原文标题：ElectronicsPixels in your eyeMaking VR displays more realistic电子设备你眼中的像素使VR显示图像更逼真的方法Micro LEDs produce sharper digital displays微型LED产生更清晰的数字显示屏[Paragraph 1]TO ENTER A virtual environment, users must don a set of VR goggles(see picture). Typically, these contain a pair of stereoscopic lenses and a light-emitting diode(LED) display screen. 用户想要进入虚拟环境，必须戴上一副“虚拟现实”眼镜（如图）。VR眼镜通常是由一对立体透镜和发光二极管（LED）显示屏组成。The lenses distort the image on the screen so that it appears to be in three dimensions. And various sensors in the goggles track the position of the user’s head, to co-ordinate that with what is being viewed. 透镜使屏幕上的图像失真，使其看起来是三维图像。眼镜里的各种传感器会跟踪用户头部活动位置，以使其与所观察的图像相协调。

[Paragraph 2]A group of researchers based at the Massachusetts Institute of Technology (MIT), along with colleagues at universities in France, South Korea and other parts of America, have come up with a way of arranging LED pixels to produce screens with a much higher resolutionthan is currently possible.

麻省理工学院的一组研究人员，加上法国、韩国和美国其他大学的同事，他们提出了一种排列LED像素点的方法，这种方法生产的屏幕分辨率比现有技术要高清许多。

As they report this week in Nature, their technique could be used to make VR images that appear far more lifelike than today’s.

正如他们本周发表在《自然》杂志上的论文所说，他们的技术可以用来制作更逼真的VR图像，且远远好于现有的效果。

“You could have a completely immersive experience and wouldn’t be able to distinguish virtual from reality,” claims Jiho Shin, one of the team’s members.研究团队之一的辛知勋说：“你可以有一种完全沉浸式的体验，以致于无法区分虚拟和现实。”[Paragraph 3]To generate displays with higher and higher resolution, LED pixels have been getting smaller and smaller.

显示器分辨率越来越高，LED像素点越小越好。

But this makes them ever harder to manufacture reliably. Some in the industry think a practical limit will soon be reached.

但这使得制造难度加大。一些业内人士认为，很快会小到实际极限。

Yet smaller pixels are especially valuable for improving screens that are viewed up close, as with a VR headset.

然而，对于近距离观看的屏幕（如VR眼镜）来说，更小的像素点对提高分辨率尤其重要。

Insufficient pixel density can result in unwanted optical illusions, such as perceived stripes in the image. 如果像素密度不足，就会导致不必要的视觉错觉，如图像中出现可见条纹。[Paragraph 4]At present, LEDs are made like silicon chips.

目前，LED的制造方式与制造硅片方式类似。

The red, green and blue versions required for a full range of colours are grown on different wafers, then cut out and placed side by side, with microscopic precision, to form pixels.

红色，绿色，蓝色可以产生各种各样的颜色，这三个子像素卡在不同的晶片上，然后切割，再并排放置，以显微精度形成像素。

Misalignment leads to rejection. And the smaller the LED, the greater the chance of misalignment.

错位会导致排斥反应。且LED越小，错位的概率越大。

Today’s LEDs can be pretty small (less than 100 microns across). But gogglemakers would prefer something far tinier than that.如今LED可能非常小（直径小于100微米）。但眼镜制造商热衷直径更小的LED。[Paragraph 5]Dr Shin and his colleagues think they can turn out such minusculeLEDs by going about things differently.

辛博士和他的同事认为，他们可以通过不同的方式来制造微型LED。

They grow their diodes directly on reusable wafers of silicon and other materials to produce a single-crystalline membrane.

他们直接在可反复利用的硅晶片和其他材料上卡二极管，以生产单晶膜。

These membranes can then be peeled away, stacked one on top of another like layers of a cake, and cut into patterns of tiny vertical pixels, each as little as four microns across. 然后，这些膜可以被剥离，像蛋糕一样一层一层地叠起来，然后被切成微小的垂直像素样式，每个像素只有4微米宽。

[Paragraph 6]As with conventional side-by-side LEDs, the team’s vertical ones yield a full spectrum.

与传统的并排LED一样，研究团队的垂直LED可以产生全光谱。

The result should be perfect for VR goggles. And screens for goggles could just be the start.

对于VR眼镜来说应该有完美的效果。虚拟眼镜屏幕可能只是一个开始。

Now that televisions come in curved and foldable forms, they, too, might be used to surround a viewer in a virtual environment.

现在，电视有曲屏和折叠屏，电视也可以用于在虚拟环境中包围观众的视线。

One day, perhaps, stacked micro LEDs might even take the immersive experience to the silver screen of cinema itself.或许有一天，堆叠的微型LED甚至可以将沉浸式体验带到电影院的银屏上。（恭喜读完，本篇英语词汇量476左右）原文出自：2023年2月4日《The Economist》Science & technology版块。

【补充资料】（来自于网络）虚拟现实眼镜，它是一种硬件设备，将人的对外界的视觉、听觉封闭，引导用户产生一种身在虚拟环境中的感觉。其显示原理是左右眼屏幕分别显示左右眼的图像，人眼获取这种带有差异的信息后在脑海中产生立体感。VR眼镜的主要配置就是两片透镜。VR透镜属于成像光学设计，透镜表面设计有平凸（非球面）、双凸和凹凸效果，透镜边缘薄，中心厚。凸透镜能修正晶状体的光源的角度，使其重新被人眼读取，达到增大视角、将画面放大、增强立体效果的作用，让人有身临其境的感觉。显示器里的景象，如果要随着人头部的运动而实时产生变化。则必须知道人头部的朝向，比如，当带着VR眼镜的人，向上看时，眼睛里的显示器，需要实时的显示虚拟的天空。在普通的OLED电视（或电脑屏幕）上，每个像素实际上是由三个OLED子像素组成的--一个红色、一个绿色、一个蓝色--它们并排排列。通过对这些微小的OLED进行不同组合的照明，像素能够产生广泛的颜色。美国麻省理工学院研究团队发明了一种堆叠二极管以创建垂直、多色像素的方法，该方法可用于制作更清晰、无缺陷的显示器。研究成果近日发表在《自然》杂志上。
