OLED DISPLAY SUBSTRATE, MANUFACTURING METHOD THEREOF AND DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17425563 titled 'OLED DISPLAY SUBSTRATE, MANUFACTURING METHOD THEREOF AND DISPLAY DEVICE
Simplified Explanation
The present disclosure describes a manufacturing method for an OLED display substrate and a display device. The method involves several steps, including forming a driving circuitry layer and a first electrode on a base substrate, applying a protection layer over the first electrode, creating auxiliary electrode structures with notches to expose a conductive portion, removing part of the protection layer to expose the first electrode, forming a light-emitting layer with interruptions at the notches to expose the side surface of the auxiliary electrode structures, and finally, forming a second electrode that is electrically connected to the conductive portion on the side surface of the auxiliary electrode structures.
- The manufacturing method involves forming a driving circuitry layer and a first electrode on a base substrate.
- A protection layer is applied to cover the first electrode.
- Auxiliary electrode structures are created with notches to expose a conductive portion.
- Part of the protection layer is removed to expose the first electrode.
- A light-emitting layer is formed with interruptions at the notches to expose the side surface of the auxiliary electrode structures.
- A second electrode is formed and electrically connected to the conductive portion on the side surface of the auxiliary electrode structures.
Potential applications of this technology:
- OLED display panels for various electronic devices such as smartphones, tablets, televisions, and wearable devices.
- Flexible OLED displays for curved or foldable devices.
- High-resolution OLED displays for virtual reality (VR) or augmented reality (AR) headsets.
Problems solved by this technology:
- Simplifies the manufacturing process of OLED display substrates by integrating multiple steps into a single method.
- Provides a protective layer for the first electrode, ensuring its integrity during subsequent manufacturing steps.
- Allows for precise exposure of the conductive portion of the auxiliary electrode structures, enabling efficient electrical coupling with the second electrode.
Benefits of this technology:
- Streamlines the production of OLED display substrates, reducing manufacturing time and costs.
- Enhances the durability and reliability of the display by protecting the first electrode.
- Improves the electrical connection between the auxiliary electrode structures and the second electrode, leading to better overall performance of the OLED display.
