4JET Technologies GmbH introduced a new laser process for customization and optimizing of organic LEDs at LOPE-C 2013. The new technology is a joint development with Novaled AG. The joint innovation is patent pending.

The innovation allows defined customization or grey scaling of encapsulated standard OLEDs. It also enables to optimize lighting density and is also suitable to isolate short circuits.

The new SLAM (Selective Layer Modification) process thus enables to create OLED signage solutions in lot size 1 and allows for individual logos or patterns. The use of ultra short laser pulses leaves no visible traces in the processed area when the OLED is turned off.

The flexible laser processing of the delicate films requires no lithography processes. For the first time, custom tailored signage applications can be created after manufacturing of the OLEDs.

The partners 4JET and Novaled will commercialize the SLAM process together. 4JET offers both fully integrated production systems, as well as job shop processing of OLEDs.
