  • OLED display panel with organic functional layer, manufacturing method thereof, and OLED display device
    Patent number: 12010865
    Abstract: An organic light-emitting diode (OLED) display panel, a manufacturing method thereof, and an OLED display device are provided. The OLED display panel disposes an organic functional layer under an encapsulation layer and makes the organic functional layer undergo visible changes when in contact with water and oxygen. Therefore, encapsulation effect can be tested by merely knowing the changes of the organic functional layer, and a test time is shorter. Meanwhile, a minimum distance between boundaries of the organic functional layer and the encapsulation layer is greater than a coating precision accuracy of the encapsulation layer, thereby ensuring the encapsulation effect.
