Abstract

The invention provides a display panel, an array substrate, a manufacturing method of the array substrate and a detection circuit. The detection circuit comprises a detection line, a first connection line, an insulating layer and a second connection line, wherein the detection line is arranged along the edge of the array substrate and forms a loop with an opening, a first end and a second end of the detection line are positioned at the position of the opening of the loop, a first end of the first connection line is connected with the first end of the detection line, a second end of the first connection line extends towards a display area of the array substrate to form a first testing end, the insulating layer at least covers the detection line and the first connection line, the second connection line is arranged on the insulating layer and is provided with a bent portion, a first end of the second connection line is connected with the second end of the detection line, the bent portion strides over the opening partially, and a second end of the second connection line extends towards the display area so as to form a second test end.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display panel, an array substrate, a manufacturing method of the array substrate, and a detection circuit. Background technique [0002] With the wide application of liquid crystal display screens, people's requirements for its quality are getting higher and higher. However, during the manufacturing or handling process, it is inevitable that the liquid crystal display will be damaged such as broken corners or cracks. These damages usually appear at the edge of the liquid crystal display, which will lead to poor display effect or even failure to display. Therefore, in order to prevent damaged products from flowing to the market and avoid losses, it is necessary to detect whether the liquid crystal display is damaged before it leaves the factory, so as to screen out damaged products in advance, so as to improve the quality of the manufactured products. [0003] In...
