ORGANIC EL DISPLAY DEVICE

摘要

In the disclosed organic EL display device (1), bus wiring (21) is disposed at the edge of a display unit (20) in a display panel (10). A feedback circuit unit (80) is installed outside of the bus wiring (21), and the output voltage of the feedback circuit unit (80) is applied to a connection section (22) on the bus wiring (21). A baseline voltage from a baseline voltage generating unit (70) is applied to the feedback circuit unit (80) and a power source voltage from a power source unit (60) is supplied to the feedback circuit unit (80), and monitoring voltage is fed back from the connection section (22) on the bus wiring (21). The feedback circuit unit (80) contains a switching control circuit and a transistor, and by means of supplying or cutting off the aforementioned power source voltage to an output terminal, the output voltage is feedback-controlled in a manner so that the voltage of the connection section (22) becomes a target voltage prescribed by the baseline voltage.
