“…The fabrication process we have developed allows complete LC cells and organic TFTs to be manufactured on TAC film instead of glass, using standard flat-panel display equipment [3][4][5][6]. Because both the organic TFTs and LC cell materials are processable below 100°C, this allows materials with a low Tg such as TAC film (Tg~150°C) to be used as a substrate for the first time.…”

One of the challenges in see-through AR headsets is rendering outdoor scenes when there is high ambient brightness. This is because in such conditions the luminance of real objects becomes comparable to or higher than the maximum luminance of the virtual object, severely impacting the virtual image contrast. One solution to this is to use LC-based ambient dimming cells to modulate background brightness. However, conventional glass LC cells add unwanted weight and volume to headsets and cannot be biaxially curved. This talk will explain how a breakthrough liquid crystal optics technology built on ultra-thin, light bioplastic films instead of glass uniquely enables active-matrix pixelated ambient dimming on biaxially curved surfaces.

“…At FlexEnable we have followed with interest the developments of liquid crystal lenses and have taken our own approach to their design and manufacture using our low-temperature liquid crystal cells, which were initially developed for Organic Liquid Crystal Display (OLCD). Our unique technology allows us to make ultra-thin (<100um) and ultra-light (<0.25g for an eyeglass size) LC cells using standard display fabrication equipment [3][4][5][6].…”

Head mounted display systems are widely available, yet there remain key technical challenges to increase their utility in the market. One such challenge is the conflict for human vision between accommodation and vergence when viewing virtual images. At worst this leads to an uncomfortable viewing experience and at best it limits the stereoscopic range. The transition from fixed focal length optics to systems that can be tuned to match the virtual content promises to change to this paradigm. In this paper we describe a tunable liquid crystal lens based on Fresnel optics that allows variable focus of the virtual image. Crucially this is the first time this type of lens has been made with ultra‐thin, light bioplastic films instead of glass, uniquely enabling attractive product form factors.
