According to the latest display industry research report by TrendForce, OLED technology continues to expand its market footprint due to its advantages such as self-emission, high contrast, and slim form factor. Its adoption remains primarily concentrated in small-size applications like smartphones, while its penetration in the large-size segment has been constrained by cost and production capacity, resulting in slower growth. In contrast, the medium-size segment—comprising monitors, laptops, tablets, and automotive displays—is witnessing a new wave of market competition as consumers increasingly demand high-end display quality.

TrendForce forecasts that OLED monitor shipments will grow by 80.6% year-over-year in 2025, raising OLED’s penetration in the overall monitor market to 2%, with potential to reach 5% by 2028. In response to this growth trend, Visionox and TCL CSOT are not only continuing to develop FMM OLED, but are also entering the arena with differentiated technologies: Visionox with ViP (Visionox intelligent Pixelization) and TCL CSOT with inkjet printing OLED, setting themselves apart from Korean brands that have long focused on vapor deposition technologies such as QD-OLED and WOLED. By the end of 2024, TCL CSOT began integrating its self-developed, mass-produced printed OLED products into the medical monitor market. At SID Display Week in May 2025, the company showcased a comprehensive printed OLED product line, spanning sizes from 6.5 inches to 65 inches.

TCL CSOT Begins Mass Production of Printed OLED Medical Monitors; Visionox to Adopt ViP Technology in New Production Line

Compared to the more mature vapor deposition-based FMM OLED technology, printed OLED aims to break free from the limitations of FMM and vacuum processes. By using precise inkjet printing, this method improves material utilization and reduces equipment investment, potentially cutting costs by about 25% compared to comparable vapor deposition products. Industry players are hopeful this advantage will gain traction in the cost-sensitive medium-size market. However, printing technology still faces challenges in yield, pixel density, and reliability. Current printed OLED panels have achieved 326 PPI, sufficient for laptops and monitors, but further improvements in materials and device structure are necessary to enhance product lifespan and power efficiency.

TrendForce notes that in order to balance technological innovation with mass production, TCL CSOT is steadily supplying high-end smartphone and flagship laptop displays using its T4 Gen-6 FMM OLED line, while also gradually introducing printed OLED for applications such as medical and gaming monitors and laptops through its 5.5 Gen printed OLED line.

By the end of 2024, TCL CSOT began small-scale mass production of 21.6-inch medical-grade printed OLED monitors, marking the official commercial entry of printed OLED technology. Although large-generation printed OLED mass production lines have yet to be launched, the company appears to favor a strategically flexible approach, adjusting its production pace based on technological maturity and market opportunities, and exploring the optimal balance between vapor deposition and printing methods.

Similarly, Visionox, also part of the non-FMM camp, has been actively promoting the commercialization of its proprietary ViP technology in recent years. ViP utilizes photolithography to achieve pixel patterning, overcoming FMM limitations in size and resolution, while also enabling high aperture ratios and various pixel arrangements. Its new Gen-8.6 line in Hefei began construction at the end of 2024, with plans to incorporate both FMM and ViP technologies, targeting medium- to large-size markets.

TrendForce concludes that the actions of major manufacturers indicate that non-FMM technologies are gaining momentum. These alternatives to vapor deposition not only offer more diversified options but also reflect a future OLED market trend toward greater flexibility and cost-effectiveness.
