Technologies toward flexible liquid-crystal displays

Abstract

Abstract— Several leading technologies for flexible liquid‐crystal displays have been developed recently at ERSO. The roll‐to‐roll compatible techniques, polymer‐added liquid crystal, have been applied on a film‐like substrate. A flexible black‐and‐white cholesteric liquid‐crystal display was also implemented by photo‐induced phase separation. Color filters placed on a plastic substrate by a low‐temperature manufacturing process was successfully fabricated. A novel design of a wide‐viewing‐angle color plastic LCD was also proposed.

“…Motivated by these advantages, many researchers, mainly in industries, are intensively researching flexible displays for practical applications. [70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86] Display elements include organic LED and electrophoretic devices, which can exhibit flexibility through control by TFT drive circuits fabricated on plastic films. Thus far, many flexible displays and electronic papers with excellent definition, luminescence, and other characteristics have been reported.…”

“…ecently, much research has focused on flexible displays because of their favorable characteristics, including light weight, thinness, and flexibility. [1][2][3][4][5] Therefore, flexible displays have potential use in mobile phones, smart cards, e-paper, and other handheld products. Numerous display technologies, including organic lightemitting displays [6][7][8] (OLEDs), electrophoretic displays [9][10][11][12] (EPDs), and flexible liquid crystal displays [13][14][15][16] (LCDs), can be used in flexible-display applications.…”
