TCL CSOT Inkjet Printing OLED at Display Week 2025: 65" 8K, 21.6" Mass Produced Oxide TFT RGB Stripe

TCL CSOT showcased its progress in inkjet printed OLED (IJP OLED) technology at Display Week 2025, with a focus on cost-effective high-resolution displays. Leading the development is a 65-inch 8K IJP OLED TV, built using a printing process similar to office inkjet printers, where RGB inks are deposited as microdroplets directly onto a driving circuit. This additive process eliminates the need for photolithography masks, offering material efficiency and design flexibility. While mass production of this model is still under consideration due to the competitiveness of LCD pricing, the technology already demonstrates around 20% cost savings over conventional OLEDs. The company's official site provides more details: https://www.csot.tcl.com/en/ --- Thanks to SEL Semiconductor Energy Laboratory Co., Ltd. https://www.sel.co.jp/en/ for being my Display Week 2025 sponsor.

TCL CSOT mentioned that, with a Gen 8.5 line, sizes up to 110 inches could be achievable. The technology is also being applied to smaller panels with high pixel density, such as a 21.6-inch 4K display already in mass production for medical imaging applications like ultrasound and CT systems. This panel boasts higher resolution than the 65-inch 8K model due to its tighter pixel pitch, underlining the versatility and precision of the inkjet process. For creative professionals and gamers, a 27-inch IJP OLED monitor is under joint development with commercial partners. Featuring 120 Hz refresh rate, fast response time, and high contrast, the display is targeting affordability and performance for prosumer use cases. TCL CSOT aims to offer superior image quality and improved color rendering without color fringing, thanks to its real RGB stripe pattern. This approach avoids the subpixel rendering issues seen in PenTile arrangements, maintaining sharpness especially in text and UI elements. One standout feature is the oxide TFT backplane, which contributes to reduced power consumption. TCL CSOT claims additional efficiency gains at lower refresh rates—up to 10% savings compared to non-oxide backplanes. The oxide design supports power-sensitive applications like laptops and tablets, and contributes to longer battery life without sacrificing display quality. This makes IJP OLED a competitive option for portable electronics in addition to fixed displays. In notebook applications, TCL CSOT has achieved a resolution of 242 PPI with smooth character rendering and no color fringing. A further prototype panel reaches 326 PPI—approaching “retina” display territory—with a consistent RGB stripe layout, enabling accurate font rendering and graphic detail without subpixel color artifacts. These patterns are naturally suited to the inkjet process, which favors line-based printing and uniform subpixel dimensions. TCL CSOT also demonstrated a tablet display using the same printed OLED technology with a touch layer added on top. The touch integration posed no interference challenges, reinforcing the practicality of IJP OLED for interactive devices. This reinforces its viability across a broad spectrum of consumer electronics, from large format TVs to portable pads and laptops. An important technical milestone this year was the improvement in material efficiency and manufacturing yield, which are critical for approaching large-scale mass production. The blue OLED subpixel—historically the weakest link in terms of lifespan—has shown marked improvements, passing internal aging tests. Lifetime expectations are now estimated at 10 years for TVs and around 5 years for notebooks, assuming typical usage patterns. Burn-in, a common concern with OLEDs, is being addressed through compensation algorithms that dynamically adjust driving currents and mitigate image retention. With more than a decade of dedicated R\&D behind it, and significant capital invested, TCL CSOT appears poised to bring inkjet printed OLED closer to widespread commercialization, offering a blend of performance, manufacturability, and cost-effectiveness.
