Organic EL display apparatus
Abstract:
In an organic electroluminescence (EL) display apparatus, a bus line is provided on an edge of a display unit in a display panel. A feedback circuit unit is provided outside of the bus line, and an output voltage of the feedback circuit unit is applied to a connecting part on the bus line. To the feedback circuit unit, a reference voltage from a reference voltage generating unit is applied, a power supply voltage from a power supply unit is supplied, and a monitoring voltage from the connecting part on the bus line is fed back. The feedback circuit unit includes a switching control circuit and a transistor, and controls, using a feedback, the output voltage by supplying or blocking the power supply voltage to an output terminal, so that a voltage at the connecting point is equal to a target voltage determined by the reference voltage.
