Abstract

We developed liquid luminescent flexible displays using electrochemiluminescent solution as deformable luminescent material. The solution consisted of ruthenium complexes as light emitting material and ionic liquid as nonvolatile solvent. We injected the solution, to pattern and seal it, into microfluidic cells between two flexible films of polyethylene terephthalate substrates with indium tin oxide electrodes. The light emitting area of one cell was 2×2 mm 2 The gap between the electrodes was 100 μm. We measured the luminance of the cell during application of 5OHz/4.OVpp (peak-to-peak value) rectangular waves of voltage in bent condition. The device was bent along the convex curvature with radii of 60, 30 and 20 mm. The luminance was reduced by only 30 00 when the radius of curvature reached 20 mm. We conclude the electrochemiluminescent cells are suitable for flexible displays because they can tolerate large deformation of bending.
