    • An improved color picture tube, operable in a multistandard television receiver, includes a viewing screen, a shadow mask and an electron gun for generating and projecting three electron beams through the shadow mask and onto the screen. The screen includes phosphor lines that extend in a first direction. The electron beams are subject to deflection in the first direction and in a second direction, that is substantially perpendicular to both the first direction and the phosphor lines. The shadow mask includes elongated slit-shaped apertures that are aligned in columns that substantially parallel the phosphor lines. The adjacent apertures in each column are separated from each other by tie-bars in the mask, and the tie-bars in one column are offset from the tie-bars in adjacent columns in the first direction. The improvement includes the tie-bars in alternate columns lying on substantially straight lines that form an angle of approximately 2 degrees with respect to the second direction.
    • 可在多标准电视接收机中操作的改进的彩色显像管包括观看屏幕,荫罩和电子枪,用于通过荫罩产生和投影三束电子束并到屏幕上。 屏幕包括在第一方向上延伸的荧光线。 电子束在第一方向和第二方向上经受偏转,其基本上垂直于第一方向和荧光线。 荫罩包括细长的狭缝形孔,其在基本平行于荧光线的列中排列。 每个柱中的相邻孔通过掩模中的连接杆彼此分离,并且一列中的连接杆在第一方向上相邻列中的连接杆偏移。 该改进包括位于基本上直线上的交替列中的连杆,其相对于第二方向形成大约2度的角度。
