Abstract:
     Two methods are used in digital convergence correction fot TV monitor, namely, coarse correction and precise correction. The coarse correction may be described as follows: to use a group of correcting pattern which includes a group of adjusting point of measuring and testing pattern. A correcting pattern is choiced by identifying a certain adjusting point which deviates the corresponding basic point most severely. The precise correction may be described as follows: to compare each adjusting point with its corresponding basic point. Owing to the coarse correction, it is favourable to the digit convergence control for TV monitor.
