Abstract
The present disclosure relates to an electroluminescent display device and a driving method of the same. The electroluminescent display device comprises a display panel, including a plurality of data lines, a plurality of sensing lines, a plurality of gate lines, and pixels which are arranged in matrix at each intersection between those lines to form a plurality of display lines; a sensing circuit, for sensing a pixel current in the pixels, integrating the pixel current to obtain a sensing voltage, and generating a sensing data based on the sensing voltage during a sensing operation period; and a compensation unit for calculating a compensation value for electrical characteristics of the pixels based on the sensing data.
