1. An organic light-emitting display device including a plurality of pixels each having a driving element for controlling current of an organic light-emitting diode (OLED) according to a gate-source voltage of the driving element, comprising:

  • a data modulation module that analyzes input image data in units of a window mask to detect a halftone data block, adjusts a voltage corresponding to grayscale 0 of center data disposed at a center of the halftone data block to a voltage higher than 0V, and adjusts the voltage corresponding to grayscale 0 in a data block other than the halftone data block to 0V,wherein the halftone data block is a data block in which center data of the window mask has grayscale 0 and a number of grayscales higher than 0 exceeds a predetermined threshold value in neighbor data of the center data,wherein a reference voltage higher than 0V is supplied to a source of the driving element, and the voltage corresponding to grayscale 0 is supplied to a gate of the driving element.
