Display, timing controller and column driver ic using clock embedded multi-level signaling

The present invention is an invention relating to a timing controller and column driver integrated circuits used by a display, a timing controller and column driver invention, in particular, multi-level of the clock signal by embedded signaling on the integrated circuit. The present invention is a receiving unit for receiving image data; Buffer output after temporarily storing the received image data memory; A timing control circuit for forming a transmission clock signal; And timing controller including the transmission data and a transmitter for receiving the transmission clock signal, said transmit clock signal transmitted on the signal is embedded in another signal level between the transmission data signal including the image data output from the buffer memory It provides. In addition to receiving the present invention after separating a clock signal embedded between received data signals using a magnitude of the received signal by sampling the received data signal using the separated reception clock signal output; A shift register and outputting the shifted start pulse in sequence; Depending on the signal output from the shift register, a data latch output in parallel after storing the image data included in the received data signals in sequence; And it provides a column driving integrated circuit comprising a DAC which converts the digital signal output from the data latch into an analog signal.
