最近，我们的一些朋友问ClearBlack是什么以及为什么我们总是说它如此出色。不幸的是，除了我们的 Lumias 上可用的ClearBlack(ClearBlack)屏幕看起来(Lumias look)非常好之外，我们无法告诉他们其他任何事情。“黑色就是黑色”，即使您在户外，在明亮的光线下，您也可以看到它们上显示的内容。正如你可以想象的那样，我们对我们没有那么有用的解释感到沮丧。于是我们开始在互联网(Internet)上进行挖掘，以了解更多关于诺基亚(Nokia)ClearBlack 技术(ClearBlack technology)以及它为何如此出色的信息。这是我们发现的：
为什么需要 ClearBlack 技术(Was ClearBlack Technology Needed)？
在深入了解有关ClearBlack 技术(ClearBlack technology)的更多技术细节之前，我们认为了解它在好处方面提供了什么以及为什么它很棒是非常重要的。
在过去十年左右的时间里，智能手机和平板电脑等其他移动设备对我们来说变得越来越重要。我们现在几乎在任何地方都在使用这些设备，它们在任何条件下都可以使用非常重要。撇开智能手机或平板电脑中的所有硬件不谈，用户体验中最重要的组成部分之一就是屏幕。制造商面临的最大挑战之一是使他们设备的屏幕足够亮，即使在户外使用时也能清晰阅读。起初，制造商正在开发亮度级别越来越高的屏幕，这导致了一个十字路口。每当你增加屏幕的亮度时，你必须向它注入更多的能量。这意味着您需要使用更大容量的电池。但这只能达到一定程度，当您根本无法放置(bulky battery)优雅的智能手机上的大容量电池。到了这一点，您必须寻找其他更好的方法来构建屏幕。这就是诺基亚(Nokia)开始开发其ClearBlack 技术(ClearBlack technology)的地方。
ClearBlack 设法提高了屏幕的户外可用性，在电源需求方面没有做出任何妥协。
ClearBlack 技术(ClearBlack Technology Work)如何工作？
ClearBlack 屏幕(ClearBlack screen)使用旨在消除反射的显示器。当然，大多数制造商在ClearBlack(ClearBlack)开发之前就已经使用了抗反射涂层。但诺基亚(Nokia)希望找到一种方法来进一步提高其屏幕的性能。所以他们开始研究其他消除反射的方法，最终研究了偏振光。
正如Lumia Conversations博客中所述，ClearBlack 技术(ClearBlack technology)的工作方式与偏光太阳镜的工作方式类似。偏光玻璃可消除反射，让您在明亮的环境中更容易看清事物。这就是为什么几乎每个渔民或滑雪者都使用这种太阳镜的原因。
然而，这种比较并不是最好的，因为ClearBlack使用了更复杂的偏光层。进出ClearBlack 屏幕(ClearBlack screen)的光线在到达您的眼睛之前会经过多次处理。我们不会涉及非常技术性的细节，因为这不是我们文章的重点。但是，如果您想了解ClearBlack实际工作原理的详细信息，请查看下图或阅读诺基亚(Nokia)发布的一些解释，这里：诺基亚的 ClearBlack 显示器如何提供不败的结果(How Nokia's ClearBlack display delivers unbeaten results)（本文是下图的来源） .
ClearBlack 屏幕(ClearBlack Screens Look)是什么样的？
在不进行视觉比较的情况下谈论这样的主题会有所帮助吗？我们认为它不会，所以我们认为在没有 ClearBlack 的显示器旁边拍摄几张 ClearBlack 屏幕的照片是个(ClearBlack)好主意(ClearBlack)。
在下图中，您可以看到两个ClearBlack屏幕（来自诺基亚 Lumia 930(Nokia Lumia 930)和诺基亚 Lumia 820(Nokia Lumia 820)）与其他一些显示器（小米米 4(Xiaomi Mi 4)、小米红米 2(Xiaomi Redmi 2)和三星 Galaxy S(Samsung Galaxy S)）相比的外观。
请注意，我们在上面的每部智能手机上都打开了相同的网页，并且它们都处于可用的最高亮度设置。如您所见，前两款智能手机——Lumia 930和Lumia 820——拥有更亮的显示屏，这要归功于它们使用的ClearBlack 技术。(ClearBlack technology)
为了演示我们告诉您的关于“黑色就是黑色”的内容，请看下一张照片。我们创建了一张全黑的图片，然后在这两款智能手机上打开它：带有ClearBlack的(ClearBlack)Lumia 930和没有ClearBlack的小米 Redmi 2(Xiaomi Redmi 2)。你能看出区别吗？ClearBlack 屏幕(ClearBlack screen)比其他屏幕反射的不需要的光要少得多。ClearBlack比(ClearBlack)魔多(Mordor)最黑暗的夜晚中最黑暗的咒语还要黑！🙂
结论
ClearBlack是一项伟大的技术，可以优雅地增强各种显示器的可用性。以与我们开始时相同的说明结束：“黑人就是黑人” ，无论您是在室内还是室外， ClearBlack显示器看起来都非常好。(ClearBlack)
Simple Questions: What Is The Clearblack Technology And Why Is It Great?
Recently, some of our friends asked what ClearBlack іs and why we always saу it's ѕo great. Unfortunately, we couldn't tell them anything else except that the ClearBlack screens available on our Lumias look really good. The "black is black" and you can see what's displayed оn them even when you're outdoors, in bright lіght. As you can imagine, we felt frustrated abоut our not so helрful explanation. So we started digging on the Іnternet, in order to find more about Nokia's ClearBlack technology and why it is awesome. Here's what we've found:
Why Was ClearBlack Technology Needed?
Before getting into a bit more technical details about the ClearBlack technology, we think that it is very important to see what it offers in terms of benefits and why it's great.
In the last decade or so, smartphones and other mobile devices like tablets have become more and more important to us. We are now using these devices almost everywhere and it's very important that they be usable in any conditions. Putting aside all the hardware you find in a smartphone or a tablet, one of the most important components from a user's experience is the screen. One of the manufacturers' greatest challenges is to make their devices' screens bright enough to be readable even when used outdoors. At first, manufacturers were developing screens with higher and higher brightness levels and that lead to a crossroad. Whenever you increase the brightness of the screen, you must pump more energy into it. That means you need to use larger capacity batteries. But that can only go up to a point, when you simply cannot put a bulky battery on an elegant smartphone. When you get to this point, you must search for other, better ways of building a screen. This is the point where Nokia started developing their ClearBlack technology.
ClearBlack manages to improve the outdoor usability of the screen, without making any compromises when it comes to the power needs.
How Does The ClearBlack Technology Work?
A ClearBlack screen uses a display designed to eliminate reflections. Sure, most manufacturers already used anti-reflective coatings before ClearBlack was developed. But Nokia wanted to find a way to further increase the performance of its screens. So they started to work on other ways of eliminating reflections, and they ended up researching polarized light.
As mentioned on the Lumia Conversations blog, ClearBlack technology works in a similar way with how polarising sunglasses do. The polarised glass cuts out reflections, making it easier for you to see things in bright environments. That's why almost every fisherman or skier uses such sunglasses.
However, this comparison is not the best to make, as ClearBlack uses much more sophisticated polarising layers. The light that goes in and out of a ClearBlack screen is processed several times before it reaches your eyes. We won't go into very technical details, because that's not the point of our article. However, if you want to know the details of how ClearBlack actually works, take a look at the picture below or read some explanations posted by Nokia, here: How Nokia's ClearBlack display delivers unbeaten results (this article is the source for the image below).
What Do ClearBlack Screens Look Like?
Would it help to talk about such a subject without making a visual comparison? We don't think it would, so we thought it would be a good idea to take a few pictures of ClearBlack screens, alongside displays without ClearBlack.
In the picture below you can see how two ClearBlack screens (from a Nokia Lumia 930 and a Nokia Lumia 820) look when compared to some other displays (Xiaomi Mi 4, Xiaomi Redmi 2 and Samsung Galaxy S).
Note that we opened the same webpage on every smartphone above and that all of them were on the highest brightness setting available. As you can see, the first two smartphones - Lumia 930 and Lumia 820 - have much brighter displays, thanks to the ClearBlack technology they use.
And to demonstrate what we were telling you about "black is black", just take a look at the next photo. We created a completely black picture and then opened it on both these smartphones: the Lumia 930 with ClearBlack and the Xiaomi Redmi 2, without ClearBlack. Can you see the differences? The ClearBlack screen simply reflects a lot less unwanted light than the other. ClearBlack is blacker than the darkest spell in the darkest night of Mordor! 🙂
Conclusion
ClearBlack is a great technology that elegantly enhances the usability of all kinds of displays. To end on the same note as we began: "blacks are blacks" and ClearBlack displays really look good, no matter if you're indoors or outdoors.
