TFT = Thin Film Transistor and is a subset of the LCD display classification (Liquid Crystal Display)
Early LCDs were non backlit, "supertwist" displays, that were little more than a large calculator display in a matrix form instead of the figure 8 that calculators use.
As technology improved they moved to colour, and "Dual scan" technology" (Also had another name that escapes me)
Leter the "TFT" was developed that provided better colour rendition, lower power usage for battery operated units which became the norm.
The next gereration will likely be O.L.E.D. displays, Organid Light Emiting Diodes, that use NO backlight, and instead each pixel will glow or not glow according to controller. With TFT entire display glows, but "black" areas have the crystals set to opaque to stop light coming out.

Thin Film Transistor layer. this is a piece of tech that was added to LCD a few years ago: its another layer of electronics sandwhiched into the screen that better transmits electric current to the screens array of pixels, and it retains the charge of the pixels better and longer between screen refreshes (as part of its function is to store the charge in micro-capacitors, if memory serves well)
the ultimate effect of all that is you no longer get 'ghosting' from your mouse movements (big problem that almost ruined the reputation of LCD) and your refresh rates and such are way better.
but yes for a more technical explanation please see wikipedia or (where I learned about LCDs for my college course) visit howstuffworks.com

T.F.T. means "Thin Film Transistor "
