A device for controlling ISG logic is mounted in a vehicle equipped with an ISG system. The layers include electrodes of which at least one electrode is transparent and one acts as an anode and one as a cathode, and at least one organic electroluminescent layer that is arranged between the electrodes. The organic light-emitting area is disposed over the first surface of the transparent substrate and comprises a plurality of pixels for emitting white light or short-wavelength light. The computer produces prints in the same manner as when directly reading the image data from the memory card.
