DISPLAY DEVICE AND ELECTRONIC DEVICE HAVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240040890 titled 'DISPLAY DEVICE AND ELECTRONIC DEVICE HAVING THE SAME
Simplified Explanation
The patent application describes a display device that includes pixel electrodes, a pixel defining layer, an encapsulation layer, a sensing electrode, a first insulating layer, and a second insulating layer.
- The pixel electrodes are placed on a substrate.
- The pixel defining layer is positioned on the pixel electrodes and has pixel openings that overlap with the pixel electrodes.
- The encapsulation layer is placed on the pixel electrodes and the pixel defining layer.
- The sensing electrode is positioned on the encapsulation layer.
- The first insulating layer is placed on the sensing electrode and has openings that overlap with the pixel openings.
- The second insulating layer is positioned on the first insulating layer and has a higher refractive index than the first insulating layer.
- The openings of the first insulating layer include protruding extensions, and each opening has at least eight protruding directions.
Potential applications of this technology:
- Display devices: This technology can be used in various display devices such as televisions, smartphones, tablets, and computer monitors.
- Virtual reality (VR) and augmented reality (AR): The display device can be used in VR and AR headsets to provide high-quality visuals and immersive experiences.
- Wearable devices: This technology can be applied in smartwatches, fitness trackers, and other wearable devices that require compact and efficient display systems.
Problems solved by this technology:
- Improved image quality: The use of the second insulating layer with a higher refractive index helps enhance the display device's optical properties, resulting in improved image quality and clarity.
- Reduction of cross-talk: The pixel defining layer and the first insulating layer with overlapping openings help reduce cross-talk between adjacent pixels, leading to sharper and more accurate images.
- Enhanced durability: The encapsulation layer protects the pixel electrodes and other components, increasing the device's durability and resistance to external factors.
Benefits of this technology:
- Higher resolution: The pixel electrodes and the pixel defining layer with overlapping openings allow for higher pixel density, resulting in higher resolution displays.
- Improved color reproduction: The use of the second insulating layer with a higher refractive index helps improve color reproduction and accuracy.
- Enhanced viewing angles: The reduction of cross-talk and improved optical properties contribute to wider viewing angles, allowing for better visibility from different perspectives.
