Ⅰ前言近年来电子计算机、集成电路的迅速发展和应用,对于计算机、雷达与其他整机的显示器提出了新的要求。目前,在显示器件领域内,传统的阴极射线管(示波管、指示管、存储管、显象管等)还占统治地位。这些器件经过长期的改进,具有相当好的电性能,但体积大,电 Ⅰ Preface In recent years, the rapid development and application of electronic computers and integrated circuits have brought new demands on the display of computers, radars and other complete machines. Currently, in the field of display devices, the traditional cathode ray tubes (oscilloscopes, indicator tubes, storage tubes, kinescopes, etc.) also dominate. These devices after long-term improvement, with very good electrical properties, but bulky, electricity
