At Mobile World Congress in Barcelona, TCL CSOT demonstrated the latest display technologies focused on energy efficiency, not just higher resolution. The subsidiary TCL Technology presents Super Pixel technology for smartphones and shows progress in the production of OLEDs using the thin metal mask method, printed OLEDs and MLEDs under the APEX brand.
Super Pixel technology changes the location of pixels instead of increasing their number. TCL increases the number of sub-pixels by 1.8%, achieving WQHD SPR clarity while reducing power consumption by up to 25% through data processing optimization. The Real RGB configuration requires less bandwidth than SPR, which allows for up to 40% higher refresh rates.
The key bet is on OLED production by inkjet printing. TCL CSOT reports that it has spent more than a decade researching IJP OLED and started mass production on the G5.5 line in Wuhan in November 2024. Construction of the 8.6th generation plant in Guangzhou began on October 21, 2025, following an investment of $4.15 billion. Inkjet printing applies OLED materials without masks, reducing the risk of contamination, but scaling up the technology is difficult due to difficulties with drying control, production speed, and material limitations compared to vacuum evaporation.
TCL demonstrated concept devices to showcase the capabilities of printed OLED: a 28-inch trifold monitor with a 1.8 mm bending radius and 4.48 mm thickness, and a 14-inch laptop panel with a thickness of 0.77 mm and a weight of 77 g.
The competition in the production of large OLEDs is heating up. Samsung Display plans mass production on the Gen-8.6 FMM line in the second quarter of 2026, and the panels will be supplied for Apple MacBook Pro models. TCL CSOT is taking a different route with printed OLED to enter the same IT display market.
