DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240224614 titled 'DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME
The display device described in the patent application includes multiple layers that work together to improve the functionality and performance of the device.
- Interlayer insulating layer exposes an auxiliary line
- Protection layer is placed on the interlayer insulating layer but removed from the area above the auxiliary line
- Pixel defining layer covers the protection layer and interlayer insulating layer, with a portion protruding to define an undercut area
- Light emitting layer covers the pixel defining layer, exposing the auxiliary line in the undercut area
- Cathode electrode is placed on the light emitting layer, contacting the auxiliary line in the undercut area
Potential Applications: - This technology can be used in various display devices such as OLED screens, LED displays, and more. - It can enhance the performance and durability of electronic devices with display screens.
Problems Solved: - Improved functionality and performance of display devices - Enhanced protection for the components within the display device
Benefits: - Better display quality - Increased durability and longevity of display devices - Enhanced user experience with electronic devices
Commercial Applications: - This technology can be applied in the manufacturing of smartphones, tablets, TVs, monitors, and other electronic devices with display screens.
Questions about the technology: 1. How does the pixel defining layer contribute to the overall functionality of the display device? 2. What are the specific advantages of the undercut area in the pixel defining layer?
Original Abstract Submitted
a display device includes an interlayer insulating layer exposing an auxiliary line, a protection layer disposed on the interlayer insulating layer and removed from an area above the auxiliary line, a pixel defining layer disposed on the protection layer and including a first portion covering one side surfaces of the protection layer and the interlayer insulating layer and a second portion protruding toward the first portion beyond an edge of other side surfaces of the interlayer insulating layer and the protection layer and defining a undercut area, a light emitting layer covering the first portion of the pixel defining layer and exposing the auxiliary line in the undercut area, and a cathode electrode disposed on the light emitting layer and contacting the auxiliary line in the undercut area.
