摘要： In a display apparatus, a light generating part generates a first light in response to a driving signal, and a first driving part outputs a panel driving signal. A display panel receives the first light from the light generating part and a second light externally provided, and displays an image in response to the panel driving signal. A light sensing part is disposed in the display panel so as to output a sensing signal corresponding a light amount of the second light. A second driving part compares the sensing signal with a predetermined reference value, and outputs a driving signal in accordance with the compared result. Thus, the display apparatus may reduce an electrical power consumed to drive the display apparatus.

摘要： 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.
