Abstract
An electroluminescent display device includes a display panel including a plurality of pixels connected to a plurality of sensing lines, a plurality of sampling circuits configured to simultaneously sample driving characteristics of the pixels to generate sampling outputs, a plurality of sampling multiplexers configured to divide the sampling outputs into n groups and to alternately select group sampling outputs, a plurality of scalers individually connected to the sampling multiplexers, and a global multiplexer configured to selectively connect outputs of the scalers to an analog-to-digital conversion circuit, wherein the number of scalers is less than the number of sampling circuits.
