not sure about this whole diode thing - was driving in north wales a couple of weeks back (fantastic walking in the mountains btw) and noticed all the traffic lights are those diode ones too,, like GoH said.
EXCEPT - the green light is blue!! 
Don't want all my phone colours messed up like that!!

I have seen information that TFT is brighter then TFD as well, but that info is very old...
[edit]
TFT is indeed sharper, and does use more power

actually, i think there IS a difference between thin film transistor and thin film diode.
over here in sg, our traffic lights used to be just coloured lights, which were not very visible in sunlight. soon, the government replaced all of those with diodes (ie, the lights are made up of small little diodes), making it very visible in both sunlight and at night.
i assume thin film diode works in the same concept.

I assume you did not have knowledge about Electronics and didn't know what is actually a "diode".
A diode is a simple 2-pin semiconductor and have polarity different. A diode is "open-circuit" (opened) initially, when the potentiate different across it reached a saturation point, it will then "close-circuit" (shorted) and allow current to pass through. Therefore, a diode act like an electronics switch.
The traffic light in singapore is using component known as "Light Emitting Diode (LED)", which will emit light when it is "close-circuit".
A Transistor is a more complex component which operates in 3-pin. It is similar to a two diodes with one of each diode's leg shorted together.
Therefore a transistor can use for much complex roles rather than only electronics switch.
So, "Thin film Transistor (TFT)" should be a better choice to "Thin film Diode (TFD)".

quoting the long quote in order to wonder why quoting the whole quote was necessary;
i assume that i just got my rear end flamed over an ASSUMPTION? i assume too that u didnt quite catch the "I THINK" in my words? i assume u supposed i was trying to act smart? well, no.

- "TFD (thin film diode) is a type of LCD (liquid crystal display) flat-panel display technology.
TFD technology combines the excellent image quility and fast response times of TFT, with the low power consumption and low cost of STN.
TFD technology is an active-matrix technology, meaning that a tiny circuit (a diode) is located next to each pixel, allowing the pixel to be turned on and off individually. This permits faster response time and greater contrast compared to passive-matrix technology."

Compared to other types of LCD technology, TFT features excellent image quality and response time, but uses more power, and is more expensive.

- "STN (Super Twisted Nematic) is a type of LCD (liquid crystal display) flat-panel display technology.
STN uses less power and is less costly than TFT technology, but at the expense of image quality and response time.
STN technology is a passive-matrix technology, meaning that each pixel must be "refreshed" individually many times each second. To accomplish this, the liquid crystal must react slowly enough to maintain state between refreshes. This keep response times relatively low, and limits brightness and contrast."

*bows to wrath*
Wow. So much tech info be4 I had my lunch!  need to study this again after lunch but I think I get it
@ masseur... erm, brekkie, some coffee and 1 cookie so far... erm... and the overall excitement that my work instills in me of course

Interesting stuff.
My brain is now 'Super Twisted', anyone else?
What are the new Sony laptop screens - they are nice.

The smilie does not show for me but I take it it's summat to do with Flaming.
Just be sure you didn't acciodentally take MY picture there!! (my name really is Flame) you don't know who you're messing with!!

After additional digging this is what I found.
In dark conditions the brightness of TFT and TFD is aproximatly the same
In light conditions there will be differences between different types TFT/TFD screens.
TFD will generally be able to perform better in bright light conditions due to the increased reflectivity which can be achieved because the need for backlight is diminished/gone.
For example, Epson TFD screen will be much brighter in light conditions then TFT because there is no backlight, and thus the screen reflectivity is 50%-60% as opposed to 20%-30%.
