Array substrate and preparation method thereof and display panel

Abstract

The invention provides an array substrate and a preparation method thereof, and a display panel. The array substrate comprises a bending region and non-bending regions, and also comprises: a substratelayer; an inorganic stacking layer arranged on the substrate layer, wherein a groove is formed in the bending region of the inorganic stacking layer, first metal wires are arranged in the inorganic stacking layer, and are located in the non-bending regions on the two sides of the bending region; a filling layer filled in the groove; and a second metal wire arranged on the inorganic stacking layerand the filling layer, wherein the first metal wires on the two sides of the bending region are in lap joint through the second metal wire. According to the array substrate, only one layer of patch cord is adopted in the bending region to achieve conduction of signals on the two sides of the bending region, so that the problems that according to a traditional structure, due to the fact that multiple layers of patch cords are needed to achieve conduction of signals on the two sides of the bending region, the circuit resistance of the bending region is large, and switching contact is poor are solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display panel. Background technique [0002] LTPO (Low Temperature Polycrystalline Oxide) is a low-power OLED display technology, and LTPO TFT has lower driving power than LTPS TFT. LTPS (low temperature polysilicon) products need 60Hz to display still images, but LTPO products can be reduced to 1Hz, and the driving power is greatly reduced. LTPO products convert part of low-temperature polysilicon transistors into oxide semiconductor transistors, so there is less leakage current, and the capacitor voltage (charge) can be maintained for one second to drive 1Hz. LTPS products have a large leakage current, and even driving static pixels requires 60Hz; otherwise, the brightness will be greatly reduced, while LTPO products will not. Therefore, LTPO products with lower power consumption are more and more sought aft...
