Abstract
PURPOSE:To minimize the necessary correction amount of convergence, by setting the upper and lower projection tubes featuring the equal horizontal inclination angle into one set and then securing the serial connection for a set of the deflecting coils. CONSTITUTION:Linearity correction resistance 21 and amplitude correction coil 22, linearity correction resistance 23, and amplitude correction coil 24 are connected in series to the coil group of horizontal coils 3B and 5R, the coil group of coils 3G and 5G and the coil group of coils 3R and 5B respectively. The correction is given to the horizontal linearity of the entire screen by linearity correction coil 17, and the virtual alteration is given to the L/R value of the deflecting coil group via the resistance inserted to each coil group. Thus the current of different linearity is obtained when the same voltage is applied to each coil group circuit. Here the raster image of the blue projection tube features the optical projection image, the amplitude of which increases at the beginning of the scan like 20B. Thus the small amplitude is secured previously at the beginning of the scan in order to secure the coincidence to the image of the center red projection tube. As a result, the correction is possible up to maximum lH.
