Abstract
An OLED display panel and a manufacturing method of the OLED display panel are provided. A light-transmissive hole is in the OLED display panel, a blocking wall is arranged outside some sub-pixel regions around the light-transmissive hole, and a thin-film encapsulation layer is on the blocking wall. A portion of light emitted from the sub-pixel regions inside the blocking wall is reflected at an interface of the thin film encapsulation layer by total internal reflection to cause a bright light spot, so that an image can also be displayed in the light-transmissive hole. Therefore, an opening for an under-screen camera less affects aesthetics and appearance integrity of the OLED display panel.
