DISPLAY APPARATUS, DISPLAY MODULE, ELECTRONIC DEVICE, AND METHOD OF MANUFACTURING DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18548186 titled 'DISPLAY APPARATUS, DISPLAY MODULE, ELECTRONIC DEVICE, AND METHOD OF MANUFACTURING DISPLAY APPARATUS

The abstract describes a high-definition and high-resolution display apparatus that involves the formation of multiple layers and sacrificial layers to create pixel electrodes and insulating films.

  • Conductive film, first layer, and first sacrificial layer are formed.
  • Second layer and second sacrificial layer are formed over the first sacrificial layer and conductive film.
  • Pixel electrodes are created by processing the layers to expose parts of the conductive film.
  • Insulating films are formed to cover various surfaces of the layers and sacrificial layers.
  • Sidewalls are formed by processing the insulating films to cover specific surfaces.
  • Common electrode is formed over the layers after removing the sacrificial layers.

Key Features and Innovation:

  • Formation of pixel electrodes by processing layers and sacrificial layers.
  • Use of insulating films to cover surfaces and create sidewalls.
  • Creation of a high-definition and high-resolution display apparatus.

Potential Applications:

  • High-quality display screens for electronic devices.
  • Advanced visual technologies for televisions and monitors.

Problems Solved:

  • Enhancing display quality and resolution.
  • Improving the efficiency of pixel electrode formation.

Benefits:

  • Clearer and sharper images on display screens.
  • Enhanced viewing experience for users.

Commercial Applications:

  • Manufacturing of high-end electronic devices with superior display capabilities.
  • Market implications in the consumer electronics industry.

Prior Art: Prior art related to this technology may include patents or research on high-definition display technologies, pixel electrode formation, and insulating film applications in display apparatus.

Frequently Updated Research: Research on advancements in display technology, materials science for display screens, and innovations in pixel electrode manufacturing processes may be relevant to this technology.

Questions about the Technology: 1. How does the formation of pixel electrodes contribute to the overall display quality? 2. What are the specific advantages of using sacrificial layers in the manufacturing process?


Original Abstract Submitted

A high-definition and high-resolution display apparatus is provided. A conductive film, a first layer, and a first sacrificial layer are formed. The first layer and the first sacrificial layer are processed to expose part of the conductive film. A second layer and a second sacrificial layer are formed over the first sacrificial layer and the conductive film. The second layer and the second sacrificial layer are processed to expose part of the conductive film. The conductive film is processed to form a first pixel electrode overlapping with the first sacrificial layer and a second pixel electrode overlapping with the second sacrificial layer. Two insulating films covering at least a side surface of the first pixel electrode, a side surface of the second pixel electrode, a side surface of the first layer, a side surface of the second layer, a side surface and a top surface of the first sacrificial layer, and a side surface and atop surface of the second sacrificial layer are formed. The two insulating films are processed to form a sidewall covering at least the side surface of the first pixel electrode and the side surface of the first layer. The first sacrificial layer and the second sacrificial layer are removed. A common electrode is formed over the first layer and the second layer.
