Abstract

The invention discloses an organic light-emitting diode display panel, a manufacturing method thereof, and a display device, which are used for reducing process steps and reducing production costs. The method includes: depositing a metal thin film layer on a base substrate; forming a source, a drain, and a reflective anode in a pixel region through a patterning process; The to-be-processed metal thin film layer of the semiconductor active layer; coating photoresist on the base substrate that has completed the above steps, exposing and developing the photoresist, exposing the to-be-processed metal thin film layer; performing oxidation treatment on the metal thin film layer to be treated; performing ion implantation and annealing treatment on the base substrate that has completed the above steps to form a semiconductor active layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, organic light emitting diode (Organic Light Emitting Diode, OLED) flat panel display is developing towards the direction of large size and high resolution, high yield, low-cost mass production is gradually advancing in major companies, thin film transistor array technology (TFT Array) It plays a key role in the mass production of flat panel displays. Compared with amorphous silicon thin film transistor (ThinFilm Transistor, TFT), the carrier mobility of oxide TFT is as high as 10cm 2 / Vs is about 10 times that of the former; therefore, the mass production of oxide TFTs has become particularly important. In the process of mass production of the still immature oxide TFT backplane, reducing process steps and controlling costs have always ne...
