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

这项小型企业技术转移第一阶段研究项目将研究提高等离子球体寻址速度的可行性。等离子体球是中空的透明外壳，封装了选定的加压气体。当在外壳上施加电压时，气体就会电离并发光。等离子体球被应用于柔性的、电可寻址的阵列，以形成用作大面积等离子体显示器的等离子体球阵列。与标准等离子显示器一样，等离子球阵列阵需要二次电子发射材料来提高寻址速度。几种很有前途的材料，无论是薄的还是厚的，都将被研究，包括BaO，CaO，SrO和掺锶的LaMnO_3(LSM)。这一工艺提供了一种生产视频速度大面积等离子体显示器的新方法。等离子球体阵列与其他显示技术的不同之处在于，它允许使用灵活的、超大的、具有全色和全运动视频的低成本显示器。等离子体球阵列是显示技术的一项突破。它摆脱了亚洲许多显示器制造商采用的传统半导体制造工艺，取而代之的是美国公司实践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推动该产品在庞大且不断增长的动态标牌市场走向商业化。与超大尺寸LED显示屏相比，等离子球面阵列的生产成本低了一个数量级。等离子球体阵列可以像LED显示器一样大，同时保留了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.
