OLED lighting technology quickly picked up the emergency layout of the plant

OLED (Organic Light Emitting Diode) display technologies have continued to develop, not only in the display screen (panel), but also in the new generation of lighting applications since 2011. It is estimated that by 2018, the global OLED lighting output value may reach 6 billion U.S. dollars, and relevant business opportunities should not be underestimated. At present, Taiwanese manufacturers include panel makers such as AU Optronics (2409), which has already invested in AMOLED active matrix organic light-emitting diode displays, and Chunghwa Picture Tubes (2475), and PMOLED makers such as PMOLED's subsidiary OLED and OLED glass (cum-ITO glass). , professional photoelectric glass) supplier Encore (3615), etc. have been laid out.

Although the OLED technology is applied to displays, the driving modes can be classified into passive matrix PMOLED and active matrix AMOLED. Among them, the AMOLED has continuous light emission, low power consumption, and life of the light emitting device. Such advantages as long, but the cost is higher and the process is more complicated. PMOLED has the advantages of lower cost, simple process, easy design change, etc., but it needs high voltage to drive and can only emit high-density light instantly.

However, when applied to OLED lighting, because the OLED technology is based on the same basis, and does not require the use of TFT substrates, therefore, whether AMOLED manufacturers or PMOLED manufacturers, have the ability to rapidly invest in the development of OLED lighting products. In particular, OLED and TFT-LCD panels are compatible with a certain degree (generally estimated 6-80%) process, therefore, including AUO, Chunghwa Picture Tubes, Toshiba Action Display (TMD), and LDK, Samsung Samsung, etc., in recent years All of them started the OLED lighting layout one after another, expecting to succeed in the panel business.

AUO entered the field of OLED lighting as early as 2010 and exhibited many results at FPD International in Japan. The company is currently using 3.5 generations of plant capacity, continuing to invest in OLED lighting patents and process technology, and has a small amount of trial production.

Huaying also uses its 4th generation line to develop OLED lighting technology, and hopes to further improve the uniformity, luminous efficiency, service life, and cost of OLED lighting by adding metal reference lines and OLED materials. According to the earlier plan, it is expected to start small-scale production in the second quarter of 2012 as soon as possible.

The OLED manufacturer Sic Bo under the Jude Group is currently focusing on PMOLED panels. However, the company has also invested in OLED technology to develop OLED lighting products. Currently, there are 6 production lines.

Not only Taiwanese manufacturers have embarked on the OLED lighting field, but mainland Chinese companies are actively working on the layout of OLED technology, from display applications to lighting applications. For example, the Chinese OLED company Nanjing Dijon Organic Optoelectronics signed an agreement and cooperation agreement with Hefei University of Technology in November 2011. It plans to invest RMB 980 million in the establishment of an OLED lighting production line, the fastest in the second quarter of 2012 will be 4 generations. Line production, the end of 2012 will mass production of the first batch of OLED lighting panels and lamps.

As for international lighting giants, they also aim to maintain their leading position in OLED lighting technology. For example, Panasonic Electric announced in October 2011 that the "Freedom Hill Station" of Tokyo Express Electric Railway will use OLED lighting devices produced by Matsushita Electric Works. , and is scheduled to be transformed in March 2012. Philips also stated in October 2011 that it has invested 40 million euros in establishing an OLED lighting production line in Aachen, Germany, to make OLED one of the mainstream lighting technologies by the end of 2012. Other large companies including GE, Eastman Kodak, Osram, Sharp, Toshiba, Mitsubishi, NEC, Hitachi, etc. have also invested in OLED lighting product development in recent years.

The reason why OLED lighting technology is quickly picked up is mainly due to the characteristics of OLED, which allows the design of lighting products to add more free space for imagination. It not only presents surface self-luminescence, but also can be made flexible, can be curled, and even can design imaging. Window or mirror-like lamps, but also has the advantages of energy saving, light and thin, no noise and environmental protection. It is expected that OLED lighting will be widely used in various fields such as general or decorative lighting, automotive, medical, industrial, advertising, signage, billboards, etc. In 2012, OLED lighting has been regarded as the first year of OLED lighting.

Regardless of the luminous efficiency and lifetime of OLEDs, it is still an issue that OLEDs need to be overcome and further improved in the lighting application market. However, as more and more manufacturers join the OLED lighting technology field, it is generally believed that the progress of OLED lighting technology will also accelerate. However, as the production process of OLED panels (cost considerations), OLED may also have to accelerate the production of high-generation production lines (at least 5th generation line or more), it will help the rapid decline in the cost of OLED lighting components, improve competitiveness, in order to accelerate the popularity .

On the other hand, as with other lighting technology products (such as LED lighting), how OLED lighting supply chain manufacturers plan to use downstream lighting system products in the future, such as innovative flat luminaires (OLED display panel light sources) and in-cell luminaires, And OLED lighting with the most distinctive flexible lighting, or medical and other special lighting, etc., to enhance the added value of the overall OLED lighting, may be one of the key directions for every one of the OLED lighting market players.
