The latest MicroLED solution from Guanglian benefits the three major "water sellers" and "gold miners"!

Drive: The latest alternative to Light Interconnection has been released. Compared to traditional laser solutions, MicroLED reduces power consumption by up to 68%, with transmission distances reaching 50 meters. This falls between short-distance copper cables and long-distance optical modules, potentially breaking the dilemma of choosing between “light” and “copper.” Currently, leading overseas companies have launched product roadmaps, with Microsoft developing an 800G prototype, where MicroLED chips, lenses, and CMOS sensors are core incremental components.

Significant Increment: Traditional screens use only dozens of LEDs, while MicroLED screens require millions. The light source for MicroLED CPO (co-packaged optics) will shift from lasers to MicroLED chips, representing the most critical incremental step.

Yesterday, there were many one-character or seconds boards, especially 20% seconds large boards, and 30% super-large boards! Such situations are very rare!

This morning, the surge was mainly driven by various MicroLED manufacturers, with all manufacturers’ “water sellers” and “gold rushers”—such as Silicon Power, Delong Laser, Saiwu Technology—being the biggest beneficiaries of the latest MicroLED solutions in Light Interconnection!

1. Silicon Power

In the cutting-edge architecture of MicroLED, especially MicroLED CPO (co-packaged optical) interconnection, Silicon Power acts as the “gatekeeper” in testing stages. Its core incremental logic has evolved from simple “screen display testing” to “deterministic screening of core AI computing components.”

MicroLED chips have shifted from “spot checks” to “100% KGD” (Known Good Die), with both volume and price increasing. In the CPO architecture, MicroLED is no longer just a pixel but a high-speed communication light source. An 800G/1.6T optical interconnection module requires hundreds or even thousands of chips. Since the assembled modules are extremely expensive and non-repairable, manufacturers must perform KGD screening on each micron-scale chip before transfer.

The number of chips has crossed from “display-level” to “computing cluster-level,” causing a surge in testing throughput demand at Silicon Power’s probe stations. Additionally, communication-grade chips require much higher testing precision for leakage current and response speed than display-grade chips, boosting high-value high-end probe station sales.

Overall MicroLED process: Data feedback center for yield in massive transfer.

Massive transfer is currently recognized as a process bottleneck. To optimize transfer parameters of equipment like Delong Laser, Silicon Power provides extremely detailed “failure analysis data.”

Silicon Power not only sells hardware but also its testing data has become central to process optimization in the industry chain. As MicroLED chip sizes shrink from 50μm to 10μm or smaller, only domestically produced equipment with micron-level alignment accuracy (±1μm) like Silicon Power can handle this task, creating a strong technological barrier and customer stickiness.

Microsoft’s 800G prototype uses a MicroLED solution. Silicon Power is one of the few global manufacturers capable of providing massive MicroLED testing equipment. This means that if Microsoft’s solution enters large-scale mass production, its foundries (such as TSMC, San’an) must purchase Silicon Power’s probe stations to ensure chip yield.

Silicon Power’s client list nearly covers major domestic MicroLED leaders: San’an Optoelectronics, Huacan Photoelectric, Zhaochi Co., Ltd., Qianzhao Optoelectronics, Silan Micro, Jucan Optoelectronics, etc.

Microsoft’s future may adopt Silicon Power’s MicroLED chips as the main device supplier, acting as an “invisible quality inspector” behind Microsoft’s terminal devices.

With explosive growth, traditional screens use only dozens of LEDs, while MicroLED screens require millions. Each must be tested, leading to a hundredfold increase in testing device demand.

In simple terms: The more widespread MicroLED and CMOS become, the more booming Silicon Power’s business will be. The relationship between Silicon Power and these major manufacturers is essentially that of “water sellers” and “gold miners.”

2. Delong Laser

Delong Laser acts as the “photon surgical knife” for these high-precision components, the “savior” of MicroLED chip yield. This is currently Delong Laser’s strongest growth logic. In summary: for Delong Laser, entering the CPO field for MicroLED means its equipment shifts from “optional” to “mandatory.”

Laser massive transfer + laser peeling + laser repair form its “iron triangle” of technological moat in the AI computing light interconnection track. Delong Laser is both a MicroLED surgical knife and transporter, offering a full range of solutions including laser processing, laser peeling, massive transfer, laser repair, and large-scale welding.

3. Saiwu Technology

Key material supplier, providing specialized adhesives and UV anti-adhesion films for MicroLED transfer processes. These are used for temporary fixation and precise release during chip transfer, representing core chemical materials in massive transfer technology.

Related stocks for MicroLED solutions: Huacan Photoelectric (20% one-character), Silicon Power, Delong Laser, Saiwu Technology, Medike (20% board), San’an Optoelectronics (second board), Wentai Photonics (over 30% board), Longteng Photonics (20% seconds), Jucan Photoelectric (20% seconds), Fuman Photonics (20% seconds), Leyard Optoelectronics (20% seconds), Lianjian Optoelectronics (20% seconds), Absen (20% seconds), Refond Photoelectric (20% seconds), Vog Photonics, Zhaochi Co., Ltd., Guoxing Photonics, etc.

So many one-character or seconds boards, especially 20% seconds and 30% super-large boards! Such situations are very rare! Basically, all MicroLED manufacturers, with Silicon Power, Saiwu, and Delong as the top “water sellers” and “gold miners,” are the biggest beneficiaries of the latest MicroLED solutions in Light Interconnection!

The three top “water sellers” and “gold miners” have strong demand for revaluation and are worth期待！
