With its capacity set to rise 12-fold from 2020 to 2024, inkjet-printed (IJP) organic light emitting diode (OLED) display technology is set to enter mass production says research from IHS Markit.

IJP OLED 28Juen2019IJP OLED-based screens can solve the issue that has dogged the flat panel technology since its inception: affordability. The analyst says that in large-sized display applications such as TV, IJP OLED production is expected to be much cheaper than conventional white OLED (WOELD) manufacturing.

Compared with WOLED and FMM OLED, IJP requires lower initial investments in machinery and fab construction. It also boasts high material usage of 95% or better and has lower operating costs during production.

IHS Markit calculates in its Inkjet Printing for AMOLED Technology and Market Report 2019 that when producing a 65-inch, 4K TV on a Gen-10 line, IJP can potential cut costs by 15–25% compared with WOLED. In the small- and mid-size display market. IJP OLED could reduce production costs by about 20% compared with the fine metal mask (FMM) OLED method used in the production of 13.3-inch panels on Gen-6 production lines.

The survey states that the starting gun for the IJP OLED market will sound next year, when Japan-based JOLED Inc. becomes the first suppler to make the switch from trial manufacturing to full mass production. Chinese manufacturers will quickly follow suit, investing in volume manufacturing lines in 2020 and 2021, while other panel manufacturers will join the IJP OLED party in 2021 and beyond.

It calculates that global capacity will increase to 1.3 million substrates in 2024, up from 105,000 in 2020, according to the high-end forecast scenario presented in the Inkjet Printing for AMOLED Technology and Market Report 2019. Measured in terms of area, capacity will rise to 7.3 million square meters in 2024, up from 209,000 in 2020.

“In recent years, IJP has attracted the attention of panel makers due to its strong potential to reduce the cost of OLED production,” said Chase Li, senior analyst at IHS Markit. “Despite years of competition with LCDs in the market for high-end displays of all sizes, OLED market penetration remains limited because of its expensive production costs. However, IJP has the potential to dramatically reduce manufacturing expenses, making OLEDs more cost-competitive with LCDs in products including televisions and displays for computers and tablets.”
