Multidomain LCDs and Complex Optical Retarders Generated by Photo-Alignment
نویسندگان
چکیده
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)technology. The four-domain VAN-LCD exhibits an excellent off-state angular brightness performance which exceeds crossed polarizers. To further simplify photo-patterning of LPPalignment, an alignment master is proposed which generates complex alignment patterns in a single exposure step. An example of a dual-domain 80° TNLCD is presented which is LPP-photopatterned via the new master.

Volume Photo-Aligned Retarders
Coated retarders based on liquid crystal materials are typically aligned by brushing or photo-alignment. Recently, we have managed to combine the aligning and retarder function into a single material. Alignment of the new volume photo-alignable retarder (VPR-) material is induced in the bulk upon exposure to linearly polarized light. The new alignment mechanism opens up a new dimension for the ...
متن کاملLiquid Crystal Materials and Liquid Crystal Displays
Since the early 1970s, three major prerequisites have brought the success of the liquid crystal display (LCD) technology to its key role of today. Namely, the discovery of electro-optical field-effects on which the displays are based, the successful search for liquid crystals (LCs) with material properties that meet the complex requirements of electro-optical effects and render the effects appl...
متن کامل45.4: Azo-Dye Alignment for Displays and Photonics
Liquid crystal photo-alignment using azo-dyes for display and photonics applications is discussed. Various types of the glass and plastic substrates are used. Special types of 3D LC alignment, LC alignment inside thin micro tubes, and LC cladding layers in Si based waveguides and grating surface are concerned. The azo-dye photoalignment of polymerized LC films used as optical elements, such as ...
متن کاملThe Effect of pH on the Optical Band Gap of PbSe Thin Film with Usability in the Quantum Dot Solar Cell and Photocatalytic Activity
This study was an attempt to provide a simple solution processed synthesis route for Lead Selenide (PbSe) nanostructure thin films using the chemical bath deposition (CBD) method which is commercially available in inexpensive precursors. In the CBD method, the preparation parameters play a considerable role and determine the nature of the final product formed. Known as two main factors, the eff...
متن کاملOptical Alignment Technique To Improve LCD Quality and Price
Liquid crystal displays (LCDs) are incorporated into myriad technologies ranging from automated teller machines (ATMs) and computers to kitchen appliances and automotive dashboards. Although American businesses and consumers spend billions each year on these types of equipment, LCD brightness and clarity problems persist, and the high costs associated with LCDs remain. For years, the Asian mark...
