ORGANIC LIGHT-EMITTING DIODE DISPLAY PANEL AND MANUFACTURING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240049565 titled 'ORGANIC LIGHT-EMITTING DIODE DISPLAY PANEL AND MANUFACTURING METHOD THEREOF

Simplified Explanation

The abstract describes an organic light-emitting diode (OLED) display panel and its manufacturing method. The OLED display panel consists of several layers including a substrate, a thin film transistor device, an auxiliary electrode, a passivation layer, a planarization layer, and a light-emitting device layer. The light-emitting device layer comprises an anode layer, a light-emitting functional layer, and a cathode layer. The panel also includes a first via hole above the auxiliary electrode, with a notch defined at the bottom of the inner sidewall of the via hole. The cathode layer extends through the via hole to connect with the auxiliary electrode.

  • The patent describes an OLED display panel with a unique structure that includes an auxiliary electrode and a first via hole with a notch.
  • The manufacturing method involves defining the first via hole and the notch in the panel.
  • The cathode layer extends through the via hole to connect with the auxiliary electrode, allowing for efficient electrical connection.

Potential applications of this technology:

  • OLED display panels can be used in various electronic devices such as smartphones, tablets, televisions, and wearable devices.
  • The unique structure of the panel can enhance the performance and efficiency of OLED displays, leading to better image quality and longer battery life.

Problems solved by this technology:

  • The notch at the bottom of the inner sidewall of the first via hole helps to prevent short circuits and improve the reliability of the OLED display panel.
  • The efficient electrical connection between the cathode layer and the auxiliary electrode ensures proper functioning of the light-emitting device layer.

Benefits of this technology:

  • The OLED display panel with the described structure and manufacturing method can provide improved image quality, brightness, and energy efficiency.
  • The notch and efficient electrical connection contribute to the reliability and longevity of the OLED display panel.
  • The technology can potentially lead to the development of thinner and lighter electronic devices with better display capabilities.
