DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18498232 titled 'DISPLAY DEVICE
The display device described in the patent application includes anode electrodes, an inorganic insulating layer, a bank structure, light emitting layers, cathode electrodes, a first power line, and a conductive layer with an oxide semiconductor.
- Anode electrodes are present in the display area.
- An inorganic insulating layer covers the display area and partially overlaps the anode electrodes.
- A bank structure is located on the inorganic insulating layer, with openings that align with the anode electrodes.
- Light emitting layers are situated on the anode electrodes and within the openings.
- Cathode electrodes are placed on the light emitting layers and within the openings.
- A first power line is positioned in a non-display area.
- A conductive layer, including an oxide semiconductor, is present, with a portion in the non-display area between the first power line and the display area.
- The bank structure on the conductive layer in the non-display area includes first and second bank layers made of different metal materials.
Potential Applications: - This technology can be used in the manufacturing of high-quality display devices such as OLED screens.

Original Abstract Submitted
A display device includes anode electrodes in a display area, an inorganic insulating layer in the display area and partially on the anode electrode, a bank structure on the inorganic insulating layer, with openings overlapping the anode electrodes, light emitting layers on the anode electrodes and in the openings, cathode electrodes on the light emitting layers and in the openings, a first power line in a non-display area, and a conductive layer including an oxide semiconductor. A portion of the conductive layer in the non-display area is between the first power line and the display area. The bank structure is on the conductive layer in the non-display area with hole patterns defined further through the conductive layer, the bank structure includes first and second bank layers including different metal materials, respectively, and a portion of the first bank layer is directly on the conductive layer in the non-display area.
