DIGITAL CONVERGENCE CORRECTION CIRCUIT AND DISPLAY DEVICE EMPLOYING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a digital convergence correction circuit that can reduce disturbance in the convergence caused when a CPU operates a memory at adjustment of the convergence. SOLUTION: In the case that an address changeover device 112 is controlled to select a first address signal outputted from an address generator 111 and a data changeover device 114 is controlled to connect a memory 113 and a selector 117, the selector 117 controls the selection of an output of the data changeover device 114, and in the case that the address changeover device 112 is controlled to select a second address signal outputted from a CPU 140 and the data changeover device 114 is controlled to connect the memory 113 and the CPU 140, the selector 117 controls each section of a digital convergence circuit to select the output of a storage means 116.
