DISPLAY DEVICE

摘要

Provided is a display device with a strong power consumption minimizing effect. This display device (100) comprises: a variable voltage source (180) which outputs a power source voltage; an organic electroluminescence display unit (110) which includes anode-side and cathode-side power source lines which are connected to each of a plurality of light-emitting pixels (111); a potential difference detection circuit (170) which detects an anode side potential of a monitor light-emitting pixel (111M); a voltage decrease quantity computation circuit (150) which, from the video data, calculates a voltage decrease quantity which arises in the cathode-side power-source lines and estimates the potential in at least one point of the cathode-side power supply lines; and a signal processing circuit (160) which adjusts the power source voltage which is outputted from the variable power source (180) such that the potential difference between the anode-side potential which is detected with the potential difference detection circuit (170) and the cathode-side potential which is estimated with the voltage decrease quantity computation circuit (150) is a prescribed potential difference.
