Key Takeaways
1. CSOT has developed a 14-inch camera-under-panel (CUP) OLED display showcased in the Lenovo Yoga Slim 9i at MWC 2025.
2. The new 21.6-inch 4K OLED panel achieves 99% DCI-P3 color gamut coverage using inkjet-printed (IJP) technology for consistent color accuracy.
3. TCL CSOT introduced a 350-nite QD-EL display for increased brightness, along with OLED panels utilizing fine metal matrix (FMM) technology for power efficiency.
4. A new 6.36-inch smartphone display features the world’s lowest-power integrated circuit, reducing power consumption by up to 31%, along with a 2.56-inch display for VR/AR headsets designed for minimal energy use.
5. CSOT is launching eye-protective displays, including a WQHD 120Hz circular polarizer and “moth-eye biomimetic” screens, alongside an anticipated 13-inch 144Hz 4K AI tablet screen as part of their Apex display lineup.
TCL’s subsidiary, China Star Optoelectronics Technology (CSOT), is behind the innovative 14-inch camera-under-panel (CUP) OLED display featured in the new Lenovo Yoga Slim 9i. They are showcasing this technology at MWC 2025, aiming to attract as much attention as possible.
Discovering New Displays
Visitors at CSOT’s booth, located at Stand 2M30 in Hall 2 of the Fira Gran Via, can also explore TCL’s new 21.6-inch 4K OLED panel, which achieves an impressive 99% coverage of the DCI-P3 color gamut. This display is produced using the cutting-edge inkjet-printed (IJP) method, which CSOT supports to ensure consistent color accuracy at various brightness levels. This consistency is made possible due to the “regular RGB pixel arrangement” that the IJP technique allows.
Innovations in Brightness
Additionally, TCL CSOT has enhanced brightness in IJP panels by introducing a new 350-nite QD-EL display, expected to be available in next-gen laptops soon. They have also presented OLED panels utilizing the fine metal matrix (FMM) technique at MWC, which claim to provide high brightness and variable refresh rates (VRR) while being more power-efficient for future PCs.
Trends in Compact Displays
The demonstration also includes a new 6.36-inch display designed for smartphones, which features the world’s lowest-power integrated circuit (IC) that promises to cut power consumption by as much as 31% compared to earlier LTPO models. Furthermore, the event showcases a 2.56-inch display for VR/AR headsets, designed for ultra-low energy use despite having a mini LED backlight that offers up to 40% greater luminous efficiency.
Eye-Protection and Future Tech
TCL CSOT is also unveiling a new WQHD 120Hz circular polarizer display focused on eye protection, along with “moth-eye biomimetic” screens for mobile devices. These will debut alongside a panel anticipated to be the first 13-inch 144Hz 4K AI tablet screen.
These displays are set to be part of CSOT’s upcoming lineup of Apex displays, which are designed to embody the principles of Amazing, Protective (for users’ eyes), Eco-friendliness, and the mysterious ‘X’ that represents the manufacturer’s vision for the future of display technology.
