Problems solved by technology

However, as an electronically conductive device, an oxide transistor has excellent switching performance, but when it is used as a driving transistor, it is easily limited by the extremely small sub-threshold swing (S.S. factor) or due to the range of voltage data of the driving chip. Due to the limitation of data range, it is difficult to effectively expand the middle and low grayscale or the anti-interference ability of the stored image data is poor, resulting in poor grayscale transition of the displayed image, which in turn affects the fineness and display uniformity of the displayed image

Abstract

The invention relates to a display substrate, a preparation method thereof and a display device. The display substrate comprises a substrate and a plurality of driving circuits arranged on the substrate. The driving circuit includes a driving transistor and a switching transistor. The driving transistor comprises a first active layer and a first grid electrode located on the side, close to the substrate, of the first active layer. The switch transistor comprises a second active layer arranged on the same layer as the first active layer, and a second grid electrode located on the side, away from the substrate, of the second active layer. According to the display substrate, the preparation method thereof and the display device, the display performance of the display substrate can be improved, and the manufacturing process of the display substrate is simplified.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Active-matrix Organic Light Emitting Diode (AMOLED) display substrates are widely used in the display field due to their advantages of self-luminescence, high contrast ratio, and low power consumption. [0003] At present, the oxide (Oxide) backplane technology is used in the AMOLED display substrate, which has the advantages of simple manufacturing process, excellent device performance and good large-scale uniformity. However, as an electronically conductive device, an oxide transistor has excellent switching performance, but when it is used as a driving transistor, it is easily limited by the extremely small sub-threshold swing (S.S. factor) or due to the range of voltage data of the driving chip. Due to the limitation of data range, it is difficult to effectively...
