Abstract:
1. A plasma display apparatus, comprising: a plasma display panel including an address electrode; a control board that converts a video signal into a differential signal and transmits the differential signal, wherein the differential signal includes a first signal and a second signal being an inverted signal of the first signal and has a frequency of 200 MHz or more; and a data driver that receives the differential signal, restores the video signal from the differential signal, and supplies the restored video signal to the address electrode of the plasma display panel, wherein a voltage level difference between the first signal and the second signal substantially ranges from 0.1V to 0.5V, wherein: the control board includes or is coupled to a differential signal transmitter and the data driver includes or is coupled to a differential signal receiver, the differential signal transmitter transmits a main clock signal, a strobe signal, a high blanking signal, and a low blanking signal to the differential signal receiver, wherein the main clock signal, strobe signal, high blanking signal, and low blanking signal are transmitted in a transistor-transistor logic (TTL) manner, the differential signal receiver transmits the main clock signal, the strobe signal, the high blanking signal, and the low blanking signal to the data driver, the main clock signal is a clock signal for an operation of the data driver and has a frequency of substantially 50 MHz, the data driver is coupled to a data board, one or more transmission lines, formed on the data board, are coupled between the differential signal transmitter and the different signal receiver, and the differential signal includes a differential data signal which is subfield-mapped and rearranged for the address electrode and a differential clock signal for controlling transmission of the differential data signal.
