Abstract:
Provided is an electroluminescence display comprising a display panel where a plurality of pixels connected to a plurality of data lines and a plurality of gate lines are arranged. Each pixel comprises: a driving TFT that controls the current in a light-emitting element EL in response to a data voltage applied to a gate; and switching TFTs that supply a high-level power supply voltage to the driving TFT in response to a gate-on voltage of an emission signal and control signals applied to the source and drain of the driving TFT. The electroluminescence display switches between first and second modes, the first mode being a mode in which data writing and driving TFT characteristic compensation are performed within 1 horizontal period 1H by applying a data voltage to the gate of the driving TFT, and the second mode being a mode in which data writing is performed within the 1 horizontal period by applying an initial voltage to the gate of the driving TFT and applying the data voltage upon completion of the compensation of the driving TFT characteristics.
