A PHOTOCONDUCTIVE LAYER SPREADING SOLUTION FOR MANUFACTURING A DRY-TYPE ELECTROPHOTOGRAPHICAL SCREEN OF CRT, AND A MANUFACTURING METHOD OF THE SAME SCREEN USING THE SAME

摘要

PURPOSE: An optical conductive layer application solution for manufacturing a dry electrophotographical screen of a cathode ray tube and a method for manufacturing a screen using the same are provided to control and maintain easily the amount of electrification by improving an electrification characteristic. CONSTITUTION: A volatile conductive layer(132) is formed on an inner face(18) of a panel. A volatile optical conductive layer(134) including a tetracyanoethylene of 2-5 weight percent is formed on the volatile conductive layer(132). A static charge is electrified to the volatile optical conductive layer(134). The static charge is emitted from the volatile optical conductive layer(134) by an ultraviolet ray. The volatile optical conductive layer(134) is exposed thereby. Powder particles are adhered to the volatile optical conductive layer, composed of 0.1- 1w% of diphenylpicrylhydrazine(DPPH) and a very small amount of tetracyanoquinodimethane(TCNQ)(134), by the static charge.
