Patent ID: 8279216

Claim:
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; and receiver 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 signal wherein 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; and a 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 the embedding clock and the serial data from the transfer data, in response to the clock mask signal; a frequency multiplier for multiplying a frequency of the first clock, to output a second clock; a deserializer for converting the serial data into parallel data, using the second clock, and outputting the parallel data; and a mask signal generator for generating the clock mask signal, using the first and second clocks.
