In one aspect, the invention encompasses a method of fabricating a display screen. Phosphor molecules are electrophoretically deposited onto a substrate in a first solution having a first hydroxide ion concentration. The deposited phosphor molecules are then rinsed with a second solution having an hydroxide ion concentration greater than the first hydroxide ion concentration. In another aspect, the invention encompasses a method of depositing phosphor molecules over selected regions of a substrate. Conductive regions are formed over portions of a substrate while non-conductive regions are left over other portions of the substrate. Phosphor molecules are electrophoretically deposited onto the conductive regions of the substrate in a first solution having a first hydroxide ion concentration. The substrate is then rinsed with a second solution having a second hydroxide ion concentration greater than the first hydroxide ion concentration. After the rinsing, the deposited phosphor molecules are dried.
