<p>The method develops a uniform density of the screen structure material on a faceplate (18) for a CRT. According to the present invention the method comprises the steps of first-coating the faceplate with a volatilizable conductive layer (132), second-coating the conductive layer with the first photoconductive layer (134) including a dye sensitive to ultraviolet rays, third-coating the ultraviolet-photoconductive layer (134) with a second photoconductive layer (136) including a dye sensitive to visible light. Then, charging the whole area of the second photoconductive layer (136) by exposing the whole surface of the second photoconductive layer (136) to visible light while applying a suitable DC voltage between the conductive layer (132) and the second photoconductive layer (136), and exposing selected areas of said first photoconductive layer to ultraviolet rays through a shadow mask (16) to discharge the charge from the selected areas of the first photoconductive layer (134). Then, in a developing step light-absorptive material particles are sprayed toward layer (136) and fixed with a vapour swelling method.</p> |
