ABSTRACT:
A display area of a display panel is divided into a plurality of areas, and a current detector detects a driving current (i.e. CV current) that flows when light is emitted from an area or a block including a plurality of areas. Such current detection is repeated while sequentially changing the target area or block and a CPU detects an area that has a current value different from that of other areas (i.e. an area that requires correction) based on results of the results of current detection. A similar process is performed on smaller areas obtained by subdividing the area to find a smaller area that requires correction. Thus, a correction value is obtained for each pixel and the correction values are efficiently calculated.
