Laser micromachining of organic LEDs

OLED lighting is expected to be one of the fastest growing markets in the area of organic electronics. The state of the art production is mainly based on vacuum deposition processes, which, in order to simplify the material handling, will most probably be embedded in a roll-to-roll environment. While reducing the handling costs also implies challenges to the patterning of the several OLED layers. Laser micromachining applying ultra-short pulsed laser sources has the potential to fully satisfy the requirements. Within this paper the latest findings on the separate scribing steps P1, P2 and P3 will be presented.
