Abstract
A display device can include a display panel including a subpixel having a switching transistor connected to a data line and a sensing transistor connected to a reference line, a driving circuit connected to the data line, a sensing circuit connected to the reference line; and a timing controller. Also, the sensing circuit is configured to in response to applying a first reference voltage to the subpixel during a first sensing period, acquire a first sensing voltage charged in the reference line as a first sampling value when the switching and sensing transistors are turned on and acquire the first sensing voltage charged in the reference line as a second sampling value when the switching and sensing transistors are turned off, and the timing controller determines that the display device has a defect based on a first difference value between the first sampling value and the second sampling value.
