Digital convergence correction device and display device

摘要

A problem to be solved by the invention is to provide a digital convergence correction device capable of coping with variation in scanning frequency at a reasonable price. The digital convergence correction device comprises a gate circuit for storing a variation in each convergence correction amount in a memory as correction data, and reading out the correction data synchronously with screen scanning at the time of integrating the correction data and causing the output time to be constant for each of the correction data read out.
