New Display Technologies (Crts), Displays Have Become Ubiquitous and Have Taken Many Different Forms 1.0 Introduction Mini Briefing Electronic displays are one of the fastest-growing worldwide technologies. Once reserved for televisions and computers, and composed of large cathode-ray tubes New Display Technologies (CRTs), displays have become ubiquitous and have taken many different forms. Flat-panel displays are overtaking the CRT and are being used in larger quantities for Steve Statham portable computers, a variety of handheld devices, desktop computers and televisions, as well as tiny microdisplays, which are being used in projection televisions, for near-eye applications, where a virtual screen is presented to the viewer. The world of displays is Advances in new display technologies are rapidly changing to meet the evolving needs of the beginning to open up many new possibilities to electronic-device user. consumers and manufacturers. Unfortunately there is always a large time lag between the discoveries made, and the time when practical applications 2.0 Applications finally appear. Even once they have been incorporated into everyday items, they are The electronic-display device industry caters mainly for the sometimes expensive. automation and electronics appliance industries. Characteristic of OEM products, the growth of the display However, major developments are now taking industry is directly linked to the demand trends in end-user place in a variety of display materials with the markets.

This briefing examines the computers, mobile phones and other electronic potential of the display market and discusses the automation products) is directly linked to the levels of current state of each display technology. It also economic development. This end-use market is comments on some of the emerging technologies concentrated in the US and the developed European emanating from display companies around the countries. The Asia-Pacific region, with the highest world. population and improving standards of living and automation, presents an enormous future market. During the 1990s, the electronic-display device industry was dominated by CRTs in terms of production volumes of Published in 2005 by PRIME Faraday Partnership, Wolfson and the number of players. The CRT, being the standard School of Mechanical and Manufacturing Engineering, display used in televisions and PC monitors, enjoyed a Loughborough University, Loughborough, Leics LE11 3TU large market. Although non-CRT displays led the CRT in © 2005 Pera Knowledge production-value terms, the unit production was negligible ISBN 1-84402-055-X in comparison. Among the non-CRT displays, also known as flat-panel displays, the liquid-crystal display (LCD) posed an immediate threat to the CRT. With continuous refinement of its features, the LCD was seen as an alternative to CRT. The portable PC segment – the major end-market for the LCD – has also witnessed major growth.

  • Tvs Final Report
    Revising the Ecolabel Criteria for Televisions – Final Report April 2008 Executive Summary Background The existing EU Ecolabel criteria for Televisions (Commission Decision 2002/255/EC, March 2002) were developed at a time when the EU TV market was dominated by Cathode Ray Tube (CRT) technology. Today however, the market has changed markedly such that new technologies including Liquid Crystal Display (LCD) and Plasma Display Panel (PDP) technologies account for an increasing market share driven by consumer preference for larger screen sizes. Other developments are important drivers for change too including the development of High Definition and Digital television. These developments mean that the existing criteria’s applicability in the rapidly changing market place is becoming increasingly marginalised. Indeed the existing criteria’s relevance to non-CRT technology is questionable. Consequently, the TV criteria are in urgent need of an update if they are to keep pace with the market. AEA was pleased to work with the Commission in undertaking the revision exercise over the period Spring 2006 to Spring 2008. We were assisted by the ad-hoc working group (AHWG) that met twice during the period to discuss and inform the revision. AHWG members and others also lent advice to the project via email and individual meetings that were immensely helpful. In parallel with our work, other important work in support of product policy was underway that helped inform the ecolabel revision, namely: 1 The revision of the TV energy testing methodology. The importance of this work is that it is being undertaken in recognition of the fact that the TV products have changed markedly and that as a result the existing test method is inadequate for non-CRT technology.

  • Various Display Technologiess
    VARIOUS DISPLAY TECHNOLOGIESS Mr. Virat C. Gandhi1 1Computer Department, C. U. Shah Technical Institute of Diploma Studies Abstract—A lot has been invented from the past till now in regards with the display technologies. It gives an immense life to electronic device when good display technology are being used. Now a days displays are coming in various sizes for different portable devices like smart phones, tablets, smart watch, televisions, laptops etc. People are expecting better display no matter what device they use. In this paper I have given an overview of some of the past technologies to the technologies till now. Flat-panel displays use Liquid-crystal display (LCD) technology to make them much lighter and thinner when compared with a traditional monitor. A liquid crystal display consists of an array of tiny segments (called pixels) that can be manipulated to present information. Plasma panels, also called gas discharge displays, are constructed by filling the region between two glass plates with a mixture of gases that usually include neon. In LED, A matrix of diodes is arranged to form the pixel positions in the display, and picture definition is stored in refresh buffer. OLED (Organic Light Emitting Diode) technology relies on the organic materials. Keywords— Display Technology; LCD; LED; Flexible display; Curved display; I. INTRODUCTION In today’s smart world, people are carrying smart devices all over the places they visit. Wherever people are they are surrounded or accompanied by display devices, such as smart phones, tablets, notebooks and advertising screens. Different devices uses different display technologies to enrich devices facilities.

  • Light-Emitting Diode - Wikipedia, the Free Encyclopedia
    Light-emitting diode - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Light-emitting_diode From Wikipedia, the free encyclopedia A light-emitting diode (LED) (pronounced /ˌɛl iː ˈdiː/[1]) is a semiconductor Light-emitting diode light source. LEDs are used as indicator lamps in many devices, and are increasingly used for lighting. Introduced as a practical electronic component in 1962,[2] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness. When a light-emitting diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of Red, green and blue LEDs of the 5mm type 2 the semiconductor. An LED is usually small in area (less than 1 mm ), and Type Passive, optoelectronic integrated optical components are used to shape its radiation pattern and assist in reflection.[3] LEDs present many advantages over incandescent light sources Working principle Electroluminescence including lower energy consumption, longer lifetime, improved robustness, Invented Nick Holonyak Jr. (1962) smaller size, faster switching, and greater durability and reliability. LEDs powerful enough for room lighting are relatively expensive and require more Electronic symbol precise current and heat management than compact fluorescent lamp sources of comparable output. Pin configuration Anode and Cathode Light-emitting diodes are used in applications as diverse as replacements for aviation lighting, automotive lighting (particularly indicators) and in traffic signals.

  • Technology Brief 6: Display Technologies
    106 TECHNOLOGY BRIEF 6: DISPLAY TECHNOLOGIES Technology Brief 6: Display Technologies From cuneiform-marked clay balls to the abacus to today’s digital projection technology, advances in visual displays have accompanied almost every major leap in information technology. While the earliest “modern” computers relied on cathode ray tubes (CRT) to project interactive images, today’s computers can access a wide variety of displays ranging from plasma screens and LED arrays to digital micromirror projectors, electronic ink, and virtual reality interfaces. In this Technology Brief, we will review the major technologies currently available for two-dimensional visual displays. Cathode Ray Tube (CRT) The earliest computers relied on the same technology that made the television possible. In a CRT television or monitor (Fig. TF6-1), an electron gun is placed behind a positively charged glass screen, and a negatively charged electrode (the cathode) is mounted at the input of the electron gun. During operation, the cathode emits streams of electrons into the electron gun. The emitted electron stream is steered onto different parts of the positively charged screen by the electron gun; the direction of the electron stream is controlled by the electric field of the deflecting coils through which the beam passes. The screen is composed of thousands of tiny dots of phosphorescent material arranged in a two-dimensional array. Every time an electron hits a phosphor dot, it glows a specific color (red, blue, or green). A pixel on the screen is composed of phosphors of these three colors. In order to make an image appear to move on the screen, the electron gun constantly steers the electron stream onto different phosphors, lighting them up faster than the eye can detect the changes, and thus, the images appear to move.
