We propose a novel design of the single cell gap transflective LCD. By using the photo-alignment technique, we fabricated a transflective LCD with the hybrid and homogeneous alignments in reflective and transmitting regions respectively. The higher aperture ratio and simpler process are the features of our design while compared to the design of dual cell gap. The experimental results showed good performances regarding to VHR, RDC and anchoring effects.

— Several leading technologies for flexible liquid-crystal displays have been developed recently at ERSO. The roll-to-roll compatible techniques, polymer-added liquid crystal, have been applied on a film-like substrate. A flexible black-and-white cholesteric liquid-crystal display was also implemented by photo-induced phase separation. Color filters placed on a plastic substrate by a low-temperature manufacturing process was successfully fabricated. A novel design of a wide-viewing-angle color plastic LCD was also proposed.

A novel method to realize the good performance of transflective LCD is indicated. In one pixel, two LTPS (Low-temperature poly-Si) TFT devices control the optical intensity of the transmissive and reflective regions respectively. We call this way as double gamma method (DGM). Uni-gap transflective LCD attached the DGM will have both merits of simplifying processes and good legibility. Meanwhile, we show the experimental results of optical characteristics with uni-gap homeotropic panel design. It obviously shows that high contrast ratio and wide viewing angle have been achieved.

Influences of anti-reflection and anti-glare surface treatments, radius of curvature and ambient illuminance on legibility and visual fatigue of reflective-type displays were studied. The results showed that legibility and visual fatigue mainly depended on the surface treatment, and better surface treatment can improve legibility and reduce visual fatigue especially in the intense ambient illumination. Surface treatments of 0.8% anti-reflection and 44% anti-glare show the same visual performance.

We have developed a high contrast micro-cell liquid crystal display by microstructure replication technology. This novel flexible LCD technology comprises micro-cell replication process, alignment treatments, and cell assembly process. Compared with photopolymerisation-induced phase separation, the micro-cell LCD has higher contrast ratio, and reliable manufacturing process. This technology can be a good solution for high performance flexible LCD.

A novel hybrid display pixel structure is proposed. This pixel structure consists of organic light-emitting diodes (OLEDs) and reflective liquid crystal displays to form an emi-flective display. With a single pixel circuit and proper driving method, the pixel circuit can drive LC cells and OLEDs in one display system. Moreover, a compatible fabrication process of the hybrid device has been examined. By utilizing the reflective LCD, the wash-out phenomenon of OLED under bright ambient light can be compensated.

A novel hybrid LCD technology has been developed. By replacing a glass color filter with a plastic color filter, a lighter and thinner hybrid LCD can be obtained. A 4 QVGA prototype has been demonstrated. A hybrid LCD can reduce 35% thickness and 36% weight compared with a conventional LCD with 2 glass substrates. This technology can be a good solution for portable display.

A microstructure replication technique to make a high contrast micro-cell LCD has been developed. The robust microstructure can sustain the cell gap very well. Compared with the traditional photopolymerisation-induced phase separation, the micro-cell LCD has higher contrast ratio and more reliable manufacturing process. This technique could be applied in the high performance and low cost flexible LCDs.
