本文提出了一种三束一字型具有线形荧光粉条的新型无荫罩彩色显像管。它的荧光粉条与行扫描方向平行,三束平面与行扫描方向垂直。利用电视扫描特性,该管的结构不需任何束指引装置,就能使三束电子准确地打在各自对应的粉条上,并使三束电子在换行和换场时准确地选色,保证色纯。 In this paper, a new type of shadowless mask color picture tube with three-in-line linear phosphor strips is proposed. Its phosphor strip is parallel to the line scan direction, and the three beam planes are perpendicular to the line scan direction. The use of television scanning features, the structure of the tube without any beam guidance device, you can make three electron accurately hit the respective vermicelli, and the three-beam electrons in the line and change the field accurately select the color, ensure that the color pure.
