  • Patent number: 6498629
    Abstract: A Circuit for conditioning sync signals for devices for the line-by-line Display of video signals includes, a first input for horizontal sync signals (H1sync, H2sync), a second input for vertical sync signals (Vsync), and a delay stage. The delay stage outputs a signal (Vshift) which is delayed relative to the vertical sync signal (Vsync) by a specific delay time (reg). The circuit determines the timing of the horizontal sync signals (H1sync, H2sync) relative to the vertical sync signal (Vsync) and/or relative to the delayed signal (Vshift). The delay stage is designed in such a way that the delay time (reg) is adjustable.

  • Patent number: 6295100
    Abstract: A method for convergence correction in a television receiver and to a television receiver, in particular a projection television receiver having in each case one monochromatic picture tube for the three primary colours, red, green and blue, improves the quality of convergence correction. Each picture tube is assigned a correction device which comprises a convergence circuit. The convergence circuit is assigned a memory in which correction values for the convergence correction of the three picture tubes are stored. In accordance with the correction values, the convergence circuit generates output signals, which are output to a correction device, which in each case comprise at least one correction coil and, for each correction coil, one driver circuit. A correction current is applied to the associated correction coil in order to correct image defects of a picture tube.

  • Patent number: 6281951
    Abstract: The invention relates to a television receiver, in particular a projection television receiver having red, green and blue monochromatic picture tubes, the images of which are projected onto a picture screen. Each picture tube is assigned a correction device comprising a convergence circuit. The convergence circuit is assigned a memory in which correction values for the convergence correction of the three picture tubes are stored. In accordance with the correction values, the convergence circuit generates control signals, which are output to at least one correction coil where each correction coil has one driver circuit. A correction current is applied to the associated correction coil to correct image defects visible on each picture tube.
