The developement of a high information capacity Chinese character generaor, i.e. Chinese character tube is described briefly. It is a high capacity, electron beam addressed, read only memory. Information capacity of one tube is more than one megabit. This kind of Chinese character generator has the advantage of small size, high information capacity, low cost and wide application. It can be applied to various Chinese character information processing systems.The working principle is described briefly. The experimental results of typeⅠtube (on tube can store 512 Chinese characters with 4848 dot matrix per each Chinese characteer) are given. Finally the prospect for application and development of this kind of Chinese character tube is preliminarily estimated.
