设计了一种用于视障人士电子阅读的机械式点阵显示系统。该系统通过小棘爪锁定显示针的不同位置以保持触点的状态，采用Z 向驱动器配合XY移动平台顺序控制每个显示针的凸起，而后由复位驱动器统一复位，从而实现系统中多个触点的凸起和平整状态的自动切换。实验结果表明：采用单个Z 向驱动器的系统可在1分钟内完成54个触点的凸起和平整状态自动转换。

This paper proposed a tactile display system of mechanical dot matrix for the blind’s electronic reading.The statuses of dots were kept by claws latching the different positions of the dis-play pins,and the raise status of display pins were controlled by one Z axis actuator cooperating with XY mobile stage.Then all the display pins would be reset by the reset actuator,so that the statuses of dots might be interchanged automatically.The experimental results show that 54 dots can be auto-matically interchanged in 1 minute between upward and downward positions by using a Z axis actua-tor.
