摘要：A video display having raster correction comprises a cathode ray tube (100) witha deflection coil (RH) mounted thereon for raster generation. A deflection amplifier (70)is coupled to the deflection coil (RH) for generating a deflection current therein. Acorrective waveform modulator (65) is coupled to the deflection amplifier (70) forgenerating a first corrective current (I1cor) in the deflection coil (RH). An auxiliary coil(RHC) is mounted on the cathode ray tube (100) for raster correction. An auxiliary coildrive amplifier (110) is coupled to the auxiliary coil (RHC) for generating a secondcorrective current (I2corR) in the auxiliary coil. A first corrective signal (Hc) is coupled tothe waveform modulator (65) for generating raster correction at a first raster edge and asecond corrective signal (CorSR) is coupled to said auxiliary coil drive amplifier (110) forgenerating raster correction at an edge opposite the first raster edge.
