The 3D OLEDs used in the rear
lights of the Audi TT were produced
by Philips. For this purpose, the OLED
manufacturing process which was
previously based on 2D glass substrates
had to be adapted to the third dimen-
sion. This related not only to the
processes and technologies for manufac-
turing the glass substrates themselves,
but also to vacuum-based OLED coating,
encapsulation, and electrical contacting.
