  • Adaptive convergence adjustment for multi-scan monitor
    Patent number: 5939843
    Abstract: The present invention relates to a multi-frequency display system and method for providing color convergence. The system comprises a convergence circuit that is configured to receive a first set and a second set of color input signals. The first of color input signals operates at a first frequency, and the second set of color input signals operates at a second frequency. The system also comprises a controller circuit coupled to the convergence circuit, that is configured to generate a first convergence signal corresponding to the first frequency and a second convergence signal corresponding to the second frequency. The convergence circuit generates a first control signal in response to the first set of color input signals and the first convergence signal. The convergence circuit generates a second control signal based on the second set of color input signals and the second convergence signal.
