Abstract

The invention provides an array substrate and a display panel. According to the array substrate, a first power supply voltage line is formed on a second metal layer of the array substrate, a first viahole is formed in the interlayer insulating layer, a first power supply voltage line on the second metal layer is connected with a second power supply voltage line of the source-drain electrode layerthrough a first via hole, at least two connections exist between the first power supply voltage line and the second power supply voltage line, parallel connection of the first power supply voltage line and the second power supply voltage line is ensured, therefore, the impedance of the power supply voltage line is reduced, the problem of voltage drop on the power supply voltage line is relieved,a film layer does not need to be added, the thickness of the display panel is not influenced, and the technical problem of uneven brightness of the display panel due to the voltage drop on the power supply voltage signal line of an existing display panel is relieved.

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] The existing OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel is widely used due to its advantages of being bendable, light and thin, and high color saturation. Low-temperature polysilicon array substrates are used in OLED display panels, but low-temperature polysilicon During the manufacturing process of the array substrate, the threshold voltage drift of the thin film transistor may occur due to manufacturing problems, so it is necessary to compensate the driving circuit of the low-temperature polysilicon array substrate. [0003] The existing pixel compensation circuit includes a first metal layer, a second metal layer and a source-drain layer, wherein the source-drain layer prepares the VDD signal line, that is, the power supply voltage signal line, and the VDD signal...
