Smartphones, televisions, tablets, portable gadgets, vehicle screens to be developed

Chinese display panel and home appliance manufacturers are betting big on next-generation cutting-edge solid-state display technologies, which have huge application potential in smartphones, televisions, tablets, wearable gadgets, vehicle-mounted displays, virtual reality and augmented reality.

These new display technologies use organic light emitting diodes (OLED) and micro light emitting diodes (micro LEDs). Industry insiders have said that compared to traditional liquid crystal display (LCD), new display technologies show great improvements in image contrast, brightness and color spectrum, accelerating thus further upgrading the display industry.

Domestic display panel suppliers such as BOE Technology Group Co Ltd and Visionox Technology Inc are doubling down on flexible active matrix organic LEDs or AMOLED, which is a more flexible type of OLED.

BOE has launched a number of innovative and world-leading flexible display screens, which have been applied in flagship products for high-end smartphones, such as Honor’s Magic 3 series and Vivo’s iQOO 8. .

Beijing-based market researcher Sigmaintell Consulting said that BOE shipped around 25 million flexible OLED smartphone panels in the first half of the year, up nearly 70% year-over-year, ranking in leading the flexible display industry in the domestic market.

The company has three flexible sixth-generation AMOLED production lines. It started mass production of flexible panels at its factory in Chengdu, Sichuan Province, in October 2017. The panels have already been used by more than 10 smartphone manufacturers.

The company’s second line in Mianyang, Sichuan Province began mass production in July 2019, while work on its third factory began in Chongqing in 2018.

“With the development of 5G, big data and cloud computing, billboards will change lifestyles and improve visual experiences,” said Xu Fengying, vice president of Visionox, adding that advanced technologies will boost applications for flexible displays.

Xu said AMOLED will have wider applications in mobile phones, computers and smart wearable devices. Its screens have been used by smartphone giants like Xiaomi, Oppo and Huawei.

Visionox’s AMOLED display screen production line in Gu’an, Hebei Province started operation in 2018. It can produce 30,000 glass substrates every month and meet the demand for foldable screens. high-end for 90 million smartphones. It started building its second flexible AMOLED production line in Hefei, Anhui Province, in December 2018.

“With the arrival of the 5G era, flexible AMOLED products have broad application scenarios due to their bendable and flexible characteristics. They will bring different and high quality experiences to consumers, ”said Chen Jun, vice president and chief analyst of Sigmantell. .

According to market research firm Omdia, global shipments of OLED panels for smartphones will reach 812 million units in 2022, an increase of 38.8% from the 585 million units estimated in 2021.

In terms of OLED offering, Samsung Display is expected to remain the leading player in the market next year, but its market share is expected to decline and its dominant position could be called into question as Chinese panel makers have entered the OLED market. small and medium size and have improved production skills, said Omdia.

Wang Xiaoya, analyst from Sigmantell’s mobile department, said that besides smartphones, the proportion of OLED panels used in smart wearable devices, tablets, computers, laptops, televisions and vehicle-mounted displays does has stopped increasing in recent years.

In addition, Chinese TV maker Skyworth Group has been relying on large OLED TVs and producing OLED TVs in partnership with South Korean panel maker LG Display since 2013. At present, LG Display is the only company. capable of mass-producing medium-sized large OLED displays to the world.

Last year, the direct revenues of the new display industry in China reached 446 billion yuan ($ 69 billion), accounting for 40.3% of the global total and ranking first in the world, Wang said.
