No what is being said here (and in earlier threads) is a lot of speculation, and based on other OLED technologies that may or may not apply to the Sony OLED.
Apparently from what I read the OLED technology does 'wear out' (as do other display technologies like Plasma). I haven't seen any concrete numbers with regards to the Sony VZ90 display as to a usable lifetime.
My random guess/advice - don't keep the display on 24/7 (two years of continuous use would be bad I guess). | |

The current average is five years of continuous use and should rise as the technology matures.

| I don't still get that if oled screen don't need backlight, how hell you can see it in dark?

| Well from my limit knownledge of OLED's, the stuff inside each pixel is composed of organic molecules that phosphoresce when a stimulus is apply to them, much like the fish and jellfish that emitts light. They (fish etc..) do it with certain enzymes and chemicals, the OLED's emit light when a electric stimulus is applied to the individual pixels. Therefore you don't need a backlight.
Atl least that how I think it was suppose to work.  | |

This is why when you look at an OLED screen(like on the VZ-90), as opposed to a LCD with a backlight (like the TH-55), the VZ-90 has a black border, but the TH-55 has a white border around the 320x480 portion of the screen. The benefit of it is that an LCD backlight is always on, and the individual pixels have to block the light (this takes alot of power), but on the OLED, the only pixels that are lit are the ones that need to be. This accounts for the main decrease in power consumption for an OLED over an LCD.

Why is it that we cannot expand our screens to meet their real resolutions? But, I do see the benefit of an OLED Screen. That's really smart thinking. The image is acutally drawn out if you think of it that way.

Well, as far as I know, the VZ-90 doesnt access any extra pixels, but they are defaultly dark, so it doesnt need to. In otherwords, you cannot differentiate between the edge of the screen, and the edge of the accessed screen area. I would guess that the screen in a TH or UX is hardware limited to appear as a 320x480, and so there is no way to access the extra 2 pixels. Even if we could access the pixels, we would just darken them, which may cause a little bit of a battery hit (its over 3000 pixels).

OLED (organic light emitting diode) displays allow a highly detailed image
to be displayed in a very small amount of space. This is called a
microdisplay. OLEDs can be made using small-molecular weight organic
materials (SM-OLEDs) or polymer-based materials (PLEDs, LEPs).

| 2010 will have some cell phones with OLED screens via Samsung. Looks like Sony has abandoned making OLED Televisions that the had last year (too expensive and still not available in sizes as large as LCDs.
Sorry for not a well written note but maybe we can remove some of the spam at 1src some other method other than adding posts....

The VZ90 I have still has an amazing OLED screen in dark lighting conditions. It is funny reading this article which is like 7 years old and how people are talking about device lifetimes up to 5 years. Now, a device is not even used past 2 years. The world is backwards.

| I have to agree JAmerican. I have an old launch PSP that still plays perfectly. My UX (which, by the way, you saved me with that USB plug and play for the memory stick software) held up until I sold it to buy an iPhone. Big mistake. I hated the iPhone, switched to Android, and dislike Android. The clie's were ahead of their time and still serve purpose, I am looking into getting another UX or a VZ90 but I am worried about the Japanese translation of it. | |
