摘要:
A display device according to the present disclosure includes: an organic EL display unit having pixels; a variable voltage source which supplies a voltage to the organic EL display unit; and a voltage drop amount calculating circuit which regulates the voltage output by the variable voltage source, according to video data, in which the organic EL display unit further includes an anode-side power source line network and a cathode-side power source line network connected to the pixels and the variable voltage source, for supplying the voltage from the variable voltage source, and the voltage drop amount calculating circuit estimates, from the video data, a distribution of voltage drop amount in the anode-side power source line network and the cathode-side power source line network for each of the pixels, and regulates the voltage based on the estimated distribution of voltage drop amount for each of the pixels.
