SBIR Phase I: Solution Processed p-i-n type Multilayer White Emission OLED with High Power Efficiency and Long Lifetime

小型企业创新研究(SBIR)第一阶段项目致力于通过溶液工艺实现低成本、高性能的多层有机发光器件(OLED)。OLED是一种新兴的新一代显示和照明技术，与液晶显示器相比，OLED具有许多固有的优势，包括更明亮、更清晰的显示、大视角、更简单的结构、低成本和快速响应时间。他们还承诺提供更节能的固态照明光源，具有寿命长、色彩质量优异、设计新颖、显著节省能源和环境的特点。OLED器件结构的简单性和相关的基于解决方案的非真空制造工艺将导致较低的制造成本。然而，目前溶液处理OLED的效率仍然太低，不适合照明应用。PI和他的团队将利用他们在这一领域的专业知识来提高OLED的效率。如果成功，这项拟议技术的商业潜力是双重的：固态照明和平板显示器，包括柔性显示器。基于OLED的显示器正以其他显示技术无法达到的灵活性和透明度等前所未有的特性，侵蚀着目前以液晶为主的平板显示器市场，2007年的市场价值达数百亿美元。对于固态照明(SSL)，从能量转换的角度来看，OLED本质上实现了比传统白炽灯和日光灯更高的照明效率，从而显著节省了能源和环境。基于OLED的照明还提供了长寿命、高色彩质量和当前光源所不具备的新颖设计特性。据估计，到2020年，仅在美国，基于OLED的照明就可累计节省1150亿美元的资金。OLED照明还有望取代传统光源，节省大量环境。SSL也符合美国的国家利益。随着高性能OLED的快速发展和商业化，美国在SSL领域的领导地位将得到保证。一个新的照明行业将伴随着许多新的高质量工作岗位一起被创造出来。

This Small Business Innovation Research (SBIR) Phase I project addresses a method to achieve low-cost, high performance multiple-layer organic light emitting devices (OLEDs) by solution process. OLED is emerging as a next-generation display and lighting technology, they have a number of intrinsic advantages over liquid crystal displays including brighter and clearer displays, large viewing angles, simpler construction, low cost, and fast response times. They also hold a promise to provide more energy-efficient solid state lighting sources featuring long lifetime, excellent color quality, novel designs, and significant energy and environmental savings. The simplicity of OLED device structures and the associated solution based, non-vacuum fabrication processing will lead to low fabrication costs. However, currently the efficiency of solution processed OLEDs is still too low for lighting applications. The PI and his team will use their expertise in this area to enhance the efficiency of OLEDs. If successful the commercial potential of the proposed technology is two-fold: solid state lighting and flat panel displays, including flexible displays. OLED based displays are encroaching on the currently liquid crystal dominated flat panel display market valued at tens of billions of dollars in 2007 with unprecedented attributes such as flexibility and transparency, unattainable from other display technologies. For solid state lighting (SSL), OLED intrinsically achieves higher lighting efficiency than conventional incandescent lamps and fluorescent tubes from the energy conversion standpoint, leading to significant energy and environmental savings. OLED based lighting also offers long lifetime, high color quality, and novel design features not available with current light sources. OLED based lighting is estimated to provide cumulative financial savings of $115 billion in the US alone by 2020. OLED lighting also promises to replace conventional light sources, with impressive environmental savings. SSL also serves US national interests. With rapid development and commercialization of high performance OLEDs, the US leadership in SSL will be assured. A new lighting industry will be created along with many new high quality jobs.
