Abstract

PURPOSE:To improve a threshold of an intensity that generates a flickering in the tube, by determining a proportion of a luminous intensity at the time of completing one field to that average in one field to be in a specific range. CONSTITUTION:A fluorescent substance is used such that a proportion of a luminous intensity at the time of completing one field to an average luminous intensity in one field is 0.15-0.25. In a color picture tube having a tri-color luminous body, the fluorescent substance is constituted by three luminous kinds of red color, green color and blue color. In the fluorescent substance of red and green color light emissions, a proportion of the luminous intensity at the time of completing one field to that average in one field may be determined to be 0.15-0.25.
