An interface system and a flat panel display using the same are provided to transmit information corresponding to two bits at once between a transmitting circuit disposed in an external system and a receiving circuit disposed in a panel, thereby lowering a clock frequency. A serializer(202) receives first and second data having plural bits from the outside, and sequentially outputs the bits of the received first and second data. A transmitting circuit(204) generates four voltage levels in correspondence with two bits supplied from the serializer. A receiving circuit(212) restores the two bits by using the voltage level supplied from the transmitting circuit. A deserializer restores the first and second data as sequentially storing the two bits supplied from the receiving circuit. The serializer includes first and second serializing units for sequentially outputting bits of the first and second data.
