US 2020/0403179 A1 · OLED DISPLAY PANEL AND OLED DISPLAY DEVICE

Abstract

An organic light-emitting diode (OLED) display panel and an OLED display device are provided. The OLED display panel, by providing an auxiliary water-oxygen barrier layer between the light-emitting functional layer and the substrate, water-oxygen can be isolated by the auxiliary water-oxygen barrier layer even through the gap between the second flexible layer and the second flexible layer and the second barrier layer, thus preventing erosion of the light-emitting functional layer and improving the water-oxygen isolation capacity of the OLED display panels. The technical problem that current active-matrix organic light-emitting diode (AMOLED) display panels, having a poor ability to isolate water-oxygen, is solved.
