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 18580029 titled 'DISPLAY DEVICE, DISPLAY MODULE, ELECTRONIC DEVICE, AND METHOD FOR MANUFACTURING DISPLAY DEVICE

Simplified Explanation:

This patent application describes a display device with high display quality, consisting of two light-emitting devices with insulating layers in between.

• The display device includes a first light-emitting device and a second light-emitting device.
• Each light-emitting device has a pixel electrode, a light-emitting layer, and a common electrode.
• Insulating layers cover the side and part of the top surfaces of the light-emitting layers.
• The common electrode covers the insulating layers.
• The second insulating layer has a tapered shape at the end.
• The second insulating layer overlaps with the first insulating layer.
• The second insulating layer covers at least part of the side surface of the first insulating layer.

Key Features and Innovation:

• High display quality with two light-emitting devices.
• Insulating layers for protection and insulation.
• Common electrodes for efficient operation.
• Tapered shape of the second insulating layer for improved design.
• Overlapping insulating layers for enhanced performance.

Potential Applications:

• Consumer electronics such as smartphones, tablets, and TVs.
• Medical devices for displays in healthcare settings.
• Automotive displays for navigation and entertainment systems.

Problems Solved:

• Improved display quality.
• Enhanced durability and protection.
• Efficient operation and performance.

Benefits:

• High-quality display output.
• Increased device longevity.
• Improved user experience.

Commercial Applications:

Display technology for consumer electronics, medical devices, and automotive applications.

Questions about Display Technology: 1. How does the overlapping insulating layers contribute to the performance of the display device? 2. What are the specific advantages of the tapered shape of the second insulating layer in this display technology?

Original Abstract Submitted

A display device with high display quality is provided. The display device includes a first light-emitting device, a second light-emitting device, a first insulating layer, and a second insulating layer; the first light-emitting device includes a first pixel electrode, a first light-emitting layer over the first pixel electrode, and a common electrode over the first light-emitting layer; the second light-emitting device includes a second pixel electrode, a second light-emitting layer over the second pixel electrode, and the common electrode over the second light-emitting layer; the first insulating layer covers a side surface and part of a top surface of the first light-emitting layer and a side surface and part of a top surface of the second light-emitting layer; the second insulating layer overlaps with the side surface and the part of the top surface of the first light-emitting layer and the side surface and the part of the top surface of the second light-emitting layer with the first insulating layer therebetween; the common electrode covers the second insulating layer; in a cross-sectional view, an end portion of the second insulating layer has a tapered shape with a taper angle less than 90°; and the second insulating layer covers at least part of a side surface of the first insulating layer.
