At the business forum of K-Display 2025, held from August 6-9, China’s TCL CSOT said it will announce its investment plans for an eighth-generation inkjet OLED production line. The project, dubbed the “T8 Project,” is planned to begin trial production in June 2027, with equipment delivery targeted for September 2026. The initial production capacity is expected to be 15,000 sheets per month in the first phase. The investment is seen as a significant move to challenge the dominant position of South Korean companies in the large OLED panel market.

 The Inkjet Printing method adopted by TCL CSOT has a number of advantages over the Vacuum Deposition method currently used for large OLED production.

  • Cost and energy efficiency: The process can be completed in a low vacuum environment, significantly reducing equipment costs and energy consumption.
  • Material utilization: Since the organic material is ‘printed’ directly onto the substrate, there is less material waste, resulting in high material utilization.
  • Large substrate production efficiency: It is especially economical for large TV panels such as 65-inch and 77-inch.

One of the main technical challenges with inkjet OLEDs has been the lifetime of blue OLEDs, but TCL CSOT has made significant improvements. The company says its blue lifetime, which was just 40 hours in 2020, is now 400 hours, a tenfold improvement. In addition, the resolution has exceeded 350 PPI, which can meet the needs of high-performance tablets and laptops; the aperture ratio has been increased to three times that of conventional FMM (Fine Metal Mask) OLEDs to reduce power consumption; and the size of blue subpixels has been reduced to be similar to red and green, improving display quality.

Meanwhile, the printing equipment for the 8th generation OLED inkjet line is likely to come from Panasonic Production Engineering. Panasonic Production Engineering announced at SID 2025 that it has developed an 8.5-generation machine with a 1 pL (picoliter) inkjet head and 350 ppi resolution. The machine achieved an accuracy of 4.6 µm, exceeding the target accuracy of 5.8 µm, demonstrating the possibility of stable mass production of large substrates. The expected equipment configuration will consist of a Hole Injection Layer, Hole Transport Layer, and printing equipment for RGB pixel printing, as well as equipment for tandem OLEDs.  Panasonic’s equipment enables the production of high-resolution displays through high-frequency jetting (20 kHz) and droplet volume control as fine as 1.0 pL, which are key technologies for improving the productivity of the inkjet process. The company also reports that production stability is enhanced through a sophisticated system that compensates for thermal deformation and micro-alignment errors.

Inkjet OLED technology still has many challenges to overcome. While current technology has improved device lifetime, there is ongoing debate about whether it has achieved sufficient lifetime for commercialization. There are also limitations that make it difficult to implement tandem structures for high brightness and low power consumption. These challenges are directly related to the yield of the production line and require continuous technology development for successful mass production of inkjet. Nevertheless, TCL CSOT’s technological advancements show that inkjet OLEDs are getting closer to reality.

If TCL CSOT’s eighth-generation inkjet OLED investment materializes, it will pose a direct challenge to the mid- to large-sized OLED market dominated by South Korea’s Samsung Display and LG Display. Currently, these two companies rely on a costly vacuum deposition process, which keeps OLED TV prices high. Mass production using inkjet technology can bring cost competitiveness, which will significantly reduce the price of OLED TVs and increase market penetration. Furthermore, the technology is expected to impact not only the TV market, but also the laptop, tablets, and professional monitor markets. Inkjet technology can become an important steppingstone for China’s display industry to secure technological leadership in the OLED field, following LCD.

At the business forum of K-Display 2025, held from August 6-9, China’s SIDTEK discloses OLEDoS mass production status and future expansion strategy. In addition to announcing the start of mass production at its Wuhu facility, SIDTEK also announced that it has completed the groundbreaking of an additional factory and is preparing for a third facility. Amidst active competition from local governments to build OLEDoS mass production plants, SIDTEK has made it clear that its business progress in China should be based on “breaking ground and bringing in equipment” rather than announcing “contracts,” and plans to rapidly expand its production base with multi-base operations.

The pace of expansion in the Chinese ecosystem is also accelerating. SIDTEK explains that it has formed a “three-company simultaneous mass production” structure with BOE and SEEYA. Goertek, a set company, is also reportedly looking into the possibility of investing in the deposition process to directly control the display, which is the key to VR costs. The combination of these moves could lead to a production capacity scenario of tens of thousands of sheets per month for 12-inch in the medium term. The strategy is to use the power of scale to lower costs and speed up development capacity.

The speaker posed the question, “If OLEDoS is such good technology, why aren’t there any buyers around?” He emphasized the realism that large-scale facility investment should be judged by production volume, which is “can it be sold like a cell phone,” and that from a manufacturing perspective, demand validation and profitability should come first.

In-house design of backplane semiconductors was presented as a key solution to low yields that affect production prices. The diagnosis is that the low yield of Micro-OLEDs is not only due to technical difficulties, but also to unclear responsibility for defects that occur in the structure where the backplane (semiconductor) and panel are separated, and delays in improvement. “We need to bring the semiconductor inside and close the defect analysis and improvement loop,” SIDTEK emphasized. In China, vertical integration is spreading across the industry, with SEEYA investing in the wafer stage to optimize integration, and BOE preparing to enter the market with existing line capacity.

The product and market strategy is focused on “lightweight AR” in the near term. The speaker is skeptical of the “full screen all the time with glasses” scenario and predicts that AR will first be popularized for simple information such as navigation and notifications. As a result, optimizing backplane chips (BPICs) and optics, focusing on power consumption, visibility, and uniformity, rather than racing to ultra-high resolutions, is a challenge. Balancing realistic price points and ease of use will be key to early adoption, he said.

Judgments were also shared on the display technology axis. In VR, fast LCD, glass-based OLED, and OLEDoS are competing, with glass-based OLED, with its size scalability and optical simplification advantages, likely to emerge in the low-end and entry-level segments, while OLEDoS will share the role at the high-end. In the AR, the view was that LCoS, OLEDoS, and LEDoS will coexist, but that the volatility of the OLEDoS position should be noted, leaving open the possibility of a shift to LEDoS if ultra-high resolution is not a requirement.

During the on-site discussion, it was suggested that “VR devices have the potential to become widespread if lightweight and convenient designs can be achieved,” and that AI-based image processing combined with interaction will serve as a catalyst for this development.

SIDTEK’s announcement reaffirms its realist strategy centered on “real mass production factories” and “securing profitability”. The company plans to build credibility with multi-location mass production, speed up learning to improve production yield and defects with in-house design of backplane semiconductors, and open up the market with design and process optimization tailored to the lightweight AR segment, where near-term demand is gathering. Despite demand uncertainty in China, SIDTEK is responding with a conservative, execution-focused expansion strategy, as government-led investments and vertical integration among companies continue to drive the “game of scale” in the country.

At the K-Display 2025 Business Forum held from August 6 to 9 last week, Seongchan Cho, Vice President of Samsung Display, delivered a presentation titled “Display Paradigm Shift with AI,” explaining that, against the backdrop of evolving usage patterns across smartphones, tablets, and smart monitors and the advancement of communications and cloud infrastructure, the trend of “carry small, view big” is spreading and displays are being redefined as the core of the next-generation human–machine interface (HMI).

He noted that OLED has achieved major advances in perceived image quality—such as contrast, response, and color reproduction—and that it is now time to leap forward into a stage of intelligent optimization that simultaneously improves power, thermal, optical, and algorithmic performance. In particular, he outlined three clear pillars for AI.

First, with AI-designed OLED materials, the company will accelerate materials discovery and property prediction to improve key metrics such as lifetime, efficiency, and color purity more rapidly. Second, in panel architecture optimization, AI-driven design and simulation will shorten multivariable trade-offs across light extraction, encapsulation, and color conversion. Third, under “AI on Display,” the company will emphasize a strategy that dynamically operates features for health, security, and power saving by recognizing usage context. Power optimization and perceived user quality were also central messages.

The company introduced an approach that reduces unnecessary power consumption through control of the off-pixel ratio (OPR) and region-specific frequency optimization, while structurally lowering optical losses such as polarization loss. At the same time, based on the concept of “perceptual image quality”—that contrast and color optimization determine readability and fatigue even at the same luminance—the company stated it will comprehensively enhance contrast, color accuracy, and uniformity to elevate perceived sharpness.

The roadmap for the XR era was also made clear. By combining high-density, high-brightness OLEDoS microdisplays compatible with lightweight optics (such as pancake lenses) with ultra-low-latency driving and improvements in viewing angle and uniformity, the company aims to reduce fatigue in long-wear scenarios, while presenting practical use cases in which multimodal inputs—such as eye gaze, hand gestures, and voice—are processed by on-device AI. This aligns with the direction of “smart displays,” which integrate and optimize power, thermal, optical, and algorithmic factors under device battery constraints.

The health, security, and power-saving focus of “AI on Display” was also presented in concrete terms. On the health front, the company pointed to organic photodiode (OPD)-based biosignal sensing and adaptive contrast/color temperature control to reduce eye strain; on security, smart privacy displays and risk detection based on gaze and presence sensing; and on power saving, dynamic operation that reflects content, environment, and user status to maximize battery efficiency.

The company also demonstrated strong commitment to environmental and safety (ESG) goals. It is pursuing a roadmap to substitute hazardous gases and chemicals used in silicon-oxide-based multilayer structures with safer substances and to phase out and replace high-performing yet environmentally burdensome materials such as PFAS. The company plans to raise environmental and safety standards in parallel throughout large-format, high-integration, and wearable expansion.

At its exhibition booth, Samsung Display showcased exhibits that concretize this vision. Through microdisplay engines/modules for XR, lightweight-optics-compatible reference designs, and interaction demos under the “AI on Display” concept—such as gaze-based focusing and variable-resolution/brightness driving—the company highlighted its capabilities in the integrated optimization of panels, optics, and algorithms.
