Novaled and 4JET Technologies has jointly developed a new laser process called SLAM (Selective Layer Modification) for OLED customization and optimization. SLAM allows defined customization or grey scaling and it can also be used to optimize lighting density and to isolate short circuits.
4JET says that SLAM can be used to create OLED signage solutions with individual logos or patterns. Basically this creates structured OLEDs (like we've seen from Philips, Fraunhofer, UDC and others) after the manufacturing process.
4JET says that SLAM uses ultra-short laser pulses and it leaves no visible traces in the processed area when the OLED is turned off. The process does not require any lithography process. 4JET and Novaled will jointly commercialize the SLAM process, which is patent pending.
