DISPLAY DEVICE, DISPLAY MODULE, ELECTRONIC DEVICE, AND METHOD FOR MANUFACTURING DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240268152 titled 'DISPLAY DEVICE, DISPLAY MODULE, ELECTRONIC DEVICE, AND METHOD FOR MANUFACTURING DISPLAY DEVICE
The abstract describes a display device with high display quality, consisting of multiple light-emitting devices with specific layers and electrodes.
- Each light-emitting device includes a pixel electrode, light-emitting layer, functional layer, common layer, and common electrode.
- An insulating layer is positioned between the light-emitting layers of adjacent devices.
- The light-emitting layer and functional layer have island shapes within each device.
- The common layer and common electrode cover the insulating layer, with the end portion of the insulating layer having a tapered shape.
Potential Applications: - High-quality display screens for electronic devices - Advanced lighting systems for commercial and residential use
Problems Solved: - Improved display quality and efficiency - Enhanced durability and longevity of display devices
Benefits: - Crisp and vibrant display output - Energy-efficient operation - Long-lasting performance
Commercial Applications: Title: Advanced Display Technology for Enhanced Visual Experience This technology can be utilized in smartphones, tablets, TVs, monitors, and other electronic devices requiring high-quality displays. The market implications include increased demand for devices with superior visual capabilities.
Questions about the technology: 1. How does the island shape of the light-emitting layer and functional layer contribute to the display quality? 2. What are the advantages of having a tapered shape in the end portion of the insulating layer?
Original Abstract Submitted
a display device with high display quality is provided. the display device includes a plurality of light-emitting devices each including a pixel electrode, a light-emitting layer, a functional layer, a common layer, and a common electrode in this order and includes an insulating layer positioned between side surfaces of the light-emitting layers adjacent to each other. the light-emitting layer and the functional layer each having an island shape are provided in each light-emitting device, and the plurality of light-emitting devices share the common layer. the common layer and the common electrode are provided to cover the insulating layer. in a cross-sectional view, an end portion of the insulating layer has a tapered shape with a taper angle greater than 0� and less than 90�.
