松下的这个电视第一次亮相是在1月份的 CES 2016。只不过显示效果没这么好...不能做到完全透明...看来这半年终于做出了一个不错的demo，赶紧拿出来给大家看一下...
这次这个已经确定确实是OLED。
现在的状态是prototype，not available in at least 3years, Cost unknown! 意思就是现在是个试验品，大概2019年可以量产，成本未知...所以同学们，你们有三年时间攒钱...
LCD做透明显示有两个过不去的坎：一个是背光，需要导光板（磨砂）和反光板...一个是CF，杀光太厉害，只有特定波长光透过...
OLED其实本身就是半透明的，因为没有背光，基板透明，阳极一般用ITO透明..阴极一般用Ag，本身不透光，然而厚度在100nm以下是半透明...不需要CF，只是加个偏光片...
我以前做过的显示屏关态也可以看透...就是有点暗而且模糊...所以说能不能透明，应该是阴极材料厚度和电流（亮度）的trade off...至于他们用了什么牛逼的材料/工艺之类的，达到这么好的透明度...我就不知道了...
至于开态不透光...我没做过，不好评价。不过以现有的技术不难实现...液晶就可以做到...
另外，最牛逼的是柔性显示和透明显示结合在一起...一般常见于各种概念机...效果大概就是一层可以看电视的塑料纸...或者说，理论上可以做出能显示的 小雨衣...想想就excited...
有兴趣可以看一下：
另外，OLED和LCD科普的话可以看我另一个答案：http://www.zhihu.com/question/22263252/answer/41226589；里面废话多请忽略...
At first glance, it looks like a glass pane in a sliding door, but with a push of a button or wave of a hand a television screen instantly appears.
Panasonic has been improving its transparent television since unveiling it at the Consumer Electronics Show, with the goal of making it completely invisible.
The firm swapped out the LED screen for an OLED and now when in transparent mode, the set is completely undetectable - allowing users to clearly see through it.
An OLED screen uses self-lighting pixels, while an LED uses a backlight to illuminate its pixels.
The Japanese electronic maker's innovation was first seen at the Consumer Electronics Show (CES) this past January in Las Vegas Nevada.
Not only has Panasonic created an invisible set, the firm also improved the image to where it is ‘almost indistinguishable from existing televisions’.
The earlier prototype required a backlight to enhance the image on the screen but now, users can see a clear and bright picture without anything giving it a boost in the background.
To show off the improved model, the firm embedded the OLED screen, which is developed from fine mesh, into the glass sliding doors of a large entertainment center.
While not in use, consumers can see the vases and statues that sit behind it on the shelves.
The TV is still a prototype, and is unlikely to be available for at least three years, according to a Panasonic spokesperson. The cost is also unknown.
HOW TRANSPARENT SCREENS WORKOLED (organic light-emitting diode) screens produce light when electricity is applied through them.
They are used to create digital displays in devices such as TV screens, computer monitors, portable systems, handheld game consoles and smartphones.
This material does not need a backlight and filters, unlike LCD displays, which makes them more efficient, easier to make and much thinner.
It also means that they have the option to become transparent.
An OLED panel is made up of a layer of plastic sandwiched between two electrodes - the cathode and anode - all deposited on a glass substrate.
When electricity is fed through the plastic, it emits light on its own, which is why no backlight is needed.
As the name suggests, transparent OLED screens are made up only of transparent components (cathode, anode and substrate).When the panel is on, the self-illuminating pixels produce a picture, and when the screen is off, the components go back to being transparent.
The panel requires so little electricity that the panel can be incredibly thin, making it practically invisible.
Viewers looking at the 'invisible' screen on Panasonic's prototype up close would see that it is in fact a very fine grid.
OLEDs can also be designed to be more flexible and even rollable.
