Decoder
Generates a 64-level gray scale voltage based on the LCD drive voltage (V8–V0) and selects the LCD
applicable voltage using the 6-bit data decoded signal.
6. Output amplifier
Alternately inverts the LCD applicable voltage to negative and positive polarities with respect to the
inversion reference voltage (VCEN) and outputs them synchronously with the AC signal (M signal).
