  • Method of electrophotographically manufacturing a display screen for a color display tube
    Patent number: 4448866
    Abstract: In an electrophotographic process for producing a display screen on the window of a color display tube, a step is performed which increases the potential difference between areas of the screen which have been charged to attract charged particles of a screening material and areas of the screen not charged to attract such particles. This increased potential difference increases the attraction force, thereby improving particle retention until the screening material is permanently attached.
