This Small Business Innovation Research (SBIR) Phase II project will develop a new type of process to improve the quality and reduce the cost of large liquid crystal displays (LCDs), particularly those used for energy efficient high-definition televisions. Rather than the existing approaches that synthesize a polymer inside the display, this research examines polymers synthesized and purified outside of the display. Side-group liquid crystal polymers (SGLCPs) will be developed that can be used at low concentration as dopants in the liquid crystal mixture that is the active medium in the LCD. Chemical variations on the successful SGLCPs discovered in Phase I will establish molecular-level understanding of the mechanism of the beneficial effects of the dopant. Effects of the dopants on processing behavior (e.g., the process of filling the flat panel) and ultimate performance will be characterized; the results will guide industrial implementation of the dopants.The broader impact/commercial potential of this project on new polymer dopants include improved performance of LCD-TVs, especially in the rapidly growing HDTV segment. Liquid crystal displays are widely used in televisions due to their low operating voltage, low power consumption and thin form factor. Polymer additives will be developed that increase the switching speed, enhance the brightness, improve the viewing angle and maintain the excellent dark state and high contrast that are the hallmarks of vertically-aligned nematic liquid crystal displays (VAN-LCDs). The potential revenues of these compounds could reach $100 million annually within a few years. Scientifically, polymer dopants in LCs represent an entirely new field of science and technology. Finally, this collaborative research will involve a combination of microsynthesis, polymer and LC physical properties and LC display fabrication that will confer upon its principals a comprehensive perspective on the transition of discoveries into competitive product offerings.

这项小型企业创新研究（SBIR）II期项目将开发一种新型的过程，以提高质量并降低大型液晶显示器（LCD）的成本，尤其是用于节能高清电视的过程。 本研究不是在显示屏内合成聚合物的现有方法，而是研究了在显示屏外合成和纯化的聚合物。将开发侧组液晶聚合物（SGLCP），可在低浓度下用作液晶混合物中的掺杂剂，该液态晶体混合物是LCD中的活性培养基。在第一阶段发现的成功SGLCP的化学变化将建立分子级别对掺杂剂有益作用机理的理解。掺杂剂对加工行为的影响（例如，填充平面面板的过程）和最终性能的影响；结果将指导掺杂剂的工业实施。该项目对新聚合物掺杂剂的更广泛的影响/商业潜力包括改善LCD-TVS的性能，尤其是在快速增长的HDTV细分中。 液晶显示器由于其低工作电压，低功耗和薄外形而广泛用于电视中。 将开发聚合物添加剂，以提高开关速度，提高亮度，提高视角并保持出色的深色状态和高对比度，这是垂直平整的列液晶显示器（VAN-LCDS）的标志。 这些化合物的潜在收入可能在几年内每年达到1亿美元。 从科学上讲，LCS中的聚合物掺杂剂代表了一个全新的科学技术领域。 最后，这项合作研究将涉及微型合成，聚合物和LC物理特性以及LC展示制造的结合，它将授予其原理对发现向竞争产品的过渡到竞争产品的全面观点。
