Abstract:
An Organic Light-emitting Diode (OLED) display substrate, a method of forming the same and a display device are provided. The OLED display substrate includes: a driving thin film transistor located on a base substrate and configured to drive an OLED light-emitting unit to emit light; and a photosensitive thin film transistor located on the base substrate and configured to be capable of detecting light emitted by the OLED light-emitting unit and generating an electrical signal, at least a part of film layers of the photosensitive thin film transistor and at least a part of film layers of the driving thin film transistor are disposed at a same layer and made of a same material.
