DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240196710 titled 'DISPLAY DEVICE
The display device described in the patent application includes pixel electrodes, reflective openings defined by a first definition layer, reflective electrodes on the pixel electrodes, pixel openings defined by a second definition layer, light emitting layers within the pixel openings, a common electrode overlapping the light emitting layers, and encapsulation layers for protection.
- Pixel electrodes are spaced apart from each other.
- Reflective electrodes extend from the pixel electrodes to the first definition layer.
- Light emitting layers are disposed on the reflective electrodes within the pixel openings.
- A common electrode overlaps the light emitting layers and the second definition layer.
- An encapsulation layer protects the components.
- A capping layer and a low refractive index layer are also included in the display device.
Potential Applications: - This technology can be used in high-resolution displays for smartphones, tablets, and televisions. - It can also be applied in augmented reality (AR) and virtual reality (VR) devices for enhanced visual experiences.
Problems Solved: - The technology addresses the need for improved display quality and efficiency in electronic devices. - It provides a solution for reducing power consumption and enhancing brightness in displays.
Benefits: - Enhanced display quality and resolution. - Reduced power consumption for longer battery life. - Improved brightness and visibility in various lighting conditions.
Commercial Applications: - The technology can be utilized by display manufacturers to produce high-quality screens for consumer electronics. - It can also be integrated into automotive displays, medical devices, and wearable technology for diverse commercial applications.
Questions about the technology: 1. How does the reflective electrode contribute to the overall display performance? 2. What are the advantages of using a common electrode in this display device design?
Original Abstract Submitted
a display device includes pixel electrodes spaced apart from each other, a first definition layer defining reflective openings opening a first area of each of the pixel electrodes, reflective electrodes disposed on the first area of each of the pixel electrodes, extending from the first area of each of the pixel electrodes to the first definition layer, and spaced apart from each other, a second definition layer disposed on the first definition layer and defining pixel openings opening a second area of each of the reflective electrodes, light emitting layers disposed on the second area of each of the reflective electrodes within the pixel openings, a common electrode overlapping the light emitting layers and the second definition layer in plan view, an encapsulation layer overlapping the common electrode in plan view, a capping layer disposed on the encapsulation layer, and a low refractive index layer disposed on the capping layer.
