摘要： A color display tube device includes a composite correction circuit (31) having a series circuit of a first reactor coil (1) and a first four-pole coil (21) and a series circuit of a second reactor coil (2) with a polarity opposite to that of the first reactor coil and a second four-pole coil (22), the two series circuits being connected in parallel, and a vertical control coil for applying a magnetic bias that changes in synchronization with a vertical deflection current to the first and second reactor coils. The composite correction circuit is connected in series to horizontal deflection coils (3,4). In the color display tube device using an in-line self-convergence system, it is made possible to correct a PQH mis-convergence and reduce pincushion distortion at the left and right occurring before correction by a monitor set while preventing deterioration of the focus performance.

摘要： A color picture tube apparatus having a system for increasing an upper and lower pincushion distortion in the peripheral portion in the vertical direction by making the preliminary vertical deflection force when an electron beam is deflected toward the peripheral portion in the vertical direction of a phosphor screen relatively smaller than the preliminary vertical deflection force when an electron beam is deflected toward the middle portion in the vertical direction of the phosphor screen. With the color picture tube apparatus using an S-shaped distortion correction circuit, an upper and lower inner pincushion distortion can be optimized while correcting the upper and lower pincushion distortion.
