Defect analysis of roll-to-roll SAIL manufactured flexible display backplanes

HP and Phicot have made the worlds first roll-to-roll (R2R) manufactured active matrix displays. Currently we are developing a wrist-worn solar powered display for the U.S. Army. As we scale from research to preproduction on our 1/3 meter wide pilot line defect analysis and mitigation is our primary focus. In this presentation we will review the self-aligned imprint lithography (SAIL) process and discuss defects we observe, and the tools, and processes we have developed to detect and eliminate them

29.1: Invited Paper: Electrical Testing of Roll-to-Roll SAIL Manufactured Flexible Display Backplanes

HP and Phicot are making a fully roll-to roll fabricated display for a solar powered wrist display. We have developed methods for electrical testing of display backplanes on flexible substrates which are not bonded to a carrier. This has enabled improvement of yield through rapid electrical test feedback.

Desktop binding: A novel approach to booklet making hardware

A low cost method and device for creating saddle stitch bound booklet documents is described. The device allows saddle stitch bound documents to be made using a unique low force method that avoids the issues and limitations found in commercial booklet making hardware. Typical commercial devices use high force industrial equipment that are physically bulky, unsafe, and expensive. The approach detailed here utilizes precision, light force, sheet-wise operations on individual sheets of paper to produce saddle stitch booklets, leveraging knowledge in precision paper handling and positioning. This method facilitates bound document creation with hardware that is compatible with common desktop and workgroup printers sheet-at-a-time printing processes, but at a fraction of the cost of comparable commercial binding hardware. This platform enables the final part of the promise of desktop publishing.
