1. A display device comprising:
a sensor driver receiving firmware from a host in which the firmware is stored, the sensor driver being initialized when a reset signal is supplied from the host, the sensor driver including:
a second memory storing the firmware supplied from the host, and
a sensing unit for supplying a recovery signal corresponding to an abnormal state of the sensor driver to the host while sensing an internal voltage and a clock signal of the sensor driver,
wherein the sensing unit further comprises a clock signal determiner which receives the clock signal of the sensor driver and generates the recovery signal when a frequency of the clock signal of the sensor driver is not within a predetermined range.
