Problems solved by technology

When an OLED display screen realizes a full screen and a narrow frame, it is usually necessary to bend the pad bending area of ​​the flexible screen. The metal traces distributed in this area may break, crack, etc. due to stress / strain problems caused by bending. Thus affecting signal transmission, affecting performance and even display failure

Embodiment Construction

[0032] In order to better understand the content of the present invention, the present invention will be further described through specific examples below, but the implementation and protection scope of the present invention are not limited thereto.

[0033] The following description of the embodiments refers to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the attached drawings. direction. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0034] Such as figure 1 As shown, the present invention provides a display panel 100, including: a substrate 101, a dielectric layer 102, a first metal line 103, a planarization layer 104, a cover layer 105, a display layer 106 and a t...

Abstract

The invention provides a display panel and a display device. The display panel comprises a substrate, a dielectric layer, a first metal wire, a planarization layer and a covering layer. The metal wires in the bending area are designed in an undulating manner, so bending stresses aew reducted, and then metal wirings are protected; and due to the fact that the bending areas are bent downwards, the stresses of the film layers far away from the substrate are larger, the metal wires far away from the substrate are set to be narrow in width according to the different bending stresses of the different film layers, the metal wires close to the substrate are set to be wide in width, and the metal wires of the different film layers bear the same stress. The groove bottoms of the grooves close to thebending center line are set to be narrow, the groove bottoms of the grooves in the two sides are the same in width and larger than the groove bottom of the center groove in width, and due to the factthat the bending stress in the center area is larger than that of the grooves in the two sides, the metal wires in different areas can bear the same stress through the arrangement.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode) display screen has become the mainstream display trend due to its self-illumination, wide viewing angle, high contrast, fast response and other characteristics. At present, with people's pursuit of the ultimate display experience, full screens and narrow bezels have become hot spots in display development in the current period. When an OLED display screen realizes a full screen and a narrow frame, it is usually necessary to bend the pad bending area of ​​the flexible screen. The metal traces distributed in this area may break, crack, etc. due to stress / strain problems caused by bending. Thereby affecting signal transmission, affecting performance and even display failure. [0003] Usually metal traces are made as uniform straight lines. When dealing with bending requirement...
