STTR Phase I: Saturated Color Red-Green-Blue Organic Light Emitting Diodes for Low-Cost, Low-Power Displays

第一阶段小企业技术转让项目旨在开发用于低功耗、低成本显示器的有机发光二极管（OLED）技术。 基于真空沉积的小分子有机薄膜的专有OLED技术因其出色的亮度和对比度、快速响应时间、低工作电压下的高功率效率以及出色的可靠性而得到广泛认可。 提议者最近展示了一种新颖的堆叠OLED像素架构（SOLED），其实现了高分辨率、全色性能，其中红色（R）、绿色（G）和蓝色（B）子像素垂直定位以发射颜色和亮度的任何混合。 然而，为了实现充分的商业潜力，仍然需要进行大量的研究来实现饱和的全色。 提案人打算进行某些材料研究和器件结构优化，以证明实现饱和R-G-B光谱发射特性的可行性。 如果成功的话，这项研究将为第二阶段使用光刻图形技术的高分辨率全色显示器提供基础。 这项技术有可能服务于运输、工业、通信、计算和消费电子市场，包括个人数字助理、投影显示器、摄像机中的取景器、视频电话、手持计算机、计算机监视器以及最终墙上的电视监视器的应用。

This Phase I Small Business Technology Transfer project seeks to develop organic light emitting diode (OLED) technology for low-power, low-cost displays. A proprietary OLED technology, based on vacuum-deposited, small-molecule organic thin films, is widely recognized for excellent brightness and contrast, fast response time, high power efficiency at low operating voltage, and excellent reliability. The proposer recently demonstrated a novel stacked OLED pixel architecture (SOLED) that achieves high-resolution, full color performance, where the red (R), green (G) and blue (B) sub-pixels are vertically positioned to emit any mixture of color and brightness. To realize full commercial potential, however, significant research remains to be done to achieve saturated full-color. The proposers intend to perform certain materials research and device structure optimization to demonstrate the feasibility of achieving saturated R-G-B spectral emission characteristics. If successful, this research will provide the basis for high resolution, full-color displays in Phase II using photolithographic patterning techniques. This technology has the potential to serve transportation, industrial, communications, computing and consumer electronics markets, including applications for personal digital assistants, projection displays, viewfinders in camcorders, video phones, hand-held computers, computer monitors, and, ultimately, the TV monitor on the wall.
