We previously covered reports that TCL has begun transitioning to inkjet-printing of OLED panels, with the company slated to begin production by the end of this year. TCL has now highlighted its efforts at the Omdia Korea Display Conference, with Ming-Jong Jou, Chief of the Technology Planning Center, TCL CSOT, delivering a keynote on the subject.
Jou discussed the “significant growth potential” in inkjet-printed OLED, and claimed that TCL has achieved “comprehensive breakthroughs” in image quality, power consumption, and lifespan. Specifically, Jou highlighted that utilizing inkjet-printed OLED in conjunction with a side-by-side RGB structure, its new technology features “lower power consumption, with materials efficiency doubled, a 50% reduction in light loss due to internal reflection, and a 1.5 times improvement in light output efficiency. Lifespan has also been significantly enhanced, with an aperture ratio three times larger and material lifespan improved tenfold.”

The keynote noted that currently TCL is focused on utilizing inkjet-printing in medium-sized OLED displays for applications like commercial monitors and specialized medical products, highlighting the company’s 14″ 2.8K Hybrid OLED display, with a 2.8K resolution, over 99% DCI-P3 color gamut, and adaptive refresh rates ranging from 30 to 120Hz. Other applications, such as larger displays for commercial and consumer TVs, are being considered for the future.
