Abstract:
1. An electronic device including a substrate for a luminescence panel that includes data lines and pixels in which a luminescence element can be formed, wherein each of the pixels includes: a driving transistor that has a gate, a source, and a drain, and converts a signal voltage supplied from one of the data lines into a signal current; and a first switch that is provided between the one of the data lines and the gate of the driving transistor, the electronic device comprises: a first circuit path former configured to flow a test current from the one of the data lines through the source and the drain of the driving transistor; a second circuit path former configured to generate a voltage in the one of the data lines, the voltage corresponding to a gate voltage of the driving transistor generated by the test current; and a voltage detector configured to detect, in the one of the data lines, the voltage corresponding to the gate voltage of the driving transistor generated by the test current.
