Problems solved by technology
[0004] However, when the existing flexible panels are bent, obvious cracks are prone to appear after folding due to the large-scale existence of inorganic films and the metal traces perpendicular to the bending direction and with a large line width.
Especially in the prior art, the cathode line in the peripheral area of the timing line overlaps with the projected portion of the embankment on the panel, and the bending performance is poor
At the same time, the cathode line in the peripheral area of the timing line, the inorganic film in the peripheral area, especially the cathode line wrapped by the inorganic film above and below, will have obvious cracks when bent
In addition, when the flexible panel is bent, it will also cause the upper and lower film layers (thin film packaging layer) to break, resulting in package failure, signal line short circuit and other abnormalities.

The invention provides a display device and a flexible display panel. The flexible display panel includes a flexible substrate, a dam layer, a light-emitting element and a first electrode layer, wherein the flexible substrate comprises a first side and a second side opposite to each other; the dam layer is located on the first side of the flexible substrate in the direction perpendicular to the flexible substrate, at least one annular dam is formed by the dam layer, and the flexible display panel is divided into a first area and a second area surrounding the first area by the annular dam; thelight-emitting element is located on the first side of the flexible substrate in the direction perpendicular to the flexible substrate, and the light-emitting element is located in the first area in the direction parallel to the flexible substrate; and the first electrode layer located on a first side of the flexible substrate in a direction perpendicular to the flexible substrate, the first electrode layer includes a first electrode wire, the first electrode wire is located between the light-emitting element and the annular dam in a direction parallel to the flexible substrate, and a projection of the first electrode wire on the flexible substrate is not overlapped with the annular dam. Thus, cracks generated by bending can be relieved.
Description
Technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a flexible display panel. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode) technology has developed rapidly and has become the most likely prospective technology to replace LCD (Liquid Crystal Display, liquid crystal display). [0003] OLED display panels can be divided into rigid panels and flexible panels. Compared with traditional display panels, OLED flexible panels have obvious advantages. They are not only lighter and thinner in size, but also lower in power consumption than the original devices. This helps to improve the endurance of the device, and is based on its flexibility and flexibility. , Its durability is much higher than the previous screen, reducing the probability of accidental damage to the device. [0004] However, when the existing flexible panel is bent, due to the large-scale inorganic film and the me...
