Abstract:
1. A liquid crystal display device comprising: a liquid crystal display panel on which a plurality of data lines cross a plurality of gate lines, wherein each data line and each gate line is connected to a thin film transistor; a source drive IC that supplies data voltages to the data lines; a gate drive IC that supplies gate pulses to the gate lines; a system board equipped with a scaler that transmits data from the scaler with a first interface specification; an interface board that receives the data according to the first interface specification, and transmitting the data with a second interface specification; and a control board equipped with a timing controller receiving the data in the second interface specification and supplying the data to the source drive IC, and controlling the operating timing of the source drive IC and the gate drive IC; wherein the interface board is connected between the system board and the control board, the interface board includes: wherein a number of the data transmitting lines required in the second interface specification is less than a number of data transmitting line required in the first interface specification.
