Abstract
In some embodiments of the disclosed subject matter, a touch sensing pattern recognition array substrate, and related unit, sensor, apparatus, and fabricating method are provided. The sensing unit on the touch sensing pattern recognition array substrate comprises a thin film transistor part and a photosensitive part. The photosensitive part comprises an opaque electrode, a transparent electrode, and a photosensitive layer sandwiched by the opaque electrode and the transparent electrode. The thin film transistor part comprises a gate electrode connected with a scanning line, a source electrode connected with a signal line, and a drain electrode connected with the photosensitive layer of the photosensitive part.
