Embodiment Construction

[0040] The following descriptions of the various embodiments refer 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 [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0041] In the drawings, the thicknesses of layers and regions are exaggerated for clarity of device representation. Like reference numerals refer to like components throughout the specification and drawings.

[0042] Aiming at the technical problem that the frame of the existing OLED display panel is still relatively large, the embodiments of the present invention can...

Abstract

The invention provides an OLED display panel and a display device. A retaining wall of the OLED display panel comprises a substrate retaining wall layer, an inorganic retaining wall layer and an organic retaining wall layer which are stacked, an inorganic retaining wall film and the cross section of the substrate retaining wall layer form an undercut shape, and the substrate retaining wall layer comprises a second flexible substrate. The inorganic retaining wall layer comprises an inorganic layer in the driving circuit layer, and the organic retaining wall layer comprises at least one of a planarization layer, a pixel definition layer and a supporting column. Based on the retaining wall structure, the retaining wall height is increased, the organic materials can be better prevented from flowing, and the distance between the retaining wall and the display area is reduced. Meanwhile, the undercut shape between the retaining wall and the display area can also increase the flow path of theorganic materials, so that the distance between the retaining wall and the display area can be further reduced. Moreover, the cutting cracks can be prevented from extending to the display area alongthe inorganic layer and the substrate, so that the size of a frame can be further reduced to a greater extent.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a display device. Background technique [0002] In OLED technology, a barrier wall is set in the frame area to block the flow of the organic layer of the encapsulation layer to the frame, thereby reducing the area occupied by the frame; however, there are still some areas between the barrier wall and the display area that cannot be displayed. At the same time, when cutting the motherboard, the cutting cracks will extend to the display area. At this time, in order to ensure the quality of the display panel, it is necessary to reserve a larger-sized frame. [0003] That is, the frame of the existing OLED display panel is still relatively large, which needs further improvement. Contents of the invention [0004] The invention provides an OLED display panel and a display device, so as to alleviate the technical problem of large frame size existing in the...
