Good stuff, here's some info more general info about TFT's that I've copy/pasted from Wikipedia, dunno if you can incorporate it into your guide in any way:
TFT LCDs are a variant of liquid crystal display which use thin-film transistor technology to improve their image quality. TFT LCDs are one type of active matrix LCD, though this term is usually synonymous with them. They are used in both flat panel displays and projectors.
In computing, TFT monitors rapidly displaced competing CRT technology, and are commonly available in sizes from 15 to 23 inches. As of 2004, they are also rapidly displacing CRTs from the television market, although there they have other competitors, such as from plasma and rear projection displays.
Types
Basic consumer displays are of the type TN+Film, which is the lowest cost kind, yet it offers fast enough (8 to 16ms) framerates to allow playing games or watch DVD movies without shadow-trail artefacts. The TN displays suffer from limited field of view, especially in the vertical direction and most of them are unable to display the full 16.7 million colors available from modern VGA graphics cards. They can display up to 16.7 million colors using a dither method which quickly cycles pixels through a 6-bit pattern out of the available 256 colors each to simulate a given shade. The pattern generating algorithms are proprietary goods and good ones are quite hard to compile. About 10 to 15% of all people are able to see the dither cycling on TN screens and many of them are disturbed by the resulting checkered artifacts, making them unable to use such displays regularly.
A slightly more expensive type is known as MVA (Multi Vertical Alignment), which was originally developed by Fujitsu. They offer wider viewing angles and the problems caused by dither are less pronounced, with some able to display the full 16.7 million colors without dither. The trade off is a moderate loss in screen brightness, due to a more complex orientation of liquid crystal particles. MVA panels may not be fast enough for gaming and are less than ideal for showing multimedia content on LCD, because their response time is very large when switching between slightly different colours. MVA technology is only available to consumers in larger sized screens, and analysts consider MVA a technology without a bright future.
PVA (Patterned Vertical Alignment) type panels are of a more advanced version of MVA technology offered by Samsung. They are still less then ideal for gamers and photographic uses. Again, they are only available in larger sized screens.
The most expensive technology is "IPS" (In-Plane Switching), which produces high quality displays with true 16.7 million color depth and wide viewing angles to match CRT displays. Consequently IPS displays are well-suited for office work and presentation purposes, where up to three sitting and three standing persons can confortably watch a single screen. Their brightness is good, their contrast and color fidelity is excellent and most IPS screens are compatible with the advanced s-RGB colour management standard. Only the hardness of TFT color shades and grades prohibits their use at high-end computer graphics studios. The main drawback of IPS screens is their relatively slow response time of 25 to 40 ms, making them unsuitable for action gaming and fast-paced video. IPS technology only appears in larger displays aimed at professionals. They are sensitive to abuse, and the surface should never be touched.
Better still is S-IPS (Super-IPS), which has all the benefits of IPS technology but improved pixel refresh timing, enough for multimedia purposes and sometimes even action-packed gaming.
Display Industry
Due to the immense cost of building TFT producing factories, the number of OEM panel vendors probably does not exceed four or five major players. The raw LCD TFT panels are usually factory-sorted into three categories, with regards to the number of dead pixels, backlight even-ness and general product quality. Additionally, there may be up to +/- 2ms maximum refresh rate differences between individual panel that came off the same assembly line the same day! The poorest performing screens are then sold to no-name vendors or used in "value" TFT monitors (often marked with letter V behind the type number), the medium performers are incorporated in gamer-oriented or home office bound TFT displays (sometimes marked with the capital letter S) and the best screens are usually reserved for use in "professional" grade TFT monitors (usually marked with letter P or S after their type number).
Value edition TFT screens (the Vs) and most 15" sized LCDs usually fail to include a digital signal compatible DVI socket, thus their future-proofing may be limited. The upper end of 17" or 19" gamer and office TFT screens have dual analog-VGA and DVI sockets and almost all "P" professional screens have DVI and pivot mode for a 100% sized, full, vertical A4/Letter page display. However, the use of DVI video signal does not automatically guarantee better image quality. A video card with good RAMDAC, properly shielded analogoue VGA cable may offer the same on-screen experience. Indeed, sometimes vendors offer better panels in their non-DVI panels, due to overlapping model generation changes.
