TFT: Thin Film Transistor: LCD panel. A type of LCD flat panel display screen in which each pixel is controlled by one to four transistors. The TFT technology provides the best resolution and quality of all the flat panel techniques, but it is also the most expensive.
TFD: Thin Film Diode: Darker picture and less quality than TFT, but consumes less power overall. Not available in larger resolutions due to huge cost in volved.
UBC: well, the only possible results I had for that from a google dictionary search were: Used Beverage Containers; University of British Columbia; and the Uniform Building Code. I have never heard of any UBC screen technology.
Overall, as far as I am aware, TFT provides the best balance between quality, price, and power consumption from the ones you've listed, although LCD is better than TFT.

UFB is Ultra Fine and Bright,which was introduced by samsung few years ago.Main advantage being,the power consumption was much lower comparable TFT's..

But why when I compared (used to be) my K600 and W800 I found that the screen of K600 is better and brighter than W800? W800's screen is a little bit yellowish I think.
PS: I compared in the same brightness level.

TFD being lower quality why has SE put those type of displays in K550i & W660i. Surely these phones are on the same quality level as K750i & W600i in the past so why put in lower quality display. I just find it odd. I know it increases battery life but i would rather have better display. Anyway just a thought.

my understanding is that up to 65k colours tfd and tft are equal in all respects except tfd is cheaper to manufacture. higher that 65k colours then TFT is both brighter and cheaper to manufacture
I recall that the Z600 was first SE to have TFD and its csreen was the best at the time, even better than T610/T630 (having had all three myself)

UBC is Ultra Bright Colours. And I have a feeling that it is somewhat similar to Stereo Widening, but for pictures.
