Since the release of Apple's latest smartphone, the iPhone X, which features an OLED display, the mobile phone market has been in a frenzy. Major manufacturers have quickly adopted OLED screens in their flagship devices, drawn by the superior color contrast and the sleek, full-screen design that appeals to consumers. As a result, smartphones equipped with OLED panels are becoming increasingly popular among buyers.
However, the current supply of small-sized OLED panels is largely dominated by South Korean companies. Samsung Display, the world’s leading producer of small OLED panels, holds over 97% of the global market share. Despite its massive production capacity—reaching hundreds of millions of units annually—it struggles to meet the growing demand from both its own smartphone lineup and Apple's iPhone X.
In response to this shortage, Chinese mobile phone manufacturers have significantly ramped up investments in OLED technology over the past two years. With ample capital in the mainland market and government support for new display technologies, it’s expected that multiple companies will launch new AMOLED production lines. Companies such as BOE, Tianma, Huaxing Optoelectronics, Hehui Optoelectronics, and Guoxian Optronics have all expressed interest or already begun exploring the OLED field, aiming to challenge the dominance of Korean firms.
That said, the development of AMOLED technology is not without challenges. High barriers exist, including the need for advanced backplane production capabilities, as well as complex evaporation and packaging processes for organic light-emitting layers. For example, evaporation equipment is still largely sourced from Japanese and South Korean suppliers, with Canon Tokki’s 6th-generation Half Cut machines being highly sought after by panel makers.
It’s encouraging to see that BOE’s Chengdu OLED production line is expected to begin low-volume production by the end of October, potentially supplying domestic smartphone brands. This could break Samsung’s monopoly on OLED screens for smartphones and mark a turning point in the industry. According to recent reports, Apple has already visited BOE and is considering using its OLED panels in future Apple Watch models, with potential integration into iPhones down the line.
