Abstract
A display device capable of accurately sensing object presence at lower power consumption is presented, as well as a method of driving the display device. The display device includes a sensing circuit that detects the presence of an object by sensing radiation, and a radiation source array that provides radiation to the sensing circuit. First signals are provided to the scan lines of the sensing circuit, sequentially activating the sensors during a frame period. Second signals are provided to a radiation source array to selectively activate different portions of the radiation source array. The first and second signals are synchronized in their timing such that the portion of the radiation source array that supplies radiation to the activated sensors are turned on.
