Problems solved by technology

However, due to the external stress, the barrier film in the frame area is prone to cracks, which further leads to the disconnection of the signal lead-out lines arranged under the barrier film.
[0004] Therefore, when the OLED display panel in the prior art is subjected to external stress, the phenomenon of disconnection of the signal line is likely to occur, thereby affecting the display effect of the picture.

Abstract

The invention discloses an OLED display panel and an OLED display device, which are used to avoid the disconnection of signal lines when the OLED display panel is subjected to external stress, thereby improving the display effect of the picture. The OLED display panel includes: a substrate; the substrate includes a display area and a stepped area adjacent to the display area; the display area includes an OLED light-emitting device; a signal lead wire electrically connected to the OLED light-emitting device, The signal lead-out line extends to the step area; the barrier film is arranged on the OLED light-emitting device and completely covers the OLED light-emitting device, and the edge of the barrier film has at least one pointed structure; wherein, the signal The projection of the lead-out line in the direction perpendicular to the substrate does not overlap with the projection of the sharp corner portion of the pointed structure in the direction perpendicular to the substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique [0002] Currently, among display devices, organic light emitting diode (Organic Light Emitting Diode, OLED) display screens have become a hot spot for high-end smart products. Since the organic light emitting diode display has self-luminous properties and does not require a separate light source, the thickness and weight of the display can be reduced. [0003] Generally, an OLED display panel has a display area and a frame area surrounding the display area, wherein the display area is provided with light-emitting devices, and the frame area is provided with display signal leads for providing display signals to the display area. Wherein, the frame area includes a stepped area for binding display signal lead wires and the printed circuit board. Specifically, such as figure 1 As shown, the OLED display panel...
