Abstract
This disclosure provides an OLED display panel, an OLED display device, and a method of manufacturing an OLED display panel. The OLED display panel comprises a substrate, OLED devices formed on the substrate, a touch layer, and a conductive isolation layer, the touch layer located on the side of the OLED devices facing away from the substrate, and the isolation layer located on the side of the touch layer facing away from the OLED devices. The surface of the touch layer facing away from the OLED devices conducts an electrical signal after absorbing water vapor. When a finger touches the isolation layer on the upper surface of the OLED display panel, the electrical signal on the surface of the touch layer facing away from the OLED devices can be conducted from the finger through the isolation layer, so that the touch position can be determined.
