DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240040917 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes light emitting elements, a color filter layer, a light control pattern, and light conversion patterns using quantum dots.
- The display device has light emitting elements that emit a source light.
- The color filter layer is arranged in a first direction and includes first to third pixel areas and a light blocking area surrounding them.
- The light control pattern overlaps the second pixel area and defines first and second openings through the pattern and the light blocking area.
- The first opening overlaps the first pixel area and a portion of the light blocking area.
- The second opening overlaps the third pixel area and another portion of the light blocking area.
- A first light conversion pattern is disposed in the first opening and includes a first quantum dot.
- A second light conversion pattern is disposed in the second opening and includes a second quantum dot.
Potential applications of this technology:
- High-resolution displays: The use of light emitting elements and quantum dots can enhance the color accuracy and brightness of displays, making them suitable for high-resolution applications such as televisions and monitors.
- Virtual reality and augmented reality: The improved color reproduction and light control provided by the display device can enhance the immersive experience in virtual reality and augmented reality applications.
- Medical imaging: The accurate color representation and brightness control can be beneficial in medical imaging devices, allowing for better visualization and analysis of medical images.
Problems solved by this technology:
- Color accuracy: The use of quantum dots in the light conversion patterns helps to achieve more accurate and vibrant colors on the display, addressing the problem of color reproduction in traditional displays.
- Light control: The light control pattern and the openings defined through it allow for precise control of the light emitted by the display device, reducing light leakage and improving contrast ratio.
Benefits of this technology:
- Enhanced color reproduction: The incorporation of quantum dots in the light conversion patterns improves the color accuracy and vibrancy of the display, resulting in a more visually appealing viewing experience.
- Improved contrast ratio: The light control pattern and the defined openings help to minimize light leakage and enhance the contrast ratio of the display, leading to sharper and more detailed images.
- Energy efficiency: By controlling the light emitted by the display device, energy consumption can be optimized, resulting in improved energy efficiency compared to traditional displays.
