Patent ID: 7880818

Claim:
A device comprising: an EHT signal processing module to generate a compensated gain signal responsive to a first EHT signal; a horizontal scanning correction module to generate a predistortion signal responsive to the compensated gain signal; a first digital to analog conversion module to convert the predistortion signal into a corresponding analog predistortion signal; a field fly-back processing module to generate a first correcting signal responsive to a first VFB signal; a field scanning correction module to generate a correcting wave responsive to the compensated gain signal and the first correcting signal; a pulse width modulated module to generate a modulated correcting wave by pulse width modulating the correcting wave; a power amplification module to generate an amplified modulated correcting wave by amplifying the modulated correcting wave; and a cathode ray tube to display an image responsive to the analog predistortion signal and the amplified modulated correcting wave.
