DISPLAY DRIVING SYSTEM USING TRANSMISSION OF SINGLE-LEVEL SIGNAL EMBEDDED WITH CLOCK SIGNAL

摘要

The present invention relates to a display driving system, more specifically to the display driving system using single-level signal transmission which adopts a data transmission method using an embedded clock signal. The display driving system comprises: a timing control unit that embeds a same level clock signal in a data signal and transmits the data signal to a panel driving unit; and a panel driving unit that restores the embedded clock signal from the transmitted data signal, then outputs image data by sampling data based on the clock signal stabilized during a clock training period. Therefore, the display driving system not only can maximize the data transmission speed, but also can minimize the level of a transmission signal and the frequency of the embedded clock signal. In addition, the display driving system is able to minimize an impedance mismatch and EMI (Electro-Magnetic Interference).
