wavelength region 540 nm and 2 4 at the red wavelength region 620 nm in an advantageous embodiment of the inventive device for example stripes of red oleds having a rc2 structure can be combined with stripes of green oleds having a rc2 structure and with stripes of blue oleds having an rc2 structure the stripes of blue oleds may instead of the rc2 structure being combined with an efficient out coupling mechanism for example by use of micro lenses and a carrier substrate with an optically thick high index substrate layer n 1 75 u2212 1 85 of a thickness of some 10 u03bcm between the anode of e g ito and the substrate of float glass such a high index interlayer between the oled and the carrier substrate can also be provided together with the rc2 structures and then is arranged between the carrier substrate and the second layer structure fig3 shows a schematic arrangement of the oled stripes of an exemplary embodiment of the present device in this case the different stripes of the oleds of different colors have the same widths which is however not mandatory the widths of the oleds of different colors may also be different accounting for the different emission efficacy in order to achieve white light the figure shows seven groups of oleds each group been formed of a red oled 15 a green oled 16 and a blue oled 17 such a device has typical dimensions of a height h and width w of 32 u00d7 34 mm 2 or 50 u00d7 50 mm 2 the fill factor is between 80 and.
