DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240215323 titled 'DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME
The abstract describes a display device with a complex bank structure that includes multiple layers with different materials, such as metal oxide and copper, to improve performance and functionality.
- The display device includes a first pixel electrode, inorganic insulating layer, bank structure, first light-emitting layer, and first common electrode.
- The bank structure consists of a first bank layer with metal oxide, a second bank layer with metal oxide, and a third bank layer with copper.
- The second bank layer has tips that protrude beyond the third bank layer on the sidewall of the first opening.
- The first and second bank layers have different tantalum (Ta) contents, enhancing the device's capabilities.
Potential Applications: - This technology can be used in high-resolution displays for smartphones, tablets, and TVs. - It can also be applied in augmented reality (AR) and virtual reality (VR) devices for enhanced visual experiences.
Problems Solved: - Improved performance and functionality of display devices. - Enhanced image quality and resolution. - Increased durability and longevity of the display.
Benefits: - Higher quality and resolution images. - Longer lifespan of display devices. - Enhanced user experience with sharper visuals.
Commercial Applications: - This technology can be utilized by display manufacturers to create cutting-edge products with superior performance and durability, catering to the growing demand for high-quality displays in various electronic devices.
Questions about the technology: 1. How does the use of different materials in the bank structure improve the performance of the display device? 2. What specific advantages does the inclusion of copper in the bank structure provide for the display technology?
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.
