Abstract

PURPOSE:To triplicate the number of picture elements, and increase the accuracy of a cathode-ray tube for a display light source by providing the cathode-ray tube with the same number as the number of plural multicolor phosphor dots of electron guns in positions corresponding to said plural multicolor phosphor dots. CONSTITUTION:A black-light absorbing film 15 made of a graphite matter or the like is applied to the surface of one end of a cathode-ray tube except three differently-colored phosphor dots 11R, 11G and 11B. Three electron guns 13R, 13G and 13B are positioned at the other end of a cathode-ray tube 10 correspondingly to the three phosphor dots 11R, 11G and 11B. A non-focusing flood electron beam 14R is discharged from an electron gun 13R, and irradiates and stimulates the above red-color emitting phosphor dot 11R so as to produce a red light spot 16R. In the same manner as above, the electron gun 13G and 13B discharge non- focusing flood electron beams 14G and 14B, which irradiate and stimulate a green-color emitting and a blue-color emitting phosphor dot 11G and 11B so as to produce a green and a blue light spot 16G and 16B, respectively.

In addition, in the case of such a light bulb method, the fineness ta of each m element is
In order to adjust the current, the applied current to the filament must be turned on and off by 1k, or the applied current must be varied.The wave number response of CRT light bulbs is extremely low at less than 10Hz, and the difference between the applied current and the emission intensity There is a problem that the light emission is not direct and the light emission itself becomes gray due to the applied wIt current, and it is difficult to use it for color display that synthesizes colored light for junior high school 1st punctuation or arbitrary color light. Ta. In addition, the light bulbs used in this kind of white paper manufacturing are generally 10W or more.
