Abstract

A pixel circuit and a display device having the pixel circuit are disclosed. One inventive aspect includes a switching thin-film TFT and a light sensing TFT. The switching thin-film TFT includes a first source electrode electrically connected to a data line. A first gate electrode of the switching thin-film TFT and a second source electrode of the light sensing TFT are electrically connected to a first gate line. A first drain electrode of the switching thin-film TFT and a second drain electrode of the light sensing TFT are electrically connected to a pixel electrode.
