Abstract
A display driver including a crack resistance measurement circuit according to one embodiment of the present disclosure includes a crack resistance measurement circuit connected to a crack resistance circuit of a display panel to measure a crack resistance of the crack resistance circuit, wherein the crack resistance measurement circuit includes a reference resistance generation circuit configured to generate a reference resistance using at least two resistors connected in series and at least two switches connected to correspond to the at least two resistors, a comparator configured to compare a magnitude of the crack resistance with a magnitude of the reference resistance and output a resistance comparison result, and a circuit controller configured to output a reference resistance control signal for controlling the at least two switches according to the resistance comparison result.
