DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18223854 titled 'DISPLAY APPARATUS
Simplified Explanation
The patent application describes a display apparatus that includes a circuit board with a driving circuit and a pixel array. The pixel array consists of pixels, each of which has multiple sub-pixels. The pixel array also includes a semiconductor stack, a conductive partition structure, and wavelength conversion portions.
- The semiconductor stack is made up of LED cells that form the sub-pixels. Each LED cell includes an active layer and a second conductivity-type semiconductor layer.
- The conductive partition structure is placed between the sub-pixel spaces and overlaps the LED cells on the semiconductor stack. It serves as a first electrode.
- The wavelength conversion portions are located on the sub-pixel spaces.
Potential applications of this technology:
- High-resolution displays: The use of multiple sub-pixels allows for increased pixel density and improved image quality.
- Color accuracy: The wavelength conversion portions can enhance the color reproduction capabilities of the display.
- Energy efficiency: The LED cells and conductive partition structure can help optimize power consumption.
Problems solved by this technology:
- Improved image quality: The use of sub-pixels and wavelength conversion portions can result in sharper and more vibrant images.
- Enhanced color reproduction: The wavelength conversion portions enable accurate and vivid color representation.
- Power optimization: The design of the LED cells and conductive partition structure helps reduce energy consumption.
Benefits of this technology:
- Higher resolution and image quality: The display apparatus can provide sharper and more detailed visuals.
- Accurate and vibrant colors: The wavelength conversion portions contribute to improved color reproduction.
- Energy-efficient operation: The design features of the LED cells and conductive partition structure help conserve power.
