Display panel and display device

Abstract

The present application discloses a display panel and a display device, which relate to the field of display technology and include: a non-display area, a display area at least partially surrounding the non-display area, and a blocking area is further provided between the display area and the non-display area; the display panel further includes : a substrate, an array layer, a light-emitting layer and an encapsulation layer that are stacked in layers; in the blocking area, the array layer includes at least one groove that is recessed toward the substrate, and the light-emitting layer is disconnected at the groove; the encapsulation layer includes a first organic layer, a first The organic layer is located in the blocking area, and the first organic layer is filled in the groove along the direction perpendicular to the light-emitting surface of the display surface; the first organic layer includes a mechano-fluorescent color changing material for detecting the degree of cracks in the blocking area. In the present application, the organic layer in the encapsulation layer is doped with a mechano-fluorescent color-changing material, which can sensitively detect cracks, stop damage in time, and save costs.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light Emitting Diode) has become one of the most competitive technologies in the new generation of display devices due to its wide color gamut, high contrast ratio, energy saving, and foldability. , for example, in the field of smart wearable devices, in-vehicle devices and smart home appliances. [0003] For the existing OLED, after the packaging is completed, the flexible display panel needs to be cut to form light-through holes or some areas for placing functional devices. Usually, laser cutting is used, but laser cutting will produce a partial area of ​​the display panel. At higher temperatures, due to the instantaneous temperature change, cracks may appear at the edges of the light-passing holes of the flexible display panel, and the cracks are lik...

Problems solved by technology

[0003] For existing OLEDs, after the packaging is completed, the flexible display panel needs to be cut to form light holes or some areas where functional devices are placed. Usually, laser cutting is used, but laser cutting will result in partial areas of the display panel. High temperature, due to instantaneous temperature changes, cracks may appear on the edge of the light hole of the flexible display panel, and the cracks are likely to extend to the display area, thereby affecting the performance of the display panel. Cracks enter the display area, causing the display panel to fail. Therefore, there is an urgent need for a convenient method that can detect cracks in time and ensure the effectiveness of the display panel.
