Abstract
Recent materials development together with an improving understanding of organic transistors has enabled solution-processed materials that show good performance, with high transparency in the visible range. In this program, leveraging on our extensive experience in organic material development and large scale organic material deposition by solution based processing, Agiltron and Stanford University propose to realize the first transparent backplane based on organic thin film transistor to drive displays and spatial light modulators. The organic semiconductor materials proposed have high field effect mobility, good solubility, good film formation capability, and are transparent. A transparent cross-linked dielectric layer ensures low leakage current and enables multiple layer structures to be created by solution based processing. Furthermore, our optimized device design and fabrication process can maximize the performance of the organic semiconductor through the matching of organic semiconductors and dielectric materials. In Phase I we have demonstrated a new generation of transparent organic thin film transistors fabricated by our advanced printing method surpassing the requirements necessary for their use in display driver circuits. During Phase II, we will further improve the device performance and fabricate the transparent backplane by printing for transparent active matrix organic light emitting diodes display.
