TFT is a type of LCD screen that uses thin film transistor (TFT) technology. Each pixel is controlled from 1 to 4 transistors, giving TFT screens the best resolution of all flat-panel displays. and WXGA basically means wide screen!
Hope this helps - sorry i sound like a geek! I'm not really! lol.
Oh and the TFT bit just means it's a liquid crystal display (as opposed to a cathode ray tube or plasma) At one time they were called TFT to distinguish them from other types of LCD, but nowadays just about all monitor LCDs are TFT
