Apple Enters the Foldable Screen Market: A Major Test of “Technological Maturity” and “Supply Chain Reconfiguration”
Hello everyone, I’m your financial journalist. Today, we’re not talking about whether a new smartphone is user-friendly or not, but about the profound changes that the entire mobile phone industry chain is undergoing behind Apple’s release of its first foldable phone, the iPhone Duo, in September 2026.
In simple terms, Apple’s entry is like a “superbuyer” suddenly stepping into a market that has been around for seven years. What it brings is not just increased sales but also a reshuffling of the market rules, technical standards, and profit distribution. TrendForce (a market research firm) has aptly called 2026 the “year of structural reorganization” for the foldable screen market.
To make it easier for you to understand, I’ve broken down this news into five key aspects and explained the ins and outs in plain language.

1. Why Now? Apple Thinks the “Technological Threshold” Has Been Reached
Many people wonder why Apple is entering the foldable screen market now, given that they have been around for seven years. It’s like cooking a complex dish: although the ingredients (technologies) were available before, the cooking skills (quality and precision) were lacking, resulting in products that were either prone to damage or had poor quality, making them unsuitable for mass production.
Apple believes that three key technologies have now met the necessary thresholds, moving from being “usable” to being “ready for mass production”:
- UTG (Ultra-Thin Glass): Foldable screens used to break easily, but now the glass is as thin as paper (30 microns) and yet tough and durable.
- Hinge Precision: The folding mechanism is as precise as a clock, with smooth opening and closing.
- Foldable OLED Yield: Only when the production yield of screens increases can costs decrease, allowing Apple to start mass-producing foldable phones.
In layman’s terms: Apple wasn’t unwilling to enter the market, but it wasn’t economically viable before. Now that the technology is mature, Apple’s entry will disrupt the industry, forcing other brands like Samsung, Huawei, and Xiaomi to either upgrade their technology or adjust their strategies, thus raising the technical barriers for the entire industry.

2. What’s So Special About the iPhone Duo? A Breakdown of Three Major Challenges
The technical highlights of the iPhone Duo focus on three of the most difficult aspects:
1. The Hinge: A Precision Joint Like a Clock
This is the heart of the foldable screen. Apple invested heavily in:
- Many Parts: The hinge consists of over 100 components, making it much more complex than previous phones.
- New Materials: The core shaft uses zirconium-based amorphous alloy (commonly known as liquid metal), which is hard and lightweight; the casing is made of recycled titanium 3D printing, both environmentally friendly and durable.
- Smooth Operation: A “variable torque mechanism” ensures a consistent resistance when folding.
- Challenges: Although the product looked perfect at launch, supply chain reports showed that the initial yield was only 30%-65%, rising to 60%-70% shortly before the release, indicating the high technical difficulty.
2. The Screen: Ten Layers of “Sandwich” to Eliminate Wrinkles
Previous foldable screens had visible wrinkles. The iPhone Duo’s inner screen uses ten layers of ultra-thin materials stacked together:
- It’s not just one piece of glass; the combination of UTG glass, optical adhesive, OLED module, and support structure smooths out the wrinkles.
- This is like making a thousand-layer cake—each layer must be thin and even to achieve a flat surface.
3. Battery and Cooling: Innovations to Fit the Large Chip
- Dual Batteries: Due to the thin body (11.3mm), a large battery couldn’t fit, so Apple used two batteries on either side of the phone for the first time.
- High-Silicon Anode Batteries: Supplier Zhuhai Guanyu provided new batteries with 32% silicon content, offering higher energy density and smaller size.
- Advanced Cooling: To handle the powerful A20 Pro chip (35% more powerful than the iPhone 17 Pro), Apple used VC thermal management plates, essentially a “miniature air conditioner” for the phone.
In layman’s terms: Apple redesigned the phone’s internal structure to achieve a balance between thinness and performance.

3. Who’s Making the Money? The Upgraded Role of Chinese Supply Chains
Apple’s entry is good news for Chinese supply chain companies, but there are both positives and negatives:
1. Chinese Companies’ Role: From “Supporting Players” to “Key Players”
Over the past seven years, Android phones have driven the development of foldable screens, giving Chinese companies experience in hinge components, UTG processing, and batteries. Apple’s large-scale orders have transformed these small, project-based orders into significant business opportunities.
- Hinge Components:
- Assembly: Foxconn and Shin-Ei (Taiwan) lead the way.
- Chinese Suppliers: Lingyi Manufacturing (stamping, carbon fiber boards), Yian Technology (liquid metal shafts), Jingyan Technology (precision parts).
- Screens:
- Panels: Samsung Display supplies exclusively (only signing three-year contracts when yield exceeds 80%).
- UTG Glass: Lens Technology and BOE split the market 50-50; Lens Technology also provides glass support plates and PET films.
- Batteries and Cooling:
- Cells: Zhuhai Guanyu (high-silicon anode batteries).
- Modules: Desay Battery, Xinwangda.
- Cooling: Lingyi Manufacturing (VC thermal management plates, battery casings).
2. The Catch: The Most Valuable Parts Still Controlled by Overseas Manufacturers
Although Chinese companies are deeply involved, the most valuable parts—hinge assemblies and OLED panels—are still dominated by foreign firms (Foxconn/Shin-Ei, Samsung).
- Chinese companies mainly provide secondary components, with relatively lower profits.
- The real opportunities lie in high-tech materials like UTG and liquid metal, where Chinese companies can gain more influence.
In layman’s terms: While Chinese companies supply essential components, the core technologies (panels and hinges) are still in the hands of foreign companies. They are transitioning from providing basic parts to developing key technologies.

4. Where’s the Money Going? Increased Value, but Financial Results Haven’t Yet Materialized
Foldable phones are more expensive than traditional phones. Why?
- Cost Breakdown: The core components of a foldable iPhone cost:
- Foldable OLED panel: $380-420
- Hinge system: $90-150
- UTG glass: $70-175
- Titanium alloy frame: $60-80
- Total: $600-825, accounting for over 40% of the BOM cost!
This means that companies controlling these components control most of the profits.
- Financial Performance: Although the logic is promising, financial reports from the first half of 2026 show mixed results:
- Foldable-related companies (e.g., Zhuhai Guanyu, Lens Technology) saw revenue growth but declining profits or even losses.
- Reasons: Low yields at the start of mass production, high R&D costs, and high equipment depreciation.
- Expectations: Profits are expected to improve in the second half of the year as yields increase and economies of scale take effect.
- Traditional Apple supply chain companies (e.g., Luxshare Precision, Dongshan Precision) performed better.
- Luxshare Precision: 40.2% revenue growth due to diversified businesses in automotive and communications.
- Dongshan Precision: 290% net profit growth from optical modules and AI PCBs, as well as components for new energy vehicles.
In layman’s terms: Foldable screens have long-term potential, but short-term profits are still limited. Companies that have diversified into AI, automotive, and optical modules are doing well. Foldable-related companies are still in the investment phase and need to see substantial profits after mass production.

5. The Profit Chain: Equipment Manufacturers Benefit First, but Don’t Focus Only on Foldable Screens
In a gold rush, those who supply the tools often profit first. Foldable screen production is more complex, requiring more sophisticated equipment:
- Equipment Manufacturers’ Advantage: Apple and contract manufacturers need to buy equipment and build production lines before mass production, so their revenue is recognized earlier than that of component suppliers.
- For example, panel bonding, UTG thinning, and hinge assembly require high-precision equipment.
- This means equipment manufacturers will see revenue in the first half of 2026, while component suppliers may start shipping in the second half.
- Don’t Overlook Other Drivers: Although equipment manufacturers’ reports show strong growth, it’s driven by multiple factors, not just foldable screens:
- Tianzhun Technology: High revenue from AI manufacturing equipment and robotics, unrelated to foldable screens.
- Bozhong Precision: 72.4% revenue growth, with the new energy business accounting for 52.7% of sales; foldable screen equipment’s contribution will be clearer in the second half.
In layman’s terms: Equipment manufacturers benefit from the expansion of foldable screen production, but their main growth comes from other emerging fields like AI, new energy, and robotics. Focusing solely on foldable screens may overlook their real growth drivers.

Summary: What Does Apple’s Foldable Screen Market Mean?
- Technological Maturity: Foldable screens are moving from a novelty to a mainstream product, with Apple accelerating this transition.
- Supply Chain Reconfiguration: Chinese companies are gaining more importance in key areas, but core components are still controlled by foreign firms.
- Performance Lag: Foldable-related companies are facing challenges, with the second half of the year being a critical period for profit improvement.
- Diversification is Key: Traditional Apple supply chain giants are diversifying into AI, automotive, and optical modules to reduce reliance on single phone businesses.
Advice for Investors: When considering investments, focus on companies that control core technologies and have diversified businesses. Be cautious of those that rely on foldable screen trends without solid financial results. The financial reports for the second half of 2026 will be crucial for assessing their true performance.
