Dot Matrix Driver/Controller IC


PT6891

The PT6891 is a single-chip CMOS OLED driver for O/PLED (organic/polymer light emitting diode) passive dot matrix graphic display systems. The PT6891 consists of 96 cathodes (commons) and 128 anodes (segments).

The PT6891 displays data directly from its internal 128x32x3x6 (128x32 RGB dots) GD-RAM (Graphic Data RAM) or 128x96x6 (128x32 Mono dots) GD-RAM (Graphic Data RAM). Data/Commands are sent from the general MCU through parallel interface or serial interface.

The PT6891 reduces the number of external components by including a brightness control function and an on-chip oscillator.
