The circuit drives the LED segment display indicating the floor number with various style requesting from the user. The circuit is also manufactured by the standard process. The circuit comprises an input processor (8) rectifying the signal detected from the position detector, a code generator (9) converting the detected signal to the corresponding floor number code, a timing clock generator (10) accessing the ROM data with the code and the clock pulse, and latches (U10-12) latching the display ROM data according to the combination of outputs of the generators (9,10).
