China’s TCL has unveiled a 65-inch 8K resolution OLED panel prototype at its own conference in China on Tuesday.

The prototype was developed by its display panel subsidiary CSOT, together with JOLED, and manufactured using the inkjet technology, TCL said at its conference dubbed 2021 TCL Huaxing Global Display Ecological Conference.

TCL COO Zhao Jun said during the conference that the company will become the first to have a Gen 8.5 (2200x2500mm) inkjet OLED production line.

However, the company didn’t say when the line, called T8 Project, will start being built.

Earlier, TCL had said it planned to start construction this year with production starting in 2024. The line was to be built a Guangzhou and a Gen 8.5 inkjet printing OLED line.

In August, during its conference call for its latest quarter, the company had said the plan was on schedule.

Last year in June, CSOT bought a 10% equity stake in JOLED for 30 billion yen, adding that the pair would co-develop an inkjet printing OLED production technology for the following three years.

Chinese media China-led.net had reported back in June that the pair’s project was being delayed due to unspecified problems.

It remains to be seen whether TCL will be able to commercialize its OLED technology on time. Inkjet technology can increase production efficiency but as the characteristics of materials are changed so that they can sprayed, this could lower the luminance of the OLED panel.

LG Display, currently the sole manufacturer of large-sized OLED panels, uses vacuum deposition instead of inkjet due to this reason.
