Abstract
A driver device is provided for an organic EL passive matrix device that achieves reduction in power consumption and suppression of uneven luminance at a low cost. The driver device includes a column driver, a first row driver, a second row driver, a memory, and a power supply/control signal input. An anode of each organic EL element of the organic EL passive matrix device is connected to an output of the column driver, and cathodes in a row are connected together to an input of the row driver. In the driver device, the column driver is disposed in the vicinity of one peripheral side of the IC, and each of the row drivers is disposed in the vicinity of one of the two peripheral sides adjacent to the peripheral side at which the column driver is disposed. These three drivers are packaged on a single integrated chip (IC) chip.
