FUNCTION DESCRIPTION
(1) Shift Resister
205 bits resister
(2) Latch Circuit
Data stored in display data register is assigned to the corresponding SEG.
(3) Segment Driver
Basing on display data, segment drivers output LCD SEG driving signal.
(4) Common Driver
Common drivers output LCD COM driving signal.
(5) Voltage converter/ Regulator
The voltage input to the VCI terminal is boost 2-times(VCI x 2). Please set the input so that the output should
not exceed 12V. When you can contrast adjustment, V0 voltage can be decided by adjusting VREF
voltage.When Internal booster circuit is not used, should be C1N, C1P open and should be VCI, VREF keep
GND.
