II. FMM Camp: The Steady Leading "Established Players"

1. Samsung Display (SDC): Clear First-Mover Advantage

  • Technology Route: FMM evaporation + Tandem OLED technology

  • Production Line Progress: The 8.6-gen line at Plant A6 has started construction; trial operation will begin in late 2025, with full mass production in Q2 2026

  • Customer Breakthrough: Secured exclusive orders from Apple to supply OLED panels for the 2026 MacBook Pro series

  • Technology Highlights:

    • Tandem OLED doubles screen lifespan and brightness

    • Integrates LTPO technology to reduce power consumption and enhance refresh rate adaptability

    • The 8.6-gen line can cut 138 units of 15.6-inch panels per batch, 2.5 times that of 6-gen lines (54 units)

2. BOE Technology Group (BOE): Stable Layout of China’s Panel Giant

  • Technology Route: Same as Samsung, adopting FMM + Tandem OLED technology

  • Production Line Plan: Announced investment in late 2023; expected to "light up" (start initial operation) in H1 2026

  • Market Strategy: Leveraging experience in supplying panels via 6-gen lines, it has secured partnerships with multiple brand clients, forming a solid customer base

III. FMM-free Camp: The Innovative Path of "Disruptors"

1. Visionox Technology: Pioneer of ViP Technology

  • ViP Technology: Visionox Intelligent Pixelization, a mask-free technology that replaces FMM with photolithography

  • Technology Breakthroughs:

    • Pixel density reaches 1,700-2,000 ppi, far exceeding the FMM upper limit of 300-600 ppi

    • Aperture ratio hits 69%, compared to only ~30% for FMM, boosting brightness by 4x (from 1,500nit to 6,000nit)

    • Lifespan extends 6x (from 15,000 hours to 90,000 hours), and water-oxygen barrier capability improves 3x

  • Yield Progress:

    • Yield rate of smartwatch panels exceeds 90%, and that of smartphone panels reaches 60% (on 6-gen lines)

  • Production Line Construction:

    • The Hefei 8.6-gen ViP production line was capped in October 2025volume production will start in Q1 2027

    • Total investment is approximately RMB 55 billion; monthly capacity remains undisclosed

2. TCL Huaxing Optoelectronics: Firm Bet on Ink-Jet Printing

  • IJP Technology: Ink-Jet Printing, which mixes organic materials into a solution and directly "prints" it onto substrates

  • Technology Advantages:

    • Material utilization rate exceeds 90%, compared to only ~30% for FMM, reducing material waste by approximately 66%

    • Simplified process flow; equipment investment is about 43% lower than that of FMM

    • The only OLED technology to achieve Real RGB Stripe arrangement, delivering clearer text display

  • Production Line Plan:

    • The Guangzhou 8.6-gen IJP production line broke ground in November 2025mass production will start in Q4 2027

    • Total investment is RMB 29.5 billion, with a designed monthly capacity of 22,500 substrates

V. Market Prospects and Competitive Dynamics

1. Market Size Forecast

  • IT OLED Market: From USD 2.5 billion in 2024 to USD 8.9 billion in 2029, with a CAGR of 28.6%

  • Laptop OLED: CAGR of 33% from 2023 to 2030

  • Total IT OLED Demand (2023-2028): Expected to reach 60 million units, with a CAGR of 46%

2. Current Competitive Situation

  • FMM Camp Leads: Dominates the market with mature technology, high yield, and solid customer relationships (e.g., Samsung’s exclusive Apple order)

  • FMM-free Camp Gathers Momentum: Despite challenges in yield and materials, its cost advantages (40-50% lower equipment investment) and performance potential (high resolution, high brightness) have attracted significant market attention

  • Key Variables:

    • The FMM camp needs to address high costs and material waste

    • The FMM-free camp must overcome bottlenecks in large-sized panel yield and material performance

    • Apple’s orders may become a bellwether for technology route selection

VI. Future Outlook: The Ultimate Showdown of Technology Routes

Short-term (2026-2027): The FMM camp will lead the market with first-mover advantages and Apple’s orders; Samsung’s 8.6-gen line will dominate the high-end IT OLED market

Mid-term (2027-2029): FMM-free technology will gradually mature; Visionox and TCL Huaxing’s 8.6-gen lines will start mass production, and cost advantages will begin to emerge, potentially increasing their market share

Long-term (2030+):

  • If FMM-free technology solves yield and material issues, it is likely to disrupt the traditional FMM route with dual advantages in cost and performance

  • The FMM camp may maintain competitiveness through further optimizations (e.g., more advanced Tandem technology)

Ultimately, the two technology routes may form a differentiated coexistence pattern: FMM focusing on the high-end, high-yield market; FMM-free covering the mid-to-high-end and large-sized panel markets with its cost advantages

Note: The above analysis is based on the latest public information as of October 2025; uncertainties remain in technological development and market dynamics.
