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.
Claims10
A method for forming phosphor layers on a display panel, said method comprising the steps of:
- providing a display panel having a panel plate and barrier ribs formed on the panel plate;
- supplying slurry onto the display panel;
- and
- exerting electrostatic force on the slurry located on the display panel by a charged unit disposed adjacent to the display panel.
A method of making a nozzle for applying slurry to spaces between ribs on a display panel comprising the steps of:
- applying a selectively removable material on a first substrate;
- selectively eliminating portions of the removable material from the first substrate to form grooves to create fluid channels;
- and
- attaching a second substrate to the remaining material, so as to cover the grooves.
