DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240224669 titled 'DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME
The abstract describes a display device with an auxiliary power line, inorganic insulating layers, a pixel defining layer, and a common electrode.
- The auxiliary power line is located in the display area on a substrate.
- The first inorganic insulating layer is above the auxiliary power line and has an opening to the upper surface of the power line.
- The second inorganic insulating layer is on top of the first layer and has an opening connected to the first opening.
- The pixel defining layer is on the second insulating layer and has a pixel contact hole connected to the openings.
- The pixel defining layer includes a protrusion at the end towards the center of the pixel contact hole.
- The common electrode is on the pixel defining layer and connected to the auxiliary power line.
Potential Applications: - This technology can be used in various display devices such as LCD screens and OLED displays. - It can also be applied in touchscreens and electronic signage.
Problems Solved: - Provides a reliable and efficient way to power and control pixels in a display device. - Ensures proper insulation and connection between components.
Benefits: - Improved display performance and longevity. - Enhanced energy efficiency in display devices. - Simplified manufacturing process for display panels.
Commercial Applications: - This technology can be utilized in the production of smartphones, tablets, TVs, and computer monitors. - It can also find applications in automotive displays and wearable technology.
Questions about the Technology: 1. How does the protrusion in the pixel defining layer contribute to the functionality of the display device? 2. What are the advantages of using inorganic insulating layers in this display technology?
Original Abstract Submitted
a display device is disclosed that includes an auxiliary power line, a first inorganic insulating layer, a second inorganic insulating layer, a pixel defining layer, and a common electrode. the auxiliary power line is disposed in a display area on a substrate. the first inorganic insulating layer is disposed on the auxiliary power line and defines a first opening extending to at least part of an upper surface of the auxiliary power line. the second inorganic insulating layer is disposed on the first inorganic insulating layer and defines a second opening connected to the first opening. the pixel defining layer is disposed on the second inorganic insulating layer and defines a pixel contact hole connected to the first and second openings. an end of the pixel defining layer includes a protrusion protruding toward a center of the pixel contact hole. the common electrode disposed on the pixel defining layer and electrically connected to the auxiliary power line.
