Highly conductive and transparent zinc oxide thin films were prepared on cleaned Corning Eagle 2000 glass substrates by chemical bath deposition (CBD) using Zn(NO 3 ) 2 and (CH 3 ) 2 NHBH 3 ; the effects of annealing on the structural, electrical and optical properties were investigated. The electrical properties of the film were greatly affected by annealing. Structural characterization was performed by x-ray diffraction and field emission scanning electron microscopy. The thin film had a low resistivity of 2.9 9 10 À2 X cm, an average transmittance of 81.2%, and a bandgap of 3.23 eV (which is in the visible range) when the film was annealed at 600°C in Ar + H 2 . The results demonstrated that a low-resistivity and high-transmittance zinc oxide film can be prepared by CBD, which makes the process readily applicable for a roll-to-roll process.

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 4-bit 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.

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 ink's 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.
