Abstract

PURPOSE:To have high resolution over the whole picture field by making the horizontally deflecting magnetic field in the form of a barrel having vertical component and the vertical deflecting magnetic field in pin cushion form, and equipping an image signal of electron gun corresponding to each color with a lag time controlled mutually. CONSTITUTION:A deflecting device 30 includes a horizontal deflecting coil 31, vertical main deflecting coil 32, vertical aux. deflecting coil 33, and ferrite core 34. The horizontally deflecting magnetic field is made in barrel form and generated by the horizontal deflecting coil 31, while the vertically deflecting magnetic field in weak pin cushion form and generated by the vertical main deflecting coil 32. A delay circuit 27 gives mutually controlled delay times to the distribution signal for three electron guns, to correct misconvergence at the horizontal ends and diagonal ends of the picture field, while the vertical aux. deflecting magnetic fields is generated to correct misconvergence at the vertical ends and diagonal ends of the picture field. Thereby distortion of the beam spot shape is eliminated approximately, and a high resolution can be obtained over the whole picture field.
