    End of 2004 (as I've read somewhere) and still TFT displays - isn't that a shame, really?

    You'd think that OLEDs/polymer displays would be ready for the mass market some time - especially for the small display sizes required for handheld devices. Aren't they already used for displaying data in some automobiles and cell phones?

    OLED so far haven't really offered anything significant over TFT LCD so why would it be used?

    Kodak has a camera (cameras?) with a small colour OLED display. Lots of cell phones use them. Cheap ones are all over the place (elevators, kitchen appliances, car stereos, that kinda thing). I don't think I've ever seen an OLED display bigger than an inch or two though.

    Afaik, there are still some problems with OLEDs. Like low lifetime of blue (IIRC) and poorer colour reproduction/stability. Depending on technology it might also draw more power than TFTs.

    To me it would seem a little premature to decide on OLEDs.

    The rest of the list is also mass market technology (more or less), why should the display be any different?

    I just thought about the advantages that are usually listed when predicting the future of polymer displays:

    - Potentially higher resolutions possible
    - Potentially cheaper to manufacture than TFTs
    - no backlight necessary and thus lower energy consumption and higher battery life.

    I don't know much of the state of that technology, though.

    Not to mention that OLED have much faster switching, which would be a significant advantage for a 3D gaming device.
    Still, it might not be ready for prime time by next christmas.

    I think the OLED industry people are saying that bigger displays will be available in more substantial quantities in 4-5 years time.

    For a portable device, a flexible (roll-up) display is a must. :D

    PSP

    I think it be great its faster then current Ps2 and offers T and L on it faster at that for rendering plus CG instructuins to creata more life like games ofr the Ps2 bases i think its great tho still onlt 45mhz faster then the Ps2 its faster witch counts.
