PURPOSE: A multi interface board for an LCD(Liquid Crystal Display) is provided to perform a signal connection with a connector having various pin types equipped to the main body of a system. CONSTITUTION: Input connector receiving members(21a,22a,23a) having other pin types are formed at each surface of a base substrate(50a). System main bodies(21,22,23) having various types of connectors(21b,22b,23b) are connected to the input connector receiving members(21a,22a,23a). A switching unit(52) electrically connects any one among the system main bodies(21,22,23) to a compensation circuit(51) selectively. The compensation circuit(51) performs an A/D conversion of the TTL level signal outputted from the switching unit(52) and simultaneously compensates an error according to the resistance value of each signal line for implementing an exact image.
