Abstract
PURPOSE: To form a color CRT suitable for graphic display, by using the central area of the fluorescent picture face as a polychromatic display section, and the peripheral areas of the picture face as monochromatic display sections constructed of phosphor picture elements of a single nature.
CONSTITUTION: A fluorescent picture face 3 of a color CRT is constructed of A area which is a polychromatic display section having light emitting phosphor picture elements of three colors, red, green, and blue, B and C areas, each of which is a monochromatic display section, having a single colored green and red light emitting phosphor picture elements respectively. That is, the central area A, where the improvement of convergence and colorimetric purity characteristics can easily be effected, is used as a three color section, and the peripheral areas B and C, where the improvement of the characteristics is difficult, are used as single-phosphor picture-element sections, thus utilizing the central area A as a graphic display section and the peripheral areas as character display sections for explanation sentences or the like, a color CRT suitable for a graphic display can be obtained.
