  • Digital convergence correcting method and apparatus adopting the same
    Patent number: 5671025
    Abstract: A digital convergence correcting apparatus for a projection-type television set performs an interpolation calculation by employing an auxiliary calculating processor, to thereby perform faster convergence correction. In addition, an OSD block permitting user interface is unified with a test pattern generating block, thereby simplifying the overall hardware structure. A method for operating the digital convergence correcting apparatus is also described.

  • Automatic digital convergence correcting method and apparatus therefor
    Patent number: 5497054
    Abstract: In an automatic digital convergence correction method and apparatus therefore employing a CRT-type display, the vertical and horizontal convergence with respect to the red and green CRTs are tracked based on the ideal seed point within a test pattern generated via the green CRT so that the vertical and horizontal convergence match, to thereby enhance the accuracy of a correction operation and reduce the correction time.
