ABSTRACT:
A light generating part generates a first light based on a first control signal. A first driving part outputs a panel driving signal. A display panel receives the first light or a second light that is provided from an exterior to display an image based on the panel driving signal. A sensing part outputs a sensing signal based on the second light. A second driving part compares a reference voltage range with the sensing signal to output the first control signal. The reference voltage range is determined by a first reference voltage and a second reference voltage. Therefore, the light generating part is turned on/off based on the second light to decrease the power consumption of the light generating part, and an operation of the light generating part is stabilized.
