Original Abstract Submitted

The present disclosure relates to an image display apparatus and a video wall including the same. The image display apparatus according to an embodiment of the present disclosure includes: a panel with a plurality of light emitting diodes; and a driving controller configured to output a scan signal to the plurality of light emitting diodes during each of a plurality of subframe periods, wherein, in response to the gray level of a frame including a plurality of subframes being above a predetermined level, the driving controller outputs a data signal based on pulse width modulation to the light emitting diodes, and in response to the gray level of the frame being below the predetermined level, the driving controller outputs a data signal based on pulse amplitude modulation to the light emitting diodes while dividing the gray level of the frame and distributing the divided gray level across at least part of the subframes. Accordingly, it is possible to efficiently reduce flicker.
