Abstract

The invention provides an array substrate, a non-display area located on the periphery of a display area is defined on the array substrate, the array substrate comprises a substrate body, an active layer arranged on the substrate body, common wires arranged on the active layer, voltage dividing electrodes arranged on the same layer as the common wires and bridging lines, the common wires are located on the side, close to the display area, of the non-display area, the active layer comprises a groove located in the non-display area, the groove is formed between the common wires and the voltage dividing electrodes, and the bridging lines are connected with the common wires and the voltage dividing electrodes. By disconnecting the voltage dividing electrodes from the peripheral common wires and connecting the voltage dividing electrodes with the peripheral common wires through the bridging lines after open / short circuit detection, the IGZO in a conductor state can be prevented from connecting the voltage dividing electrodes with a data line to cause short circuit, thereby eliminating the short-circuit path of the voltage dividing electrodes; and therefore, the IGZO type product and ana-Si type product can share the same open / short circuit detection process, and detection equipment does not need to be changed or a detection process does not need to be newly added.

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 large-size and high-resolution display panels, traditional a-Si semiconductor materials can no longer meet the needs of high-end products. Currently, IGZO (Indium Gallium Zinc Oxide) is widely used in large-size display products. material, but due to its own characteristics of IGZO material and a-Si process is not fully compatible. For example, after the active component manufacturing process of the array substrate is completed, the array substrate will be electrically tested to ensure that the active component array has no defects that affect the display quality during the process. However, after the active component manufacturing process is completed, IGZO is in a conductive state. , and the voltage-dividing electrode is connected in series with the peripheral common wiring, ...
