUB BRI B data
The displayed value or EEPROM written data is different from the setting value for the 2-screen IC register
(IC4001 : TC90A64AF-P).
(Before displayed on the screen, the setting value is converted via some software.)
