㈠ 3D显示技术科普

先说3D，其实3D就是指的三维，简单说：x、y、z，后面的裸眼3D，全景，VR，AR，MR都离不开这个3D基础。那么通过3D建模手段形成的三维模型然后经过渲染后（3D内容资源）或加交互（交互3D内容）后，就形成3D内容。

从1950年出现分色眼镜即彩色滤光方式实现3D技术再到1980年出现快门式眼镜与偏光式眼镜辅助3D显示，再到2010年左右出现的虚拟与现实以AR/VR眼镜为代表+自由立体技术即裸眼3D显示技术为代表的发展历程，未来以真正的三维（裸眼）为主导的显示技术将会成为未来的方向与趋势。

效果图：

自由立体三维就是我们说的裸眼3D可分为光屏障式（Barrier）、柱状透镜(Lenticular Lens)技术和指向光源（Directional Backlight）

真正的三维显示迹慎碰最适合自然环境下的3D显示，观看的距离与位置不受限制，跟真实的环境一样，分辨率与真实无异。这是未来10-20年的方向，也是人类最想完成的。

国内外研究方向：多方向背光集成、基于光泳光学捕捉的3D立体显示、基于多模式声学捕获的3D显示、基于神经网络的计算全息图实时生成方法（MIT）、多维空间光学调控3D光场显示（北邮）、分层角谱全息显示（清华）
真正的三维显示姿谈目前问题：3D视角小、3D融合假、3D生成慢、3D信息少等问题。

带特殊功能就可以加红外感应点，产生更好的效果。如下图：

早期的CardBoard，到2016年HTC推出的基于PC端的Light house技术的HTC Vive，然后从outside-in定位技术再到outside-out的Pico。

一般称为MR眼镜、XR眼镜,也有叫增强现实眼镜，根据技术不同：HoloLens、Magic Leap、耐德佳显示技术公司的AR眼镜、亮风台AR眼镜、Rokid公司的AR眼镜、孝局爱普生智能AR眼镜。AR眼镜现阶段有两个制约发展的点：1、视场角大小（FOV）2、体积
国内缺点：显示出来的画面质量不高，视角有局限，
目前市场上有的：衍射光波导与阵列光波导，未来的发展是衍射光波导。

这个是比较适合普通人员眼镜使用的，如果是工业安防领域，可能需要更大的视角

小米发布的AR眼镜明确表示了：MicroLED光波导显像技术。通俗点说：将画面通过光线转折，再反射到人眼中。

元宇宙是整合多种新技术而产生的新型虚实相容的互联网应用和社会形态，基于显示技术提供沉浸式、互动式的体验，生成具有对应现实世界关系的镜像。

㈡ “元宇宙”概念个股业绩到底如何

答：您好，成熟的元宇宙产品需要5-10年的技术以及用户数量上的沉淀。因此，在基础设施尚未普及之前，元宇宙目前很难从业绩上直观体现。从“A股元宇宙游戏第一股”中青宝公司股价随着市场情绪推动，十天内股价翻倍。业绩方面，公司前三季度营业收入为2.57亿元，同比增长28.5%；归属上市公司股东净利润1356.5万元，同比增长730.2%。
看似不错的成绩单其实暗藏玄机。中青宝第三季度净利润为201.8万元，同比增长127.9%，分季度看，公司每个季度净利都呈下降趋势，高增速其实是2020年的低基数造成。

一、汤姆猫业绩：
与中青宝情况相似的还有汤姆猫。自元宇宙概念炒作以来，公司股价已累计上涨37.85%。公司三季报业绩同样表现不错，前三季度营业收入为14.02亿元，同比增长13.23%；归属于上市公司股东扣非净利润为5.88亿元，同比增长8.03%。其中，公司第三季度营业收入4.85亿元，同比增长44.14%；扣非净利润1.8亿元，同比增长70.58%。对于业绩增长原因，汤姆猫认为是源于核心游戏产品矩阵保持了稳定的长线运营。但公司在元宇宙业务方面也仍处于探索阶段未实现盈利，所有有关元宇宙概念的项目还都停留在专项工作室阶段。

二、歌尔股份
歌尔股份营业收入527.89亿元，同比增加52%；净利润33.33亿元，同比增加65.28%；经营性现金流净流入57.59亿元，同比增加112.68%。歌尔股份在第三季度营收以及净利增速略有下降，分别为17.46%、29.61%，不过依然符合市场预期。
2021年前三季度，歌尔股份精密零组件业务收入102.9亿元，同比增长23.86%；智能声学整机业务收入192.0亿元，同比增长25.72%。此外，公司智能硬件业务收入同比增长119.07%至222.3亿元。从细分业务增速上看，歌尔股份正逐渐从“果链”到“元宇宙”方向进行过度，VR/AR硬件块收占比逐年显著提升。

㈠ Popular science on 3D display technology

Let’s talk about 3D first. In fact, 3D refers to three dimensions. Simply put: x, y, z, followed by naked-eye 3D, panorama, VR, AR, MR All are inseparable from this 3D foundation. Then the three-dimensional model formed through 3D modeling means is then rendered (3D content resources) or interacted (interactive 3D content) to form 3D content.

From the emergence of dichroic glasses, that is, color filtering, to realize 3D technology in 1950, to the emergence of shutter glasses and polarized glasses to assist 3D display in 1980, to the emergence of virtual and reality around 2010. The development process is represented by AR/VR glasses + free stereoscopic technology, that is, naked-eye 3D display technology. In the future, display technology dominated by true three-dimensional (naked-eye) will become the future direction and trend.

Rendering:

Free three-dimensional 3D is what we call naked-eye 3D, which can be divided into light barrier (Barrier), lenticular lens (Lenticular Lens) technology and directional light source (Directional) Backlight)

The true three-dimensional display trace is most suitable for 3D display in natural environment. The viewing distance and position are not restricted. It is the same as the real environment, and the resolution is the same as the real one. This is the direction for the next 10-20 years, and it is also what mankind wants to accomplish most.

Domestic and foreign research directions: multi-directional backlight integration, 3D stereoscopic display based on photophoretic optical capture, 3D display based on multi-mode acoustic capture, neural network-based computational hologram real-time generation method (MIT), multi-dimensional space optics Controlling 3D light field display (Beijing University of Technology), hierarchical angular spectrum holographic display (Tsinghua University)
The current problems of true 3D display are discussed: small 3D viewing angle, false 3D fusion, slow 3D generation, little 3D information, etc.

With special functions, you can add infrared sensing points to produce better results. As shown below:

From the early CardBoard, to the HTC Vive launched by HTC in 2016 based on the PC-side Light house technology, and then from the outside-in positioning technology to the outside-out Pico.

Generally called MR glasses, XR glasses, also called augmented reality glasses, depending on the technology: HoloLens, Magic Leap, Nedjia Display Technology Company’s AR glasses, Liangfengtai AR glasses, Rokid Company AR glasses, Xiaoju Epson smart AR glasses. There are two points that restrict the development of AR glasses at this stage: 1. Field of view (FOV) 2. Volume
Domestic shortcomings: the quality of the displayed picture is not high and the viewing angle is limited.
Currently on the market There are: diffractive optical waveguides and array optical waveguides, and the future development is diffractive optical waveguides.

This is more suitable for ordinary people to use glasses. If it is in the field of industrial security, a larger viewing angle may be needed

The AR glasses released by Xiaomi clearly stated: MicroLED optical waveguide imaging technology. In layman's terms: the image is transformed by light and then reflected into the human eye.

The Metaverse is a new type of Internet application and social form that is compatible with reality and reality by integrating a variety of new technologies. It provides an immersive and interactive experience based on display technology and generates mirror images that correspond to real-world relationships. .

㈡ What is the performance of the "Metaverse" concept stocks?

Answer: Hello, mature Metaverse products require 5-10 years of technology and accumulation of user numbers. Therefore, before the infrastructure is popularized, it is currently difficult to intuitively reflect the performance of the Metaverse. From the "first A-share Yuanverse game stock", Qingbao's stock price doubled in ten days as market sentiment drove it. In terms of performance, the company's operating income in the first three quarters was 257 million yuan, a year-on-year increase of 28.5%; net profit attributable to shareholders of listed companies was 13.565 million yuan, a year-on-year increase of 730.2%.
The seemingly good transcript actually hides a secret. Zhongqingbao's net profit in the third quarter was 2.018 million yuan, a year-on-year increase of 127.9%. Looking at the quarterly analysis, the company's net profit showed a downward trend in each quarter. The high growth rate was actually caused by the low base in 2020.

1. Tom Cat’s performance:
Similar to Zhongqingbao’s situation is Tom Cat. Since the Yuanverse concept was hyped, the company's stock price has risen by a cumulative 37.85%. The company's third-quarter results also performed well. Operating income in the first three quarters was 1.402 billion yuan, a year-on-year increase of 13.23%; non-net profits attributable to shareholders of listed companies after deducting non-net profits were 588 million yuan, a year-on-year increase of 8.03%. Among them, the company's operating income in the third quarter was 485 million yuan, a year-on-year increase of 44.14%; deducting non-net profit was 180 million yuan, a year-on-year increase of 70.58%. As for the reason for performance growth, Tom Cat believes that it is due to the core game product matrix maintaining stable long-term operations. However, the company is still in the exploratory stage of its Metaverse business and has not yet achieved profitability, and all projects related to the Metaverse concept are still in the special studio stage.

2. Goertek
Goertek’s operating income was 52.789 billion yuan, a year-on-year increase of 52%; net profit was 3.333 billion yuan, a year-on-year increase of 65.28%; operating cash flow net inflow was 5.759 billion yuan, a year-on-year increase An increase of 112.68%. Goertek's revenue and net profit growth rates dropped slightly in the third quarter, to 17.46% and 29.61% respectively, but they were still in line with market expectations.
In the first three quarters of 2021, Goertek Precision IndustryThe component business revenue was 10.29 billion yuan, a year-on-year increase of 23.86%; the intelligent acoustic complete machine business revenue was 19.20 billion yuan, a year-on-year increase of 25.72%. In addition, the company’s smart hardware business revenue increased by 119.07% year-on-year to 22.23 billion yuan. Judging from the growth rate of segmented businesses, Goertek is gradually transitioning from the "fruit chain" to the "metaverse" direction, and the proportion of VR/AR hardware block revenue has increased significantly year by year.
