Book excerpt: The special feature of the book is the in depth treatment of both the electro-optic effects and the addressing schemes of liquid crystal displays elucidating their interdependence. After basic explanations readily understandable for students and stimulating for engineers, physicists and chemists, the reader is gradually led to the latest developments such as vertically aligned and mixed mode TN-displays, compensation foils, multiple line and low power addressing, transistor driven LCOS-devices with DRAM and SRAM addressing and TFT-addressing of transmissive displays with a 92% aperture ratio. The results are analytically derived and not merely stated to enhance insight and the capability to tailor displays to individual needs or to perform novel designs. Towards this aim the propagation of light with the help of Jones vectors, four different characterizations of the state of polarization and the operation as well as the passive and active matrix addressing of all LCDs, like nematic, polymer dispersed, guest host and bistable devices is explained. Besides the mainstream twisted and supertwisted nematic LCDs attention is drawn to bistable ferroelectric, chiral nematic and modified nematic LCDs as they are most promising for future portable low power systems. Tables on display formats and units for the measurement of displays finally render the book suitable as a reference for experts working in the field and as a textbook for universities or display courses. The forefront of research is reached by the treatment of plastic substrates, the replacement of vacuum processes by less expensive printing and low temperature fabrication of a-Si- and poly-Si-TFTS.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the development of liquid crystal displays (LCDs) and liquid crystal materials (LCs) in Japan. The Committee of Organic Materials Research for Information Sciences of the Japan Society for the Promotion of Science (JSPS) planned the book to document essential LCD innovations and developments since the beginnings of the field-effect LCD technology in 1970. The book illustrates the remarkable effort and progress behind those flat, lightweight, and high-information-content LCDs that have become the indispensable human–machine interface for virtually all electronic devices. In contrast to other publications on this topic, the book illustrates the interdisciplinary character of the LCD technology and its crucial importance for technological progress of the field far beyond displays. It also gives insights into breakthrough innovations not revealed in other publications. Moreover, prospects for the development of LC research toward new fields of applications are provided. In line with its interdisciplinary character, the book targets researchers in basic science as well as engineers and researchers in industry.

Available in PDF, EPUB and Kindle. Book excerpt: Liquid crystal display (LCD) is an electronic display device that operates by applying a varying electric voltage to a layer of liquid crystal, thereby inducing changes in its optical properties. LCDs are commonly used for portable electronic games, as viewfinders for digital cameras and camcorders, in video projection systems, for electronic billboards, as monitors for computers, and in flatpanel televisions. A working LCD consists of several components: display glass, drive electronics, control electronics, mechanical package, and power supply. The display glass --between which the liquid crystals lie--is coated with row and column electrodes and has contact pads to connect drive electronics (electric current) to each row and column electrode. The drive electronics are integrated circuits that supply current to ""drive"" the row and column electrodes. The control electronics are also integrated circuits. They decode and interpret the incoming signals--from a laptop computer, for example--and send them to the drive electronics. The mechanical package is the frame that mounts the printed circuit boards for the drive and control electronics to the display glass.Features of Liquid Crystal Display Materials and Processes embraces advanced and revised contributions and covers theoretical modeling for optoelectronics and nonlinear optics, along with experimental methods, new schemes, new approach and explanation which extends the display technology for laser, semiconductor device technology, medicine, biotechnology, etc. Liquid crystal displays (LCDs) consist of liquid crystals that are activated by electric current. They are used most frequently to display one or more lines of alpha-numeric information in a variety of devices: fax machines, laptop computer screens, answering machine call counters, scientific instruments, portable compact disc players, clocks, and so forth. The most expensive and advanced type--active matrix displays--are even being used as screens for handheld color TVs. Eventually, they may be widely used for large screen, high-definition TVs. The innovative idea, approach, and facts described here will be profitable for the readers to find a sustainable solution in a fundamental study and in the industry.

Available in PDF, EPUB and Kindle. Book excerpt: During our Phase I research, we advanced materials synthesis and evaluation techniques needed to develop ferroelectric liquid crystals into a useful second-order nonlinear optical material. We developed a technique for determining the second-order nonlinear susceptibility by measuring the electro- optic coefficient r22 at 633 nm, using modulation frequencies between 100 KHz- 100 MHz. We evaluated two specially synthesized FLCs by measuring their r22 coefficients: previously existing MX-5679 and recently synthesized W-399, both based on a nitrobenzene hyperpolarizable moiety. Results show an increasing r22 with increasing spontaneous polarization. We also partially evaluated a new FLC material, W-371, with an ortho-situated nitroaniline hyperpolarizable moiety. Since the liquid crystalline and the linear and nonlinear materials parameters FLCs have a temperature dependence, we examined existing FLC polymers for a FLC to glass phase and discovered a polymeric/FLC system that potentially could be used to reduce temperature dependent materials properties. Our FLC synthesis efforts concentrated on synthesis of Hoffman-LaRoche compounds roche 1 and roche 2. Unfortunately, we were unable to duplicate their synthesis and instead developed an alternative core that could yield FLCs with a higher second-order nonlinear susceptibility.
