Chemical sensing unit, chemical sensor, and chemical sensing device electrically coupled to light emitting diode
Embodiments of the present disclosure relate to the field of electronic sensing technologies, and provide a chemical sensing unit, a chemical sensor, and a chemical sensing device. The chemical sensing unit includes a thin film transistor arranged on a substrate, and a light emitting diode coupled to the thin film transistor. The thin film transistor includes a semiconductor active layer, a source, and a drain, and the semiconductor active layer is mainly composed of a chemically sensitive semiconductor material. The chemical sensing unit is provided with a via hole in a region between the source and the drain, such that the semiconductor active layer is exposed at a position corresponding to the via hole. The light emitting diode includes a first electrode, a light-emitting functional layer, and a second electrode which are stacked in sequence, wherein the first electrode is coupled to the drain.
