Embodiment Construction

[0047] Embodiments in the present disclosure may be embodied in many different forms. Those skilled in the art can easily understand the fact that the implementation and contents can be changed into various forms without departing from the gist and scope of the present disclosure. Therefore, the present disclosure should not be interpreted as being limited only to the contents described in the following embodiments. In the case of no conflict, the embodiments in the present disclosure and the features in the embodiments can be combined arbitrarily with each other.

[0048] In the drawings, the size of constituent elements, the thickness of layers, or regions may be exaggerated for the sake of 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 scales. In addition, the drawings schematically show ideal examples, and any im...

Abstract

The embodiment of the invention provides a display substrate, a preparation method thereof and a display device. The display substrate comprises a plurality of sub-pixels, at least one sub-pixel comprises a pixel driving circuit, and the pixel driving circuit at least comprises a first transistor serving as a driving transistor and a second transistor serving as a switching transistor; the channel of the first transistor comprises a plurality of sub-channels, and the channel length of the first transistor is the sum of the lengths of the plurality of sub-channels. According to the display substrate, the stability of the driving transistor can be improved, and the problem that a display substrate in the prior art is poor in transistor stability is solved.

Description

technical field [0001] 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 for short) and Quantum-dot Light Emitting Diodes (QLED for short) are active light-emitting display devices with self-illumination, wide viewing angle, high contrast, low power consumption, high The advantages of response speed, thinness, bendability and low cost. With the continuous development of display technology, a display device using OLED or QLED as a light-emitting device and signal-controlled by a Thin Film Transistor (TFT for short) has become a mainstream product in the display field. [0003] The inventors of the present application found that the current display substrate has the problem of poor transistor stability. Contents of the invention [0004] The technical pr...
