Embodiment Construction

[0035] Specific implementations of an array substrate, a manufacturing method thereof, a display panel, and a display device provided by embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] The inventors have found in their research that thin film transistors (Thin Film Transistor, TFT) are important components in various circuits of display devices, and have been widely used in liquid crystal displays (Liquid Crystal Display, LCD) and organic electroluminescence (Organic Light- Emitting Diode, OLED). In the prior art, since the manufacturing process of amorph...

Abstract

The invention discloses an array substrate, a fabrication method thereof, a display panel and a display device. By arranging a first thin film transistor and a second thin film transistor in an electrostatic protection circuit, materials of a first active layer in the first thin film transistor and a second active layer in the second thin film transistor both comprise poly-silicon, thus, the electron mobility of the first active layer and the second active layer is improved, the switch characteristics of the first thin film transistor and the second thin film transistor are further improved, electrostatic charge on a signal line can be rapidly released, signal transmission delay is reduced as well as normal signal transmission is ensured, and the effect of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, a display panel and a display device. Background technique [0002] With the continuous development of display technology, display screens or touch screens have been widely used in people's lives. Among them, Liquid Crystal Display (LCD) has the characteristics of small size, low power consumption, and no radiation, and occupies an important position in the market. status. Organic Light-Emitting Diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, light and thin, etc., and has been widely used in the market. [0003] In order to realize the display function, a variety of signal lines are distributed on the display panel, such as gate lines, data lines, etc., and in order to increase the transmission capacity of the signal lines and avoid the influence of static...
