Abstract

The invention discloses an array substrate, a display panel and a method for manufacturing the array substrate. The array substrate includes a substrate layer, an active layer, a first insulating layer, a first metal layer, a second insulating layer, a second metal layer, an interlayer insulating layer, an organic filling layer and a third metal layer which are disposed in a stacked manner; a mesh-shaped second metal layer is designed in the display area, and is electrically connected with a power supply voltage signal line of the third metal layer through a first via hole to form a double-layer power supply voltage trace structure in the display area. The method comprises the steps of: manufacturing a substrate layer, an active layer, a first insulating layer, a first metal layer, a second insulating layer, a second metal layer, an interlayer insulating layer, a third metal layer, a flattening layer, an anode layer, a pixel defining layer, and a support layer. By connecting the double-layer power supply voltage trace structure in the display area with the power supply voltage (VDD), the resistance voltage drop can be reduced, and the screen brightness uniformity can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a method for manufacturing the array substrate. Background technique [0002] Due to the advantages of light weight, self-illumination, wide viewing angle, low driving voltage, high luminous efficiency, low power consumption, and fast response speed of organic light emitting diode display devices (Organic Light Emitting Display, OLED), the application range is more and more extensive, especially flexible The OLED display device has the characteristics of being bendable and easy to carry, and has become a main field of research and development in the field of display technology. [0003] At present, the bendable display screen has attracted much attention, but the service life of the display screen is seriously affected due to the tensile fracture or cracks in the wiring structure after repeated bending. At the same time, high-end ...
