ABSTRACT:
To reduce degradation of image quality when constructing anode line drive circuits in a display panel drive circuit from a plurality of IC chips. Dummy drive output and proper drive output of an adjoining IC chip are switched in predetermined cycles and supplied to an anode line. This makes it possible to reduce variation in adjacent output currents among IC chips. Thus, it is possible to reduce luminance differences in display areas caused by differences in current driving capacity among IC chips and reduce degradation of image quality when an anode line drive circuit is constructed from a plurality of IC chips.
