DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240047616 titled 'DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME
Simplified Explanation
The present disclosure describes a display device that includes a substrate with multiple sub-pixels, each containing a light-emitting element. The device also includes a first connection electrode surrounding a first semiconductor layer located below the light-emitting element, and a second connection electrode in contact with the top surface of the light-emitting element. A first planarization layer with a smaller thickness than the first semiconductor layer is positioned between the first connection electrode and the second connection electrode, along with a second planarization layer between the first planarization layer and the second connection electrode.
- The display device includes a substrate with multiple sub-pixels and light-emitting elements, allowing for the creation of high-resolution displays.
- The first and second connection electrodes provide electrical connections to the light-emitting elements, ensuring proper functioning of the display.
- The first planarization layer helps to maintain a uniform surface and improve the performance of the display.
- The second planarization layer further enhances the surface uniformity and stability of the display.
Potential applications of this technology:
- High-resolution displays for smartphones, tablets, and other electronic devices.
- Displays for televisions and computer monitors.
- Virtual reality and augmented reality headsets.
- Automotive displays and infotainment systems.
Problems solved by this technology:
- Provides a solution for creating high-resolution displays with improved surface uniformity.
- Ensures proper electrical connections to the light-emitting elements, preventing malfunctioning pixels.
- Enhances the stability and performance of the display.
Benefits of this technology:
- Enables the production of high-quality displays with improved image clarity and resolution.
- Enhances the overall visual experience for users.
- Provides a more reliable and durable display technology.
- Allows for the development of thinner and lighter display devices.
Original Abstract Submitted
according to an aspect of the present disclosure, a display device includes a substrate in which a plurality of sub-pixels is defined, a light emitting element disposed on each of the plurality of sub-pixels, and a first connection electrode surrounding a first semiconductor layer disposed at a lower part of the light emitting element, a second connection electrode in contact with a top surface of the light emitting element, a first planarization layer disposed between the first connection electrode and the second connection electrode and having a smaller thickness than the first semiconductor layer of the light emitting element, and a second planarization layer disposed between the first planarization layer and the second connection electrode.
