发明名称 Device and method for correcting kinescope scan distortion
摘要 We describe a device and an associated method that includes an EHT signal processing module to generate a compensated gain signal responsive to a first EHT signal. A field fly-back processing module generates a first correcting signal responsive to a first VFB signal. A horizontal scanning correction module generates a predistortion signal responsive to the compensated gain signal. A first digital to analog conversion module converts the predistortion signal into a corresponding analog predistortion signal. A field scanning correction module generates a correcting wave responsive to the compensated gain signal and the first correcting signal. A pulse width modulated module generates a modulated correcting wave by pulse width modulating the correcting wave. A power amplification module generates an amplified modulated correcting wave by amplifying the modulated correcting wave. And a cathode ray tube displays an image responsive to the analog predistortion signal and the amplified modulated correcting wave.
