摘要：
Each beam of a multi-electron beam display device is controlled to achieve uniformity of the displayed image. A collector senses the electron current of each beam. The level of the electron current of each beam is stored in a memory. When a particular beam is to be modulated, the memory is addressed so that the electron current level information for that beam is read out. The stored information and the incoming image element brightness information are combined to modulate the particular electron beam.
