DISPLAY DEVICE AND METHOD FOR MANUFACTURING DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18750319 titled 'DISPLAY DEVICE AND METHOD FOR MANUFACTURING DISPLAY DEVICE
Simplified Explanation: The patent application describes a display device with specific layers and regions that control the dopant concentration of a guest material in different areas of the device.
- The display device includes a lower electrode, a second insulating layer with an opening, an organic layer with a light-emitting layer and a functional layer, and an upper electrode.
- The functional layer has a first region between the lower electrode and the light-emitting layer, and a second region above the second insulating layer with a lower dopant concentration.
- The dopant concentration of the guest material in the second region is lower than in the first region.
Key Features and Innovation:
- Specific layer structure with different regions for controlling dopant concentration.
- Lower dopant concentration in the second region for improved device performance.
- Precise placement of the organic and functional layers for optimal functionality.
Potential Applications:
- OLED displays
- Lighting applications
- Electronic signage
Problems Solved:
- Control of dopant concentration in specific regions
- Enhanced device performance and efficiency
Benefits:
- Improved display quality
- Energy efficiency
- Extended device lifespan

Questions about Display Device Technology: 1. How does the dopant concentration affect the performance of the display device? 2. What are the specific advantages of having different dopant concentrations in different regions of the device?
Frequently Updated Research: Ongoing research in OLED technology and display devices may provide further insights into optimizing dopant concentrations for improved performance and efficiency.
Original Abstract Submitted
According to one embodiment, a display device includes a lower electrode, a second insulating layer including an opening overlapping the lower electrode, an organic layer including a light-emitting layer and a functional layer, disposed in the opening and covering the lower electrode and an upper electrode covering the organic layer. The functional layer includes a first region located between the lower electrode and the light-emitting layer and a second region including an end surface located directly above the second insulating layer. A dopant concentration of a guest material in the second region is lower than the dopant concentration of the guest material in the first region.
