...DIFFERENT TYPES OF DISPLAYS 1. Cathode Ray Tubes (CRT) Technology This technology has been in use for more than 100 years, and is found in most televisions and computer monitors. Beams of electrons, from an electron gun are projected towards the fluorescent screen, within a vacuum, and each time it hits the screen, a phosphor dot lights up inside the glass tube, and thus illuminating active protons of the screen. Repetitions through the screen form a complete image. The image colour depends on the intensity of the three beams of RED, BLUE and Green. The screen is usually made of thick glass to prevent the emitting of x-rays to the environment. The tube has high stress due to the presence of the vacuum which can cause an explosion if the outer glass was to break. These types of screens are very hard to recycle because they have high concentration of lead and phosphors 2. Liquid Crystal Display (LCD) Technology This technology uses the light modulating properties of liquid crystals. This display uses two sheets of polarizing material with a liquid crystal solution between them (thus the name liquid crystal display). An electric current passed through the liquid causes the crystals to align so that light cannot pass through them, acting like a filter. The screen is then put in front of a light source in order to produce images. When light falls on a pixel on the screen, the pixel appears black but change in the amount of voltage flowing in each pixels results in varying amount...

...the general process of using a computer can be frustrating. A “touch-screen” made it much easier for a user to navigate around their computer, cell phone, laptop or tablet. Not only did the touch-screen make things more simple, it also made devices smaller and more portable. There is no need for a physical keyboard if you can use a touch keyboard built right into your device. HISTORY E.A. Johnson developed the theory of a touch-screen in 1969. This touch-screen was of CAPACITIVE technology and developed for air traffic control. He also developed a RESISTIVE technology around the same time. The two different types remain the most popular still to this day. CAPACITIVE TECHNOLOGY Capacitive screens are made up of 3 key components: first, a glass substrate surface; then, a transparent conductive layer; and last, a thin transparent surface. Capacitive technology works when a person touches the screen, a charge is transferred to the body and back to the screen. The device recognizes the charge or touch; Then, the processor computes the specific instruction back to the screen of the user. Smartphones and tablets typically use capacitive technology. RESISTIVE TECHNOLOGY A resistive screen is made up of 4 key layers: first, a glass substrate surface; then , non-conductive separator dots; next, a transparent conductive layer; and finally, a flexible transparent surface. When a resistive screen is pressured the top sheet is pushed back toward the second sheet; creating...

...A touchscreen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with one or more fingers. Some touchscreens can also detect objects such as a stylus or ordinary or specially coated gloves. The user can use the touchscreen to react to what is displayed and to control how it is displayed (for example by zooming the text size). The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or any other intermediate device (other than a stylus, which is optional for most modern touchscreens). Touchscreens are common in devices such as game consoles, all-in-one computers, tablet computers, and smartphones. They can also be attached to computers or, as terminals, to networks. They also play a prominent role in the design of digital appliances such as personal digital assistants (PDAs), satellite navigation devices, mobile phones, and video games. The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are popular in the medical field and in heavy industry, as well as in kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display's content. Historically, the touchscreen sensor and its accompanying...

...body. . The EMFs generated by your screen and machine could be seriously damaging your health. The Bad Effects Of Computer Radiation… We’ll examine the EMF radiation from different types of desktop and laptop computers, what that means for your health, and the SafeSpace products that can protect you while you work, surf and socialize online. What is Computer Radiation & Where Does it Come From? CRT (Cathode Ray Tube) screen radiation - If your desktop monitor (or TV) is a few years old and has a deep cabinet, chances are it’s a CRT. CRTs are by far the most dangerous type of screen. • Few desktop computers are made with CRT screens anymore (though some video gamers still prefer them). • The images produced by CRT screens involve a number of processes, including the front of the tube being scanned downward in a pattern of lines, electron beams “sweeping” an image across the screen by modulating their intensity, a coil generating magnetic field and more. The Health Dangers of CRTs • Small amounts of radiation (x-ray frequencies and others) are emitted as the electrons sweep the screen. • At close range, this radiation (literally pulsating fields of energy) puts biological stress on humans, animals and plants. • CRTs also operate at an extremely high voltage, which continues on long after the computer has been turned off. LCD ( Liquid Crystal Display) Screens Radiation - these screens are flatter, often appearing as panels. LCD screens are safer than CRTs. • Display...

...Magic in the Screen In the age of technology which we currently live, it would be unheard of to come across someone who did not own a television, a computer, and a mobile phone. With all kinds of electronics at our disposal, personal interactions have become less essential. A 2008 study conducted by Ball State University and sequent partners, found the average American spend eight and a half hours a day in front of a screen whether it be a TV, a computer or some other gadget. A paper published in “Biologist” stated in 2007 on a average a person would spend under 2.5 per day participating in face to face interactions. This means that the average person would spend a minimum of triple the amount of time staring at a screen then they would in face to face interaction. In the Poem ‘The Screen’ By Terrence Chiusano, the author provides an example of the memorizing affect screens have on people. The poem explain how during flights the passengers generally ignore the stewardess when she explains emergency procedures, except on one flight the author was on where they instead used a prerecorded version. The recorded version immediately captivated everyone’s attention. The author’s message is clearly stated as well as obviously depicted in his example, ‘the screen is magic’. His language is simple and straight forward as he does not to dress up his message to have it understood. Even in a situation where the information could potentially save the viewers life it is ignored when presented...

...digital channels buy as much as four to eight times more as those who simply interact with retailers through one channel,” according to Maginus digital marketing executive Amanda Mulquiney. ARTICLE HIGHLIGHTS: While retailers may consider showrooming to be a threat, the power of in-store Wi-Fi and displays shouldn’t be underestimated. M&S’s free next-day-delivery-to-store proposition has supported 54 percent of the orders placed or collected in-store since launch. What began as a marketing gag generated engagement about the Bloomingdales brand’s use of cool technology to create excitement about the Super Bowl. If that is the case, doesn't it make sense for retailers to use digital in-store, providing the types of devices with which omnichannel shoppers are already used to interacting with? While retailers may consider showrooming to be a threat, the power of in-store Wi-Fi and displays to enable consumers to access product information, reviews, and prices shouldn’t be underestimated. Let’s look at three examples of retailers innovating with digital technology to improve their in-store experience and drive engagement and sales. Marks & Spencer’s Digital Flagship Department Stores: M&S has been providing more ways to access products, including the introduction of new browse-and-order points, large digital screens that play catwalk videos to showcase products, and virtual makeover counters with facial recognition technology. Its new multichannel Home Hub maximizes store...

...It was early Saturday morning. I decided to text my friend to see if he wanted to go to breakfast. Seconds later I got a response; he would love to. When we got to Cracker Barrel, there was a gigantic crowd. So, we decided to wait, but the entire time we were waiting, my friend, instead of talking to me, just looked at his phone. I was infuriated. And if it wasn’t bad enough already, when we got to the table, he proceeded to look at his phone almost the entire time. This is becoming a major problem among teens, as well as adults. Just last week, I was at Chey’s and I look over to the table across from me, and both women were staring at their phones and were not saying a word to each other. Is this what we really want the dinner table to look...

...Emerging Touchscreen Technology Touchscreen displays are becoming more common than ever before. Almost every type of device you can buy has an option for touch screen; phones, computers, DVD players and also televisions. It is becoming more beneficial to use rather than the old fashion push in button. One of the many benefits of having a touch screen is that it is much more convenient for those with larger hands. Many cell phones that we used to carry had such small buttons; you would literally have to use your finger nails to press them in. Also, there would be complaints about buttons sticking, and breaking off, making them nearly impossible to use. According to the article Touch Screen vs. Tactile Controls, the only benefit the button has over touchscreen is that you won’t have as many smears on the screen. Even though the cost to have a touchscreen is almost double that of a push button, consumers seem to want to keep upgrading their devices, just to have the next best thing. And as more companies started to develop full touch screen cell phones, other devices were stepping up. Touchscreen Today The tablet is one of the most convenient devices you would want to own. Your tablet is like a mobile computer, like a laptop but a little more discreet and easy to carry. Unlike the laptop, a tablet can use 3G to connect to the internet from almost anywhere. A disadvantage of the tablet compared to a laptop, is the fact that you can’t use it in your lap, therefore...

...Chapter 2 : Many parents are under the belief that technology and gadgets are essential for a child's development, but can you go too far? How much time should a child spend in front of a screen is a question being asked not just by worried parents but psychologists, health organizations and even governments. Read an expert's guidelines for managing a child's screen time, and his warnings on the dangers of recreational screen time, especially before bedtime. A new TLF Panel survey conducted on behalf of kids clothing retailer Vertbaudet.co.uk found that four in five parents believe technology and gadgets are good for kids, aiding in their development. The study found that 37 percent of parents asked said that their child spent between one and two hours a day playing with tech gadgets, and 28 percent said between two- and three hours. Moreover, the study found that 38 percent of two- to five-year-olds own an Android tablet, and 32 percent own an iPad; almost a third (32 percent) of these kids also have a mobile phone. The reason behind all this gadget use: over a third of parents (35 percent) said they use tech gadgets to entertain their children because they are convenient, and nearly a quarter (23 percent) because they want their children to be tech-savvy. A 2015 survey of 1,000 British mothers of children aged 2 to 12 found that 85 percent of mums admit to using technology to keep the kids occupied while they get on with other activities.

...Upgrading Technologies: Creates a Real-Life Movie Going Experience May 8, 2012 Abstract AMC Theatres began upgrades in their theatre technologies in 2009. Their project objective was to gain status as the number one movie exhibition industry in the world. The scope of the project would upgrade all of their facilities to incorporate 3D technologies, premium viewing, and state-of-the-art sound systems. This project would immerse the movie viewer into a real-life experience, thereby enticing the viewer to return satisfied, and become a steady patron of the company. Their estimated timeline for completion on technology upgrades for its remaining theatres is 2014. AMC Theatres, which stands for American Multi-Cinema was founded in 1920 when a father and his two sons purchased the Regent theatre in Kansas City, Missouri. AMC is second only to Regal Theatres, as a leading global movie theatre chain. The company gives credit to one particular son named Stanley Durwood. He believed that playing a multiple selection of movies in one movie house would in-turn lead to more guests, and more profits. This simple idea revolutionized the movie exhibition industry and became a blueprint for the industry. The concept for the movie theatre was born. It is this kind of inspiration that has encouraged the AMC Corporation to introduce more industry firsts. AMC was looking for a way to bring in new customers and refresh old patron relationships. Movie sales had begun to slump in the...

...computer. Brief history of a monitor The video display terminal, or VDT, marked the early days of computer monitors. These VDTs included a screen and attached keyboard linked to a larger computer by a serial connection. Because VDTs required a connection to a larger computer, they were often referred to as "dumb terminals." Dumb terminals displayed text only in two colors, usually black and green. The Apple II and first game machines began using a television CRT. IBM's CRT The ssssst of its new PS/2 computer system. The display technology allowed for 256 different colors and 640 x 480 resolutions. Despite the appearance of newer display techniques, VGA has become a computer monitor standard. Indeed, the VGA may have become the impetus for the modern computer gaming industry as the increased color palette made graphics possible. Up to this point, computer displays were limited to text. RESEARCH Types of Monitors A cathode ray tube or CRT CRT technology, computer monitors continue to be referred to as "The Tube". A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates an entire screenful of images. A Liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome...
