Abstract
A display device is described. The device includes an active-matrix luminescence panel that has data lines and pixels for determining luminescence of the pixels. Each pixel includes a driving transistor that converts a signal voltage from a data line into a signal current, and a first switch between the data line and the gate of the driving transistor. The device includes a test current generator to supply a test current to one of the data lines, a voltage detector to detect the voltage of one of the data lines, and a controller to control switches, the test current generator and the voltage detector.
