Printed transparent backplane for displays and spatial light modulators based on organic thin film transistors

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 and are transparent. The 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 this phase I program, we will demonstrate a new generation of transparent organic thin film transistors fabricated by our advanced inkjet printing method surpassing the requirements necessary for their use in high performance display driver circuits.
