Data interface device of display apparatus

A data interface device of a display apparatus, the data interface device comprising:

• a transfer device including an embedded encoder configured to encode a 10-bit original data packet as an 11-bit transfer data packet to transfer the 11-bit transfer data packet;
• and
• a reception device including an embedded decoder configured to the 11-bit transfer data packet, received from the transfer device through an interface circuit, as the 10-bit original data packet,
• wherein the embedded encoder sets a case delimiter in the 11-bit transfer data packet through bit extension from 10 bits to 11 bits and sets, to 5, a maximum run length representing a number of consecutive repetitions of 0 or 1 in at least one transfer data packet, and the embedded decoder decodes the 11-bit transfer data packet as the 10-bit original data packet with reference to the case delimiter.
