ABSTRACT:
A method of developing a screen of a cathode ray tube includes the steps of establishing an uniform electrostatic charge on selected areas of an inner surface of a panel with a predetermined pattern, rotating a nozzle to a predetermined angle with respect to the inner surface of a panel, and moving the rotated nozzle backwards and forwards while spraying a dry-powdered and electrically charged screen structure material on the selected areas of the inner surface of the panel.
