Abstract
A method of electrophotographically manufacturing a luminescent line screen 22 within a viewing area of a faceplate panel 12 includes providing a matrix 23 having a border 123 extending beyond the viewing area. A photoreceptor 36 overlies the matrix. The photoreceptor is electrostatically charged and a color selection electrode 25, having a multiplicity of openings therethrough, is mounted therein. The panel 12 is positioned on an exposure device having a multi-position visible light source. A least one series of light exposures utilizes both first and second order illumination to form selectively discharge the photoreceptor 36 in the viewing area and on the border 123 of the matrix. Then, triboelectrically charged, color-emitting phosphor is deposited onto the illuminated areas of the photoreceptor to form phosphor lines in the viewing area and phosphor traps over the matrix border.
