Abstract
The electroluminescent display device according to the present disclosure comprises a plurality of pixels. Each of the plurality of pixels comprises a driving element for generating a driving current, a light emitting element for emitting light according to the driving current, an emission controlling element for controlling a flow of the driving current between the driving element and the light emitting element, and a switching circuit for setting a first gate-source voltage of the driving element corresponding to the driving current based on a first data voltage during a first period and setting a second gate-source voltage of the driving element based on a second data voltage different from the first data voltage during a second period following the first period, wherein the second gate-source voltage is different from the first gate-source voltage, and wherein during the second period the emission controlling element is turned off.
