DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17692575 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes electrodes, insulating layers, wall patterns, light-emitting elements, and connecting electrodes. The first insulating layer is made of organic material, while the second insulating layer is made of inorganic material.
- The display device has a first electrode and a second electrode on a substrate, with a first insulating layer on top.
- Wall patterns are placed on the first insulating layer, overlapping the electrodes.
- A second insulating layer is added on top of the first insulating layer, covering the wall patterns.
- Light-emitting elements are directly placed on the second insulating layer, between the wall patterns.
- A bank layer surrounds the area with the light-emitting elements.
- A first connecting electrode is on the first electrode, making electrical contact with the light-emitting elements.
- A second connecting electrode is on the second electrode, also making electrical contact with the light-emitting elements.
Potential applications of this technology:
- Display devices for electronic devices such as smartphones, tablets, and televisions.
- Signage and advertising displays.
- Virtual reality and augmented reality headsets.
- Automotive displays and instrument clusters.
Problems solved by this technology:
- Provides a simplified and efficient structure for display devices.
- Enables the use of both organic and inorganic insulating materials for improved performance and durability.
- Allows for direct placement of light-emitting elements, reducing complexity and improving display quality.
Benefits of this technology:
- Enhanced display quality with improved electrical connections.
- Increased durability and lifespan of the display device.
- Simplified manufacturing process for display devices.
- Compatibility with various electronic devices and applications.
