日本开发出长期稳定发光的iOLED        2013-05-21 09:01:04 来源：CBSi中国•PChome 作者：叶迎森 浏览：18次        
    NHK(NHK是日本唯一的公共广播电视机构)将展示iOLED技术，并且在单一的网络频率上向地面传送8K超级高清晰电视画面的试验。
    NHK与日本接媒共同在基板上成功开发了能够长期稳定发光的iOLED，过去的OLED的基板上的阳极、有机层、电子注入层、阴极层顺序做成膜，在经过一段时间从阴阳两极注入氧和水分子，使之恶化缩短寿命。
    由于受到氧和水分子的影响，电子注入层的开发受到影响。并且使阴极材料劣化。此次NHK实现了积成膜那样反转阳极和阴极的位置构造，带来长期稳定的发光iOLED，据说能够在阴极上做积层膜，彻底解决了劣化的问题。
    以前的通常的OLED在大气中放上100天发光就会减半，而iOLED确定不会出现这种情况。

阴极在我学到的知识中只能用活泼金属，因此很容易氧化。
ITO是典型的阳极材料。
这次NHK实现了在阴极使用ITO，完全颠覆了我所学的知识。:victory::victory::victory:

一个星期后等着他们来揭示谜底{:soso_e102:}

真好笑 日本广播协会变成电子企业了

呵呵！！看来OLED还处于探索与发展阶段，离投入消费领域还有段时间，许大仙您就继续在“盗梦空间”里等吧！！！[s:14][s:14][s:30]

NHK Makes Major OLED Advancement by



One of the major problems that has held OLED manufacturing back at large scales is the need for the panels to be literally perfect. If they are not properly sealed, the panels degrade quickly, losing half their brightness in under four months. Researchers at NHK think they’ve found the solution: By inverting the anode and cathode layers,and putting in additional shielding, they can retain brightness and prevent oxidation.
OLED yield has been a major factor keeping the technology that many consumer electronics manufacturers see as the future of display panels at bay, despite the number of technological advantages. Boasting self-illuminating pixels, great contrast, deep color, and no need for backlighting, OLED panels will not only will be cheaper to produce in the long run (once economy of scale kicks in), but provide a much higher quality product at low price points once production costs match LCD.
NHK is expected to talk more about its new “i(neverse)OLED” at DisplayWeek next week.

NHK has a theoretical fix for OLED's theoretical longevity problem

Japan's National Broadcasting Corporation, NHK, reckons OLED displays don't last long enough. And they have a point, because OLED pixels that are exposed to the air can lose half of their brightness in just 100 days. Commercial products are of course protected from the elements, but they're not perfect. This is where iOLED comes in. NHK inverts the anode and cathode layers in traditional OLED configurations, hence the added "i", and then adds an additional protective coating above the cathode. The result is a display that retains its brightness even when not fully sealed from the environment. Hopefully, this sort of solution will make its way into OLED TVs by the time OLED TVs are actually affordable, but in the meantime we're expecting to hear more about NHK's technology (and maybe see it in action) at Display Week later this month.

100天发光就会减半，那OLED的寿命也就2年左右啰，看来5年内是见不到普及了。

智商还是一贯的令人拙计

半岛之南

我们国家有没有企业研发OLED呢？
