A light-detecting device structure comprises a substrate, a vertical organic light-emitting transistor and a light-detecting unit, wherein the vertical organic light-emitting transistor is disposed at a first location on the substrate, and the light-detecting unit is disposed at a second location on the substrate, in which the first and the second locations can be spaced out an appropriate distance as needed. The vertical organic light-emitting transistor emits a light to an object, and the light-detecting unit receives a reflected light from the object. The reflected light received is analyzed to determine a distance between the light-detecting device structure and the object, as well as a shape or a composition of the object.
