ABSTRACT:
To reduce the variation of luminance between driving modules. Driving modules DR1to DR3each have monitor current output circuits, and output monitor current signals MI12, MI21, MI22, and MI31.A monitor unit of a control circuit converts the monitor current signals into monitor data D12, D21, D22, and D31, respectively, and supplies them to a control data generating unit. The control data generating unit generates current control data CTL1to CTL3such that the values of the respective monitor current signals are equal to each other and supplies them to the driving modules DR1to DR3.
