Abstract:
1. A display device, comprising: a power supplying unit configured to output a high-side output potential and a low-side output potential; a display unit in which a plurality of pixels are arranged and which receives power supply from the power supplying unit; a voltage detecting unit configured to detect a high-side applied potential applied to a first pixel in the display unit and a low-side applied potential applied to a second pixel in the display unit, the second pixel being different from the first pixel; and a voltage regulating unit configured to regulate at least one of the high-side output potential and the low-side output potential outputted from the power supplying unit such that a potential difference between the high-side applied potential and the low-side applied potential reaches a predetermined potential difference, wherein each of the pixels includes a driver and a luminescent element, the predetermined potential difference is a potential difference expressed as VTFT+VEL−ΔV+Vdrop, where VTFT is a voltage required by the driver, VEL is a voltage required by the luminescent element, ΔV is a potential difference between a potential output by the power supply and a potential of a pixel detected by the voltage detecting unit, and Vdrop is a voltage margin corresponding to ΔV.
