China’s display makers are ramping up production capacity of flexible OLED smartphone screens this year to challenge the South Korean display makers currently dominating Apple and Huawei supply chains.

State-backed BOE Technology Group has already been chosen over Samsung Display to provide flexible organic light-emitting diode displays for the Mate X, Huawei’s first foldable phone, though industry watchers caution that the quality of up-and-coming Chinese display makers remains an open question.

BOE compatriots China Star Optoelectronics Technology, or CSOT, Tianma Microelectronics and Visionox are also aggressively expanding capacity as China seeks to develop world leaders in cutting-edge display technology as part of Beijing’s Made in China 2025 policy. 

Rapid expansion of China’s state-backed display makers could spark a brutal price war, hitting the margins and market share of existing leaders, as happened in the LCD market, say analysts.

“This year is an important year for Chinese display makers considering the massive new OLED capacity from them,” Eric Chiou, a veteran tech analyst at WitsView, told the Nikkei Asian Review.

“We foresee they will start to have significant impact on South Korean players, especially to affect Samsung Display’s dominance from the first half of 2020 at the earliest,” Chiou said.

Flexible OLEDs are essential for curved-corner smartphones, now the industry’s mainstream design. They are also required for foldable phones, an innovation seen as key to reviving growth in a slowing smartphone market.

BOE, which became the first Chinese company to produce flexible OLEDs for smartphones in 2017, plans to have an additional capacity of 45,000 panels per month by the end of this year. Its total capacity will rise to around 90,000 OLED panels, according to Taipei-based research company WitsView, citing supply chain checks.

On a monthly basis, the flexible OLED display capacity of BOE alone for smartphones will exceed second-ranked LG Display’s 60,000 panels and narrow the gap with top player Samsung Display’s 165,000 panels this year.

Even without the bendable feature, the better contrast and higher brightness of OLEDs makes them a top choice for premium models, such as the iPhone Xs series, Huawei’s Mate series and Samsung Electronics’ flagship Note and S series.

The OLED supply has for years been led by Samsung Display, an arm of the South Korean device maker, owing to high technology and investment barriers to newcomers. Building up the necessary capacity requires tens of billions of dollars in capital spending.

But the playing field is changing as China’s government-backed display makers, including BOE, CSOT, Visionox and Tianma Microelectronics, gain ground in terms of technology and capacity.

“The flexible OLED will become the mainstream display technology,” Li Dongsheng, chairman and CEO of leading Chinese television market TCL, said in a keynote speech at the China Information Technology Expo in Shenzhen on April 9. “China will accelerate technology development to be the world-class leader in the next few years,” added Li.

State-backed TCL is the parent company of CSOT.

CSOT’s first sixth-generation flexible OLED plant in the Chinese city of Wuhan is scheduled to begin mass production in May. The initial production line is set for 15,000 panels per month, with a second line to start operation in the first quarter of next year, the company told Nikkei. Tianma and Visionox Technology, meanwhile, will have new OLED capacity of 15,000 and 25,000 panels per month, respectively, when they begin mass production later this year.

Tone Wu, Tianma’s deputy director for marketing, acknowledges that the foldable smartphone market is in its infancy, and that high retail prices and manufacturing costs deter both consumers and producers. “However, we [Chinese display makers] are betting on flexible OLEDs as we believe it will be the future mainstream spec for smartphones and we need to secure our market positions as soon as possible,” Wu told Nikkei.

“With the government’s support and Chinese smartphone companies’ desire to foray into foldable phones, this is the right track to invest on [flexible OLED] and we are in the leading group with South Korean peers,” Wu said.

However, South Korean display makers remain far ahead in terms of quality, meaning it will take time for Chinese companies to catch up despite their ambitious capacity expansions. 

Meanwhile, South Korean prosecutors last November indicted 11 executives at a Samsung supplier group on charges of leaking OLED technology to four unnamed Chinese display rivals. More
