    摘要： In accordance with the present invention, a method of electro-photographically manufacturing a luminescent screen assembly for a color CRT 10 on an interior surface of a faceplate panel 12 is described. A volatilizable, organic conductive (OC) layer 32 is provided on the interior surface of the panel and a volatilizable, organic photoconductive (OPC) layer 34 overlies the OC layer. The method includes the steps of: establishing a substantially uniform electrostatic charge on the OPC layer; exposing selected areas of the OPC layer to visible light to affect the charge thereon; developing the selected areas of the OPC layer with a triboelectrically charged dry-powdered, screen structure materials; fixing the screen structure materials to the underlying OPC layer with a suitable fixative; filming the screen structure materials; aluminizing the screen; and baking the aluminized screen. The present method is an improvement over prior methods because the relative humidity (RH) during the charging step is maintained above a humidity level below which the performance of the OC layer is negatively impacted by a reduction in its ion transfer mobility which makes it difficult to apply a usable corona charge to the overlying OPC layer, and below a humidity level above which the OC layer swells causing cracking in the OPC layer. Additionally, the RH during the development step is maintained below a humidity above which the screen structure materials can absorb water and macro-agglomerate, thereby changing the charge-to-mass ration of the screen structure materials to a value which adversely affects the deposition thereof.

    摘要： The method of electrophotographically manufacturing a luminescent screen assembly on a substrate of a CRT, according to the present invention, includes the steps of coating the substrate with a conductive layer and overcoating the conductive layer with a photoconductive layer, establishing an electrostatic charge on the photoconductive layer, and exposing selected areas of the photoconductive layer to visible light to affect the charge thereon. Then, the selected areas of the photoconductive layer are developed with triboelectrically charged, dry-powdered, surface-treated screen structure materials. The improved process increases the adherence of the surface-treated materials to the photoconductive layer by contacting the surface-treated materials with a solvent to render the photoconductive layer and the materials tacky. The dried screen is fixed with a plurality of coatings of an aqueous alcohol mixture of dichromated polyvinyl alcohol or potassium silicate and then filmed, aluminized and baked to form the screen assembly.

The present method is an improvement over prior methods because the fixing step utilizes an electrostatic spray to uniformly contact the phosphors and the underlying OPC layer with the fixative, without moving the phosphors.

    摘要： The method of electrophotographically manufacturing a luminescent screen on a substrate of a color CRT, according to the present invention, includes the steps of forming a photoreceptor by sequentially coating the substrate to form a conductive layer and an overcoating of a photoconductive layer, establishing an electrostatic charge on the photoconductive layer, and exposing selected areas of the photoconductive layer to visible light to affect the charge thereon. Then the photoconductive layer is developed by the application of suitable triboelectrically charged, dry-powdered screen structure materials. The improved process provides at least one wear-resistant, conductive contact patch on a peripheral portion of a surface of the substrate. The contact patch has a first portion which underlies at least one of the layers of the photoreceptor and is in electrical contact with the conductive layer, and a second portion which extends from the photoreceptor. The contact patch is utilized during the manufacturing process to electrically ground the conductive layer during charging of the photoconductive layer. The contact patch also is utilized to measure the charge on the photoconductive layer during the developing process. Additionally, the contact patch provides an electrical contact, in the finished tube, between an aluminized layer on the screen and at least one support for a shadow mask.
