TC2079 is a 1446-channel source driver for high resolution TFT LCD. It is designed for COG (Chip-on-glass) application. The input interface is SIPI™ (Scalable Intra Panel Interface) which has been developed and patented by Parade Technologies. SIPI™ is a point-to-point interface between Timing Controller (TCON) and Source Driver (SD). The SIPI™ intra panel interface provides scalable bandwidth with reduced bus width, low EMI and low power, more robust protocol to establish link and enhance system reliability to address existing and future growth of high resolution digital display on notebook and tablet PCs and other consumer electronics applications.

On output side, TC2079 converts 8-bit (RGB888) digital data into 256 gray scale analog voltage for each channel; charging each dot (sub-pixel) to the correct gray level. It also supports 12 reference voltages for Gamma correction.
