Abstract
An apparatus for forming phosphor layers on a display panel includes a base plate on which a display panel is placed. The base plate is inclined at an adjustable angle. The display panel, having a panel plate and barrier ribs formed on the panel plate is placed on the base plate. A spray unit includes a nozzle assembly for spraying a slurry containing phosphors into spaces between the barrier ribs. A charged unit for exerting electrostatic force on the phosphors is positioned adjacent to the display panel. The apparatus enables rapid formation of uniform phosphor layers on a display panel with the phosphor particles located adjacent to the surfaces of the phosphor layers.
