128 x 128, 16 Gray Scale Dot Matrix

OLED/PLED Segment/Common Driver with Controller



SSD1327 is a single-chip CMOS OLED/PLED driver with controller for organic/polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 128 commons. This IC is designed for Common Cathode type OLED/PLED panel.

SSD1327 displays data directly from its internal 128 x 128 x 4 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from general MCU through the hardware selectable I2C Interface, 6800-/8080-series compatible Parallel Interface or Serial Peripheral Interface.

  • Resolution: 128 x 128 matrix panel
  • Power supply

– VCC= 8V – 18V       (Panel driving power supply)

– VCI= 1.65V – 3.5V   (MCU interface logic level & low voltage power supply)

– VDD= 1.65V – 2.6V  (Core VDD power supply, details refer to Table 2-1)


Table 2-1 VCI and VDD range


VCI VDD Remarks
1.65 V ~ 2.6V 1.65V ~ 2.6V VDD should be tied to VCI and supplied by external power source
2.6V ~ 3.5V 2.4V ~ 2.6V VDD is regulated from VCI
