[This is going way off topic, I am not following these much as of now, but oled and amoled are similar but not same, sony was the first to have oled tvs commercially avialable, and they heavily invested in oled but then stopped to focus on lcd(due to losses and high prices), the next focus for sony is crystal lcd and whitemagic. Crystal lcd seems to be the route sony will take with bravia line instead of amoled, until oled further evolves/gets cheaper to produce. Atleast thats the picture i get from when i was following.

Also, if you check out samsung's 55inch oled tv announced at ces 2012, they mention super oled and not super amoled hd + etc for it.]

I already know this, Active Matrix IS NOT a part of OLED technique it use in Oled technique, read my post again please i get the feeling you won't understand my post before you call somebody stupid BOY!!! And AMoled is not (oxide)-TFT technology.

An AMOLED display consists of OLED pixels that are (embedded in a thin film transistor) (TFT) that call men TFT array.
So, Active Matrix can use in Oled and is not 100% Oled technique.

I rest my case.

That's what i already mention why Sony invest Crystal led technique to compete AMoled SAMoled TV from Samsung and LG Because Sony is still develop Oled technique without a Active Matrix.

OMG! Can someone put some sense into worf1000's mind! If an OLED screen is not using active matrix as addressing scheme, then it is using a passive matrix one! The structure that you are talking about is the simplest OLED screen which is from a PMOLED model. The purpose of that structure is just to show OLED technology works. Do you even understand how OLED works? Why is it hard for you to grasp this idea?

Let's define what an addressing scheme is and how important it is to a display screen. It is to set (or maintain) the state of a pixel to either black/white or, more commonly, a gray-scale level. So without the addressing scheme, a display screen will not be able to show pixels properly. That's why any display screen have addressing scheme. The most common and practical is the Matrix addressing (active and passive matrix). The other two types which are direct and raster addressing are not being used in OLED. So how can an OLED screen display pixel properly without an addressing scheme as you keep on insisting about pure OLED technique?



You just said it yourself but still can't grasp the idea behind OLED. AMOLED uses TFT to eliminate higher voltage which is required for PMOLED operation. So this solidify my point that OLED screens can either use passive matrix or active matrix to operate and that AMOLED or PMOLED use 100% OLED technique (according to your own understanding). OLED is just a general term like LCD. OLED can come in different variation but it is still OLED. There is no such thing as pure technique or whatsoever because every OLED screen use the common structures to make up one, or else it cannot not be an OLED. OLED whether a passive matrix or active matrix are all 100% OLED screen.

Whichever OLED screen that uses TFT backplane is considered an AMOLED screen. Ergo, ipso facto, case closed. Q.E.D. In the Oxide-TFT case, the silicon is replaced with amorphous indium-gallium-zinc-oxide (a-IGZO) as semiconducting layer of the TFT backplane. Since it uses backplane, it is an AMOLED screen. OK!

Please read this:
SID, the display industry’s leading annual academic conference, is always a great source of information on R&D into future display technologies. Crystallization of a-Si to p-Si and its application to AMOLED fabrication have been a favorite topic of the symposium for several years now. However, looking over the proceedings of this year’s recently held conference, there anecdotally seems to be shift in focus; I could only find one paper on LTPS crystallization for AMOLED backplanes. Instead, a variety of papers promote using oxide semiconductors as a panacea to technical and cost issues that continue to restrict the growth of the AMOLED industry.

Samsung SDI’s development of a 12.1″ WXGA AMOLED (see Figure 1) highlighted the potential of this technology. The company used amorphous indium-gallium-zinc-oxide (a-IGZO) to replace silicon as the semiconducting layer of the TFT backplane

Proof that SONY OLED is AMOLED:

It is still relevant as I am also giving you guys info about the new AMOLED screen that Hayabusha might be sporting.

Have you not heard that Sony is going to release OLED TV in 2013?



The reason why is that Samsung Super AMOLED has a different structure than Super OLED. Although both AMOLED displays, Super AMOLED uses the Inverted OLED structure as oppose to the Stacked OLEDs one (I think) being used on Super OLED screen. IF you look at the photo that I posted above, it says there TOP-GATE TFT which means a transparent or semi-transparent top electrode exists emitting light directly. That's another type of structure that is being used to make an OLED screen. As I have always pointed out, there are many ways to make an OLED screen but it always includes an adressing schemes (active or passive matrix but very often active).

I think that's enough about the actual tech of the screens in upcoming Sonys.

Almost all modern smartphones' screens are clear and bright enough for most people. I bet many in this forum can't tell at first glance what tech is used in any given smartphone and we here are supposedly those in the know and are the first adopters of technology. You can tell that most screens are of acceptable standard by the fact that 9/10 reviews of new phones don't complain about the screen. On top of that who makes their phone purchased based completely on the screen tech implemented? Camera quality people do, video quality yes, overall design yes, screen size maybe, CPU cores maybe, RAM even maybe some but screen tech? No-one.

If it takes several pages of arguments to find any clarity between the techs then there is a lot of confusion between them, there is confusion because there really isn't that much real life tangible (not enough difference for people to care), maybe viewing angles but that's it. Now if one of the techs could boast battery life that's twice as long or suddenly be produced for 1/10th of the price of the other or could be produced with no border and

@rss_ndrsn

Just a small correction. Sony will release OLED Tvs in 2013 and Passive 3D TVs not Passive OLED Tvs. They have already started selling passive 3D Bravia Tvs in China since past two months.

I actually do not get what you are trying to say but my only concern is to make worf1000 understand that it is almost impossible (all things considered) to have a high resolution OLED screen without using active-matrix addressing scheme, and to correct his wrong beliefs about the AMOLED like not using "pure OLED technique", PS Vita screen is 100% OLED (lol..can't help but to laugh everytime I hear it), etc. I could not care less what OLED technology that the next Sony smartphone will have.
