Solomon Systech Ltd claims that its SSD2218 TFT driver controller, together with the SSD2802 Mobile Industry Processor Interface (MIPI) master bridge chip, is the world's first MIPI total solution for the display market.

SSD2218 is an all-in-one TFT LCD driver controller that integrates power circuits, a source driver and a gate driver, and a high-speed MIPI interface into a single chip. The SSD2218 can drive a 262K/16M color amorphous TFT (a-TFT) panel with a resolution of 240 RGB sources x 320 gates. The IC embeds a highly efficient DC/DC converter and a voltage regulator to generate all necessary voltage levels to the a-TFT panel with minimum external components.

In addition, the controller provides an 8-color power-saving mode to reduce the energy consumption in portable devices. The source and gate scan direction can be controlled by software commands. The SSD2218 supports the MIPI 18/24bit/pixel interface and contains two differential pairs for differential data transfer and differential clock, and also supports a 240 RGB x 320 x 18/24bit x 60Hz real-time display.

With an integrated MIPI interface, the number of signal connections between the host processor and the LCD driver is significantly reduced to only four wires. Not only will the solution save on interconnect costs, EMI and reliability, also enabling higher flexibility in the mechanical design of end products. The SSD2218 can work with MIPI-compliant processors and together with the SSD2802, non-MIPI processors can also take advantage of the MIPI interface.

Engineering samples of the SSD2218 and its supporting evaluation boards will be available in June 2007.
