Abstract
Disclosed are an active matrix-based electronic apparatus and a method of driving the same. More particularly, a pixel circuit of an electronic apparatus according to an embodiment of the present disclosure may include a light-emitting driver configured to apply a forward bias to a light-emitting device in an emission mode to control light to be emitted through the light-emitting device; a sensing driver configured to apply a non-forward bias to the light-emitting device in a sensing mode to control an electrical signal corresponding to light incident on the light-emitting device to be generated; and a reader configured to read intensity of light corresponding to the generated electrical signal.
