Abstract: PROBLEM TO BE SOLVED: To make the constitution simpler and small-sized by putting a power supply line for supplying the electric power to a display part and a supply line for supplying image data together into one transmission line. SOLUTION: The computer device 1 supplies a source voltage of +12 V, digital image data S95A, an audio signal S97, and a lamp driving signal S95B from a main body part 2 to a liquid crystal display 6 through a display cable 5. Consequently, the main body part 2 and liquid crystal display 6 can be connected by one cable and then the power cable and video cable are never entwined to make the constitution simple. Further, a power supply means such as a power unit need not be provided in the display 6 and then the liquid crystal display 6 is therefore made thin and small-sized on the whole. Further, the digital image data S95A are sent out to the liquid crystal display 6 to eliminate the need for a process for A/D conversion, thereby simplifying the circuit constitution.
