Abstract
A display device includes a signal detector for detecting gradation pixel data input to a display having multiple pixels, a current detector for detecting currents supplied to at least part of the pixels included in the multiple pixels, and an output part for outputting current data corresponding to currents supplied to the part of the pixels and signal data corresponding to gradation pixel data used for the part of the pixels. Accordingly, it is possible to compare current data with signal data, and therefore, it is possible to confirm whether or not video signals are correctly displayed on a screen.
