Method of developing a latent charge image |
摘要 |
A method for developing an electrostatic latent charge image formed on a photoreceptor 36 which is disposed on an interior surface of a faceplate panel 12 of a CRT 10 utilizes a developer 40 having a developing chamber 42 with a sidewall 50 closed by a bottom end 44 and a panel support 46 at the other end. An opening 48 is formed through the panel support 46 to provide access to and support for the faceplate panel 12. A panel grid 74 is disposed in proximity to said interior surface of said faceplate panel 12 and operated at a first potential to control the electric field from the latent charge image. A tank grid 56 is disposed within said developer 40 and spaced from the sidewall 50, the bottom 44 and the panel grid 74. A triboelectric gun 84 is disposed within the developer 40 for imparting a desired charge polarity to the screen structure material and for distributing the charged screen structure material onto the latent charge image. An electrometer 66 and a phosphor deposition monitor 90 monitor the deposition of the charged screen structure material onto the latent charge image; and a controller 68 terminates the deposition of the charged screen structure material when sufficient material is deposited. The Tank grid 56 is operated at a potential different from the potential on the panel grid 74 so that the tank grid 56 controls the electrostatic forces within the developer 40.
