Liquid crystal displays could soon be painted on to surfaces, using a technique currently being refined by researchers at Philips laboratories in the Netherlands.

The process removes the need to sandwich liquid crystals between two layers of plastic or glass. Instead, a liquid crystal mixture is painted directly onto a surface and then treated with ultraviolet light.

The technique could potentially allow manufacturers to make displays more quickly because the liquid crystal mixtures do not have to be carefully poured between two surfaces.
