At its booth, Osram demonstrated how the combination of OLED with LEDs opens up a wide range of design options for rear lights. The LED/OLED rear light demonstrator, which showcases four lighting functions – brake light, turn indicator, reversing light and rear light, uses two different types of round OLED tiles but for it to work as a rear light, red OLEDs light up in a concentric double-ring structure, with each ring being individually addressable. Wide luminous mono rings of yellow OLEDs make up the turn indicator. The center of the OLED rings is transparent. Six white power LEDs shine through the transparent area of the yellow indicator OLEDs – for the reversing Similarly, red power LEDs shine through the transparent centers of the red OLEDs, making up the brake light. On top of that, the demonstrator will display LED light guide solutions which support both brake light and turn indicator functionality.
