Abstract: A crack detector may include a plurality of crack detection switches for connecting and disconnecting data lines of a display panel to one another. A signal supply may supply a detection control signal for controlling opening/closing of the crack detection switches and supply a crack detection signal to a first data line. A crack determiner may be configured to determine a crack of the display panel by comparing an output signal supplied from a second data line connected to the first data line through one of the crack detection switches, with a preset reference value.

Abstract: A display device and a method of driving the same are described. The display device includes: an over driver to overdrive current frame data included in input image data to output overdriving frame data; a data driver to generate a data signal for the current frame data based on the overdriving frame data; and a display panel including a plurality of pixels to receive the data signal, the over driver may calculate a temporal change rate or a spatial change rate of the input image data, and output the overdriving frame data utilizing a reference formula having a first main parameter determined according to the calculated result. Therefore, overdriving may be performed dynamically according to the spatial change rate or the temporal change rate of the input image data.
