solid state lighting

Epigem’s Epimesh film replaces the transparent conducting layer used in current organic lighting panels with a grid-like network of vanishingly small metal wires in combination with a very thin organic conductor. The film is about 10 times more conducting than ITO for the same transmission, enabling much larger area lighting panels with good uniformity of brightness from centre to edge. To achieve the same performance, current large area lighting panels require additional metallic busbars to be fabricated onto the ITO layer. This is costly and adds extra processing steps, increasing the chance of device failure. The Epimesh film acts as both ITO and busbar in one, thus giving much reduced production cost and complexity..
