1932 channel source driver for TFT COF LCD panels

TC2101 is a 1932/1812/1740/1632/1512/1452/1284/1092-channel source driver for high resolution TFT LCD panels. It is designed for COF (Chip-on-film) application. The input interface is SIPI™ (Scalable Intra Panel Interface) which was developed and patented by Parade Technologies. SIPI is a high speed, point-to-point interface between the Timing Controller (TCON) and Source Driver (SD), including the TC2101. The SIPI intra panel interface provides scalable bandwidth with reduced bus width, low EMI, low power, a more robust protocol to establish the high-speed link, and enhance system reliability. SIPI was developed to address the newer demands created by increased display performance on notebook and tablet PCs and other consumer electronics applications.

On the output side, the TC2101 converts 8-bit (RGB888) digital data into a 256-level gray scale analog voltage for each sub-pixel channel, charging each sub-pixel to the correct gray level. It also supports up to 14 reference voltages for Gamma correction.
