A Flexible electronic‐paper display with an ultra‐thin and flexible LSI driver using quick‐response liquid‐powder technology

— A thin and flexible LSI driver with a thickness of less than 35 μm for a passive-matrix-driven Quick-Response Liquid-Powder Display (QR-LPD™) was successfully mounted onto the flexible printed circuit (FPC) and the back substrates of a flexible QR-LPD™. Amounted LSI driver on a plastic substrate shows no significant degradation in the driving performances and maintains physical flexibility without any connection failures. This technology can realize a fully flexible electronic paper in combination with a plastic-substrate QR-LPD™ fabricated by a roll-to-roll process.
