SBIR Phase I:Fabrication of Luminescent Phosphor Plasma-sphere Arrays for Display Applications

这个小企业创新研究第一阶段研究项目将研究生产密封空心气体封装球体（等离子体球体）的可行性，其外壳由经过改进的加工方法加工的荧光粉组合物制成。等离子体球的一个应用是在显示器中使用的像素元件。等离子体球被放置在柔性电可寻址阵列上。当在等离子体球上施加电压时，封装的气体电离并发光。由发光气体产生的紫外线辐射将从内部激发磷光体外壳。荧光粉外壳将紫外线转换为可见光。该SBIR的成功完成将推动公司目前的单色显示技术向全彩色发展。目前的等离子体外壳是电介质和密封剂。所提出的等离子体球壳将是一个电介质，一个密封剂和一个发光体。等离子体球阵列是用一个独特的低成本工艺生产的。这一过程最终将允许以刚性玻璃显示器的一小部分成本生产地毯大小的显示器。卷对卷的生产方法允许灵活的制造和对不断变化的消费者需求的响应。一个单一的宽幅可以切割成各种尺寸和纵横比。整个等离子体球阵列的生产过程是环境友好的。它使用最少的材料，并消除有害材料，包括铅，这是常用的电子制造。其他优点包括更长的寿命，更小的外形尺寸和更大比例的可生物降解材料。

This Small Business Innovation Research Phase I research project will investigate feasibility of producing hermetic hollow gas encapsulating spheres (Plasma-spheres) with shells fabricated from phosphor compositions processed with modified processing methods. One application of Plasma-spheres is pixel elements used in displays. Plasma-spheres are placed on flexible electrically addressable arrays. When a voltage is applied across the Plasma-sphere the encapsulated gas ionizes and glows. UV radiation produced by the glowing gas will excite the phosphor shell form the inside. The phosphor shell will convert UV to visible light. The successful completion of this SBIR will result in advancing the company's current monochrome display technology to full color. The current Plasmasphere shell is dielectric and an encapsulant. The proposed Plasma-sphere shell will be a dielectric, an encapsulant and a lumiphor.Plasma-sphere arrays are produced with a unique low cost process. This process will eventually allow carpet size displays to be produced at a fraction of the cost of rigid glass displays. The roll-to-roll production method allows flexible manufacturing and responsiveness to changing consumer demands. A single wide-web can be cut to a variety of sizes and aspect ratios. The entire Plasma-sphere array production process is environmentally benign. It uses a minimum of materials, and eliminates harmful materials including lead, which is commonly used in the manufacture of electronics. Other advantages include longer life, smaller form factor, and a greater percentage of biodegradable materials.
