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

This abstract first appeared for US patent application 17942479 titled 'DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME

Simplified Explanation

The patent application describes a display device that includes multiple layers and electrodes to create pixel openings for displaying images.

  • The display device includes an insulating layer, a first lower electrode, a second lower electrode, a pixel definition layer, and a sacrificial layer.
  • The insulating layer is placed on a base layer.
  • The first and second lower electrodes are placed on the insulating layer and are spaced apart from each other.
  • The pixel definition layer is also placed on the insulating layer and has pixel openings that expose parts of the first and second lower electrodes.
  • The sacrificial layer is positioned between the pixel definition layer and the insulating layer and has sacrificial openings that correspond to the pixel openings.
  • The pixel definition layer overlaps the first side surface of the sacrificial layer in a plan view.

Potential applications of this technology:

  • Display devices such as televisions, computer monitors, and mobile phone screens.
  • Virtual reality and augmented reality headsets.
  • Automotive displays and instrument panels.
  • Wearable technology such as smartwatches and fitness trackers.

Problems solved by this technology:

  • Provides a simplified and efficient method for creating pixel openings in a display device.
  • Helps in improving the overall image quality and resolution of the display.
  • Reduces the complexity and cost of manufacturing display devices.

Benefits of this technology:

  • Enhanced display quality with clear and sharp images.
  • Improved manufacturing process with simplified steps.
  • Cost-effective production of display devices.
  • Enables the development of thinner and lighter display devices.


Original Abstract Submitted

A display device includes an insulating layer disposed on a base layer, a first lower electrode disposed on the insulating layer, a second lower electrode disposed on the insulating layer and spaced apart from the first lower electrode, a pixel definition layer disposed on the insulating layer and including pixel openings exposing at least a portion of each of the first lower electrode and the second lower electrode, and a sacrificial layer disposed between the pixel definition layer and the insulating layer and including a first side surface defining sacrificial openings corresponding to the pixel openings. The first side surface is overlapped by the pixel definition layer in a plan view.
