Problems solved by technology

On the basis of COA, placing the spacer on the color filter layer of the array substrate is called POA (PS on Array). The display panel of POA is often provided with a color filter layer in the non-display area, while the array substrate During the production process, the peripheral routing of the non-display area needs to be detected by the peripheral automatic optical inspection AOI (Auto Optical Inspection). Misrecognition, resulting in a large number of error reports, affecting the normal detection of automatic optical detection

The present application discloses an array substrate and a display panel. The array substrate is divided into a display area and a non-display area. The array substrate includes: a substrate and a peripheral track disposed on the substrate corresponding to the non-display area A wire layer, a peripheral color-resist layer and a plurality of first spacers, the peripheral color-resist layer is disposed on the substrate, the peripheral color-resist layer includes a plurality of peripheral color-resistors, and the peripheral wiring layer includes A plurality of peripheral traces, the peripheral color resists and the peripheral traces do not overlap on the projection of the substrate, and the plurality of first spacers are correspondingly arranged on the plurality of peripheral color resists. The present application uses the above solution to reduce the possibility of misidentification during the automatic light detection process.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to an array substrate and a display panel. Background technique [0002] COA (Color Filter on Array) technology is a technology that prepares a color filter layer on an array substrate. The liquid crystal display panel of the existing COA technology combines an array substrate with a color filter layer with a common electrode and a spacer. It is obtained by pairing the opposite substrates, which has the advantages of high aperture ratio and small coupling capacitance. On the basis of COA, placing the spacer on the color filter layer of the array substrate is called POA (PS on Array). The display panel of POA is often provided with a color filter layer in the non-display area, while the array substrate During the production process, the peripheral routing of the non-display area needs to be detected by the peripheral automatic optical inspection AOI (Auto Optical Insp...
