Abstract

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.

Description

technical field [0001] The present invention relates to a display, a timing controller, and a column driver IC (integrated circuit), and more particularly, to a display, a timing controller, and a column driver IC using a clock to embed multilevel signals. Background technique [0002] Recently, in addition to the increasing popularity of portable electronic devices such as notebook computers and personal portable communication devices, the market size of digital electric appliances and personal computers is also increasing. A display device, which is a final connection medium between such a device and a user, is required to have light weight and low power consumption. Therefore, FPDs (Flat Panel Displays) such as LCDs (Liquid Crystal Displays), PDPs (Plasma Display Panels), and OLEDs (Organic Electroluminescent Displays) are generally used instead of conventional CRTs (Cathode Ray Tubes). [0003] As described above, for a general FPD system, a timing controller and a driv...
