OLED faces multiple challenges

Organic EL (OLED) as the thin and bendable “ultimate source” and was expected to have a rapid development, but recently faces multiple challenges. For many problems lie in the cost and performance, many materials and electromechanical manufacturers have frozen the development of OLED.
In 2011, Panasonic and Idemitsu Kosan Co., Ltd had jointly established an organic EL lighting panel manufacturing and sales company – Panasonic Idemitsu OLED Lighting Co., Ltd. (Hereinafter referred to as PIOL), but on March 31th, 2014, the company stopped operating quietly, due to market size could not expand as expected, the company was closed since was founded three years ago.
PIOL combined the Idemitsu Kosan organic materials and Panasonic Electrical control technology together to manufacture organic EL lighting panel, it had also planned to expand overseas sales. However, after knew there are medical and other special demand, but there are still technical problems exist in the popularity of general lighting field, so even the two companies are considering organic EL lighting will continue to develop in the future, but decided to shrink the front by now.
Organic EL light source uses organic materials that can emit light when applied voltage, features are easy to expand the illumination area, light weight and low power consumption. If the substrate is made of resin instead of conventional glass, the surface can be curved shape. In addition to lighting purposes, it also can be used for television monitors; these two applications are highly anticipated.
Compared to the Panasonic which intends to dissolve the OLED lighting panel subsidiary manufacturing, however, Pioneer, Mitsubishi, Konica Minolta and other Japanese manufacturers are speeding up the OLED production pace.
Pioneer and Mitsubishi Chemical issued a joint press on March 19th that the use of “light-emitting layer coating type” OLED lighting panel has begun volume production and shipment in March; compare to the current “vacuum deposition style” technology, the new type OLED lighting panel can reduce 1/5-1/10 cost, and life can be increased four-times (30,000 hours, the brightness 2,000 cd / m2).
Konica Minolta also announced on March 18th that it will build a new plant in its Kofu factory, to mass produce the world’s first resin substrate of flexible OLED lighting panel (white and dimmable items available); the new plants will be completed in the summer of 2014, and plans to produce about 1 million pcs monthly in the autumn.
