(a) Photograph of the patterned emission from an 8 × 8 mm2 line-art bilayer LEC device. The ‘fish’ pattern was created by ‘drawing’ in the electrolyte layer with a syringe needle, as schematically shown in the upper right inset. (b) Photograph of a showcase setup indicating the broad range of emission colors and patterns available with the line-art technology. The dashed lines indicate the substrate edges, where the electrode contact points are located. All devices were driven by a constant voltage of 4 V.
