Driving apparatus and driving method of electroluminescent display device

A driving apparatus of an electroluminescent display device including a display panel provided with a plurality of pixel rows including a set of pixels, includes: a pixel row determiner configured to select a representative pixel row disposed at a position where an accumulated stress caused by repeated display of an input image is maximum from all pixel rows; an overdrive control (ODC) controller configured to select a sampled pixel characteristic value from pixel characteristic values representing the pixel rows, and selectively output a first ODC control signal and a second ODC control signal based on a magnitude of the sampled pixel characteristic value; and a sensing driving circuit configured to pre-sense a pixel characteristic value representing a pixel row in a first sensing period, perform one ODC sensing on pixel characteristic values of all pixel rows according to a first ODC control signal, respectively, in a second sensing period after the first sensing period, and perform one ODC sensing on pixel
