SONY在CES 2013發表56" 4K OLED TV
Sony develops the World's First and Largest "56-inch 4K OLED TV"- Prototype to be exhibited at 2013 International CES -
Tokyo, Japan - January 8, 2013 - Sony Corporation ("Sony") announced today that it has developed the first 4K (3840 x 2160) OLED (organic light-emitting diode) televisions. To demonstrate its latest achievement, Sony will display a 56-inch prototype at The International Consumer Electronics Show in Las Vegas, Nevada.
The world's first and largest* 56-inch OLED TV achieves 4K resolution by using the latest oxide semiconductor TFTs and Sony's own 'Super Top Emission' technologies.
Up until now, in order to force light through the OLED layer, OLED TVs used low-temperature polysilicon (LTPS) thin-film transistors (TFTs). However, there were some challenges inherent in the manufacture of large OLED displays.
Using oxide semiconductor TFTs Sony has been able to produce this new larger display. The new OLED component's structure also incorporates Sony's own 'Super Top Emission' technology, which has been successfully incorporated in other products already introduced into the market. This 'Super Top Emission' technology has a high aperture ratio and enables light to be extracted efficiently from the structure's OLED layer. By combining two Sony developed technologies, Sony has been able to overcome some of these challenges.
This prototype delivers all of the features expected from OLED TVs, such as high contrast, brightness, rapid video image response time and rich images produced even at wide viewing angles, all packaged in a large 4K resolution panel.
The OLED panel used in this prototype 4K OLED TV on display at the exhibition was jointly developed with Taiwanese company AU Optronics Corporation (AUO).
Sony has long been actively involved in the product development and mass production of OLED displays. Beginning with the release of the world's first 11-inch OLED television in 2007, Sony went on to release 17" and 25" monitors for professional applications in 2011. On the research and development front, Sony has given presentations on the results of its research in process (manufacturing) technologies for mid and large-sized panels as well as presenting research findings on oxide semiconductor TFTs and flexible organic TFTs. Sony is also actively working on next-generation OLED technologies.
Sony will continue to research OLED technology with the goal of commercializing its new 4K OLED televisions, as well as launch 4K LCD TVs like the BRAVIAs exhibited at CES2013. From filming to editing, content creation, delivery, distribution and display devices, Sony is making its unique new 4K imaging experience available to users in a wide variety of ways.

之前以為SONY放棄OLED做CLED，現在突然又出4K OLED TV了，真的不知道SONY在想甚麼…… {:6_193:} 期待 唔知幾時會推出？{:6_209:} 我覺得55吋內睇1080已經好sharp, 我諗要60吋以上先可以發揮佢 本帖最後由 tinghai 於 2013-1-8 19:59 編輯
話明係prototype即係大家得個等字。仲有留意係呢隻OLEDprototype 係揾咗台灣AU Optronics幫手研發。最攪笑係當Sony CEO介紹部機時，部OLED TV出現了Microsoft 死機藍畫面（因為要用PC先出到4K內容做demo) 最後要當面reboot部PC，好攪野。{:1_253:}

反正都是項莊舞劍，意在沛公。
現在SONY是最主動推廣4K標準的公司，先不說4KTV，SONY一堆4K攝影機和生產線都已經準備好了。
其中一個4K標準的最大問題是現在根本沒有能夠滿足4K色域標準的4KTV，因此SONY必須帶頭展示4K未來的產品。
OLED有著比LCD更廣闊的色域，是未來4KTV其中一個相當有潛力的方案。
接下來那些專業人士才會漸漸把手上的影像生產器材轉到4K的。 OLED Is Better...{:6_193:}
