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

该小型企业创新研究（SBIR）第一阶段项目致力于通过溶液工艺实现低成本，高性能多层有机发光器件（OLED）的方法。OLED作为下一代显示和照明技术正在兴起，它们具有许多优于液晶显示器的内在优势，包括更明亮和更清晰的显示，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、颜色质量优异、设计新颖以及显着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溶液的非真空制造工艺将导致低制造成本。然而，目前溶液处理的OLED的效率对于照明应用来说仍然太低。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，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的显示器正在侵占目前液晶主导的平板显示器市场，该市场在2007年价值数百亿美元，具有前所未有的属性，例如柔性和透明度，这是其他显示技术无法实现的。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荧光灯管更高的照明效率，从而显著节省能源和环境。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征。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，并带来令人印象深刻的环境节约。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被创造沿着许多新的高质量的工作。

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.
