以辉光放电管为像素的电子黑板研究与实现

摘要

In order to develop a simple, low cost electronic blackboard, a method taking the glow discharge tube as the picture element of the electronic blackboard and using electric or magnetic field to write and erase is adopted, and an experiment that controls the glow discharge tube working at certain voltages by using high-voltage electrostatic field or magnetic field and enables it to transform between the "brightly-extinguish" bistable states was done.The experimental results show that the glow discharge tube and the control method can be applied to electronic blackboard.Thus a kind of electronic blackboard which takes the glow discharge tube as the picture element was developed.The electronic blackboard has a simple structure, low cost and good performance.%为了开发一种结构简单、造价低廉的电子黑板,采用了以辉光放电管作为电子黑板像素并以电场或磁场控制书写和擦除的方法;做了利用高压静电场或磁场对一定电压下的辉光放电管进行控制,使其在"亮一灭"双稳态之间转化的实验,实验表明,辉光放电管及其控制方式可应用于电子黑板.由此开发了一种以辉光放电管为像素点阵的新型电子黑板,该电子黑板具有结构简单、成本低廉、显示效果好的特点.
