DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18509472 titled 'DISPLAY DEVICE
The display device described in the patent application consists of pixel electrodes, reflective openings defined by a first definition layer, reflective electrodes on the pixel electrodes, a second definition layer defining pixel openings, light emitting layers, a common electrode, an encapsulation layer, a capping layer, and a low refractive index layer.
- Pixel electrodes are spaced apart from each other.
- Reflective openings are defined by a first definition layer, opening a first area of each pixel electrode.
- Reflective electrodes are disposed on the first area of each pixel electrode, extending to the first definition layer.
- A second definition layer is placed on the first definition layer, defining pixel openings that open a second area of each reflective electrode.
- Light emitting layers are positioned on the second area of each reflective electrode within the pixel openings.
- A common electrode overlaps the light emitting layers and the second definition layer in plan view.
- An encapsulation layer covers the common electrode in plan view.
- A capping layer is placed on the encapsulation layer.
- A low refractive index layer is disposed on the capping layer.
Potential Applications: - This technology can be used in the manufacturing of high-resolution displays for electronic devices. - It can be applied in the development of energy-efficient and vibrant display screens for various consumer electronics.
Problems Solved: - Provides a structure for efficient light emission in display devices. - Enables the creation of displays with improved brightness and color accuracy.
Benefits: - Enhanced display quality with better brightness and color reproduction. - Energy-efficient design for longer battery life in electronic devices.
Commercial Applications: Title: Advanced Display Technology for High-Resolution Screens This technology can be utilized in smartphones, tablets, laptops, and other electronic devices requiring high-quality display screens. The market implications include improved user experience, increased demand for devices with superior display capabilities, and potential growth in the consumer electronics industry.
