LCD Segment / Common COLOR Driver with Controller

SSD1788 is a single-chip CMOS color STN LCD driver with controller for dot-matrix graphic liquid crystal display system. SSD1788 consists of 362 high voltage driving output pins for driving maximum 98 RGB Segments and 68 Commons.

SSD1788 consists of 294 (98 RGB) x 68 x 4 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from common MCU through 8-bit 6800-series / 8080-series compatible Parallel Interface or 3-wires / 4-wires Serial Peripheral Interface by pins selection.

SSD1788 embeds DC-DC Converter, On-Chip Oscillator and Bias Divider so as to reduce the number of external components. With the advanced design, low power consumption, stable LCD operating voltage and flexible die package layout, SSD1788 is suitable for any portable battery-driven applications requiring long operation period with compact size.
