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.

LCD is better than TFT.
isnt TFT a type of LCD?
AFAIK that is just a common misconception. With TFT, each pixel is controlled by between 1 and 4 transistors (hence Thin-Film-Transistor). However, with LCD there are 2 polarising panels, with a thin film of liquid crystal sandwiched inbetween. When voltage is applied to certain areas (pixels) of the polarising panels, the crystal is darkened. A light source then transmits light through the panel, and the darkened crystal partially/mainly blocks the light to produce the colours. Hence why you rarely see LCD on mobile phones. (as far as I know, anyway. Thats my interpretation of what I've read)
I agree with the comparison shots too. It would be good to see the actual differences on small screens considering its usually only larger panels that are compared.

Actually TFD screen is as better as TFT. Here some extracts from Mobile review:
1. Review of W610
For the mid-range phone, the company is not planning on going into QVGA-displays just now, which are the attributes of senior models like Sony Ericsson W850i. Even though a 176x220 pixels screen here is not particularly a relic, the handset doesn’t get any benefits from it (for example Nokia 6233 falling considerably shot of the W610i functionality-wise, shows off a much superior display, which equals the odds). Having a diagonal of 1.9 inches (31x40 mm) it shows up to 262 K colors (TFT). The first thing that catches your eyes at the first glance is how big the font size is – bulgy menu items captions is what makes the W610i look different compared to the more advanced models. Reading texts with this handset is a breeze, and the credit here goes to the display itself and its fonts. The screen can accommodate up to 6 text and 3 service lines. Unlike some other offerings, the W610i’s display doesn’t enjoy a protective layer that would guard it from sunlight, however in the sun picture remains visible, even though the colors appear washed out. Maybe they have applied a new finishing technology that makes for better visual experience.
They even said it was TFT
2. Review of K550
Having a diagonal of 1.9 inches (31x40 mm) the K550i’s display shows up to 262 K colors (TFT). The first thing that catches your eyes at the first glance is how big the font size is – bulgy menu items captions is what makes the K550i look different compared to the more advanced models. Reading texts with this handset is a breeze, and the credit here goes to the display itself and its fonts. The screen can accommodate up to 6 text and 3 service lines. Unlike some other offerings, the K550i’s display doesn’t enjoy a protective layer that would guard it from sunlight, however in the sun picture remains visible, even though the colors appear washed out. Maybe they have applied a new finishing technology that makes for better visual experience.
3. GSM Arena review of K550
The Sony Ericsson K550 display is made using the TFD (thin film diode) technology. It offers TFT-like image quality but consumes far less power as low as the now obsolete STN displays which were used in the first days of the color mobile displays.
So, there's no difference between TFT and TFD. They're even confused with each other. Just check the gsm arena page for K610:
http://www.gsmarena.com/sony_ericsson_k610-1431.php
It says it has a TFT, and in fact it has a TFD
To sum up, don't make a huge deal about it

Yes man.totally agree.but samsung display seems more vivid,so leaves a better impression.although they do it on expense of excess battery usage.where as nokia displays use less battery.so battery life with a lit display is longer for nokia.what you say?
