Problems solved by technology

However, when the trace 7 passes through the first barrier dam 3 and the second barrier dam 4, it is easy to change the line width at the position of the step difference, resulting in a change in the line resistance, and even short circuit and open circuit problems.

Abstract

The invention discloses a flexible display panel and a display device. A substrate, a first barrier dam, a second barrier dam, an organic electroluminescent structure, a package film layer and routing above the package film layer are comprised. Since at least one opening is arranged in the first barrier dam and the second barrier dam, the routing sequentially runs through the opening in the first barrier dam and the opening in the second barrier dam to extend to the edge of the substrate, the routing does not need to climb a high wall formed by the first barrier dam and the second barrier dam, and large segment difference is avoided. Nonuniform routing width caused by segment difference can be avoided. The problem of routing breaking or short circuit is avoided. Due to the fact that the positive projection of the opening in the first barrier dam on the second barrier dam does not overlap with the opening in the second barrier dam, the waterproof capacity of the barrier dams is not affected by the openings in the first barrier dam and the second barrier dam.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a display device. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode, organic electroluminescence) devices are considered to be the flat panel display devices with the most development potential, and at the same time considered to be the display technology most likely to be made into flexible display devices. [0003] Existing flexible display panels such as figure 1 As shown, it generally includes: a substrate 1, the substrate 1 is defined as a display area and a non-display area, an organic electroluminescent structure 2 is arranged in the display area, a first barrier dam 3 and a second barrier dam 4 are provided in the non-display area, An encapsulation film layer 5 covering the organic electroluminescence structure 2 and the first barrier dam 3 is also provided in the area defined by the second barrier dam 4, and a touc...
