Active Matrix Liquid Crystal Displays

Active matrix liquid crystal displays (AMLCDs) are the preferred choice when thin, low power, high quality, and lightweight flat panel displays are required. Here is the definitive guide to the theory and applications of AMLCDs.Contemporary portable communication and computing devices need high image quality, light weight, thin, and low power flat panel displays. The answer to this need is the color active matrix liquid crystal display (AMLCD). The rides of AMLCD technology over less than two decades to undisputed dominance as a flat panel display has been breathtaking, and designers of portable devices need a thorough understanding of the theory and applications of AMLCDs. Willem den Boer, a holder of over 30 patents in imaging technologies, has created this guide to AMLCD theory, operating principles, addressing methods, driver circuits, application circuits, and alternate flat display technologies (including active matrix flat panel image sensors). Numerous design and applications examples illustrate key points and make them relevant to real-world engineering tasks.

An unprecedented look into the basic physics, chemistry, and technology behind the LCD Most notably used for computer screens, televisions, and mobile phones, LCDs (liquid crystal displays) are a pervasive and increasingly indispensable part of our lives. Providing both an historical and a business-minded context, this extensive resource describes the unique scientific and engineering techniques used to create these beautiful, clever, and eminently useful devices. In this book, the history of the science and technology behind the LCD is described in a prelude to the development of the device, presenting a rational development theme and pinpointing innovations. The book begins with Maxwell's theory of electromagnetism, and the ultimately profound realization that light is an electromagnetic wave and an electromagnetic wave is light. The power of mathematical physics thus was brought to bear upon the study of light, and particularly the polarization of light by material bodies, including liquid crystals. After a brief historical description of polarization, a physical interpretation provides substance to the mathematical concepts. Subsequent chapters cover: Thermodynamics for liquid crystals The Maier-Saupe mean field, phenomenological, static continuum, and dynamic continuum theories The transistor and integrated circuit Glass, panels, and modules The calculus of variations The active matrix Semiconductor fabrication The global LCD business Additionally, the book illustrates how mathematics, physics, and chemistry are put to practical use in the LCDs we use every day. By describing the science from an historical perspective and in practical terms in the context of a device very familiar to readers, the book presents an engaging and unique view of the technology for everyone from science students to engineers, product designers, and indeed anyone curious about LCDs. Series Editor: Anthony C. Lowe, The Lambent Consultancy, Braishfield, UK The Society for Information Display (SID) is an international society, which has the aim of encouraging the development of all aspects of the field of information display. Complementary to the aims of the society, the Wiley-SID series is intended to explain the latest developments in information display technology at a professional level. The broad scope of the series addresses all facets of information displays from technical aspects through systems and prototypes to standards and ergonomics.

This high efficiency active matrix liquid crystal display (HEAMLCD) effort examined several alternatives to increasing the total power efficiency of an AMLCD flat panel display (FPD). It was determined that the color filters passed just one-sixth of incident light and that a re-design of the addressed cell assembly (ACA) based on color separation physical phenomena represented the best new technology opportunity to improve overall display power efficiency. Current liquid crystal display (LCD) sub-pixels are covered by red, green, or blue absorptive color filters; this method discards two-thirds of available white light by structure while transmitting just 50% of the desired color. Micro-optical elements based on refractive, diffractive, or interferometric color separation, were selected for pursuit in this effort. A diffractive color separation filter (DCSF) was designed to separate the colors and focus the desired red, green, blue wavelength bands onto the subpixel apertures. The black matrix already used in AMLCD designs is used to block the spill-over of undesired wavebands from adjacent subpixels. Several prototypes of a DCSF were designed, fabricated, tested, analyzed, and reported. An alternative approach using reflective color separation (RCS) dichroic filters was also tested. Several other potential techniques for improving the efficiency of AMLCD displays, including inorganic light emitting diode (LED) backlight technology, were examined and are discussed.
