DISPLAY DEVICE AND METHOD FOR FABRICATION THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18224610 titled 'DISPLAY DEVICE AND METHOD FOR FABRICATION THEREOF
Simplified Explanation
The display device described in the patent application includes first and second pixel electrodes, inorganic insulating layer, bank structure, light emitting layers, and common electrodes. The bank structure consists of first and second bank layers with different organic insulating materials, where the second bank layer has varying thicknesses and tips protruding more than the first bank layer. The first bank layer includes AlNiLaCu.
- Explanation of the patent:
- Display device with unique bank structure design for improved performance and efficiency.
- Potential applications of this technology:
- OLED displays, smartphones, tablets, TVs, monitors.
- Problems solved by this technology:
- Improved display quality, reduced power consumption, enhanced durability.
- Benefits of this technology:
- Higher resolution, better color accuracy, longer lifespan.
- Potential commercial applications of this technology:
- Consumer electronics, automotive displays, medical devices.
- Possible prior art:
- Similar bank structures in display devices with different materials and configurations.
- Unanswered Questions:
- How does the bank structure impact the overall display performance?
The bank structure plays a crucial role in defining the pixel layout and ensuring proper functioning of the display device. By controlling the deposition of organic insulating materials and varying the thickness of the second bank layer, the structure can influence factors such as light emission efficiency, color accuracy, and overall display quality.
- What are the specific advantages of using AlNiLaCu in the first bank layer?
AlNiLaCu is a unique material choice for the first bank layer in the display device. Its properties may contribute to improved adhesion, thermal stability, or electrical conductivity within the bank structure. Understanding the specific benefits of using AlNiLaCu can provide insights into the design and performance of the display technology.
Original Abstract Submitted
A display device includes first and second pixel electrodes on a substrate to be spaced apart from each other, an inorganic insulating layer on the substrate to partially cover the first pixel electrode and the second pixel electrode, a bank structure on the inorganic insulating layer, where first and second openings overlapping the first and second pixel electrodes are defined through the bank structure, first and second light emitting layers on the first and second pixel electrodes, and first and second common electrodes on the first and second light emitting layers. The bank structure includes first and second bank layers and including different organic insulating materials from each other, the second bank layer has different thicknesses depending on positions thereof, the second bank layer includes tips protruding more than side surfaces of the first bank layer defining the first and second openings, and the first bank layer includes AlNiLaCu.
