I'm sure they'll ship one, but the idea here is that OLED is a little bit dimmer than it needs to be because it has to shine the light through a filter.

我确信他们未来会推产品，但是个概念需要的OLED要暗一些，因为它必须透过一个滤光片。

There is only one way to safely look directly at the sun when it is partially eclipsed, and that is through a special solar filter.

日偏食时，只有一种方法能安全地直视太阳，就是通过特殊的太阳滤光片。

Viewing it through a camera, binoculars, or telescope, without making use of a special filter for the sun can cause severe eye injury, experts say.

专家说，通过相机、双筒（即）看太阳，而不使用特殊的太阳滤光片，可能会导致严重的眼睛损伤。

The key is the smartphone's camera and processing power combined with the lenses and filters located in the cradle.

该技术的关键在于把智能手机的摄像头和处理能力，以及支架中的透和滤光片整合起来。

Solar filters can be handheld or in the form of 'eclipse glasses'.

太阳滤光片可以用手拿，也可以制成日食眼。

But quantum dots can make color without a filter, and so they could be much, much brighter.

但是量子点可以在没有滤光片的情况下显色，所以可以变得更亮。

Except during totality, do not look at the sun through a camera, binoculars, or a telescope, even if you are using a solar filter.

除了日全食期间，不要用相机、双筒、单筒看太阳，即使你正用着太阳滤光片。

Be sure whatever filter you select is ISO certified, and check to make sure they are not scratched or damaged before use.

不管你选的什么滤光片，要确保是ISO认证，使用前检查一下，确保没有刮痕，没有损坏。

For those without solar filters, there are simple indirect viewing methods you can use to track the progress of the eclipse towards totality.

没有滤光片，也有简单的间接观赏方法可以显现日全食现的过程。

These devices concentrate the sun's rays and can seriously damage your filter and your eyes.

些设备能够聚光，从而严重伤害你的滤光片和眼睛。

If you don't have these filters you can still observe the eclipse by making a pinhole camera using materials from around your home.

如果你没有滤光片，你可以选择使用针孔摄像机，用一些家周围的材料就可以制作。

In order to see any evidence of the separation, one thing you could do is pass it all through a second linear polarizing filter.

为了看到任何分离的证据，你可以将其全部通过第二个线性偏振滤光片。

This oscillation is important, because you can limit what light passes through a filter, depending on which direction its electric field is oscillating in.

种振荡很重要，因为您可以限制通过滤光片的光，具体取决于其电场的振荡方向。

And notice, if we rotate the whole setup, say by twisting the initial polarizing filter, then that changes the components of each pure frequency that happen to be vertical resulting in a different balance of all those colours.

请注意， 如果我们旋转整个装置，比如转动初始的偏振滤光片，那么就会改变每个纯频率成分中恰好垂直的部分， 从而导致所有些颜色的平衡发生变化。

Well, there will be some scattering, I suppose, but then if we just look the tube, we're not applying any kind of filter to just looking directly at the tube.

- 嗯， 我想会有一些散射，但如果我们只是看试管，那我们并没有使用任何滤光片直接观察试管。

And if you look at this whole setup from the top, as you rotate one of those filters, you'll see different colors.

而且， 如果你从顶部观察整个装置，当你旋转其中一个滤光片时，你会看到不同的颜色。

And it doesn't have to be the first filter, if you rotate that second filter, you also rotate through these various different colours.

而且它不必是第一个滤光片，如果你旋转第二个滤光片， 你也会经过些不同的颜色。

The effect that has is that the amount of light of a given frequency passing through is equal to the component of its polarization direction that lines up with the filter.

样产生的效果是，特定频率的光透过量等于其偏振方向与滤光片对齐的分量。

Which is why rotating the initial filter changes the colour you see coming out the other end.

就是为什么旋转初始滤光片会改变你从另一端看到的颜色。

And the other thing I want to draw your attention to is the colour that's coming out of the tube after it passes through that second filter.

另外我要提请你注意的是，光线经过第二个滤光片后从管子中来的颜色。
