P - 40 : Photo - Aligned VAN LCD
نویسنده
چکیده
Photo-aligned VAN-LCD was developed using the photosensitive polyimide (PI) JALC 2021-R2, illuminated by obliquely incident non-polarized light. It has been shown that the combination of these aligning materials with newly developed derivative of sodium salt of benzidine –3,3’-disulfonic acid (SD-1) gives a reliable and a good electro-optical performance. The response time, contrast ratio and VHR of photo-aligned VAN-LCD were comparable with the conventional VAN-LCD, where the common “rubbing” technique was used.

Multidomain LCDs and Complex Optical Retarders Generated by Photo-Alignment
Photo-alignment of liquid crystal displays (LCDs) with our linear photo-polymerisation (LPP)technology enables well defined boundary conditions such as high anchoring strength and stable, pretilt angles [1,2]. We report a photo-aligned four-domain vertical aligned nematic (VAN)-LCD. The display is compensated by a new VAN-compensator which is based on our LPPand liquid crystal polymer (LCP)tech...

Photoalignment possesses obvious advantages in comparison with the usually “rubbing” treatment of the substrates of liquid crystal display (LCD) cells. The liquid crystal photoalignment is nano-technology, as the thickness of the alignment layer is about 2-15 nm. The application of the photo-alignment and photo-patterning nano technology for the new generation of photonic and display devices wi...

Jae-Hong Park Yoonseuk Choi Tae-Young Yoon Chang-Jae Yu Sin-Doo Lee Abstract — We report on a new method of fabricating a vertically aligned multi-domain liquid-crystal display (LCD) using surface-relief gratings. A linear array of surface-relief gratings was produced by using a photosensitive polymer material coated on glass substrates by the illumination of the UV light through a photomask. T...

A Uniform Lying Helix (ULH) liquid crystal device (LCD) fabricated by utilizing the characteristics of shear flow alignment as well as dielectric anisotropy was demonstrated. Cholesteric liquid crystals with a short helical pitch can exhibit an electric field-induced tilt. These experimental results indicate that it is possible to realize a high-speed response flexible LCD using plastic substra...
متن کاملWESPE: Weakly Supervised Photo Enhancer for Digital Cameras
Low-end and compact mobile cameras demonstrate limited photo quality mainly due to space, hardware and budget constraints. In this work, we propose a deep learning solution that translates photos taken by cameras with limited capabilities into DSLR-quality photos automatically. We tackle this problem by introducing a weakly supervised photo enhancer (WESPE) – a novel image-to-image Generative A...
