Abstract
This paper proposes a new digital convergence system which calculates the compensation data based on the 2nd and 4th degree Lagrange interpolating polynomials, using a real time chip, and it requires only a small memory space. Experimental results by actual implementation showed that the proposed system is much more efficient than conventional systems. The proposed convergence technique can improve the performance of projection TVs
