Sorry man,some part of the post just vanished,i meant are you talking just specification wise or you have compared the displays of these handsets in real life your self

i've compared them

With Nokia you can change font size in messages and phone book you can on mine anyway and with large font reading texts is so easy.

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.

You are right that an LCD panel consists of a thin layer of organic molecules that have the property of twisting the polarization plane direction of light. By an angle dependent of an electric field applied to it. When the molecules are placed between two polarizing glasses with their plane of polarization at right angle, the backlight will pass through with an intensity depending on the amount of angle twisting by the molecules.
Where you are wrong is when saying that a TFT is not an LCD. A TFT
IS an LCD. TFT describes how the active medium is submitted to the electric field, and the LCD is the active medium itself.
