DISPLAY APPARATUS, DISPLAY MODULE, ELECTRONIC DEVICE, AND METHOD FOR FABRICATING DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18555903 titled 'DISPLAY APPARATUS, DISPLAY MODULE, ELECTRONIC DEVICE, AND METHOD FOR FABRICATING DISPLAY APPARATUS

Simplified Explanation: The patent application describes a display apparatus with two light-emitting devices and an inorganic insulating layer to improve reliability.

  • The display apparatus includes a first light-emitting device with a first pixel electrode, a first light-emitting layer, and a common electrode.
  • A second light-emitting device is also present, consisting of a second pixel electrode, a second light-emitting layer, and the common electrode.
  • An inorganic insulating layer covers the side surfaces of the pixel electrodes and light-emitting layers to enhance performance.
  • The inorganic insulating layer has low hydrogen and carbon concentrations for optimal functionality.

Key Features and Innovation:

  • Dual light-emitting devices for improved display quality.
  • Inorganic insulating layer for enhanced reliability.
  • Low hydrogen and carbon concentrations in the insulating layer for optimal performance.

Potential Applications: The technology can be applied in:

  • OLED displays
  • Electronic devices
  • Automotive displays

Problems Solved:

  • Enhances display reliability
  • Improves display quality
  • Reduces the risk of malfunctions

Benefits:

  • Increased display longevity
  • Enhanced visual performance
  • Reduced maintenance needs

Commercial Applications: Potential commercial applications include:

  • Consumer electronics
  • Automotive industry
  • Display manufacturing companies

Questions about Display Apparatus: 1. How does the inorganic insulating layer improve the reliability of the display apparatus? 2. What are the specific benefits of having dual light-emitting devices in the display apparatus?


Original Abstract Submitted

A highly reliable display apparatus is provided. The display apparatus includes a first light-emitting device, a second light-emitting device, and an inorganic insulating layer. The first light-emitting device includes a first pixel electrode, a first light-emitting layer over the first pixel electrode, and a common electrode over the first light-emitting layer. The second light-emitting device includes a second pixel electrode, a second light-emitting layer over the second pixel electrode, and the common electrode over the second light-emitting layer. The inorganic insulating layer covers side surfaces of the first pixel electrode, the second pixel electrode, the first light-emitting layer, and the second light-emitting layer. The hydrogen concentration and the carbon concentration in the inorganic insulating layer are each preferably sufficiently low.
