Abstract
PURPOSE: To suppress a moire within a permissible range without increasing the size of an electron beam by previously setting the range of a scanning line interval according to electron beam characteristics and sequentially determining the scanning range according to the number of scanning lines and screen effective height. CONSTITUTION: Ranges 2a-2c of scanning line intervals for maintaining a moire viewed on a screen within the permissible range are previously set according to the electron beam characteristics. The half value D50 of the beam characteristics is standardized with a shadow mask pitch (a), the scanning line interval S is characterized as characteristics of scanning lines with the pitch 8, and the range of intervals is inside respective triangles. The scanning line interval Δhi is determined in order according to the number N of scanning lines, effective screen height H, and the maximum and minimum values between scanning lines. The view of the moire is suppressed within the permissible range without increasing the electron beam size or causing a decrease in resolution, thereby obtaining an image of good resolution and good quantity.
