LIGHT EMITTING DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240049516 titled 'LIGHT EMITTING DISPLAY DEVICE
Simplified Explanation
The abstract describes a light-emitting display device that includes various layers and components. These include a substrate, an anode, a pixel defining layer with an opening, an emission layer within the opening, a spacer with a step, a cathode formed in the emission layer and spacer, an encapsulation layer, and a light-blocking layer.
- The device has a substrate, which serves as a base for the other layers.
- An anode is present on the substrate, providing a positive electrode.
- A pixel defining layer with an opening overlaps the anode, helping to define individual pixels.
- An emission layer is located within the opening of the pixel defining layer, responsible for emitting light.
- A spacer is positioned on the pixel defining layer and has a step, providing a separation between layers.
- A cathode is formed in the emission layer, pixel defining layer, and spacer, serving as a negative electrode.
- An encapsulation layer is present on top of the cathode, protecting the layers beneath.
- A light-blocking layer is placed on the encapsulation layer, preventing unwanted light emission.
Potential applications of this technology:
- Display devices: The light-emitting display device described in the patent application can be used in various display applications, such as televisions, computer monitors, smartphones, and wearable devices.
- Lighting: The technology can also be applied in the field of lighting, where the light-emitting display device can be used to create energy-efficient and customizable lighting solutions.
