ABSTRACT:
An improved convergence correction apparatus for a projection television and a method thereof which are capable of moving a convergence correction data corresponding to modes to a memory during a mode switching without increasing the capacity of the memory in a projection television, so that it is possible to fabricate a more compact system, for thus reducing the fabrication cost. The apparatus for a projection television according to the present invention includes apparatus for cleansing a semiconductor wafer which includes an EEPROM for storing a correction data corresponding to a picture mode, a microcomputer for reading a correction data stored in an EEPROM (Electrically Erasable and Programmable Read Only Memory) in accordance with a picture mode selection signal from a picture mode judging unit when externally receiving a mode switching signal therein and for transferring the data for a predetermined time, a first switch connected to an address generator and an input terminal of the memory, a second switch connected to an output terminal of the memory, and a read/write controller for switching the first and second switches at high speed, outputting the correction data stored in the memory to a digital/analog converter in accordance with an address from the address generator, and storing the correction data from the microcomputer into the memory.
