DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18688851 titled 'DISPLAY APPARATUS

The abstract describes a display apparatus with high display quality, including a transistor, insulating layers, a plug, and a light-emitting device.

  • The display apparatus features a transistor, insulating layers, a plug, and a light-emitting device.
  • The top surface of the first insulating layer is level with the plug, ensuring smoothness.
  • The light-emitting device consists of a pixel electrode and an EL layer for illumination.
  • The second insulating layer includes a region that overlaps with the light-emitting region of the device.
  • The pixel electrode is in contact with the first region of the second insulating layer.
  • The pixel electrode also overlaps with and is electrically connected to the plug.

Potential Applications: - High-quality displays for consumer electronics - Advanced display technology for medical imaging devices - Enhanced visual output for automotive displays

Problems Solved: - Improved display quality and performance - Enhanced durability and longevity of display components - Better color accuracy and brightness in display screens

Benefits: - Crisp and clear visual output - Long-lasting display performance - Energy-efficient technology for reduced power consumption

Commercial Applications: Title: Advanced Display Technology for Enhanced Visual Experiences This technology can be utilized in smartphones, tablets, TVs, and other electronic devices, enhancing the user experience and attracting consumers looking for high-quality displays.

Questions about the technology: 1. How does this display apparatus improve visual quality compared to traditional displays? 2. What are the potential cost implications of implementing this technology in consumer electronics?


Original Abstract Submitted

A display apparatus with high display quality is provided. The display apparatus includes a transistor, a first insulating layer over the transistor, a plug electrically connected to the transistor, a second insulating layer over the first insulating layer, and a light-emitting device over the second insulating layer; a top surface of the first insulating layer includes a region that is substantially level with the plug; the light-emitting device includes a pixel electrode and an EL layer over the pixel electrode; the second insulating layer includes a first region interposed between the first insulating layer and a second pixel electrode; the first region overlaps with a light-emitting region of the light-emitting device; the pixel electrode is in contact with a top surface of the first region; in a top view, the second insulating layer includes a first end portion overlapping with the plug; at least part of the first end portion is covered with the pixel electrode; at least part of a side surface of the pixel electrode is covered with the EL layer; and the pixel electrode includes a region overlapping with a top surface of the plug and electrically connected to the plug.
