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

This abstract first appeared for US patent application 20240032404 titled 'DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME

Simplified Explanation

The abstract describes a display device that includes various layers and materials to improve its performance. Here is a simplified explanation of the patent application:

  • The display device consists of a substrate, an emission material layer, a pixel-defining film, a thin-film encapsulation layer, a low-refractive pattern layer, an etch stop layer, and a high-refractive planarization layer.
  • The emission material layer is responsible for emitting light and includes a pixel with a pixel electrode, an emissive layer, and a common electrode.
  • The pixel-defining film defines the boundaries of the pixel.
  • The thin-film encapsulation layer protects the emission material layer.
  • The low-refractive pattern layer overlaps the pixel-defining film and is placed on top of the thin-film encapsulation layer.
  • The etch stop layer, made of an inorganic material, is placed on the low-refractive pattern layer.
  • The high-refractive planarization layer, which includes a recess aligned with the low-refractive pattern layer, is formed on the etch stop layer.

Potential applications of this technology:

  • This display device can be used in various electronic devices, such as smartphones, tablets, televisions, and computer monitors.
  • It can also be used in augmented reality (AR) and virtual reality (VR) headsets to provide high-quality and immersive visual experiences.

Problems solved by this technology:

  • The display device addresses the issue of light leakage by using the thin-film encapsulation layer and the low-refractive pattern layer to prevent unwanted light from escaping the pixel area.
  • The etch stop layer helps in accurately aligning the high-refractive planarization layer with the low-refractive pattern layer, ensuring optimal performance of the display.

Benefits of this technology:

  • The display device offers improved image quality with reduced light leakage, resulting in better contrast and color accuracy.
  • The use of the thin-film encapsulation layer enhances the durability and lifespan of the display.
  • The high-refractive planarization layer helps in achieving a smoother and more uniform surface, enhancing the overall viewing experience.


Original Abstract Submitted
