⢠Common output pins not used because of the duty cycle can be used for common double-
buffering (parallel connection).
⢠Display possible in operating modes other than standby mode
⢠Choice of 11 frame frequencies
⢠Built-in power supply split-resistance, supplying LCD drive power
⢠Use of module standby mode enables this module to be placed in standby mode independently
when not used.
