DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240206301 titled 'DISPLAY DEVICE
The present disclosure pertains to a display device that can enhance black characteristics by absorbing a whole wavelength band of visible light. This is achieved by incorporating a substrate with a light emission region and a non-light emission region, a light-emitting element with a first electrode, a light-emitting layer, and a second electrode, and a bank layer containing nano rods to define an opening part of the light emission region.
- The display device can implement black characteristics by absorbing a whole wavelength band of visible light.
- The substrate includes a light emission region and a non-light emission region.
- A light-emitting element is placed on the substrate, consisting of a first electrode, a light-emitting layer, and a second electrode.
- A bank layer with nano rods defines an opening part of the light emission region.
- The technology aims to improve the black visual sense of the display device.
- Potential Applications:**
This technology can be used in various display devices such as TVs, monitors, and smartphones to enhance the black levels and overall visual experience.
- Problems Solved:**
This technology addresses the issue of achieving true black colors on display devices by effectively absorbing visible light.
- Benefits:**
- Improved black characteristics on display devices - Enhanced visual experience for users - Better contrast and color accuracy
- Commercial Applications:**
This technology could be highly beneficial for manufacturers of display devices looking to improve the visual quality of their products and stay competitive in the market.
- Questions about the Technology:**
1. How does the incorporation of nano rods in the bank layer contribute to defining the opening part of the light emission region? 2. What specific advantages does the display device gain from absorbing a whole wavelength band of visible light for implementing black characteristics?
Original Abstract Submitted
aspects of the present disclosure relate to a display device and, more particularly, may provide a display device capable of implementing black characteristics by absorbing a whole wavelength band of visible light and improving a black visual sense by including a substrate including a light emission region and a non-light emission region, a light-emitting element disposed on the substrate and including a first electrode, a light-emitting layer, and a second electrode, and a bank layer defining an opening part of the light emission region and containing a nano rod.
