SBIR Phase I: Braille Display Module (BDM)

这个小企业创新研究第一阶段项目调查了一种平板显示器的开发，用于与盲人交流。这项技术的主要组成部分是一个由聚合物和磁性材料的专利混合物组成的磁性盲文点模块（BDM），30 × 60点，用于多行可刷新盲文显示器（RBD）。目前的RBD基于压电技术和单独的盲文单元，具有许多固有的问题：需要维护的部件众多，功耗高，热量积聚，排除图形的限制，组装过程困难，昂贵且昂贵的维修。它们也很重，体积庞大，而且相当脆弱。这些因素严重限制了可以制造的显示区域。磁性BDM的发展，与大规模集成（LSI）的盲文单元与扫描条激活，将消除这些问题的大部分，并大大降低成本。磁性BDM技术将彻底改变盲文显示行业。具有多行和多列显示区域的BDM为行业提供了急需的解决方案，以解决由单独的盲文单元组成的RBD中存在的许多技术难题。这项创新将提供组件，以提高目前的产品线，大大降低成本。它还将为全新的应用提供潜力，如手机上的盲文短信。

This Small Business Innovation Research Phase I project investigates the development of a type of flat panel display for communication with the blind. The main component of this technology is a magnetic Braille Dot Module (BDM) composed of a proprietary blend of polymers and magnetic materials, 30 by 60 dots, for multi-line Refreshable Braille Displays (RBDs). Current RBDs, based on piezoelectric technology and separate Braille cells, have many inherent problems: numerous parts to maintain, high power consumption, heat build up, constraints that preclude graphics, difficult assembly process, expensive, and costly repair. They are also heavy, bulky, and quite fragile. These factors severely limit the display area that can be manufactured. Development of a magnetic BDM, with large-scale integration (LSI) of braille cells with sweep bar activation, will eliminate the majority of these problems and reduce costs dramatically. Magnetic BDM technology will revolutionize the Braille display industry. BDMs with multi-line and multi-column display areas offer the industry a much needed solution to the many technical difficulties found in RBDs composed of separate Braille cells. This innovation will provide components to enhance current product lines with dramatic cost reductions. It will also offer the potential for entirely new applications such as Braille text messages on cell phones.
