Issues with Non-Lithographic Production of Displays

Presented by Jeff Meth, Dupont

Alternate imaging technologies may potentially improve many display products. Thin film transfer (TFT) arrays and color filters (CF) are two applications that have received attention over the last decade. I will describe patterned chemical bath deposition of CdS combined with laminated polymer dielectrics to exemplify the issues surrounding the manufacture of TFT arrays. Specific interactions will be addressed in pentacenestyrenic polymer examples. In addition, this talk will describe physical modeling of laser-induced imaging for making color filters: heat flow in thin films on a microsecond time scale; mechanical effects for writing patterns; and contact mechanics of thin viscoelastic films. Finally, I hope to communicate, through these examples, how to work effectively in an industrial research environment.
