At ISAL last week, ams OSRAM introduced their new Aliyos™ technology: a thin, transparent, 2.5D-bendable foil for creating customized, multi-segment, adaptive, 3-dimensional lights and invisible-when-unlit lights on curved panels.
MiniLEDs are assembled onto a thin transparent substrate (the ‘foil’). Thin metal traces on top of the substrate are used for current-spreading within the segments, and as contact pads for the miniLEDs. Typically, several miniLEDs are connected in series within one string and several such strings, in turn, are connected in parallel to fill the segment area. The number and position of the LEDs and the corresponding wiring has a large degree of freedom, and so can be used to form individually-addressable segments of any shape. The flexible LED foils can be part of a transparent stack, or applied behind translucent materials.
