DISPLAY DEVICE, METHOD OF FABRICATING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18169160 titled 'DISPLAY DEVICE, METHOD OF FABRICATING THE SAME

Simplified Explanation

The patent application describes a display device and a method for fabricating it. The device includes a substrate with emission areas for displaying images, anode electrodes in the emission areas, a bank buffer layer covering the edges of the anode electrodes, and multi-layer structures with different metal materials and undercut structures.

  • The display device has emission areas for displaying images.
  • Anode electrodes are placed above the substrate in the emission areas.
  • A bank buffer layer covers the edges of the anode electrodes.
  • The device includes multi-layer structures with different metal materials and undercut structures.
  • A pixel-defining layer is placed above the first multi-layer.
  • A spacer is placed above the second multi-layer.

Potential applications of this technology:

  • This display device can be used in various electronic devices such as smartphones, tablets, and televisions.
  • It can be used in advertising displays, digital signage, and other visual communication systems.

Problems solved by this technology:

  • The bank buffer layer helps to protect the anode electrodes and prevent leakage of electrical signals.
  • The multi-layer structures with undercut structures provide better conductivity and stability to the display device.
  • The pixel-defining layer helps to define the individual pixels and improve image quality.

Benefits of this technology:

  • The display device provides improved image quality and resolution.
  • It offers better conductivity and stability, leading to a longer lifespan.
  • The fabrication method allows for efficient production of the display device.


Original Abstract Submitted

A display device and a method for fabricating the same are provided, the display device including a substrate including emission areas for displaying images, and a non-emission area between the emission areas, anode electrodes above the substrate and respectively in the emission areas, a bank buffer layer above the substrate in the non-emission area and covering edges of the anode electrodes, a first multi-layer above the bank buffer layer, including a stack of two or more different metal materials, and including an undercut structure, a pixel-defining layer above the first multi-layer, a second multi-layer above the pixel-defining layer, including a stack of two or more different metal materials, and including an undercut structure, and a spacer above the second multi-layer.
