Sharp to develop OLED mass production technology by 2016

According to Japan Economic Newswire, Sharp decided to launch a three-year project to develop OLED mass production technologies. Sharp's mass production technology will be ready by 2016 and then the company will decide whether they will build their own OLED fab or outsource the production to other makers or even license or sell the technology. It's not clear whether Sharp aims to make OLEDs for mobile displays, flexible OLEDs or OLED TV panels.

According to JEN Sharp will release its 3-year business plan on May 14, and then we'll know whether the OLED project is indeed included in their plan. The report says that Sharp plans to use "unique materials" that will make "clearer OLED images". Perhaps they mean SEL's and Sharp's new crystal structure innovation, used in the company's latest OLED prototypes.

This is a major change for Sharp, which since 2009 made it clear that they are not going to develop OLED panels. The company did show two oxide-TFT (IGZO) based OLED panel prototypes at SID 2012 (a WRGB 13.5" QFHD 326 ppi panel and a 3.4" 540x960 flexible panel), but they haven't made any public commitment to OLEDs yet. This is great news for the OLED industry as Sharp has always been a major OLED proponent.

夏普坚持在OLED上使用IGZO，到底是想卖IGZO技术，还是自己的LTPS技术不到家？CGS作为LTPS制作工艺中的佼佼者，在SHARP手中的表现却不如较低等级的ELA，SHARP到底是怎么了？

Towards SID 2013: AUO developed a 65" direct-emission OLED panel, more updates

SID 2013, the world's most prominent display conference will take place next month (May 19, in Vancouver, Canada) - and they now published some technical papars that will be discussed during the conference. And there's some interesting stuff in there.

First up is AU Optronics paper, describing how the company developed the world's largest OLED panel: a 65" direct-emission Oxide TFT one. This panel, that was produced using an FMM process, features a long-range threshold voltage uniformity of 0.34 V, and the dam and fill encapsulation process is simple and highly stable.

AUO is still struggling with small OLED panel production, but it seems to be advancing nicely on its large-panel production technology. The company produced the 56" substrates for the Sony and Panasonic 56" 4K2K OLED prototypes unveiled at CES 2013.

There are many interesting papers to look for during SID from Samsung, LGD, Fraunhofer, Toshiba, Plextronics, DuPont, SEL and others describing recent advances in OLED technology. Two noteworthy papers will be The University of Florida's update on recent developments of their CN-VOLET (Carbon Nanotube Vertical OLET) technology, and BOE's paper on their 17" ink-jet printing OLED panel.

有个地方要纠正一下，AUO在此次和sony合作的56寸4k OLED面板里，到底有没有制作这个Oxide TFT基板还是未知数，sony之前和toshiba有展出过自己的ITZO技术，不过当时展出的是3寸VGA分辨率的OLED小屏幕，大屏幕方面的应用为止
