The Xiaomi Mi Note 2 is equipped with a dual-curved 5.7-inch OLED display of FullHD resolution. That should amount to a 386ppi pixel density, but with the Pentile arrangement (or rather Diamond Pixel) that number isn't quite indicative of the screen sharpness.
小米Note 2配备了一块5.7英寸全高清分辨率的OLED双侧曲面屏幕。理论上分辨率可以达到386PPI，但是由于采用了Pentile 子像素排列方式（更精准地说是钻石排列）这个数字并不能和实际的屏幕清晰度匹配。
The Mi Note 2's uses an OLED panel made by LG. It's slightly different than Samsung AMOLED panels which have twice as many green pixels as there are blue and red ones. Here, there are twice as many blue subpixels than there are green and red ones.
小米Note 2使用了一块来自LG的OLED 屏幕。这块屏幕的子像素组成和三星的AMOLED 有一点点不同，三星的A屏红绿蓝子像素比例为1:2:1，而LG的这块屏幕红绿蓝子像素比例为1:1:2。
The subpixel arrangement is in fact the same type - Diamond Pentile - in both cases. Again, in both cases the concept of a single pixel consisting of RGB subpixels is replaced with subpixel rendering, where neighboring colored dots could be used depending on the content that needs to be output.
三星和LG 两种不同的OLED 面板中子像素的排列其实是一样的，都属于钻石排列。在这两种面板中，一个像素由红绿蓝三个子像素组成的排列方式被替换成了子像素共享，相邻的彩色像素点可以根据需要输出的内容而互相借用（这一段关于原理的解释可以直接度娘） 。
While the issue of sharpness is typically negated by throwing more pixels at it (read, QHD resolution) Xiaomi went with FullHD. We had to dig out a Galaxy Note 3 (itself 5.7" FullHD) for comparison and predictably the two displays have the same level of sharpness when rendering tiny texts for example, i.e. not the best. The thing is, the Galaxy Note 3 is a three-plus-year-old model, and the Mi Note 2 just came out.
当钻石排列的屏幕清晰度不足的问题通常可以通过增加子像素（增高分辨率）解决的时候（比如2K屏幕），小米Note 2却采用了一块1080P屏幕。我们不得不翻箱底找出一台三星Note 3（5.7英寸1080P）来进行对比，不出我们所料在显示一些小的文字内容的时候两者的清晰度是差不多的，也就是说表现并不好。最重要的是，三星Note 3是一款三年多年前的产品，而小米Note2最近才发布上市。
We gathered around the Mi Note 2 to share thoughts on the display and the general consensus was that you could see the fine weave of the diamond subpixel arrangement. When shot on camera the display exhibits some odd patterns too, but our resident DSLR with the right lens has way more resolving power than your human eye, so don't worry about seeing those in actual use.
我们把小米Note 2放在一起讨论这块屏幕的显示效果，我们一致认同的观点是你可以看见由于钻石排列产生的类似细密的编织物效果。当用相机翻拍的时候这块屏幕还显示出一些奇怪的图案，不过我们的单反相机配上合适的镜头解析力远超人眼，因此不用担心在使用过程中看到那些奇怪的图案。
In terms of brightness, the Mi Note 2 isn't great either. With a maximum value of 341nits the Mi Note 2 is some 100nits behind the OnePlus 3T, which is recently reviewed. The Galaxy S7 edge screen is brighter than the Mi Note 2 in manual mode already, but can also boost brightness much further in Auto - a feature the Xiaomi phablet lacks.
在亮度方面，小米Note2的表现也不是很好。最高亮度只有341尼特左右，比我们近期评测过的一加3T低了大约100尼特。S7e手动亮度就已经比小米Note2更高了，而且自动亮度下还可以触发鸡血模式显示更亮，这个功能也是小米Note2所欠缺的。
As for contrast, the Mi Note 2's display is OLED - the contrast ratio is for purposes practical that means infinite contrast. Now, our testing equipment detected minor illumination of the blacks, but that's mostly irrelevant.
至于对比度，小米Note2是OLED 屏幕——对意味着它的比度是无限大的（for purposes practical这个不会翻）。现在我们的测试仪器在显示黑色的界面检测到了微弱的光照，但这通常无关紧要。
Color reproduction is very accurate in Standard mode with an average DeltaE of 2.7, only this mode isn't the default one out of the box. The other two modes are less accurate but offer more punch - so pick the one you prefer.
在标准模式下屏幕色彩还原非常准确，平均色彩偏离值2.7，不过这个模式并不是来开箱使用后的默认模式。另外两种模式色彩还原没有那么准确但是更具冲击力，挑一个自己喜欢的模式就好了。
The other major issue with the display is that at any angle other than head-on, it has a strong bluish tint, which the testing rig can't catch because it examines it head-on.
另外一个主要的问题是这块屏幕只要不是在正面垂直观看，其他任何角度看都会偏浅蓝色，而我们的测试装置无法检测到，因为它是在屏幕正上方作业的。
Sunlight contrast ratio is actually pretty low for an OLED panel, too. In a time when good LCDs approach a value of 4 in our test, and the best OLEDs are in the ballpark of 4.5, the Mi Note 2's 3.228 is nothing special.
事实上OLED屏幕在阳光下的对比度是相当低的（这个地方和后面是有矛盾的……也许我翻译错误？或许原文有误？）在我们的测试中好的LCD屏幕阳光下对比度数值可以达到4，而最好的OLED屏幕大约是4.5，小米Note2的3.228没有什么特别之处。（这个数值越大越好）。
