Novaled and OSRAM Optoelectronics have produced lighting panels that become transparent when the power is turned off (Figure 13). The problem with this type of transparent panel is that the front and back sides will illuminate if some measures are not taken. This is because, in OLED illumination, a metal electrode such as aluminum or a metal substrate used for a negative electrode is generally used as a reflecting plate, and these members are also required to use a transparent material. If the window glass adopts such transparent illumination, it is not only in the room, but also easy to connect with the outside of the room. It also uses the transparent and flexible features to maximize the transparency and flexibility of the OLED lighting. The cost is lower, and competition with existing lighting methods is not easy. This is because large-scale replacement work, including lighting fixtures and installation appliances, is essential.
Therefore, some manufacturers have placed their power on panel development that can exploit the characteristics of OLED lighting. Namely: transparency and flexibility.

If the window glass is made of such transparent lighting, it is not only in the room, but also easily lit up outside the room. In this respect, "although the details cannot be announced, the technology of achieving one-way illumination at the component level without the use of reflectors, etc. is currently under development" (Karsten Heuser, Director of Optoelectronics OLED Technology, OSRAM).
Seiko Epson at the SID 2008 Symposium released technology that focuses the direction of light in one direction 8). The company's approach is also available as an option.
Does the roll-to-roll type have EL lighting waste heat market take 2 years, or 10 years?
If another feature of OLED lighting is "flexible", the image of the lighting may be greatly improved in terms of shape, thickness, use and cost. At present, GE, Konica Minolta and some European research institutes are actively carrying out research in this area (figure) GE has completed the trial production of 8-inch (about 20cm) wide OLED lighting panels by roll-to-roll. The first supply will begin in 2010.
Although Konica Minolta, which cooperates with GE, did not disclose the division of responsibilities for development, the company has also completed trial production of flexible OLED lighting. “When other companies finally caught up with the conversion efficiency of 64 lm/W that we achieved two years ago, we are one step ahead in coating method†(Konica Minolta’s village), discourse It shows the confidence of the company.
In addition, there are also opinions that doubt the feasibility of this method. According to these views, “it is impossible to come up with flexible products in 2010†(a researcher in Japan who is developing evaporation technology), “It takes at least 10 years to make lighting products like newspapers†(Elsbergen of Philips Research). However, some people believe that "the OLED display, which is difficult to achieve positional alignment compared with lighting products, is also conducting research in this area. (Flexible OLED lighting) is much easier technically than it is" (Europe An OLED lighting technician). In the field of organic thin-film solar cells, which is very similar to OLED lighting, Konark Technologies announced that it began mass production of modules in volume-to-roll format in October 2008.
In roll-to-roll OLED lighting, Fraunhofer IPMS is also scheduled to put production equipment into production in 2008. The device forms a layer on a flexible substrate by evaporation. This method is more feasible from the point of using conventional low molecular materials.
Figure 13 is integrated into a transparent backplane to broaden the use of Osram Optoelectronics in December 2007 to produce transparent OLED lighting (a). The transparency is 55% and the panel area is 90cm2. Seiko Epson prototyped a headlamp (b) that formed many fine OLED components on a glass substrate. The principle is that the Al layer, which is the negative electrode of the OLED, shields and reflects light so that light is emitted only in one direction of the transparent panel (c). It is suitable for small-screen reflective LCD panels and electronic papers, etc., which are used to view the display surface with ambient light. (a) Provided by OSRAM Opto.

HolstCentre prototyped a flexible OLED panel (b) with PEN film as the backplane by means of inkjet technology. A first generation roll-to-roll manufacturing unit that can manufacture a 30 cm wide panel is also in place. In June 2008, Fraunhofer IPMS introduced a manufacturing apparatus (c, d) capable of forming a layer by a vapor deposition method in a roll-to-roll mode. It will begin operation in the fourth quarter of 2008. Supports a base plate that is 30cm wide and 0.2-0.5mm thick. (c) Provided by Fraunhofer IPMS.
