STTR Phase I: Improved Addressing Speed of Plasma-sphere Arrays

这个小型企业技术转移第一阶段的研究项目将研究提高等离子球寻址速度的可行性。等离子体球体是中空的透明外壳，封装了选定的加压气体。当在壳体上施加电压时，气体电离并发光。等离子球应用于柔性的、电可寻址的阵列，形成等离子球阵列，用于大面积等离子显示。等离子球阵列和标准等离子显示器一样，需要二次电子发射材料来提高寻址速度。包括氧化钡、氧化钙、氧化锶和锶掺杂LaMnO3 （LSM）在内的几种有前途的薄材料和厚材料将被研究。该工艺为制作视频速度的大面积等离子显示器提供了一种新的方法。等离子球阵列与其他显示技术的不同之处在于，它允许低成本、灵活、超大、全彩色和全动态视频的显示。等离子球阵列是显示技术的一大突破。它摆脱了亚洲许多显示器制造商所采用的传统半导体制造工艺，代之以美国公司所采用和理解的低成本塑料、玻璃和印刷工艺。高速寻址的成功开发将有助于该产品在庞大且不断增长的动态标牌市场中走向商业化。与超大型LED显示屏相比，等离子球阵列的生产成本要低一个数量级。等离子球阵列可以做得像LED显示屏一样大，同时保留传统刚性等离子显示器的许多特殊功能，包括良好的视角、高亮度、出色的对比度和全动态视频。

This Small Business Technology Transfer Phase I research project will investigate the feasibility of improving the addressing speed of Plasma-sphere. Plasma-spheres are hollow transparent shells that encapsulate a selected pressurized gas. When a voltage is applied across the shell, the gas ionizes and glows. Plasma-spheres are applied to flexible, electrically addressable arrays to form Plasma-sphere arrays for use as large area plasma displays. Plasma-sphere arrays, like standard plasma displays require secondary electron emitting materials to increases addressing speeds. Several promising materials, both thin and thick, will be investigated including Barium Oxide, Calcium Oxide, Strontium Oxide and strontium-doped LaMnO3 (LSM). This process presents a novel approach to produce video speed large area plasma displays. The Plasma-sphere array differs from other display technologies in that it allows for low-cost displays that are flexible, ultra-large, with full-color and full-motion video. The Plasma-sphere array is a breakthrough in display technology. It moves away from the traditional semiconductor fabrication processes as practiced by many display manufacturers in Asia and replaces them with low cost plastic, glass, and printing processes practiced and well understood by US based companies. The successful development of high speed addressing will help move this product toward commercialization in the large and growing market of dynamic signage. Plasma-sphere arrays are an order of magnitude lower in production cost when compared with ultra large LED displays. The Plasma-sphere array can be made large like an LED display, while retaining many of the exceptional features of a conventional, rigid plasma display including good viewing angle, high brightness, excellent contrast, and full motion video.
