Abstract
A display apparatus includes a display panel which receives a light, a backlight which provides the light to the display panel in response to a driving voltage, and a backlight driver which applies the driving voltage to the backlight. The backlight is turned on and off during a communication period to transmit data to an external receiver using visible light communication during the communication period. The backlight driver controls a voltage level of the driving voltage according to a number of turn-on periods of the driving voltage during the communication period.
