Inkjet-printed OLED screens have long been a dream of the display industry, but no-one has successfully managed to produce IJP OLED screens at a mass-production level. That’s about to change.
TCL CSOT, the display manufacturing arm of TCL Technology, has revealed more details about the manufacturing process behind IJP OLED, and Trusted Reviews was on hand in Wuhan at DTC 2026, as TCL CSOT revealed its vision for the future of screens.
TCL CSOT started R&D on IJP OLED processes 13 years ago, and made the step in 2024 to mass production with the creation of its Gen 5.5 production line at its factory in Wuhan. This production line initially focused on its IJP OLED medical panels but has (recently) expanded to covering IT products and “consumer applications” (effectively laptops and monitor screens).
With manufacturing taking place at TCL CSOT’s Wuhan t12 and Guangzhou-based t8 production lines, the former is based on the development of “differentiated, high-value added products”, while t8 is set to come online in 2027 with what will be the world’s first Gen 8.6 IJP OLED production line focused on monitors, laptops, and tablets.

We’ve seen the first few IJP OLED screens emerge in 2026, with MSI’s unveiling of its 27-inch 4K 120Hz desktop monitor, along with Lenovo’s ThinkVision P27UL-40 professional monitor.
At TCL CSOT’s factory in Wuhan, we’ve also seen the display technology in 14- and 16-inch screens, as well as a foldable concept that used the technology, plus many more prototypes of where the screen technology could go next. TCL CSOT has big plans for IJP OLED.

But why is TCL CSOT (not to be confused with TCL Electronics on the devices side) so enthusiastic about IJP OLED displays?
Compared to more conventional OLED screens and QD-OLED, it believes that the way in which the IJP process deposits organic materials directly onto the substrate, IJP OLED is able to achieve material utilisation of over 90%. In simple terms, more of the organic materials are used and less is wasted compared to other methods.

Efficiency in terms of brightness is expected to be better, with other benefits including reduced blue light for a more comfortable viewing experience, reduced colour fringing, and as TCL CSOT manufactures panels, lowers costs when compared to traditional FMM (Fine Metal Mask) OLED production.
‘Traditional’ OLED isn’t going away but it looks like it has a new challenger. We’ll start to see in 2027 just how competitive TCL CSOT’s IJP OLED can be against LG Display’s OLED and Samsung Display’s QD-OLED.
