Abstract

PURPOSE:To make sharp the screen, by inverting the red color residual image in rejecting the red color residual image for Braun tube or the like, picturing out the color corresponding to this part, and obtaining white color with the principle of three colors. CONSTITUTION:When electrons are emitted on red color particles of Braun tubes or the like to produce illumination, the residual image may cause tailing phenomenon for unsightly screen. Thus, if the red color residual image is taken place, the red color light is inverted and the residual image part only is compared and picked up. This is pictured after adding equal amount of green, blue and purple colors, this operation is repeated to give the feeling of sight to eyes as if the residual image were disappeared.
