The TC3406 is an integrated Multi‐touch Controller and eDP Timing Controller embedded driver (tTED) for in‐cell a‐Si TFT HD panel that incorporates gate drivers in panel (GIP) and source de‐multiplexers. It provides the GIP control high voltage signals with embedded level shifters. The gamma correction circuit allows adjustment to panel characteristics to optimize the display quality.

TC3406 supports 1 lane eDP1.4b input with HBR, R243, R216 and RBR bit rate and 2052 channels source driver output.

TC3406 is designed for COG (Chip on Glass) assembly.
