Note 2. All voltages measured to GND (Pin4).
Note 3. Typical range is 1 to 6V, the range can be increased (e.g. 0 to 7V) to slightly increase the
control range.
Note 4. Open contrast control pin leads to undefined contrast setting.
Note 5. The internal reference voltage can be measured at Pin18, Pin15, and Pin12 during output
clamping in closed feedback loop.
Note 6. Minimum guaranteed control range, the typical minimum black level voltage is 0.1V.
