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用于与盲人交流的平板显示器的开发。该技术的主要组成部分是磁性盲文点模块（BDM），由聚合物和磁性材料的专有混合物组成，30 × 60个点，用于多线可更新盲文显示器（rbd）。目前基于压电技术和独立盲文单元的rbd存在许多固有问题：需要维护的部件众多、功耗高、热量积累、排除图形的限制、装配过程困难、价格昂贵、维修成本高。它们也很重、笨重，而且很脆弱。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）的盲文细胞扫描条激活，将消除大多数这些问题，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为业界提供了一个急需的解决方案，以解决由独立盲文单元组成的rbd中存在的许多技术难题。这一创新将提供组件，以提高现有的产品线显著降低成本。它还将为手机上的盲文短信等全新应用提供潜力。

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.
