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

这个小型企业技术转让（STTR）二期项目将展示一种全彩色、低成本、低功耗显示的堆叠有机发光器件（SOLED）技术。通用显示公司（UDC）和普林斯顿大学正在开发这种新颖的SOLED架构，其中红色(R)，绿色(G)和蓝色(B)子像素垂直定位，以发出任何颜色和亮度的混合，作为现有并行方法的高效，高性能替代方案。OLED技术基于真空沉积的小分子有机薄膜，具有高亮度和对比度、快速响应时间、低工作电压下的高功率效率和优异的可靠性等优点。第一阶段通过优化器件层来减少微腔效应，展示了饱和的“真彩色”。在第二阶段的目标是：(1)提高SOLED显示级性能，(2)开发商业上可行的工艺，(3)展示全彩色无源矩阵寻址SOLED显示器。如果成功，该项目将为这种创新的低成本显示技术的全面商业化奠定基础。这项技术有潜力服务于无数的消费电子产品（例如，个人数字助理，移动通信和其他手持便携式设备），运输，工业和计算显示应用，这些应用需要低成本，低功耗，全彩性能。

This Small Business Technology Transfer (STTR) Phase II project will demonstrate stacked organic light emitting device (SOLED) technology in a full color, low-cost, low-power display. Universal Display Corporation (UDC) and Princeton University are developing this novel SOLED architecture, where red (R), green (G), and blue (B) sub-pixels are vertically positioned to emit any mixture of color and brightness, as an efficient, high-performance alternative to the existing side-by-side approaches. Based on vacuum-deposited, small-molecule organic thin films, OLED technology is widely recognized for high brightness and contrast, fast response time, high power efficiency at low operating voltage, and excellent reliability. Phase I demonstrated saturated, 'true-color' by optimizing the device layers to reduce microcavity effects. In Phase II the goals are: (1) improve SOLED display-level performance, (2) develop commercially-viable processes, and (3) demonstrate a full-color, passive matrix addressed SOLED display. If successful, this program will provide the basis for full-scale commercialization of this innovative low-cost display technology. This technology has the potential to serve a myriad of consumer electronics (e.g., personal digital assistants, mobile communicators and other handheld portable devices), transportation, industrial and computing display applications, where low-cost, low-power, full-color performance is desired.
