Abstract

The present invention provides a display panel and a display device. The display device includes the display panel. The display panel includes a display area and a non-display area surrounding the display area. A substrate is disposed in the display area and the non-display area. An inner dam is set in the non-display area, and the inner dam protrudes from the surface of the substrate in the non-display area and surrounds the display area. An outer dam is set in the non-display area, and the outer dam protrudes from the surface of the substrate in the non-display area and surrounds the inner dam. The longitudinal section of the outer dam is an inverted trapezoid. The longitudinal section of the outer dam is the inverted trapezoid and can block crack propagation in an inorganic insulating layer and an inorganic encapsulation layer near a bending line or the cutting line, the packaging quality and display performance of the display device are improved, and at the same time, the display panel achieves a super border effect.

Description

technical field [0001] The invention relates to the field of design and display, in particular to a display panel and a display device. Background technique [0002] Organic electroluminescent display (OLED) has the advantages of self-luminescence, fast response, high contrast, light and thin, low power consumption, wide viewing angle, etc., so OLED display devices have been widely researched and applied. The biggest advantage of OLED devices is that they can realize Flexible display, used in folding portable and wearable products. [0003] At present, flexible display is mainly achieved through thin-film packaging, and the edges of thin-film packaging are easily damaged during bending and deformation. Therefore, how to ensure the barrier performance of the edge is crucial to the life of the flexible display device. [0004] In the thin film encapsulation structure, the inorganic encapsulation layer plays the main role of water and oxygen barrier, and the inorganic encapsu...
