BLOCK FUNCTION
1. Liquid-crystal drive circuit
This circuit selects and outputs the level for liquid-crystal driving.
One of V
DD
, V
EE
, and V1 is selected by the output of the selection control circuit.
2. Selection control circuit
This circuit creates the signal which will select the level of the output signal, based on the output of the shift
register circuit and the driving level power selection signals L1 and L2
3. Bidirectional shift register circuit
This refers to the 120-bit bidirectional shift register circuit. The DIR signal can be used to switch over the shift
direction.
The data that has been entered from the FRMB terminal is shifted by the row drive signal strobe (STB).
4. Level shifter circuit
This circuit transforms the 5-V signals to the high-voltage signals for liquid-crystal driving.
