Abstract
A safety driving system of a display device includes a display panel including at least one conductive detection line, the conductive detection line extending in a predetermined area of the display panel and being configured to detect voltage variation according to damage in the predetermined area, a panel detector configured to apply a reference voltage to one end of the detection line, to receive an output voltage corresponding to the reference voltage through the detection line from another end of the detection line, to compare the received output voltage with a predetermined normal voltage range, and to generate and output a detection result signal, and a controller configured to provide a detection set value for driving the panel detector and to interrupt the driving of the display panel when the output detection result signal indicates that the display panel is damaged.
