The present invention relates to a display, a timing controller and a column driver IC, and more particularly to a display, timing controller and column driver integrated circuit using clock embedded multi-level signaling. The present invention provides a timing controller including a transmitter for transmitting a transmission signal wherein a transmission clock signal is embedded therein between a transmission data signal to have a signal magnitude different from that of the transmission data signal. The present invention also provides a column driver integrated circuit including a receiving unit for separating a clock signal from a received signal using a magnitude of the received signal, and for performing a sampling of a received data signal from the received signal using the separated clock signal.
