Zusammenfassung:	A display apparatus is provided to compensate for EMI(ElectroMagnetic Interference) characteristic by setting exactly a reference pattern for adjusting convergence without deviation. A display apparatus includes plural sensors(a1-a20) and a controller. The sensors include a pair of first regions and a pair of second regions. The first regions are disposed opposite to each other along a first direction of a frame, which supports a screen for display images. The second regions are disposed opposite to each other along a second direction across to the first direction. The controller compares the beam amount of the images with a reference beam amount at cross sections between the first and second regions, and adjusts convergence value according to the comparison result.
