Abstract: A display apparatus includes: a display panel including a first region and a second region; a controller to process source data and to generate an image signal; a timing controller to generate a driving signal for driving the display panel based on the image signal; and a cable connected to the display panel and to transmit the driving signal to the display panel. The controller transmits, to the timing controller, a pattern image signal for displaying a pattern image on the first and the second regions in a sequential manner; and determines a connection state of the cable based on (i) a first current value, which is output based on the pattern image displayed in the first region and (ii) a second current value, which is output based on the pattern image displayed in the second region.
