Passive and active materix liquid crystal displays with plastic substrates

摘要

Displays with plastic substrates are attractive since they are light, thin, virtually unbreakable and flexible e.g. for styling. Main applications are reflective displays for portable systems. Permetation of water and gases through plastics must be decreased by barrier layers; the thermal compaction is shunk by preannealing. a bistable freeroelectric display with plastic substrates is described; it exhibits an obliquely sputtered SiO_2-orientation layer leading to a large mechanical stability, which renders it suitable for smart cards and other portable s ystems. Low temperature PECVD-generated a-Si:TFTs are introduced and apprlied for the addressing of arrays of a-Si:H-TFTs are introduced and applied for the addressing of arrays of a-Si-light sensors. The overview is complemeted by bistable cholesteric dislays, MIM-addressed PDLC-displays, the first poly-Si-TFTs and finally solar cells and batteries with plastic substrates.
