Abstract
The display device of the present disclosure may comprise a display panel equipped with pixels each representing image data and photo sensors each outputting an electric signal through a sensing line responding to light, a data driving circuit providing a data voltage corresponding to the image data to the pixel through a data line, a gate driving circuit supplying, through a gate line, a scan signal for controlling an application of the data voltage to the pixel disposed on a horizontal line and for controlling a connection of the photo sensor disposed on a corresponding horizontal line and the sensing line, a sensing driving circuit outputting digital sensing data by summing the electric signals of two photo sensors disposed on different horizontal lines and sharing the sensing line; and a timing controller supplying control signals for controlling the data driving circuit, the gate driving circuit and the sensing driving circuit.
