SDK to Produce Large Area Organic EL Panels, Using Innovative Phosphorescent Polymer Technology.
While fluorescent organic EL devices are already available on the market for mobile phone display applications, phosphorescent organic EL devices, which are yet to be commercialized, can theoretically produce four times higher emissive efficiency, resulting in about one-fourth electricity consumption. SDK has achieved a breakthrough by developing a new copolymer - in which phosphorescent substance and other materials are mixed - realizing highest-level emissive efficiency in the industry today.
Although low-molecular-weight-compound-based organic EL devices need to be produced at under vacuum, polymer-based organic EL devices can be produced under less expensive, normal conditions. So far, problems with emissive efficiency and durability hampered commercialization efforts. With SDK's proprietary singlelayer organic electroluminescent devices based on phosphorescent polymer materials and cleaning/interface control technology, however, it is now possible to produce high-performance and stable organic EL panels. (Since an organic EL layer of less than 100 nm in thickness is sandwiched between electrodes, the cleanliness of electrode surface and work function largely influence the device performance.) SDK will further improve the technology and aim to place the new product on the market by the end of 2008.
While organic EL devices are generally developed for high-precision display applications, including mobile phones and large-screen TVs, SDK is aiming to develop advertisement and display applications, fully utilizing the advantages of high emissive efficiency, long durability and large area-emission due to the proprietary phosphorescent copolymer. SDK is planning to achieve annual sales of 10 billion Yen from this product in 2010.
Under the Passion Project, SDK is developing new product lines that will ensure future growth in addition to the established growth driver businesses (hard disk media and semiconductor-processing materials) and new growth drivers (ultra bright LEDs and carbon nanofibers). To accelerate development, SDK will focus its resources on the six selected market areas, or strategic market units (SMUs), including displays and illumination modules.
