Internal Block Diagram
1. LCD drive circuit
This circuit selects and outputs the three level signals for the LCD drive. By a combination of the
data in the shift register and M, either VH, VL, or VM is selected and transmitted to the output
circuit.
2. Level shifter
This boosts a 5-V signal to a high-voltage signal for LCD drive.
3. Shift register
This is a 240-bit bidirectional shift register circuit. The first line marker signal output from the DIO1
pin and DIO2 pin is sequentially shifted by shift clock CL. The shift direction is determined by the
SHL pin.
4. Alternating signal generating circuit
This circuit generates an alternating signal (M signal) for LCD display. To suppress cross-talk, the
signal is alternated in a unit from several lines to several tens of lines. By connecting MWS0 to
MWS4 pins to Vcc or GND, the desired number of signals can be alternated. When alternating
signals are externally input, all pins (MWS0 to MWS4) are connected to GND.
