Functional Electronic Screen-printing – Electroluminescent Lamps on Fabric

AbstractA planar electroluminescent (EL) lamp has been screen-printed directly on to woven polyester cotton fabric to create a smart fabric lamp. The EL lamp consists of six printed layers and has been produced in colours: light blue, dark blue, and orange. The printed structure has high durability whilst maintaining the flexible and breathable properties of the fabric. The printing process relies on an interface layer developed at the University of Southampton [1] to smooth the woven fabric surface where required, presenting a more homogenous surface than the underlying woven fabric for the subsequently printed functional layers
