PURPOSE: A convergence revising method of a projection television is provided to prevent the deterioration of a screen quality because the scanning line does not incline to one direction. CONSTITUTION: A compensating method of convergence has the steps of: injecting the R, G, B electronic beam deflected by a deflecting yoke to an odd field; injecting the electric beam deflected by the deflecting yoke to an even field located in a place extended as 1/2 H from the odd field; revising the horizontal and vertical convergence to accurately reach to the fluorescent body of a fluorescent face of R, G, B electric beams.
