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

This abstract first appeared for US patent application 20240032378 titled 'DISPLAY DEVICE AND A MANUFACTURING METHOD OF THE SAME

Simplified Explanation

The abstract describes a display device with a display panel and an input sensing unit. The display panel has a display region and a non-display region, while the input sensing unit has an active region and a peripheral region. The display panel includes a base layer, a circuit element layer with insulating layers and a voltage line, and a display element layer with a pixel defining film and a light-emitting element. The light-emitting element has a first electrode, a second electrode, and an organic layer between them. The organic layer overlaps both the display region and the non-display region, with a first opening formed in the second portion to connect the second electrode and the voltage line.

  • The display device has a display panel with a display region and a non-display region.
  • An input sensing unit is present on the display panel, with an active region and a peripheral region.
  • The display panel includes a base layer, a circuit element layer, and a display element layer.
  • The circuit element layer has insulating layers and a voltage line.
  • The display element layer includes a pixel defining film and a light-emitting element.
  • The light-emitting element consists of a first electrode, a second electrode, and an organic layer.
  • The organic layer overlaps both the display region and the non-display region.
  • A first opening is formed in the second portion of the organic layer.
  • The second electrode and the voltage line are electrically connected through the first opening.

Potential Applications:

  • This display device can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
  • It can provide enhanced visual experiences with its display panel and input sensing capabilities.

Problems Solved:

  • The display device solves the problem of integrating an input sensing unit into a display panel, allowing for a more compact and efficient design.
  • It also addresses the challenge of connecting the second electrode and the voltage line in a seamless and reliable manner.

Benefits:

  • The display device offers a larger display region for content viewing and a separate non-display region for input sensing.
  • The integration of the input sensing unit eliminates the need for additional external input devices.
  • The electrical connection between the second electrode and the voltage line through the first opening ensures proper functioning of the light-emitting element.


Original Abstract Submitted
