Small Firms Collaborative R&D Project with Rainbow Displays, Endicott, NY

9815599 Kroger该项目是在美国国家科学基金会成立的S/IUCRC综合电子工程中心的领导下，作为美国国家科学基金会研究中心-小公司合作研发计划的一部分进行的，该项目是宾厄姆顿大学和彩虹显示器公司之间的合作研究和开发计划。（RDI）。 后者是位于纽约州恩迪科特的一家小型初创企业，其目标是以具有竞争力的成本生产大屏幕有源矩阵液晶显示器（LCD），通过平铺四个小型LCD来生产单个、大面积、无缝（对人眼）显示器。 该项目将解决与液晶显示技术相关的两个不同的问题，如前所述，由RDI使用原型硬件。 第一个问题与承载驱动器设备（其驱动屏幕上的像素）的柔性电路与玻璃显示屏上的氧化铟锡（ITO）金属化之间的互连的可靠性有关。 大学研究人员和RDI粘合工程师将共同开发一种可靠的最佳粘合工艺。第二个问题涉及将瓷砖组装成复合层压材料。 平铺的LCD几乎对接在一起，并且可能具有略微不同的厚度。 本发明的组装方法使用液体粘合剂来吸收高度上的任何差异并填充面板之间的空腔。 RDI将把LCD面板对接在一起，并在LCD和保护玻璃盖板之间使用聚合物薄膜型粘合剂。 这将提供改进的分辨率，最小化面板对准要求并降低组装成本。 本研究将使用现有的代码对所提出的结构进行建模，并评估薄膜材料特性、薄膜厚度和LCD面板厚度与组件参数（辊速、压力、曲率、宽度等）之间的相互作用。

9815599KrogerThis project is carried out as a part of the NSF Research Centers - Small Firms Collaborative R&D initiative, under the leadership of the Integrated Electronics Engineering Center, an S/IUCRC established by the National Science Foundation.This project is a collaborative research and development program between Binghamton University and Rainbow Displays Inc. (RDI). The latter is a small start-up enterprise located in Endicott, NY, whose goal is to produce at a competitive cost, a large screen active matrix liquid crystal display (LCD) by tiling four small LCD's to produce a single, large area, seamless (to the human eye) display. The project will address two different problems associated with liquid crystal display technology as previously demonstrated, with prototype hardware, by RDI. The first is related to the reliability of the interconnection between the flex circuitry which carries the driver device (which actuates the pixels on the screen) and the Indium - Tin Oxide (ITO) metallization on the glass display screen. University researchers and RDI bonding engineers will jointly develop a reliable, optimum bonding process.The second problem involves the assembly of the tiles in a composite lamination. The tiled LCDs are almost butted together and may have slightly different thickness. The present method of assembly uses liquid adhesive to take up any differences in height and to fill the cavity between the panels. RDI will butt the LCD panels together and use a polymer film type adhesive between the LCDs and the protective glass cover plate. This will provide improved resolution, minimize panel alignment requirements and reduce the cost of assembly. This study will use existing codes to model the proposed structure and to evaluate the interaction between the film material properties, film thickness and LCD panel thickness with the assembly parameters; roller speed, pressure, curvature, width etc.
