Color light source tube
专利汇可以提供Color light source tube专利检索，专利查询，专利分析的服务。并且PURPOSE:To form color display screens simply and efficiently by coating phosphors on a thin glass plate to form phosphor screens of three prime colors and by sticking it on the internal face of a display screen made of a transparent glass. CONSTITUTION:Phosphors of G, B, R colors are coated on a thin plate of transparent micro sheet glass, etc. by means of a spray process or an electrodeposition process, and it is cut to form a phosphor plate 21, which is then sticked and arranged on the internal face of a display screen 1 made of transparent glass with an adhesive 22 made of potassium silicate, etc. to form a color display screen. Next, electron guns 6 radiating electron beams to individual phosphor screens are arranged facing the screens, and they are vacuum packed within an outer housing cylinder 2, thus a color light source tube used for a large- sized color display unit is formed. Therefore, phosphor screens 8 of G, B, R colors can be formed under an extremely simple process, and the productivity can be improved.，下面是Color light source tube专利的具体信息内容。
