DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17987622 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes a substrate, a partition wall, a light emitting element, a wavelength conversion layer, a light blocking member, a reflective member, and an optical pattern.
- The display device has a substrate and a partition wall that divides the substrate into different areas.
- A light emitting element is present in one of the areas and emits light in the thickness direction of the substrate.
- A wavelength conversion layer is placed on top of the light emitting element. It contains a base resin and wavelength conversion particles that convert the emitted light's wavelength.
- A light blocking member is positioned on the partition wall to prevent light leakage.
- A reflective member is located between the light blocking member and the partition wall to enhance light reflection.
- An optical pattern is formed on the wavelength conversion layer in the emission area, protruding in an upward direction away from the substrate.
Potential applications of this technology:
- Display devices such as televisions, computer monitors, and smartphones.
- Lighting systems for residential, commercial, and industrial purposes.
- Signage and advertising displays.
Problems solved by this technology:
- Efficient conversion of light emitted by the light emitting element to a desired wavelength.
- Prevention of light leakage and enhancement of light reflection for improved display quality.
- Creation of an optical pattern that enhances visual appeal and aesthetics.
Benefits of this technology:
- Improved color accuracy and vibrancy in display devices.
- Energy efficiency due to efficient wavelength conversion.
- Enhanced visual appeal and aesthetics with the optical pattern.
Original Abstract Submitted
A display device includes a substrate; a partition wall on the substrate; a light emitting element extends in a thickness direction of the substrate and is in an emission area of the substrate partitioned by the partition wall; a wavelength conversion layer on the light emitting element and includes a base resin and wavelength conversion particles dispersed in the base resin and being for converting a wavelength of light emitted from the light emitting element; a light blocking member on the partition wall; a reflective member between the light blocking member and the partition wall; and an optical pattern on the wavelength conversion layer in the emission area and having a shape protruding in an upward direction away from the substrate.
