DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240224707 titled 'DISPLAY DEVICE
The abstract describes a display device with a sub-electrode layer in the non-display area and banks on the planarization layer in the display area, exposing part of the anode.
- Sub-electrode layer on the substrate in the non-display area
- Banks on the planarization layer in the display area
- Banks have opening portions exposing part of the sub-electrode layer
- Sub-electrode layer has oxygen vacancies where it overlaps with the bank opening portions
- Improves reliability by preventing pixel degradation caused by oxygen
Potential Applications: - Display devices in various electronic products - Touchscreen panels - Monitors and TVs
Problems Solved: - Degradation of pixels due to oxygen exposure - Reliability issues in display devices
Benefits: - Enhanced display device reliability - Improved pixel performance - Extended lifespan of display screens
Commercial Applications: Title: Advanced Display Devices for Enhanced Reliability This technology can be used in various electronic devices such as smartphones, tablets, laptops, and televisions, improving the overall performance and longevity of display screens. The market implications include increased consumer trust in the durability of electronic products.
Prior Art: Prior research in display technology focusing on improving pixel performance and reliability.
Frequently Updated Research: Ongoing research in display device technology to further enhance reliability and performance.
Questions about Display Device Technology: 1. How does the presence of oxygen vacancies in the sub-electrode layer contribute to the reliability of the display device? - The oxygen vacancies in the sub-electrode layer help prevent degradation of pixels by reducing the impact of oxygen exposure, thus improving the overall reliability of the display device.
2. What are the key differences between the banks in the display area and the non-display area in the display device? - The banks in the display area are on the planarization layer and expose part of the anode, while the banks in the non-display area are on the sub-electrode layer and have opening portions exposing part of the sub-electrode layer.
Original Abstract Submitted
a display device includes a sub-electrode layer disposed on the substrate while corresponding to at least a part of the non-display area; and banks disposed on the planarization layer in the display area so as to expose at least a part of the anode and disposed on the sub-electrode layer in the non-display area, in which the bank includes a plurality of bank opening portions disposed in the non-display area so as to expose at least a part of the sub-electrode layer, and in which the sub-electrode layer includes oxygen vacancies in an area in which the sub-electrode layer overlaps the plurality of bank opening portions. therefore, the display device according to the present disclosure, it is possible to provide the display device capable of implementing excellent reliability by suppressing degradation of the pixel caused by oxygen.
