    I've noticed that all of the official literature regarding the Incredible describes the screen as WVGA OLED - not AMOLED. Can a screen be OLED without AM (active matrix) technology - and if so, what will the difference be between the Incredible's screen and the N1's AMOLED display?

    I haven't seen any "official" literature yet, so- if you provide a link so we can see for ourselves I and many others would be most appreciative.

    I also know many potential incredible owners will not buy anything without AMOLD screen. I am one of them.

    Please support claim.

    WVGA is Acronym for wide video graphics adapter (drivers/software) which decribes the resolution of the screen 480x pixel hieght with wider width.

    Has nothing to do with AMOLD screen.

    "There are two types of OLEDs used in displays - PMOLED and AMOLED. The difference is in the driving electronics - it can be either Passive Matrix (PM) or Active Matrix (AM).

    With Passive-Matrix OLEDs, the display is controlled by switching on rows and columns. When you turn on row number x and column number y, the pixel at the intersection is lit - and emits light. Each time you can choose just one pixel to light. So you have to turn these on and off very quickly. You do so in a certain sequence, and create the desired image. This is somewhat like the interlace-system used in old CRTs, but the control is done pixel-by-pixel.

    PMOLEDs are very easy and cheap to build, but they are limited to small sizes (up to 3", typically). The image displaying is a bit complicated (because of the row/column method). Also the power consumption is not as good as AMOLEDs.

    AMOLEDs have a different driver electronics - each pixel is controlled directly. AMOLEDs are more expensive, and much more difficult to create, but can be used for larger displays (current prototypes are up to 40") and are very power efficient.

    The first OLED products in the market used PMOLEDs - these were MP3 players, sub-displays on cellphones and radio decks for automobiles. The displays were small and usually with just one or two colors. When AMOLED panels started to emerge in 2007 and 2008 we have seen these larger displays in mobile video players, digital cameras, mobile phones main displays and even OLED TVs.

    Sorry about that I must have been writing my post right when you posted yours, I am using and iPhone. I guess we said the same thing!

    But it's nice to be able to show that the WVGA is how the GUI interacts with the AMOLD screen, and just to further express the point to Kdawg- - the op- AMOLD screen is simply what everyone has stated in their posts, it's a screen type, while WVGA is not a screen type but drivers for the screen to work.
