TC1312V is a highly integrated LVDS touch with tcon embedded source drivers for automotive cockpit displays. The device supports displays up to 35” at 7680RGB*1260 in a multi-chip cascade configuration. On-chip support for TPMUX allows single-chip operation with excellent touch performacne up to 15.6” screen size. Its pinout is compatible with the most common footprint in the industry, greatly increasing its ease of adoption. In addition to excellent touch performance backed by Parade’s TrueTouch™ patented technology portfolio, TC1312V supports the required silicon features to minimize EMI and achieve CISPR-25 requirements for the in-cell display module. TC1312V’s unique touch sensing technology will allow us to keep touch refresh rate high and responsible while at the same time supporting Variable Refresh Rate (VRR) technology.
