PURPOSE:To prevent lateral lines at the boundary of each section from being made remarkable, by shifting the display for odd and even number lines by <=two-line's share. CONSTITUTION:The display position of beam spots at the boundary of 15-section toward the vertical direction on a screen at odd and even number fields is shifted for at least <=two-line's share. Thus, signal waveforms v, v' for vertical deflection are changed for odd and even number fields. The boundary of the sections of both the fields can be separated for 4-line's share. As a result, the boundary is replaced at each field and the boundary lines which had conventionally been identified can not be discriminated for the picture on the actual screen, resulting that uniform picture can be obtained vertically. |
