An apparatus and method for data interface of a flat panel display device, which is capable of transferring clocks in a state, in which the clocks are embedded in digital data, thereby reducing the number of transfer lines, is disclosed. The apparatus includes a transmitter unit built in a timing controller, to transmit transfer data with an embedding clock embedded between successive pieces of data, and a clock enable signal to indicate the embedding clock, and receiver units respectively built in a plurality of data integrated circuits connected to the timing controller, to separate and detect the embedding clock and the data from the transfer data, in response to the clock enable signal. 1. An apparatus for data interface of a flat panel display device comprising:a transmitter unit built in a timing controller, to transmit transfer data with an embedding clock embedded between successive pieces of data; andreceiver units respectively built in a plurality of data integrated circuits connected to the timing controller, to generate a clock mask signal, using the transfer data, and to separate and detect the embedding clock and the data from the transfer data, in response to the clock mask signalwherein the transmitter unit comprises:a frequency divider for frequency-dividing a dot clock, to supply the embedding clock;a serializer for converting pieces of input parallel data into pieces of serial data, embedding the embedding clock between successive ones of the serial data pieces, and supplying the resultant data as transfer data to be supplied to each of the data integrated circuits; anda differential signal transmitter for converting the transfer data into a differential signal, and transmitting the differential signal,wherein the receiver unit comprises:a differential signal receiver for recovering the transfer data, using the differential signal received from the transmitter unit;a clock/data detector for separating and detecting a first clock corresponding to ...
