DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18378606 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes a display panel, a backlight unit, and a light conversion sheet. The backlight unit consists of a substrate and light-emitting sections arranged on the substrate, with one or more light sources in each section. The light conversion sheet has partition walls and light conversion sections that correspond to the light-emitting sections. Each light conversion section contains first quantum dots emitting a first light and second quantum dots emitting a second light of a different color. The light sources provide light of a predetermined wavelength to the light conversion sheet.
- The display device includes a display panel, backlight unit, and light conversion sheet.
- The backlight unit consists of a substrate and light-emitting sections with one or more light sources.
- The light conversion sheet has partition walls and light conversion sections corresponding to the light-emitting sections.
- Each light conversion section contains first and second quantum dots emitting different colored lights.
- The light sources provide light of a predetermined wavelength to the light conversion sheet.
Potential applications of this technology:
- Display devices such as televisions, computer monitors, and mobile devices.
- Signage and advertising displays.
- Automotive displays and instrument clusters.
- Virtual reality and augmented reality headsets.
Problems solved by this technology:
- Improved color accuracy and vibrancy in display devices.
- Enhanced visibility and readability in various lighting conditions.
- Efficient light conversion for better energy efficiency.
- Reduction of color bleeding and cross-talk in displays.
Benefits of this technology:
- Enhanced visual experience with more accurate and vibrant colors.
- Improved readability and visibility in different lighting environments.
- Energy-efficient display devices with better light conversion.
- Reduced color bleeding and cross-talk for sharper images.
Original Abstract Submitted
A display device includes a display panel, a backlight unit, and a light conversion sheet between the display panel and the backlight unit. The backlight unit includes a substrate and light-emitting sections arranged on the substrate, one or more light sources are disposed in each of the light-emitting sections, the light conversion sheet includes first partition walls and light conversion sections arranged to correspond to the light-emitting sections, a first partition wall of the first partition walls is disposed between adjacent light conversion sections of the light conversion sections. Each of the light conversion sections includes first quantum dots emitting a first light and second quantum dots emitting a second light having a color different from a color of the first light, and the at least one light source provides light of a predetermined wavelength to the light conversion sheet.
