    (54) Interface, for example for a liquid crystal display device


    (57) An interface for converting separate video signals into a display data signal and a timing signal for operating a thin display panel comprises a timing circuit (101, 102, 103) for taking a timing so as to introduce effective display data into a data treating circuit (105) according to a synchronizing signal (Hsyc), a data treating circuit (105) for generating desired data for a thin display panel using the display data, and a timing signal generating circuit (104) for generating timing signals necessary for operating a driver of the thin display panel.
