VTT Developing 3D LED Advertisement Boards
VTT is developing unique LED advertising displays which combine thin, lightweight and bendable structures with advanced optical quality. The technique will result in an LED display which will let the users have a 3D viewing experience without them wearing glasses designed for the purpose.
The European project named OptIntegral, launched in start of January, uses a manufacturing process based on in-mould hybrid integration of TOLAE (Thin, Organic and Large Area Electronics) and photonics components. This enables manufacturing of LED displays at a lower cost and much higher display resolution.
The optics are moulded directly upon a bendable LED substrate, during an injection moulding process. This makes the displays energy-efficient, extremely lightweight, bendable and 3D. This technique will be implemented during the planned three years of the project, and will be integrated in creating bendable illuminated advertisement boards, suitable for applications like transport and others which require 3D designs and less weight.
The VTT Technical Research Centre of Finland Ltd is supervising and developing the bendable LED substrates for displays with a roll-to-roll manufacturing process, integrating the in-mould hybrid technology.
Apart from VTT, Neonelektro Oy is another Finnish participant in the project.
The project is coordinated by Fundació Privada Ascamm ( ASCAMM) and the consortium consists of SimulacionsOptiques SL ( Snell) and Asociación Española de Normalización y Certificación ( AENOR) from Spain , LumyComp design and Megatex Commerce Ltd from Bulgaria , Holografika Hologramelőállító FEJLESZTO és Forgalmazó Kft . fromHungary and University of Bath from the UK.
