Ultra‐narrow border display with a cover glass using liquid crystal displays with a polyimide substrate

Abstract

Plastic liquid crystal displays (LCDs) termed sheet LCDs with transparent polyimide (PI) substrates were constructed. There is a lot of potential to expand the use of these LCDs in LCD applications. Herein, we investigated a structure for sheet LCDs such as high-density main post spacers (PSs) and PI substrates with the aid of a barrier layer to control the residual stress and protect the liquid crystal from moisture.Drawing on this, we propose an ultra-narrow border LCD that makes of the developed sheet LCDs. The most significant improvement is that the four borders of the LCD can be folded to wrap the backlight unit. This LCD was based on various new techniques, including the use of plastic substrates, processing of polarizer films, control of the neutral surface of a bending component based on the sealant width, and the use of a cover glass with a lens effect. We believe that these novel LCDs will be useful in numerous new applications. K E Y W O R D S

“…A 0.2-mmthick LCD panel has been demonstrated. 20 Thin glass substrates have been developed for flexible OLED applications. 21 This knowledge might encourage one to stack an FLU, a thin LCD panel without CFs, an array of luminescent layers, CFs, and IRpfs on a Si-based solar cell.…”
