9560589 Halverson This Small Business Innovation Research (SBIR) Phase I project will investigate a low-cost manufacturing process for miniature thin film electroluminescent (TFEL) displays. A TFEL head mounted display (HMD) will be based on passive matrix addressing and indium bump bonded drive electronics. Passive matrix addressing is expected to simplify fabrication and improve HMD manufacturing by decreasing the number of high voltage drive transistors required for display operation. Additional improvements in producibility are expected due to separate fabrication and test of the miniature TFEL panel and drive chips. Ion implantation of multicolor activators through high resolution masks will be used to introduce luminescent centers selectively and form color pixels. Miniaturization of the TFEL panel would allow high refresh rates and, therefore, a high-brightness display. Low cost, miniaturized TFEL displays will be used in applications requiring hands-free transfer of information such as equipment maintenance, telepresence surgery, and simulators for training. The largest potential commercial use will be high-performance virtual reality entertainment systems.

小行星9560589 这个小企业创新研究（SBIR）第一阶段项目将研究一种低成本的微型薄膜电致发光（TFEL）显示器的制造工艺。 TFEL头戴式显示器（HMD）将基于无源矩阵寻址和铟凸点键合驱动电子器件。 预期无源矩阵寻址通过减少显示器操作所需的高压驱动晶体管的数量来简化制造并改进HMD制造。 由于微型TFEL面板和驱动芯片的单独制造和测试，预计生产率将进一步提高。 通过高分辨率掩模离子注入荧光激活剂将用于选择性地引入发光中心并形成彩色像素。 TFEL面板的小型化将允许高刷新率，并且因此允许高亮度显示器。 低成本、小型化的TFEL显示器将用于需要免提传输信息的应用，如设备维护、远程呈现手术和培训模拟器。 最大的潜在商业用途将是高性能虚拟现实娱乐系统。
