LIGHT EMITTING DISPLAY DEVICE AND METHOD OF MANUFACTURING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240260323 titled 'LIGHT EMITTING DISPLAY DEVICE AND METHOD OF MANUFACTURING SAME
The abstract describes a light-emitting display device with multiple anodes, an auxiliary electrode, a bank, a bank protection pattern, an interlayer, and a cathode connected to the auxiliary electrode within the bank hole.
- The device includes spaced-apart anodes and an auxiliary electrode to ensure uniform voltage application across the display area.
- A bank exposes the light-emitting parts of the anodes and protects the interlayer from damage due to outgassing.
- The cathode is connected to the auxiliary electrode within the bank hole for efficient operation.
- The bank protection pattern surrounds the bank hole to prevent damage to the interlayer.
- The connection portion between the auxiliary electrode and the cathode in the active area prevents luminance non-uniformity.
Potential Applications: - This technology can be used in various display devices such as TVs, monitors, and smartphones. - It can also be applied in signage, automotive displays, and wearable technology.
Problems Solved: - Ensures uniform voltage application across the display area. - Prevents luminance non-uniformity. - Protects the interlayer from damage due to outgassing.
Benefits: - Improved display quality. - Enhanced durability and longevity of the display device. - Consistent luminance levels across the display area.
Commercial Applications: Title: Advanced Light-Emitting Display Technology for Enhanced Visual Experience This technology can be commercially used in the manufacturing of high-quality display devices for consumer electronics, automotive displays, and signage. The improved performance and durability of the displays can lead to increased customer satisfaction and market competitiveness.
Prior Art: Further research can be conducted in the field of display technology, specifically focusing on advancements in light-emitting display devices and methods to improve luminance uniformity.
Frequently Updated Research: Researchers are continually exploring ways to enhance the efficiency and performance of light-emitting display devices, including advancements in materials, design, and manufacturing processes.
Questions about Light-Emitting Display Devices: 1. How does the auxiliary electrode contribute to ensuring uniform voltage application in the display area? The auxiliary electrode helps distribute voltage evenly across the display area, preventing luminance non-uniformity.
2. What role does the bank protection pattern play in protecting the interlayer in the display device? The bank protection pattern surrounds the bank hole, shielding the interlayer from damage caused by outgassing and ensuring the longevity of the device.
Original Abstract Submitted
a light emitting display device includes a plurality of anodes spaced apart from each other on a substrate, an auxiliary electrode between adjacent anodes among the plurality of anodes, a bank exposing light emitting parts of the plurality of anodes and having a bank hole exposing a part of the auxiliary electrode, a bank protection pattern on a bank side surface surrounding the bank hole and on the bank around the bank hole, an interlayer on the light emitting parts and the bank, and a cathode connected to the auxiliary electrode within the bank hole. a connection portion between the auxiliary electrode and the cathode is provided in an active area to apply a uniform voltage to the entire display area and prevent luminance non-uniformity. by the bank protection pattern, the interlayer is prevented from being damaged due to outgassing from an exposure of the bank.
