Abstract

The embodiment of the present invention discloses an array substrate and a display panel. The array substrate includes a substrate, a first gate layer formed on the substrate; a first insulating layer and an active layer formed sequentially on the first gate layer. , a source-drain layer and a second insulating layer; and, a second gate layer formed on the second insulating layer; the first gate layer includes a plurality of first gates, and the second gate layer includes a plurality of first gates Two gates; wherein, the first gate layer further includes a first gate line connecting multiple first gates, at least two second gates are connected to the same first gate; or, the second gate layer It also includes a second gate line connected to a plurality of second gates, at least two first gates connected to the same second gate. The embodiment of the present invention improves the structure of the array substrate, increases the storage capacitance of the sub-pixel while increasing the carrier mobility of the thin film transistor of the array substrate, reduces the capacitance of the gate line, and further improves the display effect of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display panel. Background technique [0002] With the development of display technology, liquid crystal display devices (Liquid Crystal Display, LCD), organic light emitting diode display devices (Organic Light Emitting Display, OLED) and other flat display devices have the advantages of high image quality, power saving, and thin body. It is widely used in various electronic products such as mobile phones and TVs. Thin film transistors are widely used in various display devices as switching components and driving components. They can be provided with top gates and bottom gates on both sides of the active layer to form a double gate structure, and the active layer can be driven by the double gates. , can effectively improve the carrier mobility and maintain the stability of the thin film transistor. [0003] However, when the thin film transisto...
