| Popis: | The greater part of the beam current in current color CRTs is blocked by the aperture masks. Consequently relatively high electron beam currents are required to obtain sufficient brightness, and this usually leads to increased beam spot size on the phosphor screen and to inferior spatial frequency reproduction characteristics. In order to remedy this drawback, the usual practice has been to boost the amplitude of the luminance signal in the high-frequency region. Typical of such methods is the so-called "aperture-compensation method". |
