Abstract
A light-emitting diode (LED) display device includes a display part having LED elements arranged in a matrix structure including scan lines and data lines. The LED display device also includes a scan driver driving the scan lines and each of the scan lines is controlled using a discharge voltage at a discharge timing. The LED display device also includes a data compensation part which compensates driving data of each of the data lines to generate the compensation data of each of the data lines using a compensation value to compensate for a difference in luminous intensity slope of the LED element due to a difference in the number of luminescence data lines at the unit scan timing. Thus, a crosstalk phenomenon of the display image due to a difference in the number of data lines simultaneously sourced is decreased.
