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

这个小企业创新研究一期项目旨在开发一项关键技术——高导电性、透明阳极电极，用于高信息密度、大尺寸、发光聚合物显示器。平板、液晶显示器目前用于便携式显示器，如笔记本电脑、个人数字助理或导航引导系统。lcd有一些缺点和限制（包括有限的视角，有限的对比度和相对较慢的响应速度）。在弱光条件下使用lcd需要背光。聚合物发射显示器已成为下一代显示器的有前途的技术，具有许多新颖的功能。它们的加工优势还允许它们用于在平面、非平面甚至柔性基板上制造大面积、轻重量、发光显示器。由于铟锡氧化物阳极的表面导电性低，该技术目前受到有限尺寸和有限像素数量的限制。高导电性、高效透明阳极的成功开发将使聚合物发光二极管应用于大尺寸、高信息密度的显示器。单像素和模型显示设备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.
