Abstract

The invention discloses a display panel and a display panel detection method. The display panel is provided with a display area and a packaging area arranged around the display area. The display panel comprises an array substrate, a light emitting layer, a frame glue part and a packaging layer. The light emitting layer is located on the array substrate and at least partially arranged in the display area. The frame glue part is arranged in the packaging area, and the frame glue part and the light emitting layer are arranged on the same side of the array substrate. The packaging layer is arranged on the sides, away from the array substrate, of the light emitting layer and the frame glue part. Packaging of the display panel is achieved through laser sintering of the frame glue part. In order to prevent the edge of a laser spot from entering the display area during laser sintering, the display panel further comprises a reflecting part, which is arranged on the surface of the side, facing the array substrate, of the packaging layer and is at least located in the partial area, close to the display area, of the packaging area. The edge position of the current laser spot can be determined through the laser reflected by the reflecting part, and the situation that the laser enters the display area to damage devices in the display area, and the yield of the display panel is affected is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display panel and a detection method for the display panel. Background technique [0002] At present, due to the requirement of a narrow frame screen body of the display panel, when designing the frame of the display panel, it is necessary to compress the lateral distance between each film layer, especially the distance between the packaging area and the display area. However, when performing laser sintering on the packaging area, on the one hand, to ensure the reliability of the packaging, it is necessary to use a laser with a larger laser spot radius; The edge of the laser spot enters the display area, causing the display pixels to be burned. Therefore, under the premise of ensuring the reliability of the sealing frame, it is necessary to prevent laser light from entering the display area from causing damage to devices in the display area. [0003] T...
