DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18371370 titled 'DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME
The abstract describes a display device with a unique bank structure that includes multiple layers with specific compositions, such as MoTaOx and copper (Cu), to improve performance and efficiency.
- The display device includes a first pixel electrode, an inorganic insulating layer, a bank structure with a first opening, a first light-emitting layer, and a first common electrode.
- The bank structure consists of a first bank layer with MoTaOx, a second bank layer with MoTaOx and tips protruding beyond a third bank layer, and a third bank layer with copper (Cu).
- The second bank layer's tips on the sidewall of the first opening enhance the device's functionality.
- The first and second bank layers have different tantalum (Ta) contents, contributing to the device's overall performance.
Potential Applications: - This technology can be used in various display devices such as OLED screens, TVs, and monitors. - It can also be applied in flexible displays and wearable technology due to its unique bank structure design.
Problems Solved: - The technology addresses issues related to display device efficiency and performance. - It improves the overall quality and functionality of display screens.
Benefits: - Enhanced display performance and efficiency. - Improved image quality and brightness. - Potential for use in various electronic devices.
Commercial Applications: - This technology can be utilized by display manufacturers to create high-quality screens for consumer electronics. - It has the potential to impact the display industry by offering improved display solutions for a range of devices.
Questions about the technology: 1. How does the unique bank structure in this display device improve performance compared to traditional designs? 2. What are the specific advantages of using different Ta contents in the first and second bank layers in terms of display functionality and efficiency?
Original Abstract Submitted
A display device includes a first pixel electrode disposed on a substrate; an inorganic insulating layer disposed on the substrate; a bank structure disposed on the inorganic insulating layer and including a first opening, which overlap with the first pixel electrode; a first light-emitting layer disposed on the first pixel electrode; and a first common electrode disposed on the first light-emitting layer. The bank structure includes a first bank layer, which is disposed directly on the inorganic insulating layer and includes MoTaOx, a second bank layer, which is disposed on the first bank layer and includes MoTaOx, and a third bank layer, which is disposed between the first bank layer and the second bank layer and includes copper (Cu). The second bank layer includes tips, which protrude beyond the third bank layer, on a sidewall of the first opening, and the first and second bank layers include different Ta contents.
