China has taken a proactive stance in the layout of high-generation LCD panel production lines. The investment in the 10.5 generation line has reshaped the global competitive landscape of the LCD panel industry. While TFT-LCD remains dominant, other display technologies such as OLEDs, QLEDs, printed displays, Micro LEDs, and laser displays are gaining traction. Guan Xudong, a professor at Peking University, emphasizes the need to guard against the impact of alternative technologies on liquid crystal displays. He advocates for increased focus on forward-looking technologies and non-liquid crystal alternatives.
OLED technology has benefited from significant state support, particularly in the production of LCD panels. Large-screen TVs are becoming increasingly popular, with 55-inch models now dominating the market and 65-inch models on the rise. Forecasts suggest that LCD TVs over 65 inches could account for 8.7% of the market in 2018, rising to 10% by 2020. In response, global panel manufacturers are investing heavily in ultra-high-generation LCD panel lines (10 generations or more). Following BOE and Huaxing Optoelectronics, companies like Foxconn, LGD, Weike, and CEC are also planning to invest in similar lines. There will be eight such lines worldwide.
Compared to the progress in LCD panels, the domestic ultra-high-generation OLED sector remains nascent. However, domestic panel makers are exploring printed OLED technology, which holds the promise of reducing costs. As Zhu Changchang, a senior consultant at TCL's Research Institute, explains, while small-sized OLEDs are feasible through vapor deposition, large-sized OLEDs face low yields and high costs. Samsung has already abandoned this approach. Instead, printed OLEDs could offer a cost-effective solution. In 2012, Yan Xiaolin proposed printed displays as a crucial path to overcoming the limitations of large-sized OLED technology.
In 2014, Guangdong established the Printing Display Technology Innovation Alliance, bringing together industry leaders and university resources. A public R&D platform for printed OLEDs was launched, along with Guangdong Juhua Printing Display Technology Co., Ltd. Printed OLED technology is now a key focus of China's "13th Five-Year Plan," with national new material projects including it. In 2016, Guangdong Juhua collaborated with US firms like DuPont, Sumitomo Chemical, Nissan Chemical, and Cody to support their material and process needs.
Huaxing Optoelectronics, Guangzhou New Vision Optoelectronics, and Fuzhou University have successfully developed a 31-inch FHD printed OLED sample. Juhua's factory in Guangzhou Science City is nearing completion, with equipment commissioning underway and a test line set to open by the end of August.
While laser display technology is also making strides, it primarily involves downstream machine manufacturers. Over the past few years, laser TVs have seen rapid development. Brands like Hisense and Changhong, alongside newcomers like Xiaomi and Sony, are actively adopting laser TVs. Xu Lixin, a professor at the University of Science and Technology of China, notes that China's laser display technology rivals foreign competitors, excelling in optical engines and light efficiency technologies, whereas foreign firms lead in driver chips and semiconductor light sources.
Hisense's laser optical engine is entirely self-developed, with 70% of the TV's cost controlled domestically. Changhong has also accelerated its laser TV production line, aiming for an annual capacity of 150,000 units. The industry is moving toward full-color laser projection, synthesizing white light using narrow-band red, green, and blue lasers. Hisense plans to release full-color laser TVs next year.
Micro LED technology has gained considerable attention recently, driven by Apple's acquisition of LuxVue. Early research in Micro LED began in 2006, with the Hong Kong University of Science and Technology developing passive-driving flip-chip integration of Micro-LED arrays. Other breakthroughs include high-resolution Micro LED displays and collaborative efforts increasing pixel density.
Despite these advancements, China's LED manufacturers often focus on commercial markets rather than cutting-edge technologies like Micro LED. However, breakthroughs like GaN micro LED micro-display chips demonstrate China's potential.
Experts stress the importance of protecting and strengthening LCD technology. China's lead in large-size LCD panels, thanks to 10.5-generation production lines, ensures dominance in the short term. Yet, concerns persist about excess capacity. Promoting 8K broadcasts for the 2020 Tokyo Olympics and driving 4K/8K applications domestically could be viable solutions.
Liang Qingxin highlights the need to combine large size with high resolution. China should also enhance its industrial chain and address core technology challenges, such as avoiding patent disputes. OLEDs, despite their advantages, remain costly and technologically complex, limiting their market share. Printing technology offers a promising avenue for large-size OLEDs, though challenges remain.
Micro LED shows great potential in large sizes, with benefits like low power consumption and high brightness. Tu Menglong notes its superior indoor brightness compared to LCDs. Despite its challenges, including large-scale transfer technology, Micro LED remains a promising contender. China's focus on non-liquid crystal technologies and forward-looking research, especially in Micro LED, positions it well for future dominance.
