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.
