Published: July 2014

AbstractIn this article we disclose a method to fabricate liquid crystals (LC) Fresnel zone lens (FZL) with high efficiency. The LCFZL based on patterned planar aligned regions has been prepared by means of two‐step photoalignment technique. The proposed binary‐phase LCFZL manifests 39% diffraction efficiency at the focal point which is close to the theoretical limit 41%. Moreover, because of lower driving voltage and faster response time these elements could find application in many modern devices such as 2D/3D switchable display, see‐through display and etc.
P‐106: Pretilt Angles and Liquid‐Crystal Director‐Deformation Profiles of Inverse Twisted Nematic Liquid Crystal Cells
Authors: Wang Sheng‐Ya , Lin Chia‐Yi , Yang Kei‐Hsiung 
Published: July 2014

AbstractWe have developed a simple optical method and analyzed data by extended Jones matrix method to obtain pretilt angles of invesed twist nematic (ITN) and tilted homeotropic liquid crystal (LC) cells. We have compared the measured pretilt angles of the ITN cell with those of an accompanying tilted homeotropic (ATH) cell. The results showed increasing discrepancies between them with increasing rubbing depth for LC alignments. However, these discrepancies could be explained by assuming that the surface‐LC tilt angle of the ITN cell was equal to the measured pretilt angle of the ATH cell to generate a LC director‐deformation profile within the ITN cell based on Oseen‐Frank elastic continuum theory with infinite anchoring energy. The average of the LC tilt angles over this profile was equivalent to the measured pretilt angle of the ITN cell.

Published: July 2014

AbstractWe have investigated diluter effects on the Debye relaxation frequency, and electro‐optics of polymer‐stabilized blue phase liquid crystals (BPLC). The relaxation frequency can be increased by adding a small amount of diluters, which benefits high frequency operation of BPLC. Some diluters significantly decrease the BPLC response time while maintaining similar Kerr constant.
P‐113: Photoalignment Technology for High Performance IPS‐LCDs: IPS‐NEO Technology
Authors: Kunimatsu Noboru , Sonoda Hidehiro , Hyodo Yosuke , Tomioka Yasushi 
Published: July 2014

AbstractWe have developed our original photoalignment technology, IPS‐NEO, which improves azimuthal anchoring strength to a level equivalent to that of rubbing, and reduces photoirradiation energy to a level required for mass production. We have also clarified that the anchoring strength of IPS‐NEO does not depend on the unevenness of the surface of the substrates, nor does it depend on the bias angle between the alignment axis and the direction of the electrodes. With this technology, we realized practical application of photoalignment for high performance IPS‐LCDs.

Published: July 2014

AbstractIon movement in liquid crystal displays plays crucial role in residual dc associated with image sticking. This paper investigatesadsorption and desorption of ions at interfaces between liquid crystal and alignment layer depending on resistivity of alignment layer and sign of dielectric anisotropy of liquid crystal in thefringe field switching (FFS) liquid crystal cell. Our studies show that the resistivity of alignment layer mainly determines ion movement such that the one with lower resistivity shows faster absorption and desorption at the interface than that of the one with higher resistivity.

P‐121: Electro‐Optical Properties of Inverse Twisted Nematic Cells with Different Pretilt Angles
Authors: Lin Chia‐Yi , Wang Sheng‐Ya , Yang Kei‐Hsiung 
Published: July 2014

AbstractIn general, the optical properties of any general twisted nematic cells consist of two complementary effects: LC‐birefringent and LC‐director‐twist effects. In this paper, electro‐optical properties of ITN cells without chiral dopants with different pretilt angles have been investigated for the first time to differentiate the LC‐birefringent effect from the LC‐twist effect. We have investigated transient responses of the ITN cell and found that the optical‐bounce (LC backflow) effect of the ITN cell occurred in the transition from homeotropic‐to‐planar states under high applied voltages where the LC‐twist‐effect dominated. We have also explained the superiority of high contrast ratio of the ITN cell over the tilted homeotropic cell with same pretilt angle due to mutual compensation between two surface‐LC layers adjacent to ITN‐cell substrates in quiescent state.

Published: July 2014

AbstractA spatial light modulator (SLM) modulates one of the properties (amplitude, phase, polarization) of an optical wavefront that may be electrical, optical or pressure sensitive. This SLM is formed via surface‐assisted assembly of a two‐dimensional array cholesteric liquid crystal bubbles in an electro‐optical cell. This SLM device serves as an input transducer enabling active or bistable processing operations to control of light transmission or scattering. This finding will be useful for optical display and touch applications.

P‐140: Hybrid Analog‐Digital Driving Method for High Definition AMOLED
Authors: Chen Shuming , Sun Xiaowei , Kwok Hoi‐Sing 
Published: July 2014

AbstractA hybrid analog‐digital driving method has been proposed for driving the AMOLED. A frame has been divided into N subframes corresponding to the N bit image data. Each subframe is binary weighted by either the duration or the pixel “on” luminance. The pixel “on” luminance is controlled by the voltage level of the common cathode of the OLED (Vcom). By changing the amplitude of Vcom, the “on” luminance can be binary varied. The proposed driving scheme can be applied to a 4K or even 8K UHD AMOLED with 8‐bit gray level.

Published: July 2014

AbstractAlthough collagen with outstanding biocompatibility has promising application in corneal tissue engineering, the mechanical properties of collagen‐based scaffolds, especially suture retention strength, must be further improved to satisfy the requirements of clinical applications. This article describes a toughness reinforced collagen‐based membrane using silk fibroin. The collagen‐silk fibroin membranes based on collagen [silk fibroin (w/w) ratios of 100:5, 100:10, and 100:20] were prepared by using silk fibroin and cross‐linking by 1‐ethyl‐3‐(3‐dimethylaminopropyl) carbodiimide. These membranes were analyzed by scanning electron microscopy and their optical property, and NaCl and tryptophan diffusivity had been tested. The water content was found to be dependent on the content of silk fibroin, and CS10 membrane (loading 10 wt % of silk fibroin) performed the optimal mechanical properties. Also the suture experiments have proved CS10 has high suture retention strength, which can be sutured in rabbit eyes integrally. Moreover, the composite membrane proved good biocompatibility for the proliferation of human corneal epithelial cells in vitro. Lamellar keratoplasty shows that CS10 membrane promoted complete epithelialization in 35 ± 5 days, and their transparency is restored quickly in the first month. Corneal rejection reaction, neovascularization, and keratoconus are not observed. The composite films show potential for use in the field of corneal tissue engineering. © 2014 Wiley Periodicals, Inc.
