54.2: Thin Plastic Electrophoretic Displays Fabricated by a Novel Process

Abstract

We have developed a new way of making flexible, plastic active matrix displays using standard amorphous silicon TFT fabrication facilities. Using this technique we have made electrophoretic displays with three micron thick plastic a-Si TFT backpanes. We believe that these are the thinnest plastic displays ever made.

Polysilicon thin-film transistors on polymer substrates

“…The process was inspired to the a-Si TFTs fabrication method on polyimide layer proposed by Philips Res. Lab [50], called Electronics on Plastic by Laser Release (EPLaR). In the EPLaR process, PI is spin-coated onto glass or quartz substrates and laser released after device fabrication, by irradiating the PI through the substrate.…”

“…However, it's brown color and has low light transmission over the range of visible light. Therefore, the application of Kapton will be limited only in self-emitting or reflective-type displays [2]. It is a critical issue to fabricate the flexible electronics about handling the flexible substrate during TFT processes.…”

10.2: Invited Paper: Flexible E‐Books

“…The EPLaR process for making flexible EPDs uses more than 95% of the same process steps and equipment that are used for making glass EPDs [8]. We will first describe the process on glass and then explain how it has been adapted for EPLaR.…”
