Until recently people were stuck with large clumsy CRT (Cathode ray tube) devises within their everyday life, within the space of a decade after their move to television screens LCD’s (Liquid Crystal displays) and plasma screens have made CRT Displays obsolete. In this article I will explain in detail how the basic physics of LCD technology and plasma works and compare the two and decide which one is better for your needs. The wide range of applications for LCD displays are used for is impressive; they include computer monitors, televisions, instrument panels and signage. Many Consumer devices such as video players, gaming devices, clocks, watches, calculators, and mobile phones have benefited from the unique Characteristics of LCD displays. They are available in a wider range of screen sizes than CRT and plasma displays and are the most popular display technology by far. Plasma screens have some advantages over LCD screens
Modern colour LCD screens work on a similar principle to monochrome LCD screen, the main difference is the configuration of the pixels and the source of the light. One pixel on an LCD screen is made of 3 sub pixels each of which is a primary colour but each sub pixel is activated by current passing through the through an electrode and changing properties of the liquid crystal. This type of LCD screen is made up of 7 layers the first of which is a fluorescent backlight differing from the mirror on the basic LCD, this allows for the screen to appear bright and to been seen well in a dark room. The screen consists of a mirror then a layer of polarized Film, a layer of liquid Crystals sandwiched between a positive and negative electrode/glass, another layer of polarised Film set perpendicular to the other piece of ...

...re vibrant colours. Some high end LCD screens can have refresh rates and viewing angles that a similar to plasma screens while keeping all of the benefits of the LCD screen. Lastly Plasma screens are less energy efficient and could overheat if not put in a well-ventilated area I think I good quality LCD screen would be the best choice for your home theater because the theater will be in an enclosed space so their will be no overheating problems. You will avoid problems like burn-i and shortened life span which a re problems which have hampered Plasma screens. Also by buying a high end LCD TV u will be avoiding all the problems that have hampered earlier LCD screens like slow refresh rates. If you buy a good LCD screen it should give the best overall experience because u will avoid the problems of plasma screens while minimizing the problems with LCD screens.
10. The main qualities to look for in an LCD monitor are price, size, brightness, contrast ratio and resolution.
According to Martin, C. (2011) the consumers have already experienced the first and second screen revolutions in the past decades and are now in the middle of the third screen revolution.
The strategy of the most advanced player in the niche market resulted in years of its market leadership in graphic projector sector of high-end industrial market. Barco Projection System (BPS) virtually enjoyed the fruit of its dedication on technologically superior projectors, however, the projector market encountered an unexpected (in light of BPS) new product 1270 "superdata" projector (1270) from Sony. Introduced at Siggraph trade show in 3rd quarter of 1989, 1270 showed its superiority in brightness, image quality, and resolution to the counter product of BPS.
Up until 1935, televisions were not electric as they are today. They were mechanical, powered by a small motor with a spinning disc and a neon lamp. The picture projected was very small, sometimes half the size of a business card, and only showed shades of orange and red. From 1935 up until World War II, the electric television was perfected and made ready for public distribution. The electric television provided a much larger, clearer screen with a full range of colors. In 1948-1949, during the post-WWII spending craze, the television became a must-have item for every American family, bringing a world of information and entertainment into living rooms across the country and changing the way Americans viewed many things.
The three different ways colored light can be produced in neon tubing is, 1) Clear glass tubing with neon produces a red or reddish-orange; Clear glass tubing with argon produces a faint purple. 2) Some colors are produced by inert gases in tubing with fluorescent powders painted or baked on the inside. 3) Coatings applied to the outside or inside of the gas can change the apparent color that one would see from a distance.
... viewing quality becomes and the more channels we can get, the more people are likely to stay inside. Don’t get me wrong, I love TV, and I feel that it is one of the most important inventions that this world has been blessed with; but I feel that it is taking away from some of the “realness” of our lives. People are becoming less healthy, they are developing eye and other health problems, and they don’t know what is real and what is not any more. I hope that in the future television designers and makers can develop so new technologies that would improve and not worsen our environment. The television is a very helpful and important tool that has had a great impact on our society, but we need to be aware of how this tool has also affected out environment as well, so next time you watch you television, think about what impact you might be having on our environment!

Most people did not purchase one until the 1960's. In 1980 there was a rise in home video. Many of us began to tape shows, then we were able to choose what and when we wanted to watch it.
We even now have watches that act like a phone and have most of the qualities that a phone does, or at least the iphone. In 1970 they had block phones and black, grey, and white tv’s.

Chroma Key, also called Chroma Keying, Color Keying, Color Selection Overlay or, more commonly, green screen and blue screen, is a very innovative tool for special effects used in the post-production of a movie. Along with the technological advancements, this tool can now be used by anyone, without needing expensive equipment. The process consists of layering two images, in most cases one of them being

I have been waiting for such a perfect opportunity to purchase my dream computer; the MacBook Pro, manufactured by Apple that weighs 2.02 kg. Getting the right specification was the breakthrough because, even more, my desire for the 15-inch laptop computer. The 15-inch computer has over 5 million pixels, which gives it a stunning look, with images taking a new level of pragmatism. It has an impressive 2880-by-1880 resolution that enables the eyes to view more of high-resolution images. Besides, it has a Retina display , which minimizes glare, maintaining an incredible quality and color. As a result, the high contrast ratio makes black images look blacker while white images look whiter. The inclusive IPS technology allows the user to view everything on the screen at a 178-degrees angle.
