La CES-ul de anul acesta au fost prezentate primele televizoare oled de mari dimensiuni (55-inches):

Se pare ca Samsung a avut cistig de cauza.

Le vom vedea pe piata in a 2-a jumatate a anului. La inceput la preturi mari dar preturile vor scadea vertiginos. Se pare ca plasma si lcd se indreapta catre linia de finish.

Ai dreptate, tot ce iese nou pe piata este cu LED.
Tehnologia OLED nu stiu ce va aduce, in afara de bullsheeturile marketing cu care toti ne-am obisnuit...

Calitatea imaginii la OLED este evident peste Plasma sau LCD-LED, nu este chestie de marketing.
Problema va consta in preturi, modelele de 55" prezentate vor avea un pret estimativ la 10 000 euro ...cine vrea sa faca o precomanda?
Preturile pot scade vertiginos in cativa ani, probabil 4-5 ani, asa ca nu stiu de ce ar reprezenta vreun interes actual pentru consumatori, sunt doar prototipuri de show.

Sony's Crystal LED joins Samsung and LG's OLED as 55-Inch Display Tech of the Future

LG, Samsung, and Sony showed off three very bright, very colorful, and slightly different HDTVs using new display technology.

A few years ago, OLED seemed like the next big thing in HDTVs, but then it fell by the wayside. Until this year, OLED displays haven't gone beyond small devices and $2,500 11-inch lamp-sized HDTVs. That is changing, with LG and Samsung showing off 55-inch OLED HDTVs that wear their OLED technology proudly, and with Sony's new Crystal LED technology, which doesn't quite use an OLED panel but works in a similar way.
Sony's new Crystal LED screen uses a similar concept, but without the organic aspect. The 16 million inorganic LEDs are arranged on a panel, and each lights up on its own, like OLED. According to Sony, this new technology offers 3.5 times better contrast, 1.4 times wider color, and 10 times faster response time compared to its current LCD panels.
Both Samsung and LG showed off as-yet-unnamed 55-inch OLED HDTVs at their booths on the CES floor. OLED, or organic light emitting diode, technology is a new color screen technology that differs from liquid crystal displays by actually having the pixels themselves light up. lLCD HDTVs, even LED-backlit ones, form a picture on the liquid crystal layer and must then be lit by LEDs on the edge or back, or by CCFL lights on the back. OLEDs take the backlight out of the equation, meaning when a pixel is "black," it's literally off; there is no light coming from that pixel. This means both the screen will show better black levels and consume less power.
I looked at all three screens, and I was impressed. All three models were incredibly thin and very bright. While I couldn't get as close to them as I would have liked, I looked at an OLED panel similar to LG's close up at LG Display (a different company, that provides LG and other manufacturers their panels) and under my sharp and blinking eye I saw no pixel lit in the black areas. They winked out, like the stars in the Doctor Who episodes "Turn Left," "The Pandora Opens," and "Logopolis." I know, technically, the last one is a serial.
Whether these claims are true will be seen when we put the new Crystal LED display, and the new OLED displays, under our scopes in the PCMag Labs. That won't happen for a while, though. Sony's Crystal LED display was strictly a prototype with no release date, and Samsung and LG's 55-inch OLED HDTVs aren't expected to see pricing or availability until the second half of this year.

Cel mai important este nivelul de negru, panourile OLED putand afisa negru absolut, pixelii avand starea de stins total spre deosebire de plasma sau LCD unde exista o lumina reziduala.
Astfel contrastul este infinit.
Culorile sunt mai intense si mai precise iar timpul de raspuns de sute ori mai bun.Asta inseamna ca imaginea este perfect sharp chiar si la miscari foarte rapide, televizoarele actuale au tendinta sa blureze sau sa introduca mizerii la miscare rapida indiferent cati Hz au la afisare.
Unghiul de privire nu are limite iar tratametul antireflexiv este foarte eficient nefiind limitat de un anume tip de suprafata(la plasma) sau de polarizarea de lumina(la LCD).

Daca nu ma insel mai au ceva foarte important, pixelul alb pe langa cele trei normale, verde, rosu si albastru.

Cei care au avut ocazia sa vada panouri OLED noi si mi-au povestit impresiile (eu am vazut doar ceva foarte mic la o fosta expo de acum vreo 2 ani) au spus ca nu suporta comparatie cu tot ce este acum, e dramatic superior si au ramas cu gura cascata.

si ceva despre LCD SHARP (de la CES 2012):
Sharp 8K Super Hi-Vision LCD, 4K TV and Freestyle wireless LCD HDTV hands-on:

We got a hint of Sharp's plans during its CES 2012 press conference two days ago, but really nothing can prepare you for the sight of the company's 7,680x4,320 resolution 85-inch Super Hi-Vision 8K LCD. No matter how close we got, we still couldn't see the pixels, and the video reels being demonstrated showed an almost unimaginable level of detail. The worst part of it was, seeing that first almost ruined the experience of checking out the ICC 4K demo at the other end of the booth. We can say this -- after seeing Super Hi-Vision there's really no going back. Make an appointment to see those 33MP broadcasts from the London Olympics now. Also a concept, but packed in a more conventional design, were Sharp's Aquos Freestyle LCDs. These featherweight flat-screens were also featured in the press conference, and pack wireless HD streaming inside capable of extending up to 98 feet. The 20-incher in the video above even has a battery good enough for two hours of completely wireless 1080p viewing. While Sharp called them concepts, the displays seemed incredibly polished, so check them out in the gallery below because you may see them on shelves someday.

La modul grosier OLED-ul functioneaza cam cum functionau tuburile catodice. Cu deosebirea ca fiecare celula in parte este un tub catodic. In plus fata de ce a spus puf curentul consumat este mult mai mic, sunt biodegradabile, folosesc materii prime care se gasesc, pot fi facute panouri oricit de mari, subtiri etc. Practic sunt fara rival la ora actuala la orice capitol. E posibil ca timpul obisnuit de 4-5 ani in care preturile sa devina accesibile sa se diminueze. Chiar daca se mentine orizontul de timp de 4-5 ani tot e un interval rezonabil. Nu de alta dar plasmele pe care le detinem mai tin fara probleme 4-5 ani.

Multumesc.
Inseamna ca ori iau o plasma de 50" (ca asta de 42" Full HD mi se pare deja mica) ori iau una 3D pentru urmatorii 2-3 ani... Cred ca prima varianta e mai buna...

Preturile au inceput sa fie competitive la Oled-uri.
Modelul de anul acesta de la LG varianta economica si la 55 de inchi.

http://www.cel.ro/televizoare-lcd-led/t ... oCW_jw_wcB

Din punctul meu de vedere o comparatie intre tehnologia QLED de la Samsung versus orice OLED este clar in defavaroarea QLED. Nu am inteles de ce Samsung nu au mers mai departe cu OLED-ul. Au avut un prototip competitiv. Mi se pare ca s-au faultat singuri.
