Problems solved by technology

However, in this process, since the inorganic layer in the encapsulation layer will be formed by chemical vapor deposition, the inorganic layer may be fractured at the undercut, and the fracture of the inorganic layer will lead to encapsulation failure, resulting in water and oxygen intrusion, and Further exacerbating risks when OLED display devices are bent
[0003] Therefore, the existing OLED display device has the technical problem of encapsulation failure caused by the fracture of the inorganic layer in the encapsulation layer at the undercut.

Abstract

The invention provides an OLED (Organic Light Emitting Diode) display panel and an OLED display device. According to the OLED display panel, the filling layer is arranged in the undercut structure, and the filling layer is arranged on the side, away from the auxiliary electrode layer, of the common electrode layer, so that the depth of the undercut structure is reduced or the undercut structure is filled and leveled up by the filling layer, and the segment difference of the undercut structure is eliminated; the depth of the area in contact with the inorganic layer in the packaging layer is relatively low or relatively flat, so that the inorganic layer is prevented from being broken, and packaging failure is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display devices are widely used due to the advantages of self-illumination, fast response, ultra-thin, low power consumption and the like. In order to reduce the voltage drop of the current OLED display device, an auxiliary cathode is provided in the top-emitting OLED display device. By overlapping the auxiliary cathode and the transparent cathode, the voltage drop of the cathode layer is reduced and the display effect is improved. Specifically, the current design of the auxiliary electrode is to design the undercut structure in the OLED display device, so that when the transparent cathode is formed, the transparent cathode can be plated into the lateral etched part, overlap with the auxiliary cathode below, and then form an ...
