Abstract
A measurement device includes a power supplier including a first terminal through which a first power voltage is output and a second terminal through which a second power voltage is output, the power supplier being configured to receive a first current from the first terminal to measure a power current of a display device and to receive a second current from the second terminal to measure a luminance of the display device; a switching circuit including a first switch configured to selectively connect a power terminal of the display device to the first terminal or an internal voltage terminal of the display device through which an internal voltage of the display device is output; and a luminance sensing circuit configured to receive the second power voltage and to generate the second current corresponding to the luminance of the display device.
