NANOWIRE LED, DISPLAY MODULE INCLUDING THE NANOWIRE LED, AND METHOD FOR MANUFACTURING THE DISPLAY MODULE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18094112 titled 'NANOWIRE LED, DISPLAY MODULE INCLUDING THE NANOWIRE LED, AND METHOD FOR MANUFACTURING THE DISPLAY MODULE
Simplified Explanation
The abstract describes a nanowire LED display module and a method for manufacturing it. Here are the key points:
- The method starts by forming a template layer with a magnetic layer on a silicon substrate.
- A plurality of nanowire LEDs are grown on the template layer.
- Ultrasonic waves are used to separate the nanowire LEDs from the template layer.
- The nanowire LEDs are then aligned to have a specific directivity and formed into unit cells.
- These unit cells are transferred onto a unit substrate to create unit pixels.
- The unit pixels are arranged on a thin film transistor (TFT) substrate using fluidic self-assembly.
- Finally, the unit pixels are bonded to an electrode of the TFT substrate.
Potential applications of this technology:
- High-resolution displays for electronic devices such as smartphones, tablets, and televisions.
- Flexible and bendable displays for wearable devices and curved screens.
- Transparent displays for augmented reality (AR) and heads-up displays (HUD).
- Energy-efficient displays for reducing power consumption in electronic devices.
Problems solved by this technology:
- Simplified manufacturing process for nanowire LED display modules.
- Improved alignment and directivity of nanowire LEDs for better display quality.
- Efficient transfer and arrangement of unit cells onto a substrate.
- Enhanced bonding between unit pixels and electrodes for reliable performance.
Benefits of this technology:
- Higher resolution and pixel density for sharper and more detailed images.
- Flexibility and bendability for versatile display designs.
- Transparency for seamless integration into various applications.
- Energy efficiency for longer battery life in portable devices.
