Abstract: The display device according to the present disclosure may comprise a display panel equipped with a plurality of pixels and a plurality of photo sensors, a data driving circuit, a gate driving circuit, and a timing controller. The source drive IC included in the data driving circuit may comprise a DAC, one or more sensing units to receive an electrical signal from the photo sensor in a display period and to receive a sensing signal from the pixel in a blank period, and an ADC to convert the signal output from the sensing unit into digital data.

Abstract: A display device capable of driving at low speed includes a display panel, on which display lines each including a plurality of pixels are formed, a driver unit for driving the pixels, and a timing controller which controls an operation of the driver unit and includes a first control logic unit and a second control logic unit. When a mode conversion control signal of an on-level is input during a normal drive, in which a length of one frame is set to P, the first control logic unit expands a length of one frame for a low speed drive to (n×P), where n is a positive integer equal to or greater than 2, assigns a length P to each of n sub-frames included in the one frame for the low speed drive, and controls the operation of the driver unit in an interlaced low speed driving scheme.
