Abstract
A method for convergence correction in a projection television display having a monochromatic tube for each of the three primary colors red, green and blue, whose images can be projected on a screen. Each tube has an associated deflection correction device which comprises a convergence circuit. Convergence correction values are determined by measurement using sensors with screen edge locations which cannot be seen. Convergence correction values are calculated for the entire screen by interpolation between these values.
