How it works
In the scientific community, our liquid light concept is known as the Light-Emitting Electrochemical Cell (LEC). From a distance and a layman’s perspective, this technology is very similar to the Organic Light-Emitting Diode (OLED), as both technologies use a flat planar structure in which the light-emitting organic layer is sandwiched between two conductive electrodes.
The major production advantages with LECs are:
–Ambient conditions, i.e. no clean room, no vacuum required, regular lab environment with vent hood sufficient
–Only three layers, i.e. two electrodes with one active layer in between, that’s it
–All layers from solutions, i.e. the foundation for roll-2-roll production is demonstrated
–Simple equipment, it is possible to create your own LECs with an airbrush from Hobby Lobby, and an office laminator
The initial LEC applications are in “disposable” applications, where the environmental footprint and ease of fabrication has a large impact on overall life cycle management. The LEC is suitable for low-information content, where the entire pixel is patterned with a static color or pattern.
