Abstract
A convergence control method and apparatus for a projection television are provided. The convergence control apparatus includes an image signal decoder, a convergence control unit, and a main microcomputer. The image signal decoder processes an input image signal and generates a data signal and horizontal and vertical synchronization signals, and a start signal indicating the start of either the horizontal and vertical synchronization signals. The convergence control unit performs convergence adjustment according to a convergence control command it receives, and generates a completion signal when convergence adjustment is complete. The main microcomputer inputs the convergence control command to the convergence control unit when the start signal is input from the image signal decoder, and performs a control operation to display the image signal when the completion signal is input from the convergence control unit.
