GREEN CONVERGENCE CORRECTION METHOD OF PROJECTION TV

摘要

PURPOSE: A green convergence correction method of a projection TV is provided to prevent a color spread by preventing a green location from being deviated from a standard location. CONSTITUTION: In a green convergence correction method of a projection TV, a +-shape pattern(22) is extended left and right vertical lines and upper and lower horizontal lines on a screen. The +-shaped pattern(22) is adjusted to be coincided with a central +-shape pattern(12) so that the green convergence is exactly corrected, thereby preventing a green location from being deviated from a standard location.
