Abstract:
1. A method for manufacturing a display device comprising: depositing a conductor on an anode plate; aligning a mask with apertures on the anode plate such that apertures are predetermined locations over selected regions on the anode plate and such that the mask is positioned a distance from the anode plate and does not contact the anode plate and contents on the anode plate, the mask being an electrostatic mask for holding a bias voltage; setting electric field lines between the mask and the anode plate by applying one voltage to the conductor and applying the bias voltage on the mask such that the electric field lines include direct field lines between bottom surfaces of the mask to the conductor; and forming phosphor elements on the selected regions by injecting a flux of charged phosphor particles toward the mask and through the apertures, the charge of the charged phosphor particles being selected such that the charged phosphor particles are forced by the electric field lines to deposit on the selected regions.
