Coronavirus Decimates China’s Public Display Production

Organic light-emitting diode (OLED) technology has a number of advantages over liquid-crystal display (LED) when it comes to displays, including the ability to manufacture on substrates such as plastic.
OLED screens are made by spraying thin layers of ink-like substances onto a surface such as glass. The ink-jet application allows OLEDs to adhere to flexible surfaces such as plastic, paper or even fabric. According to market research firm IHS, demand for flexible OLED displays is expected to grow by more than a factor of four next year, with sales reaching nearly $100 million in 2014.
Following Samsung’s introduction of the first flexible organic light-emitting diode (OLED) products this year, global market revenue for flexible OLEDs will rise to $94.8 million in 2014, up from $21.9 million in 2013, according to a new report entitled “In-depth analysis for Technical Trends of Flexible OLED” from IHS Inc. The projected growth next year will equate to a 334 percent expansion from this year, paving the way for much larger sales in the future.
OLEDs represent a major segment of the larger flexible display market, which in the coming years will also include liquid-crystal display (LCD) and electronic paper (e-paper) technology.
“The buzz about flexible displays has been growing louder, ever since Samsung Display demonstrated its Youm line of bendable OLED products at the Consumer Electronics Show in January,” said Vinita Jakhanwal, director of mobile and emerging displays and technology at IHS. “Samsung is expected to begin shipping its first flexible OLED display—a 5-inch screen—in the second half of this year.”
Samsung’s initial product is likely to be a first-generation flexible display, employing a non-glass substrate that yields superior thinness and unbreakable ruggedness. However, such displays are flat and cannot be bent or rolled. Flexible displays are expected to eventually evolve into rollable and foldable OLED screens that are likely to be introduced after 2016.
Even so, it is too early for flexible OLED panels to fully replace conventional OLED screens. This is because the plastic substrate, thin-film encapsulation and other related technologies for flexible OLED remain immature for immediate application. Moreover, manufacturing processes are still being tested.
“A wide range of complementary technologies are under development to accelerate the advancement of flexible displays,” Jakhanwal said. “The success of the flexible OLED market will ultimately be determined by the maturity of the materials and manufacturing processes that will enable large-volume production at reasonable costs.”
