60.2: Novel Optically Addressable Photochiral Displays Erica Montbach

We show for the first time, a novel optically written bistable cholesteric display using a simple electrode structure and reversible photo addressable azo binaphthyl chiral materials. These displays are inherently high resolution, require no drive electronics and can be made flexible.

56.3: Flexible Ink Jet Printed Conductive Polymer Electrode Cholesteric Display

We report on the first flexible cholesteric display made with ink jet printed conducting polymers as top and bottom electrodes on thin plastic substrates. Ink jet printed conductive polymer electrodes provide ease of patterning as well as enable highly flexible displays. This paper focuses on deposition techniques and trade-offs and benefits of printed flexible electrodes.

New developments in flexible cholesteric liquid crystal displays

Flexible Cholesteric liquid crystal displays have been rapidly maturing into a strong contender in the flexible display market. Encapsulation of the Cholesteric liquid crystal permits the use of flexible plastic substrates and roll-to-roll production. Recent advances include ultra-thin displays, laser-cut segmented displays of variable geometry, and smart card applications. Exciting technologies such as simultaneous laser-edge sealing and singulation enable high volume production, excellent quality control and non-traditional display geometries and formats.

53.4: Novel Pulsed Drive Scheme for Improved Gray-Level Uniformity of Large-Area Cholesteric Displays

A new drive scheme is presented for producing uniform grays over large-area, low-resolution cholesteric liquid crystal displays. Gray-level sensitivity to display non-uniformities is minimized, which simplifies display manufacturing. While applicable to both rigid and flexible displays, the impact on flexible displays will be particularly important with roll to roll manufacturing capability coming online.

Flexible Reflex displays

Flexible, reflective, bistable displays have become the focus of significant research over the past decade due to their appeal for alternative applications requiring low power, small form factor, and flexibility. Some of the first flexible displays to be offered in the market are non-traditional Reflex™ displays in unique and exciting new applications, such as, writing tablets, electronic skins, and smart card displays (Fig. 1).
