Penetrating type television screen and its manufacture

Abstract

Abstract PURPOSE: To obtain a screen of high brightness and excellent efficiency of diffusion suitable to a penetrating type large television set, by forming a light-diffusing layer, light-absorbing layer, etc., on a transparent screen member while their forming materials are made in an ink state. CONSTITUTION: On transparent screen member 1 of about 0.5W5mm in thickness made of vinyl-chloride resin, acrylic resin, polycarbonate resin, or the like, light- diffusion layer 2 is formed of organic resin that contains corpuscular pigment such as powdery glass, titanium oxide and corpuscular silica. Next, light-absorbing layer is formed on light-diffusing layer 2 by use of organic resin that contains various inorganic or organic coloring pigment and dye. To protect light-diffusing layer 2 and light-absorbing layer 3, surface protective layer 4 is formed of resin of superior hardness such as acrylic resin. In formation of each layer, forming material is made in an ink state and printing or coating is applied, obtaining the titled screen. COPYRIGHT: (C)1981,JPO&Japio
