Abstract:
A display device includes a display panel, a data driving circuit, and a timing controller, wherein the display panel includes a plurality of gate lines to which a scan signal is applied, a plurality of data lines to which a data voltage is applied, a plurality of reference voltage lines to which a reference voltage is applied, and a plurality of subpixels, wherein the data driving circuit senses a voltage on one reference voltage line selected from the plurality of reference voltage lines in a first detecting period and a second detecting period having different voltage detecting paths, and wherein the timing controller controls the data driving circuit, and determining whether or not the reference voltage line is abnormal using a sensing voltage detected from the reference voltage line.
