Relationship Between LCD Screen Size and Display RAM
This LCD driver has built-in RAM for the display of 16 x 64 = 1024 bits and each address
corresponds to each 1/16 duty of the LCD.
The data corresponds to the number of dots in the X direction. The relation between the LCD
screen size and the display RAM is shown below.
