As the market for small and medium-sized AMOLEDs is on the market, Chinese manufacturers have to go through three tracks.
Since 2009, in just seven or eight years, mainland China has seen the construction and planning of more than ten LTPS AMOLED production lines, ranging from 5.5 to 6 generations. The possibility of new lines emerging remains high. Following the development trajectory of LCDs, China is now entering a new wave of AMOLED growth. However, this wave is largely dominated by South Korean manufacturers, with Samsung leading the charge. Thanks to years of technological accumulation and strong marketing, Samsung has established a near-monopoly in the small and medium-sized AMOLED market.
While Chinese panel makers have made significant progress in technology, they still lack industrialization experience and market insight, making it difficult for them to compete directly with Samsung. At present, the top priority for Chinese companies is improving yield rates. Another major concern is overcapacity, as many new production lines are being built without clear demand forecasts. Additionally, flexible display technology poses a significant challenge that remains unresolved.
The difficulty of AMOLED development is well known. Domestic manufacturers have set up several 5.5-generation lines, but low yields and limited capacity mean only a small number of products reach end users. According to Gao Xiaoping of Fufu Electronics, increasing AMOLED development speed is not easy. Samsung's success stems from long-term investment in algorithm development, including acquisitions of specialized pixel algorithm firms. Their continuous improvement in AMOLED processes is evident from the evolution of their flagship devices, such as the transition from Note3 to Note8.
Despite efforts, domestic companies still face challenges in scaling up production. Liang Xinqing from the China Optics and Optoelectronics Industry Association warned that while investing in AMOLED lines is positive, the real test lies in whether they can achieve mass production. If not, it could lead to serious overcapacity risks. Zhang Deqiang of Gu'an OLED emphasized a strategic approach: conducting basic research first, followed by pilot testing and then mass production. This method helps reduce risk by ensuring solid technical foundations before scaling up.
Companies like Harmony and Visionox have taken different paths, but all share a common goal: improving yield and mastering key technologies. Tianma, for example, split its teams to focus on both LTPS and later-stage AMOLED R&D, eventually achieving mass production. Despite these efforts, overcapacity remains a pressing issue. Ouyang Zhongcan from the Chinese Academy of Sciences predicted a massive increase in AMOLED production capacity, from 600,000 square meters in 2017 to 25.89 million by 2022—a growth of over 400%.
However, the smartphone market is not expected to grow at the same rate. Liang Xinqing noted that even if global smartphone shipments reach 2.5 billion by 2020, only half would use AMOLED screens, leading to potential oversupply. To avoid this, experts suggest exploring new applications, such as flexible displays. A flexible phone could require three 5.5-inch AMOLED panels, effectively replacing an iPad mini. This could help absorb excess production capacity.
Still, some industry leaders believe oversupply is a natural part of market evolution, similar to what happened with LCDs. Liu Qingquan from Tianqing Market argued that while supply may exceed demand temporarily, it’s part of the process of product commoditization. For now, panel makers are more focused on improving technology and customer service than worrying about supply-demand imbalances.
The biggest challenge remains flexible display technology. Although there is great enthusiasm around flexible AMOLED, especially due to wearable devices, the technology is still in early stages. Cheng Zhanglin, who previously worked at Kodak, pointed out that developing flexible AMOLED is far more complex than rigid versions. Current bending tests show flexibility up to 300,000 cycles, but real-world data is still lacking.
Most manufacturers are still demonstrating samples, but moving from sample to commercial product requires significant breakthroughs. Samsung has made progress with flexible plastic substrates, but full-scale adoption is still far off. Xie Qinyi from IHS believes that flexible OLEDs require constant exploration to eliminate technical blind spots. One of the main issues is the bending mechanism, though Samsung claims that the real challenge lies in integrating flexible touchscreens.
As the AMOLED industry moves forward, the path ahead is challenging but promising. With continued innovation and strategic planning, Chinese manufacturers aim to close the gap and carve out a stronger position in the global market.
