— A 3-m-long rugged flexible display having a novel single-plastic-substrate structure has been demonstrated with a coated cholesteric liquid-crystal mixture. The display is designed to be fabricated by a roll-to-roll process to increase productivity at a competitive cost. It has the advantage of having almost no limitation in display length. The high-resolution (300-dpi) monochrome cholesteric liquid-crystal display (ChLCD) can be achieved by using a photo-addressing method. A single-layered 10.4-in. color ChLCD also has been developed with good color and contrast.

An 80ppi ¼ VGA full color, single layer, Reflex™ display with red, green and blue reflecting sub-pixels is reported. A phototunable chiral dopant is UV exposed to produce these colors, and polymer walls keep the colors separate after tuning. We will present details of this development and discuss applications.

A 10 inch full color cholesteric liquid crystal display ChLCD with high reflectivity and high resolution is demonstrated. This display consists only one ChLC panel which is fabricated by the development of the pixelized vacuum filling PVF technique. The reflectivity of our ChLCD was improved to about 26% with 4bit color, its contrast ration is over 6 and the resolution is 100 ppi.

A 10.4-inch full color cholesteric liquid crystal display (ChLCD) with high reflectivity and high resolution by dual stacking is demonstrated. This display consists of two cholesteric liquid crystal (ChLC) panels with the same chirality ChLC but separated by a layer of half-wave plate material allow the reflection of both components of incident circularly polarized light in a single display. Each individual ChLC panel is fabricated by the development of the pixelized vacuum filling (PVF) technique. The reflectivity of our ChLCD is about 26% with 100 ppi resolution and 3-bit color.

To reduce the power consumption and improve the image quality of a full color Cholesteric LCD, low driving voltage Cholesteric LC and crosstalk-free drive schemes have been respectively developed. The developed technologies were integrated into a 5″ full color QVGA Cholesteric LCD with a low-cost single-layer structure. The performance of the display validated the development approaches.

This study developed an ink-jet printing method capable of producing multi-domain alignment liquid crystal displays. Based on the drop-on-demand characteristics of ink jet printing, the inks location in different alignment manners could be defined in one pixel. This paper describes two practical applications. The first involves integrating the hybrid aligned zone with the homeotropic aligned area in one pixel to create a multi-domain alignment when the voltage is applied. This proposed method achieved a wide viewing angle. The second, similar approach using ink jet printing was performed on a single-cell-gap transflective liquid crystal display. A 2.4-in 170-ppi prototype demonstrates mass-production feasibility.
