DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240121992 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device with improved bank structure design for better performance and durability.
- Anode electrodes are present in the display area.
- An inorganic insulating layer covers the anode electrodes.
- A bank structure with openings overlapping the anode electrodes is on the insulating layer.
- Light emitting layers are on the anode electrodes and in the openings.
- Cathode electrodes are on the light emitting layers and in the openings.
- A first power line is in the non-display area.
- A power connection electrode partially overlaps with the first power line and is between the first power line and the display area.
- The bank structure includes hole patterns on the power connection electrode in the non-display area, overlapping with the through portions.
- A first bank layer and a second bank layer are present, with the second bank layer having a tip protruding from a sidewall of the first bank layer.
Potential Applications
The technology can be applied in various display devices such as OLED screens, TVs, smartphones, and wearable devices.
Problems Solved
The innovation addresses issues related to bank structure design, improving the efficiency and longevity of display devices.
Benefits
