TC3410-AS is an integrated Multi-touch Controller and eDP Timing Controller embedded driver (tTED) for in-cell TFT 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.

TC3410-AS supports 4 lanes eDP1.5 input up to 5.4G bit rate and 1926 channels source driver output.

TC3410-AS implements eDP1.5 Multi-Stream Operation (MSO) for two chip display synchronization. The touch control and processing synchronization is excecuted by SPI interface.

TC3410-AS is designed for COG (Chip on Glass) assembly.
