Block Functions
LCD Drive Circuit
The 120-bit LCD drive circuit generates four voltage levels V1, V2, V5, and V6, which drive the LCD
panel. One of these four levels is output to the corresponding X pin, depending on the combination of the
M signal and the data in the shift register.
Level Shifter
The level shifter changes logic control signals (2.5 V–5.5 V) into high-voltage signals for the LCD drive
circuit.
Shift Register
The 120-bit shift register shifts the data input via the DIO pin by one bit at a time. The one bit of shifted-
out data is output from the DIO pin to the next driver IC. Both actions occur simultaneously at the falling
edge of each shift clock (CL) pulse. The SHL pin selects the data shift direction.
