ABSTRACT:
A passive matrix type display device includes: a display unit having a display area; first electrodes on the area for switching between a conductive state and a non-conductive state; second electrodes on the area; a driving current source for supplying a driving current to the second electrodes; light-emitting elements at an intersection between the first and second electrodes; a first circuit for controlling a part of first electrodes to the conductive state and for scanning the first electrodes; a second circuit for deciding a part of second electrodes corresponding to a part of light-emitting elements emitting a light; light-emission adjustment elements coupled with the second electrodes for branching an adjustment current from the driving current; and a light-emission adjustment controller for controlling the light from each light-emitting element by controlling the adjustment current.
