TCL's interest in OLED is growing, particularly inkjet-printed displays, with the company claiming "comprehensive breakthroughs in image quality, power consumption, and lifespan".

At the Omdia Korea Display Conference, TCL's display manufacturing arm, CSOT, delivered a keynote on the progress of inkjet-printed OLED, which uses large printers to produce the displays.

Ming-Jong Jou, Chief of the Technology Planning Center, highlighted the growth potential, noting that TCL CSOT is currently focused on ramping up production of medium-sized OLED displays for monitors and laptops, although the production method can also later be applied to OLED TVs.

The company will reportedly begin limited inkjet OLED production by the end of 2024.


Breakthroughs in printed OLED
TCL has previously showcased prototypes such as a 65-inch 8K OLED, a 31-inch 4K dome-shaped OLED, and a 14-inch 2.8K laptop OLED, which were apparently made possible by the recent breakthroughs.

- "TCL CSOT has achieved comprehensive breakthroughs in image quality, power consumption, and lifespan, elevating its performance to the level of mainstream display technologies," the company announced.

Specifically, it claimed that its printed RGB OLED now has "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".

It added that it has achieved a 20% reduction in total cost and that its printing technology is ready for more flexible production that can help shorten the product development life cycle by 30%.
