Example Embodiment

[0082] The embodiments herein may be implemented in a number of different forms. Those skilled in the art can easily understand the fact that implementations and contents can be changed into various forms without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure should not be construed as being limited only to the contents described in the following embodiments. The embodiments of the present disclosure and the features of the embodiments may be arbitrarily combined with each other without conflict.

[0083] In the drawings, the sizes of constituent elements, the thicknesses of layers, or regions may sometimes be exaggerated for clarity. Therefore, any implementation of the present disclosure is not necessarily limited to the dimensions shown in the drawings, and the shapes and sizes of components in the drawings do not reflect true scale. In addition, the drawings schematically show ideal examples, and any implementation of the...

Abstract

The embodiment of the invention provides a display substrate, a preparation method thereof and a display device. The display substrate comprises a first conductive layer, a first metal layer, a metal oxide layer and a second metal layer which are stacked on a substrate, the metal oxide layer comprises a first active layer, the first active layer comprises a channel region, a source transition region and a drain transition region, and the source transition region and the drain transition region each comprise a first region and a second region. The conductivity of the first active layer corresponding to the first region is higher than that of the first active layer corresponding to the second region, or the oxygen element content of the first active layer corresponding to the first region is smaller than that of the first active layer corresponding to the second region, or the thickness of the first active layer corresponding to the first region is smaller than that of the first active layer corresponding to the second region. According to the embodiment of the invention, the number of patterning processes is reduced, the alignment precision of the gate electrode and the channel region is improved, and the electrical characteristics of the thin film transistor are improved.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate to, but are not limited to, the field of display technology, and specifically relate to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) has ultra-thin, large viewing angle, active light emission, high brightness, continuously adjustable light color, low cost, fast response, low power consumption, wide operating temperature range and flexible Display and other advantages, has gradually become a promising next-generation display technology. According to different driving methods, OLED can be divided into passive matrix drive (Passive Matrix, PM) type and active matrix drive (Active Matrix, AM) type. AMOLED is a current drive device, using an independent thin film transistor (Thin Film Transistor, TFT) controls each sub-pixel, and each sub-pixel can be continuously and independently driven to emit light. Acc...
