44.2: <i>Invited Paper:</i> Printed Polymer TFTs Towards Low-Cost Backplane Production

摘要： We present Merck’s new formulation and material developments enabling high-volume and high-throughput printing techniques to be used for cost-effective electronic circuitry and backplane production. Performance at TFT array level in excess of 2 cm2/Vs, comparable to spin coating is demonstrated at Gen1 scale and 50 ppi resolution, using a hybrid combination of conventional lithographic steps and direct gravure printing.
