SBIR Phase I: Low Cost TFEL Head Mounted Displays

9560589 Halverson这个小型企业创新研究第一阶段项目将研究微型薄膜电致发光(TFEL)显示器的低成本制造工艺。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设备。无源矩阵寻址有望通过减少显示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，预计生产能力将进一步提高。通过高分辨率掩模离子注入多色激活剂将被用来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信息传输的应用，如设备维护、远程呈现手术和用于培训的模拟器。最大的潜在商业用途将是高性能的虚拟现实娱乐系统。

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.
