The driving force of everyone’s efforts since well before the beginning of the LCD and plasma eras has been Sales Manager: Christine von Steiger achieving a large-screen flat-panel TV that can hang on a 413/783-0473, [email protected] wall at a price everyone can afford. Well, here we are. Actually, we have been here for a few years now, but somehow it seems more like a total victory this year than ever before. Today, there are slim, bright, high-quality Editorial Advisory Board HDTVs in homes, businesses, public venues, and everywhere in between. Stephen P. Atwood, Chair If you are shopping for a new TV this year, the choices are almost endless and the Azonix Corp., U.S.A. prices lower than at any previous time in history. Pick a size, pick a brand, pick a set Helge Seetzen of features, pick a store, decide what you are willing to pay, and your holiday shop- TandemLaunch Technologies, Westmont, ping is done. It is safe to say that while there are many differences in features and Quebec, Canada performance among models, almost any set you find for more than $200 is capable of Allan Kmetz giving you a decent HDTV user experience. For less than $500, you can even find Consultant, U.S.A. 50-in. 1080p LCD and 720p plasma TVs at retail stores. Just a year or two ago, these Larry Weber similar sets were selling for twice those amounts or more. Consultant, U.S.A. With these historically low prices, TVs should be flying off the shelves and manu- facturers should be ecstatic, right? Well, not quite. The problem is two-fold. First, most consumers in many parts of the world have already recently made new big- screen TV purchases and there is nothing really wrong with the sets they have. So, Guest Editors demand is soft and sales are sluggish, pushing down prices and margins even further Materials to the point where the ink on the bottom line is turning more red than green. Second, Ion Bita, Qualcomm MEMS at these historically low prices, there is little or no margin left for the retailers, distri- Technologies buters, and manufacturers to make any profits. Downward price pressures brought on eReaders and Tablets by intense competition and weak demand have wiped out traditional markups, and this Jason Heikenfeld, University of has brought on waves of consolidation that are still under way. Cincinnati The hope is that buyers will be tempted by the latest LED backlight version, or Backlighting/LEDs maybe decide to upgrade to a 3-D TV with “smart” features. In those cases, prices Adi Abileah, Planar Systems jump up fairly rapidly based on size and features, with most options priced between Interacting with Displays $1500 and $3500, which feels more like what we were seeing a couple years ago. Geoff Walker, IMS Research Even hopes of selling large volumes of smaller-sized TVs for the kitchen, bedroom, TV Technology and garage are not very high this year because of all the competition from tablets and David Trczinski, Avid smart phones and other so-called “second screen” devices. Sales of those devices have exploded and for many younger people a high-end tablet computer could actually become their “first screen.” Plus, we should not forget that at least for North America Contributing Editors and Europe the economy is weak and TVs, like many other consumer products, are discretionary purchases. Alfred Poor, Consultant Author and industry analyst Pete Putman understands this well and explains how Steve Sechrist, Consultant this has evolved into a really tough period for set manufacturers, who are facing down- Paul Semenza, DisplaySearch ward price pressure and very little consumer demand for high-end features such as 3-D and Internet connectivity.

  • Ambient Contrast Ratio of Lcds and OLED Displays
    Vol. 25, No. 26 | 25 Dec 2017 | OPTICS EXPRESS 33643 Ambient contrast ratio of LCDs and OLED displays * HAIWEI CHEN, GUANJUN TAN, AND SHIN-TSON WU College of Optics and Photonics, University of Central Florida, Orlando, Florida 32816, USA *[email protected] Abstract: We systematically analyze the ambient contrast ratio (ACR) of liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays for smartphones, TVs, and public displays. The influencing factors such as display brightness, ambient light illuminance, and surface reflection are investigated in detail. At low ambient light conditions, high static contrast ratio plays a key role for ACR. As the ambient light increases, high brightness gradually takes over. These quantitative results set important guidelines for future display optimization. Meanwhile, to improve an OLED’s ACR at large oblique angles, we propose a new broadband and wide-view circular polarizer consisting of one linear polarizer and two biaxial films. Good performance is realized. © 2017 Optical Society of America under the terms of the OSA Open Access Publishing Agreement OCIS codes: (120.2040) Displays; (230.3720) Liquid-crystal devices; (160.3710) Liquid crystals.

    1 Introduction 1.1 Flat panel displays A display is an interface containing information which stimulates human vision. Information may be pictures, animation, movies and articles. One can say that the functions of a display are to produce or reproduce colors and images. Using ink to write, draw or print on paper is a traditional display, like a painting or a book. However, the content of such a traditional display is motionless and typically inerasable. In addition, a light source, synthetic or natural, is needed for reading a book or seeing a picture. There are lots of electronic displays that use an electronic signal to create images on a panel and stimulate the human eye. Typically, they can be classified as emissive and nonemissive. Emissive displays emit light from each pixel which constitutes an image on the panel. In contrast, nonemissive displays modulate light, by means of absorption, reflection, refraction and scattering, to display colors and images. For a nonemissive display, a light source is needed. Hence, these can be classified into transmissive and reflective displays. One of the most successful display technologies for home entertainment is the cathode ray tube (CRT), which is in widespread use in televisions (TVs). CRT is already a mature technology which has the advantages of self-emission, wide viewing angle, fast response, good color saturation, long lifetime and good image quality. However, a major disadvantage is its bulky size. The depth of a CRT is roughly equal to the length and width of the panel. For example, a monitor’s depth is about 40 cm for a 19-inch (38.6 cm × 30.0 cm) CRT with an aspect ratio of 4:3.

To achieve full-color displays, three approaches are commonly used: 1) to assemble individual RGB micro-LED pixels from semiconductor wafers to the same driving backplane through pick-and-place approach, which is referred to as mass transfer process; 2) to utilize monochromatic blue micro-LED with a color conversion film to obtain a white source first, and then employ color filters to form RGB pixels, and 3) to use blue or ultraviolet (UV) micro-LEDs to pump pixelated quantum dots (QDs).

  • Appendix a Flat Panel Displays
    Appendix A Flat Panel Displays In the last years, the technological advances enabled flat panel displays (FPDs) to be introduced in a wide range of applications and devices and have enabled applications otherwise impossible, which are limited only by the fantasy of the designer. A.1 Technologies and Classification Other than the LCD, the subject of this book, many other types of flat display technologies have been devised such as: PDP (Plasma Display Panel), LED (Light Emitting Diode) OLED (Organic LED), VFD (Vacuum Fluorescent Display), TFELD (Thin Film Electroluminescent Display), FED (Field Emission Display), DMD (Digital Micro-mirror Machine), PALC (Plasma Addressed LCD), Bistable Displays (including the Electrophoretic and the Nematic Bistable). According to the application and price-to-performance ratio, the most suitable technology has to be chosen. In the following we shall briefly discuss the display technologies that have reached a sufficient development and commercial application. In such a multitude of applications and display types, it is useful to operate a first classification in: Direct view displays and Projection displays. In the first case the name is self explaining, in the second one the image can be projected on a screen either for home/office application or car/airplane application. The image can be also projected on the human eye retina by microdisplays. Then, a second classification, related to the display technologies, must be performed between: Emissive displays and Nonemissive displays In the first case, the device emits light from each pixel. In the second case, the device modulates light (from a light source) by means of absorption, reflection, refraction, and/or scattering mechanisms.

  • Liquid Crystal Display and Organic Light-Emitting Diode Display: Present Status and Future Perspectives
    Light: Science & Applications (2018) 7, 17168; doi:10.1038/lsa.2017.168 OPEN Official journal of the CIOMP 2047-7538/18 www.nature.com/lsa REVIEW ARTICLE Liquid crystal display and organic light-emitting diode display: present status and future perspectives Hai-Wei Chen1, Jiun-Haw Lee2, Bo-Yen Lin2, Stanley Chen3 and Shin-Tson Wu1 Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative study of these two flat panel display technologies. First, we review recent advances in LCDs and OLEDs, including material development, device configuration and system integration. Next we analyze and compare their performances by six key display metrics: response time, contrast ratio, color gamut, lifetime, power efficiency, and panel flexibility. In this section, we focus on two key parameters: motion picture response time (MPRT) and ambient contrast ratio (ACR), which dramatically affect image quality in practical application scenarios. MPRT determines the image blur of a moving picture, and ACR governs the perceived image contrast under ambient lighting conditions. It is intri- guing that LCD can achieve comparable or even slightly better MPRT and ACR than OLED, although its response time and con- trast ratio are generally perceived to be much inferior to those of OLED. Finally, three future trends are highlighted, including high dynamic range, virtual reality/augmented reality and smart displays with versatile functions.
