	Liquid crystal display - Biocrawler (Site not responding. Last check: 2007-10-21)
		A Liquid Crystal Display, or LCD, is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector.
		This type of display is called a passive matrix because the pixel must retain its state between refreshes without the benefit of a steady electrical charge.
		For high-resolution color displays such as modern LCD computer monitors and televisions, an active-matrix structure is used.

	CRT display technology (Site not responding. Last check: 2007-10-21)
		CRT displays are old technology but still widely used; however such displays are rapidly being replaced by the newer and more performant LCD displays, but they will still be in use in some areas for the years to come.
		CRT displays are heavy, difficult to move, they need a lot of space on your desktop, they can be noisy (some of them may generate high pitch noises) and they do emit heavy magnetic fields that can be very dangerous for health.
		But again, CRT display screens are still to be in use for at least a few years from now on, however their number is supposed to continously be reduced as time goes by.

	Computer display - Facts, Information, and Encyclopedia Reference article
		A computer display, monitor or screen is a computer peripheral device capable of showing still or moving images generated by a computer and processed by a graphics card.
		The sharpness of a display is described by its dot pitch.
		Some display technologies (especially LCD) have an inherent misregistration of the colour planes, that is, the centers of the red, green, and blue dots do not line up perfectly.

	DLP - Biocrawler (Site not responding. Last check: 2007-10-21)
		DLP was originally developed by Texas Instruments, and they remain the sole manufacturer of such technology, though many licensees market products based on their chipsets.
		The DMD chip is synchronized with the rotating motion of the color wheel so that the green component is displayed on the DMD when the green section of the color wheel is in front of the lamp.
		The red, green, and blue images are thus displayed sequentially at a sufficiently high rate that the observer sees the composite "full color" image.

	Display Technology Shoot-Out: Part II ExtremeTech - Find Articles
		By comparing a top-performing model in each technology, we are in effect examining the state of the art for that technology.
		The central concept for this article was to carefully set up, test, and evaluate all of the display technologies at the same time under identical conditions and procedures, using advanced instrumentation where appropriate.
		While each display technology has its own native gray scale, known as the transfer characteristic of the display device, signal processing electronics within the display modifies this to produce the gray scale we actually see (and measure).

	Comparison of display technology - Wikipedia, the free encyclopedia
		This is a comparison of various properties of different display technologies.
		Different display technologies have vastly different temporal characteristics, leading to claimed perceptual differences for motion, flicker etc.
		LCD have a constant (backlit) image, where the intensity is varied by blocking the light shining through the panel.

	Display Technology Comparison
		There are two reasons for this: each new technology had to mimic the dominant CRT in order to be accepted in the marketplace; and second, the image and picture quality delivered by the best CRTs was simply outstanding and untouchable by any of the new technologies.
		Most of the comparisons are based on the in-depth and comprehensive testing and analysis that we performed in the Display Technology Shoot-Out series.
		The new display technologies have now moved out from under the shadow of the CRT to stand on their own accomplishments.

		To form a display, or image, on the screen, the electron beam is deflected in the vertical and horizontal directions either by the electrostatic effect of electrodes within the tube or by magnetic fields produced by coils located around the neck of the tube.
		For displays meant to be photographed, the the deep blue trace of P11 phosphor is sometimes chosen while for extremely slow displays, very-long persistence phosphors such as P7 produce an amber or yellow afterimage.
		Vector displays for computers did not noticeably suffer the display artifacts of aliasing and pixelization, but were limited in that they could display only a shape's outline (with, in advanced vector systems, a limited amount of solid-tone shading), and only a very small amount of rather largely-drawn text.

		A low-power flat-panel display used in many laptop computers, calculators and digital watches, made up of a liquid crystal that is sandwiched between layers of glass or plastic and becomes opaque when electric current passes through it.
		While CRTs are capable of displaying multiple video resolutions without introducing artifacts, LCD displays produce crisp images only in their "native resolution" and fractions of that native resolution.
		LCD displays generally have a lower contrast ratio than that on a plasma display or CRT.

	Comparison: LEDCorp and Technology Associates LED flashlights
		It's the only torch (USAnians please note - "torch" is Commonwealth-speak for "flashlight") that lets you turn a three-in-the-morning pad to the bathroom into a Disco Inferno experience, at the touch of a button.
		Technology Associates' LED flashlights have more functions than the LEDCorp ones, and a higher price.
		Which is generally a good thing, unless you don't want the security guards to see you sneaking towards the display case.

		The EL display earned its credentials in demanding environments, such as medical instrumentation, rugged industrial settings, and military jet cockpits, where a display must be instantly readable at all costs.
		The EL display, with its exceptional brightness and temperature tolerance, is the preferred solution for ADC applications in variable temperature and lighting conditions.
		Probably because the display did not have sufficient contrast to be readable at a glance.

	Rental and Staging Systems - LED Down the Garden Path
		Now that LED technology has replaced projection cubes as the favored video wall technology, the business model has changed, as well as the technical reasons for selecting LED displays over other display technologies.
		In stark comparison, LED display technology for the rental market has already changed significantly in the short time the equipment has been available.
		This equation benefits from the electronic and mechanical reliability that is inherent in LED display systems, so that while there may be an obsolescence factor looming, the actual components should be able to remain working for a long time before being relegated to the trash heap.

	Display device - Wikipedia, the free encyclopedia
		A display device, also known as an information display is a device for visual or tactile presentation of images (including text) acquired, stored, or transmitted in various forms.
		While most common displays are designed to present information dynamically in a visual medium, tactile displays, usually intended for the blind or visually impaired, use mechanical parts to dynamically update a tactile image (usually of text) so that the image may be felt by the fingers.
		They are called segment displays, because they are composed of several segments that switch on and off to give appearance of desired glyph.

	Plasma - Plasma Display
		The plasma display panel was invented at the University of Illinois at Urbana-Champaign by Donald Bitzer and H. Gene Slottow in 1964 for the PLATO.
		Plasma displays are bright (1000 lux or higher for the module), have a wide color gamut, and can be produced in fairly large sizes, up to 260 cm (102 inches) diagonally.
		Because many plasma displays still have a lower resolution the image quality is often not quite up to the standards of good LCD displays or cathode ray tube sets, but it certainly meets most people's expectations.

	LCoS Display Technology Shootout Part A - ExtremeTech Discussions
		LCoS Display Technology Shootout Part A Posted: 02-01-2006, 3:09 AM Liquid Crystal on Silicon, LCoS, is a relatively new and obscure display technology that is now making its grand entrance into the HDTV marketplace.
		While LCoS is cool technology that will hopefully drive the prices down of large Hi-Def sets and for once match Plasma in terms of dynamic range, the truth is that these displays aren't dealing with source material with enough native resolution to make a difference.
		It's also true that unless the source material is superb, and signal quality is superb (and all digital) a good fraction of the differences between the display technologies and between 1280x720 and 1920x1080 native resolutions are lost in the noise.

	Overview of LCOS technology
		It is a reflective technology that uses liquid crystals instead of individual mirrors.
		The primary weakness of LCOS technology is contrast.
		For example, those familiar with the recent Texas Instruments study that highlighted a particular failure mode in LCD are aware that LCD panels may eventually degrade over the long run due to a breakdown of organic compounds used in their construction.
