Abstract:
1. An organic EL drive circuit for current-driving an organic EL display panel by generating drive currents or a current, on which the drive currents are generated, correspondingly to respective output terminals connected to a number of column pins or terminal pins, comprising: a plurality of current generator circuits provided correspondingly to the output terminals for generating predetermined currents correspondingly to the output terminals, respectively; a plurality of current sources provided correspondingly to the output terminals and, in response to the predetermined currents from the current generator circuits correspondingly to the output terminals, for generating the drive currents or the current, on which the drive currents are generated, correspondingly to the output terminals, respectively; and a plurality of selection circuits provided between the current generator circuits and the current sources correspondingly to the output terminals, respectively, wherein the selection circuits select the predetermined current of the current generator circuits corresponding to the output terminals assigned to the selection circuits or the predetermined current from the current generator circuits corresponding to the output terminals adjacent to the current generator circuit, correspondingly to a row side scanning or a scan line scanning.
