In 2022, the term “metaverse” was named Word of the Year by the Oxford Dictionary.
In the same year, the industry responded actively. Nearly 20 cities in China issued official documents to release strategic plans for the development of the metaverse, supporting its growth in terms of technology, applications and scenarios, and providing policy support for the metaverse.
During this year, many tech companies also devoted themselves to the development of the metaverse, striving to overtake in fields including industrial applications, underlying technologies and virtual humans, and driving the practical implementation of the metaverse concept at the industrial level.

The industries and technologies encompassed by the metaverse are diverse and multifaceted, among which VR/AR devices are the key to unlocking the door to the metaverse. For the consumer market to scale up, imaging quality and wearing experience are critical factors. As a vital component of VR/AR devices, optical modules determine both imaging quality and sensory comfort.
As an expert in precision fluid technology, Seamoon Technology has long been deeply engaged in the display sector, boasting leading domestic technological advantages in high-end display applications that have been widely adopted across the industry. Recognizing the vast prospects of the VR/AR industry, Seamoon took an early lead in entering the VR/AR field and launched joint R&D with top global customers. Starting with the core challenge of optical bonding technology, after years of repeated exploration and iteration, the company successfully developed an automated solution for VR optical bonding in 2018. In 2019, it commercialized high-precision stacking for AR optical waveguides and a fully automatic production line for VR optical bonding. In 2020, Seamoon introduced thin-film encapsulation for VR/AR micro-displays, which was widely promoted and implemented across the industry in 2021. To date, the company has been granted 24 patents in the wearable device industry.

The module production process of the currently popular optical pancake solution includes multiple procedures such as optical design, lens processing, lens film pasting, and assembly. Its core difficulty lies in the bonding of the screen and the folded optical path composite optical film, and the film pasting process is a key factor determining its imaging quality. The superposition and pasting of multiple layers of high-precision optical films need to take into account issues such as precision, stray light, optical axis alignment and focusing, and contamination. Each layer of film has precise and ultimate bonding requirements to ensure that the optical path still delivers an immersive and realistic sensory experience after high magnification and refraction.
At present, the fully automatic film pasting technology independently developed by Seamoon Technology has taken the lead in passing the batch actual machine inspection of many leading enterprises, with its technology and market share far ahead. Currently, Seamoon Technology can realize the superposition and bonding of optical films of different types and hardness in the AR/VR field, as well as the precise bonding of optical lenses. Optical modules have a delicate structure and high cost. After long-term technical optimization and repeated iteration and selection for defects such as bubbles, dot scratches, film cracks, wrinkles, and foreign objects in the film pasting process, Seamoon Technology can increase the yield rate to 97.5%.
The fully automatic vacuum bonding integrated machine independently developed by Seamoon Technology is equipped with an algorithm-based intelligent control system and a massive process application database. It can achieve excellent multi-level variable curvature bonding, featuring exquisite craftsmanship, intelligence, high efficiency and precise bonding, and can be widely applied to the film coating of optical planes or special-shaped curved surfaces.

Micro-display Screen Solutions
Meanwhile, with the continuous development of metaverse technology and industrial ecology, the demand for VR products keeps growing. As a core component of VR products, micro-display products are also poised for rapid growth. Currently, mass-producible Micro OLED has become the preferred display technology for VR headset manufacturers in designing high-end VR devices.
Featuring a monocrystalline silicon chip substrate, Micro OLED has a pixel size one-tenth that of traditional display devices, with the advantages of small size, light weight, low power consumption and high PPI.
Building on years of technological accumulation in the high-end display field, Ximeng Technology can efficiently realize processes such as large-panel bonding and side dispensing, while minimizing bubbles and greatly improving bonding flatness and alignment accuracy.
The independently developed large-panel bonding equipment from Ximeng Technology is widely used in the packaging and bonding of Micro OLED. It can fully automate the integrated processes of dispensing, inkjet and bonding for silicon-based OLED and glass. Equipped with an algorithm-based intelligent control system and a massive process application database, it delivers outstanding high-precision, high-flexibility and intelligent bonding performance.

Precision Fluid Control
In recent years, relying on its advantages such as digitalization, patterning, additive manufacturing, low material waste and large-area printing, inkjet printing technology has shown great potential in the field of microfabrication, enabling ultra-high-resolution printing with minimum line width in the submicron region.
Since its establishment, Ximeng Technology has been committed to high-precision fluid control processes. Its independently developed inkjet printing equipment is efficient, low-consumption, flexible and intelligent, equipped with an independently developed control system and a core patented detection system to accurately monitor the inkjet status of each nozzle. It provides the industry with leading solutions for character and solder mask circuit printing.
In addition, its ink observation instrument can detect ink droplet speed, volume, angle and satellite droplets, and can scan driving conditions, which can greatly improve process accuracy and extend to fields such as lens optical processing.
Looking ahead to 2023, with the booming development of VR/AR, major manufacturers are accelerating their layout and continuous investment, which is expected to spawn a huge market in the next few years. At the same time, Ximeng's metaverse technology is also continuously upgraded, entering a positive cycle driven by both hardware and content.
Against the background that VR/AR has become the next blue ocean for consumer electronics under the metaverse, bonding and inkjet printing are indispensable processes in VR/AR. Ximeng Technology will continue to strive for progress, focusing on consolidating the optical module bonding and precision fluid control routes, helping to reduce the overall cost trend of the industry, and thus promoting the intelligent wearable field to become a continuous growth point for consumer electronics in the future.
