Method for correcting digital convergence of multi-mode projection television

A device for correcting digital convergence of multi-mode projection television comprising:

• a remote controller for generating pattern changing data in response to convergence correction;
• microcomputer means for providing adjustment data from memory and for calculating correction data from the adjustment data upon input of the specific mode after storing the adjustment data from the pattern changing data in memory, obtaining adjustment data vectors from the adjustment data, obtaining in advance by interpolation coefficients and initial values for the specific mode for use in finite differential equations and determining correction data for the specific mode;
• correction data storing means for storing the correction data obtained by the microcomputer;
• and
• correction data outputting means for outputting the correction data stored in the correction data storing means to correction current convergent means in response to a control signal of the microcomputer.
