Technology is getting mature, and the price has become a barrier to OLED lighting.

As the capacity of AM OLED panels continues to expand, the application tentacles continue to extend outward. In the past, OLED lighting, which was considered to be overpriced, is also eager to enter the end market. The flexible OLED panel process will be introduced under the advantages of surface design and dimensional flexibility. In the high-end automotive taillight market.

At the time when European, Japanese and Korean major manufacturers increased their production of OLED lighting, the first flexible OLED lighting production line jointly built by Taiwan Industrial Technology Research Institute and Taiwanese manufacturers also entered the trial production. The monthly production capacity is about 700 pieces and it is expected to enter a small production in 2017.

Under the impact of overcapacity, LED lighting prices have been smothered in recent years, and OLED lighting is limited by the excessive price difference with LED lighting, and has never been able to enter the sweet spot of price, but each factory is still actively promoting OLED lighting ready to go. .

According to the Institute of Electro-optics of the Industrial Technology Research Institute, OLED lighting is expected to enter the popularity market from 2019 to 2020, and it is expected to enter the lighting market for home lighting. As for the Japanese and Korean research and development units, it is estimated that the OLED lighting market will be 2020. Look at the $1 billion.

Recently, European companies such as Audi have joined the promotion of flexible OLED panels, including LED manufacturers Osram actively promoted the use of OLED panels in the automotive market; Japanese manufacturer Ko nica Minolta also took the lead in mass production of plastic substrates. The flexible OLED panel production line aims to see 50 billion yen in revenue in 2020.

In addition, LG Display also announced that it will invest in a new generation of OLED lighting production line of up to 200 billion won (about 167 million US dollars) in the Gumi Plant area of ​​Gyeongsangbuk-do. It is expected to be officially invested in the first half of 2017. Mass production.

Unlike the rigid OLED panels currently used by panel makers, the continuous roll-to-roll process developed by ITRI can not only break through the bottleneck of the effective cutting rate of existing hard panel processes, but also from the front-end production equipment and materials. To achieve localization, the production cost can also reach the advantage of 3 to 5 times the gap.

Wu Zhiyi, director of the Institute of Electro-optics of the Industrial Technology Research Institute, said that the small-scale trial production verification platform for OLED lighting built by the company uses thin glass (thinflimglass) substrates, and its production equipment and materials manufacturers are all working together from Taiwanese manufacturers. It is expected that 70% of the mass production line process will be completed in 2016, and it will enter the small-scale production smoothly in 2017. It will be the world's first flexible OLED panel production line using glass substrate process.

Hu Jiping, deputy director of the Institute of Electro-optics of the Industrial Technology Research Institute, said that OLED lighting is regarded as the fourth lighting revolution, but the current obstacle lies in how OLED lighting technology can provide affordable lighting prices. Currently, the price of OLED lighting on the market is still high, at 7cm. * In terms of size of 7cm, the price is about NT$1,000~3,000. Although the cost of OLED materials is high at present, with the increase in manufacturing and yield, production costs are expected to drop rapidly.

And because the luminous efficiency of OLED lighting continues to increase, the current luminous efficiency can reach 70~80lm/W, and the secondary optical design is not needed, so that OLED lighting has met the needs of household lighting, and it is expected that it will gradually gradually become 2019~2020. It is imported into the home lighting field and integrated from the application side to complement the LED lighting application.

Because flexible OLED lighting has characteristics such as natural light, no glare, high color rendering, and curved surface design, ITRI said that OLED lighting should be the last one, as OLED lighting technology matures. Connecting technology to end-application customers and highlighting its technical advantages, it will expand the cooperation of the lighting industry and present OLED lighting for use in medical aesthetics, automotive, building materials and home markets.
