Abstract
A convergence correcting apparatus and method of a television for automatically correcting convergence in consideration of terrestrial magnetism of a television location set by a user. Convergence is adaptively corrected in consideration of the terrestrial magnetism of a territory at which a television is installed, thereby preventing picture quality from deteriorating due to differences in the terrestrial magnetism of different territories.
Claims9
A convergence correcting apparatus of a television comprising:
- an input portion through which a user inputs a name of a territory where the television is located;
- a storage portion storing position data and basis data for convergence correction corresponding to the position data;
- a controller for reading from the storage portion the basis data for convergence correction corresponding to the territory name;
- and
- an operation unit for applying the basis data for convergence correction, which is received from the controller, to a predetermined convergence operation formula to obtain convergence adjustment data.

A convergence correcting method of a television comprising the steps of:
- (a) determining and inputting the name of a territory where the television is installed;
- (b) reading basis data for convergence correction corresponding to the position data of the territory name input in step (a);
- (c) applying the basis data for convergence correction read in step (b) to a predetermined convergence operation formula to obtain convergence adjustment data;
- and
- (d) applying a voltage corresponding to the convergence adjustment data to correct the convergence.
