DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240302928 titled 'DISPLAY DEVICE
The display device described in the patent application includes a substrate with emission and non-emission areas, a light-emitting element on the substrate, a thin-film encapsulation layer overlapping with the emission and non-emission areas, and a touch sensor layer on top.
Key Features and Innovation:
- The touch sensor layer comprises a first conductive layer, a touch insulating layer, and a second conductive layer.
- The touch insulating layer overlaps with the non-emission area and has a unique structure with a first surface facing the encapsulation layer, a second surface with a greater width, and an inclined surface connecting the two.
- The second conductive layer covers the second surface and the inclined surface, providing touch sensitivity.
Potential Applications: This technology can be used in various touch-sensitive display devices, such as smartphones, tablets, and interactive kiosks.
Problems Solved: This innovation addresses the need for touch sensitivity in display devices while maintaining efficient light emission and encapsulation.
Benefits:
- Improved touch sensitivity and accuracy on display devices.
- Enhanced durability and protection of the light-emitting element.
- Streamlined manufacturing process for touch-sensitive displays.
Commercial Applications: This technology can be applied in the consumer electronics industry for the development of advanced touch-sensitive displays, potentially increasing user interaction and device functionality.
Questions about the technology: 1. How does the unique structure of the touch insulating layer improve touch sensitivity? 2. What are the potential cost implications of implementing this technology in display devices?
Frequently Updated Research: Stay updated on advancements in touch sensor technology and display device innovations to enhance the functionality and performance of future devices.
Original Abstract Submitted
a display device includes a substrate comprising emission and non-emission areas. a light-emitting element overlaps the emission area and is on the substrate. a thin-film encapsulation layer overlaps with the emission and non-emission areas and is on the light-emitting element. a touch sensor layer is on the thin-film encapsulation layer. the touch sensor layer comprises a first conductive layer on the thin-film encapsulation layer. a touch insulating layer is on the first conductive layer. a second conductive layer is on the touch insulating layer. the touch insulating layer overlaps with the non-emission area and comprises a first surface facing the thin-film encapsulation layer. a second surface is opposite to the first surface and has a width in a first direction greater than that of the first surface. an inclined surface connects the first and second surfaces. the second conductive layer covers the second surface and the inclined surface.
