SBIR Phase I: High Information Density Displays Made with Semiconductor Polymers

这个小型企业创新研究第一阶段项目旨在开发一项关键技术--用于高信息密度、大尺寸、发光聚合物显示器的高电导率、透明阳极电极。平板液晶显示器目前用于便携式显示器，例如膝上型计算机、个人数字助理或导航导航系统。LCD有几个缺点和局限性(包括视角有限、对比度有限和响应速度相对较慢)。在弱光条件下使用LCD需要背光。聚合物发光显示器具有许多新颖的特点，已成为下一代显示器的一项有前途的技术。它们的工艺优势还允许它们用于在平板、非平板甚至柔性基板上制造大面积、重量轻、发光的显示器。这项技术目前仅限于有限的尺寸和有限的像素数量，因为铟锡氧化物阳极的低表面导电性。成功开发出高导电性、高效率的透明阳极将使聚合物发光二极管用于大尺寸、高信息密度的显示器。单像素和模型显示器件也将在第一阶段制造和表征，大面积(3‘-4’)，高信息密度(1/4 VGA或更高)，图形显示将在第二阶段根据市场反馈的需求开发。

This Small Business Innovation Research Phase I project is aimed at developing a key technology-high conductivity, transparent anode electrode for high information density, large size, emissive polymer displays. Flat-panel, liquid crystal displays are currently used for portable displays such as laptop computers, Personal Digital Assistants or Navigation Guiding Systems. There are several drawbacks and limitations with LCDs (including limited view angle, limited contrast and relatively slow response speed). Backlight is needed for LCDs to be used under weak light conditions. Polymer emissive displays have emerged as promising technology for next generation displays with many novel features. Their processing advantages also allow them to be used for fabricating large area, light weight, emissive displays on flat, non-flat, or even flexible substrates. This technology is currently limited for finite size and the limited number of pixels due to low surface conductivity of Indium Tin Oxide anode.Success in developing a high conductivity, high effective transparency anode will allow the polymer Light Emitting Diodes to be used for large size, high information density displays. Single pixel and model display devices will also be fabricated and characterized during Phase I. Large area (3'-4'), high information density (1/4 VGA or higher), graphic displays will be developed in the Phase II based on the demands from market feedback.
