past the high voltage electrode 5 the air and phosphor particles are then highly charged and ionized and shot out of the spray nozzles 7 at a high velocity ie 170 feet per minute the charged particles and air stream strike the side walls and bottom of the spray chamber slow down and spread out moving to fill the chamber and the area under the panel 4 in an ionized cloud the pneumatic air flow pattern cause the particles to strike the side walls and be deflected upwardly into the internal corner radii of the panel at the areas 11 while the electrostatic fields between the metal plate 2 and the panel 4 move the phosphor particles to the grounded inner surface having the wetted photoresist to be stuck thereon during this electrostatic deposition the ionized phosphor particles are both being repelled by the metal plate 2 and attracted to the grounded panel 4 as this occurs the spray gun or the spray nozzle is rotated in one direction this rotation is for at least 360 u00b0 and beyond to form a continuous cloud of charged particles being attracted or pneumatically pushed to the panel 4 in one process the rotation is continuous and the particles are sprayed into the chamber until about 30 u00b0 to about 90 u00b0 from a stop position depending on the type of phosphor particles and photoresist being used at that point the phosphor particles.
