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.

Abstract translation: 显示装置包括接收光的显示面板，响应于驱动电压而向显示面板提供光的背光，以及将驱动电压施加到背光源的背光驱动器。 在通信周期期间，背光源被打开和关闭，以在通信时段期间使用可见光通信将数据发送到外部接收器。 背光驱动器根据通信期间的驱动电压的接通时间的数量来控制驱动电压的电压电平。
